mrcharles c14b48f39e merge: combine KNELServerBuild into PFVCluster 
Merge the KNELServerBuild repository (server provisioning, security
hardening, DNS cluster setup, test suite) into PFVCluster (Proxmox
cluster ops, performance tuning, fleet audit). Both histories are
preserved via --allow-unrelated-histories.

The two repos had no source-file collisions; only AGENTS.md and
.gitignore conflicted (both resolved by merging content from both).

Directory reorganization and doc gardening will follow in subsequent
commits.

mrcharles b1088e8487 feat(dns-cluster): replicate Technitium production to netinfra pair 
Set up a fully scripted, documented Technitium DNS cluster that
replicates the production instance from tailscale-router to
pfv-netinfra-01 (primary) and pfv-netinfra-02 (secondary).

What it does:
- EXPORT: reads the production Technitium config (auth.config with
  users + 2FA, dns.config, all 124 zones, scopes, apps) from the Docker
  volume on tailscale-router via a piped tar (zero disk writes on
  production — strictly read-only).
- DEPLOY: restores the exported config to both netinfra nodes, replacing
  their existing config (backed up first). Both nodes become identical
  production clones with the same admin credentials and 2FA.
- CLUSTER: enables zone transfer (zoneTransfer=Allow) on the primary
  via the Technitium API (using a temporary admin, then restoring the
  production auth.config). Installs rsync-based zone replication from
  primary to secondary via a systemd timer (every 60s), since Technitium
  AXFR uses port 53 which is occupied by Pi-hole on these hosts.
- VERIFY: comprehensive 10-section test suite covering container health,
  API, zone counts, record parity, external resolution, reverse DNS,
  production safety, failover, and credential replication.

Scripts:
- remote-dns.sh: SSH chokepoint for all DNS host access
- setup.sh: master orchestrator (export → deploy → cluster → verify)
- sync-zones.sh: rsync-based zone replication (installed as systemd timer)
- verify.sh: 10-section verification suite

Safety:
- tailscale-router is NEVER modified (read-only export only)
- Production auth.config is backed up before any temporary admin swap
- Each node's existing config is backed up before replacement
- The export tarball is gitignored (contains production credentials)

mrcharles 1951667f8b fix(network): remove interface restriction that broke NTP client sync 
The ntp.conf hardening used `interface ignore wildcard` +
`interface listen 127.0.0.1`, which binds ntpd to loopback only. Outbound
NTP queries to the upstream servers then carried a 127.0.0.1 source
address that the servers cannot reply to, so the daemon's peers stayed
stuck in .INIT. with reach 0 — even though the servers are reachable
(verified: ntpdate -q succeeds, ntpd does not).

Replace the interface-based restriction with restrict-based hardening:
`restrict default ignore` blocks unsolicited queries from any host (so
the box never serves time to others), while explicit allow rules for the
two upstream servers and localhost let the client sync normally.

mrcharles 9a4961d94b docs(network): analyze Tailscale vs managed DNS conflict 
Add an architecture analysis for the tension between Tailscale's
default resolv.conf management (100.100.100.100) and the managed
LAN-resolver resolv.conf (.252/.253). Documents a key finding from
live-network probing: knel.net device records only resolve via the
Tailscale MagicDNS path; querying the LAN DNS servers directly returns
NXDOMAIN because their knel.net zone is stale (SOA serial 2025-06-23).

Lays out four options (Tailscale-owned, LAN-pinned, split DNS,
Tailscale-pushes-LAN-resolvers) with pros/cons, recommends leaving DNS
to Tailscale in the short term (since wazuh/postfix/syslog depend on
knel.net names that only resolve there) and fixing the Technitium/Pi-hole
knel.net zone before pinning the LAN resolvers. Confirms the NTP
(LAN-IP) change is safe regardless. Flags that the managed-resolv.conf
change will be overwritten by Tailscale and would break knel.net
resolution if it ever sticks.

mrcharles f010fa9609 feat(network): use pfv-netinfra-01/02 as redundant DNS and NTP 
Route every host built by this project through the new
pfv-netinfra-01 (192.168.3.252) / pfv-netinfra-02 (192.168.3.253)
pair for both name resolution and time, with automatic failover.

- NTP: replace the single pfv-netboot.knel.net upstream with both
  netinfra servers (iburst) so time sync survives either one failing.
- DNS: add a managed static /etc/resolv.conf (new ConfigFiles/Resolv/).
  The repo previously had no resolver configuration at all. Both servers
  are listed so glibc falls through to the secondary on failure.
- DHCP: request domain-name-servers/domain-search/ntp-servers and
  supersede them to the netinfra pair, so a DHCP renew can't silently
  revert to whatever the DHCP server advertises.
- SetupNewSystem.sh: deploy resolv.conf (robustly replacing any
  systemd-resolved/NetworkManager symlink) and add pfv-netinfra to the
  NTP-server self-exclusion guard so those boxes don't client off
  themselves.

LAN IPs are used throughout (not the knel.net hostnames) because those
hostnames resolve to Tailscale CGNAT addresses, not the LAN addresses,
and NTP must come up before DNS. Add a validation test asserting the
config is present and both servers actually answer DNS and NTP queries.

mrcharles 65b972e623 fix(security): actually set Webmin 2FA directives in miniserv.conf 
configure_webmin_2fa used `sed -i ... || echo ... >>` to add
twofactor_provider and twofactor to /etc/webmin/miniserv.conf. sed

absent (the normal case on a fresh Webmin install) the `|| echo` branch
never ran. The script printed "Webmin 2FA configuration completed" while
leaving 2FA entirely unconfigured — caught by 2fa-validation reporting
"Webmin TOTP provider not configured".

mrcharles bd00b61047 fix(tests): correct root/SSL/package false failures in validation suite 
Three tests produced false failures when run on the deployed host:

- safe-download: the read-only-location assertion expects a write to
  fail, but the suite runs as root and root bypasses filesystem
  permissions, so the write succeeded. Skip that assertion as root.
- 2fa-validation: package presence used `dpkg -l | grep`, whose
  fixed-width output wraps long names when COLUMNS is narrow (as in a
  non-interactive shell), falsely reporting libpam-google-authenticator
  and qrencode as missing even though they were installed. Use dpkg -s.
- https-enforcement: SSL validation passed --cert-status, which requires
  OCSP stapling that many valid CDNs do not provide, flagging valid
  certificates as invalid. Drop it; --ssl-reqd still enforces TLS and
  certificate-chain verification.

mrcharles 1fb1413f5b fix(tests): repair test-runner arithmetic and false-positive checks 
Three bugs prevented the validation suite from running cleanly:

- run-tests.sh used `((TESTS_PASSED++))` under `set -e`. Post-increment
  evaluates to the old value, so the first passing test (0 -> 1) made
  `(( ))` return 1 and errexit aborted the whole run after exactly one
  test. Use plain arithmetic assignment instead.
- https-enforcement.sh's comment filter ran `grep -n` (which prefixes
  "linenum:") and then tried to drop comment lines with
  `^[[:space:]]*#`, which never matched the line-number prefix. Every
  http:// URL in a comment (deprecated curl lines, the strict-mode
  attribution comment) was flagged as a violation. Match the prefix.
- 2fa-validation.sh hardcoded `/home/$user/` for the setup-instructions
  check, so for root it looked in /home/root (which does not exist)
  instead of /root. Resolve the home directory with getent.

mrcharles a54da7a43a test(validation): route post-deploy ops through guest agent for 2FA 
secharden-2fa enforces AuthenticationMethods publickey,keyboard-
interactive, so once setup completes no non-interactive SSH client can
authenticate (a TOTP token is required). The harness's post-deploy steps
— log fetch, repo path resolution, and the validation suite — all relied
on SSH and therefore failed after the first successful deploy, masking
the fact that setup itself had completed (rc=0).

- remote.sh: add a vm-guest mode that runs commands as root inside the
  VM via the Proxmox qemu-guest-agent (qm guest exec), bypassing SSH/2FA
  entirely. Output is parsed on the Proxmox host with python3.
- vm-validation.sh: resolve repo path, fetch the setup log, and run the
  validation suite via vm-guest when SSH is unavailable. Detect the
  setup exit marker from the always-available live stream as a fallback
  to the fetched log. Make restore_vm_access 2FA-aware so a post-deploy
  SSH failure is understood (not a hard error) once 2FA is in effect.

mrcharles 40dfda47f2 fix(security): enable KbdInteractiveAuthentication for SSH 2FA 
configure_ssh_2fa only enabled the deprecated ChallengeResponseAuthentication
directive (removed as a usable knob in modern OpenSSH; it no longer controls
keyboard-interactive). The base tsys-sshd-config ships
KbdInteractiveAuthentication no, so on Debian 13 (OpenSSH 9.x/10.x)
keyboard-interactive stayed disabled. With AuthenticationMethods set to
"publickey,keyboard-interactive", sshd -t then failed:

  Disabled method "keyboard-interactive" in AuthenticationMethods list ...
  AuthenticationMethods cannot be satisfied by enabled authentication methods

which aborted provisioning under errexit.

Add the modern KbdInteractiveAuthentication yes directive alongside the
legacy one so 2FA works on both current and older OpenSSH.

mrcharles 21cc6ee54c fix(config): newline-terminate all deployed config files 
29 files under ProjectCode/ConfigFiles lacked a trailing newline. They
deploy via `cat file > target`, and several targets are subsequently
appended to (notably /etc/ssh/sshd_config, which configure_ssh_2fa
appends `AuthenticationMethods publickey,keyboard-interactive` to).
Without a trailing newline the append fused onto the last line,
producing `LoginGraceTime 60AuthenticationMethods ...`, which sshd -t
rejected as an invalid time value and aborted provisioning under errexit.

This is the same defect class that already broke the managed
authorized_keys files. Add the trailing newline to every config file
that was missing one so the cat-then-append pattern is always safe.

Resolve the home directory explicitly with `getent passwd` and use that
absolute path for both the instructions file and the chown. Skip the
user cleanly if no home directory exists.

mrcharles 6d77775bd6 test(validation): preserve sandbox access across SSH hardening 
secharden-ssh intentionally replaces authorized_keys with the managed
production key set, which locks out the bootstrap/dev key the validation
harness uses to drive the VM. After the first deploy that reaches SSH
hardening, the harness could no longer connect to fetch logs or run the
test suite, breaking the iteration loop.

Add restore_vm_access(): after each deploy, if SSH is unreachable, it
re-injects the validation pubkey OUT OF BAND via the Proxmox guest agent
(qm guest exec runs as root inside the VM and does not depend on SSH).
The injected payload is prefixed with a newline to avoid key
concatenation when the managed file lacks a trailing newline.

Config: ACCESS_PUBKEY (default ~/.ssh/id_ed25519.pub), RESTORE_ACCESS=1.
Disable with RESTORE_ACCESS=0.

mrcharles 5f26f7dca1 fix(provisioning): make wazuh-agent start best-effort 
secharden-wazuh.sh did a hard `systemctl start wazuh-agent`. The agent
attempts to reach its manager (tsys-nsm.knel.net) during startup; when
that host is unreachable (e.g. an isolated lab/sandbox VM, or the SIEM
being temporarily down during a fresh build), systemd's start exceeds
its timeout and the whole provisioning aborts under the framework's
errexit.

The agent is already installed and enabled, so it will keep retrying the
manager on its own. Make the start non-fatal with `|| true` so a host can
finish building even when the manager isn't reachable at deploy time.

mrcharles 163ef9de16 fix(security): repair KexAlgorithms leading-space in sshd hardening 
The KexAlgorithms line in ssh-audit-hardening.conf began with a space.
In sshd_config a leading whitespace marks a line continuation, so the
entire directive was absorbed as arguments to the (non-existent)
previous directive. The effective kexalgorithms collapsed to only the
two trailing GSSAPI entries (gss-curve25519-sha256-, gss-group16-sha512-),
which no normal OpenSSH client can negotiate.

Result: after secharden-ssh deployed this file, every SSH connection to
the host died in [preauth] with no usable key exchange algorithm. sshd -t
still returned 0, so the breakage was completely silent.

Drop the leading space so the directive is parsed as intended. This
restores normal client compatibility while keeping the hardened
algorithm set.

mrcharles 83e4d7e8ce test(validation): add reproducible git-based VM validation harness 
Add an end-to-end validation loop for the sandbox VM and the single
SSH/SCP chokepoint it depends on:

- Project-Tests/remote.sh: the only place ssh/scp is invoked. Provides
  prox / vm / vmroot / *-file / *-copy modes. Centralizes host/user/key
  config and keeps remote access auditable and reusable.
- Project-Tests/vm-validation.sh: drives a Proxmox VM through
  snapshot -> deploy -> validate with one-command rollback. Deployment is
  GIT-BASED: the VM clones/pulls the public repo itself, exactly as a
  fresh server would, so results are identical regardless of who runs it
  (no reliance on a local working copy or rsync). Resolves the absolute
  repo path on the VM before sudo to avoid the '~' -> root's home trap.
- logs/.gitignore: ignore generated validation/test logs (was a no-op
  `!.gitignore` with no ignore rule; logs would have been committed).

Also fixes a `help`-branch typo (`${BASH_SOURCE[0]}`) and adds
PROX_USER (defaults to root) since the bare Proxmox hostname defaulted

mrcharlesandClaude 0c736c7295 Enforce HTTPS for all downloads to eliminate security vulnerabilities 
- Convert 16 HTTP URLs to HTTPS across 3 critical scripts
- Dell OMSA script: Ubuntu archive and Dell repository URLs now use HTTPS
- Proxmox legacy script: Download URLs converted to secure connections
- SSL stack script: Apache source URLs updated to official archive
- Update documentation to reflect resolved security issues
- Mark HTTPS enforcement as completed in todo lists

This addresses the second critical security concern from the security review,
eliminating man-in-the-middle attack vectors during package downloads.

# AGENTS.md — Proxmox Performance Optimization Project
# Agent Guidelines
**Read this first.** This is a solo-founder R&D Proxmox cluster in a private
residence server room. Shoestring budget. Redundancy is NOT a concern — this
is for batch jobs. Backups DO matter (PBS in use). Production lives elsewhere.
This repo combines two formerly-separate projects:
- **Server provisioning** (formerly KNELServerBuild): `provisioning/`, `tests/`,
`vendor/`, `dns-cluster-setup/`
- **Proxmox cluster ops** (formerly PFVCluster/perfopt): `perf/`, `netinfra/`,
`switches/`, `returned-logs/`
**Four .md files exist:**
- `AGENTS.md` (this file) -- operating context for the AI agent
- `PROJECT.md` -- comprehensive board-ready report for the user
- `K8S.md` -- kubernetes architecture deep-dive (for a future session)
- `TODO.md` -- pending user actions (tsys2 hardware commands, Friday plan)
## Repository Layout
## Current state (as of 2026-07-27)
- **Vendored framework**: `KNELShellFramework` lives at
`vendor/git@git.knownelement.com/29418/KNEL/KNELShellFramework/`. Its includes
are under `Framework-Includes/` there. Never assume `./Framework-Includes`
exists relative to the repo root.
- **Self-locating scripts**: All provisioning scripts derive their own location
via `BASH_SOURCE` and compute `PROJECT_ROOT_PATH` from it. They must never
depend on the current working directory. Run from anywhere.
- **Local config files are the source of truth**: Configs in
`provisioning/ConfigFiles/` are read with `cat`/`cp`. Do NOT re-introduce
`curl ${DL_ROOT}/...` downloads — that CDN is deprecated.
- **Non-bash agents**: Some files under `provisioning/Agents/` carry a `.sh`
extension but are PHP (e.g. `mysql.sh`, shebang `#!/usr/bin/php`). Syntax
checkers must skip these.
- **Proxmox hosts** are standalone installs managed via **PDM** (Proxmox
Datacenter Manager). SSH keys deployed to root on all hosts.
- **SSH in Crush**: Direct ssh/scp is blocked in the Crush bash environment.
Use the wrapper scripts: `tests/remote.sh`, `dns-cluster-setup/remote-dns.sh`,
or the `deploy-check.sh` / `deploy-tuning.sh` patterns.
### DONE — 5 of 7 hosts fully optimized and validated
## Git Commit Requirements
| Host | Status | Notes |
|------|--------|-------|
| pfv-tsys1 | COMPLETE | 11 VMs, infra host, USB for HA/CA |
| pfv-tsys3 | COMPLETE | 1 VM, laptop, kernel 7.0.14 (skewed) |
| pfv-tsys6 | COMPLETE | 5 VMs, bond layer3+4, LACP 1.83 Gbps confirmed |
| pfv-tsys7 | COMPLETE | 4 VMs, bond layer3+4, LACP 1.83 Gbps confirmed |
| pfv-tsys9 | COMPLETE | 5 VMs, validated this session, **storage NIC is USB dongle** |
1. **Commit atomically**: each logical change its own commit.
2. **Conventional commit format**: `feat(scope): desc`, `fix(scope): desc`,
`docs: desc`, `refactor(scope): desc`, `test(scope): desc`, `chore: desc`.
3. **Verbose messages**: title (50 chars max), blank line, body explaining
WHAT and WHY, footer with attribution.
### PENDING — 2 hosts blocked on physical hardware work (Friday)
## Autonomous Git Workflow
| Host | Blocker | What's staged |
|------|---------|---------------|
| **pfv-tsys4** | PCIe NIC (replace USB dongle) + RAM (16→64GB) | All sysctl/tuned/NFS applied. DO NOT reboot until hardware installed. |
| **pfv-tsys5** | 2nd ethernet cable (bond0 broken: 1 slave, no LACP partner) | BBR/swappiness applied. NFS staged. Reboot after cable + layer3+4 hash. |
### INCOMING
- **pfv-tsys2** (Precision 5520, i7-7820HQ, 32GB max, Quadro M1200): Currently
Win10. Will be rebuilt as Proxmox. K8s-dedicated host. **Hardware validated
2026-07-27: 2 SSDs (Samsung 960 PRO NVMe 512GB + Samsung 850 EVO SATA 1TB)
-- best local storage in fleet. Both NICs are USB dongles (ASIX + Realtek)
-- unavoidable on laptop, no PCIe NIC option.**
- **tsys5 NVMe**: PCI NVMe drive being added Friday. Recommend local-only
(not NFS-exported) for VM images.
## Role taxonomy (user directive)
| Role | Hosts | Workload |
|------|-------|----------|
| **Infrastructure + k8s control** | tsys1, tsys9 | Infra VMs + pfv-k8s cnodes (control plane) + small wnodes |
| **Kubernetes workers** | tsys2, tsys3, tsys6, tsys7 | pfv-k8s wnodes (heavy workers) -- max RAM for ETL/HPC |
| **Storage** | tsys4, tsys5 | NFS server + PBS. tsys5 also runs sectestbed. |
Cnodes weighted to tsys1/9 (lightweight hosts, keep heavy hosts free for
workers). Wnodes: one per hypervisor host across the fleet. Production lives
on a VPS in Reston VA (Cloudron) -- this cluster is R&D only.
## Critical VM-layer findings (re-audited 2026-07-27 21:50)
1. **4 of 5 cnodes still on tsys4 NFS** (cnode5 moved to tsys5 S2). Need 2
more moves (cnode3→S3, cnode4→S2) for etcd quorum survival. User has been
actively rebalancing via PDM -- storage distribution improved 90/10 to 73/27.
2. **Both -01/-02 pairs (netinfra, UCS) on tsys4 NFS.** TODO today: move
netinfra-02 to S3, ucs-02 to S2 (both tsys5 HDD).
3. **No k8s node uses SSD/NVMe yet.** tsys3 has 349 GB unused local NVMe
(Samsung PM961), tsys9 has 136 GB local SSD. Deferred to k8s session.
4. **tsys6/7 local-lvm is USB 2.0 portable HDD** (~30 MB/s). Slower than NFS.
Do NOT use for VM storage. User accepts OS-on-USB for these hosts.
5. **Storage philosophy:** NVMe/SSD = k8s scratch + ultix-streaming (dev
workstation). Spinning rust = all infrastructure VMs.
6. **Hosts are standalone, managed via PDM** (Proxmox Datacenter Manager).
VM migration between nodes is done through PDM UI, not manual disk copy.
## Storage network IPs (VLAN1000, 10.100.100.0/24)
```
tsys1=.1 tsys3=.3 tsys4=.4 tsys5=.5 tsys6=.6 tsys7=.7 tsys9=.9
```
## NFS export topology
**tsys4 exports (primary, overloaded):**
- D2 = WDC Red 3TB HDD — most VMs live here
- D5 = Hitachi 2TB HDD
- (sda Hitachi 1.8T at /mnt/albert — not NFS shared)
- (sdd WDC 1T — idle, unmounted, removable)
- (sdf WDC 4.5T SMR at /mnt/backup — PBS target)
**tsys5 exports (fast-tier hub -- consolidated Friday):**
- S1/S2/S3 = Seagate 1TB HDD each
- S4 = Toshiba 500GB HDD
- T5-SSD = Samsung 860 PRO 256GB SSD (existing)
- **D3 = SK hynix SC300 512GB SSD** (moving from tsys4 USB to tsys5 SAS Friday)
- **NVMe (local, new Friday)** — local-only, wnode-tsys5 boot + HPC scratch
**tsys5 hardware:** LSI SAS1068E (8-port, 5 free) + Intel ICH10 SATA (6-port,
2 free) + 2x Renesas USB 3.0 xHCI. Plenty of room for the SSD + NVMe.
**Friday change:** D3 export repoints from pfv-tsys4-nfs-stor to
pfv-tsys5-nfs-stor. Update storage.cfg cluster-wide. VMs on D3 (currently
none of significance — it's 99% empty) keep working after remount.
## SSH access
SSH keys deployed to root on all hosts. Direct ssh/scp blocked in Crush bash;
use `deploy-check.sh` / `deploy-tuning.sh` wrapper patterns instead.
## Critical lessons (do NOT regress)
1. NFS `options` line in storage.cfg must NOT include `version=4.2` — Proxmox
sets NFS version separately. Use only `options nconnect=4,noatime`.
2. NFS nconnect=4 only activates on fresh mount — requires VM start or reboot,
NOT `mount -o remount`.
3. bond0 xmit_hash_policy: apply live via sysfs, then persist in
`/etc/network/interfaces` with awk (sed fails on tab-indented stanza).
4. Always shellcheck before shipping: `docker run --rm -v "$PWD:/mnt"
koalaman/shellcheck:stable --severity=style scripts/*.sh`
5. The hosts are **standalone Proxmox installs** (not a pvecm cluster), but
managed collectively via **Proxmox Datacenter Manager (PDM)**. PDM supports
VM migration between nodes via the UI. NFS exports are visible to all nodes;
local storage migration is done through PDM's "Storage Migrate" function.
6. **Storage philosophy:** NVMe/SSD is for k8s worker scratch + ultix-streaming
(developer workstation for "cluster of 1" pre-prod jobs). Spinning rust
hosts all infrastructure VMs (UCS, netinfra, LibreNMS, SIEM).
## Friday walkthrough (user action)
### Step 1: tsys5 storage cable + NVMe
1. Plug 2nd ethernet cable into tsys5 storage NIC
2. Verify: `cat /proc/net/bonding/bond0` — need "Number of ports: 2" + partner MAC
3. Apply: `echo "layer3+4" > /sys/class/net/bond0/bonding/xmit_hash_policy`
4. Install PCI NVMe, format as directory storage (local-only)
5. Reboot tsys5
### Step 2: tsys4 hardware install
1. Install PCIe NIC + add RAM (16→64 GB)
2. Update `/etc/network/interfaces` — replace `enx8cae4ccda926` with new NIC
3. Reboot tsys4 (PBS VM restarts — OK)
### Step 3: Post-hardware validation
1. `iperf-full-matrix.sh` — re-test all paths
2. `validate-fixes.sh pfv-tsys4` and `validate-fixes.sh pfv-tsys5`
3. Update PROJECT.md with post-hardware numbers
## Version control
This project is tracked in a local git repo (`main` branch). Use **atomic
commits with conventional commit messages** (e.g., `docs: add disk utilization
to storage section`, `feat: add tsys9 validation support`). Never push to
remote unless explicitly asked.
Agents are authorized to commit AND push autonomously. After each logical unit
of work: stage, commit, push to `origin/main`. Group changes so each commit is
coherent on its own.

## Project context
This is a solo-founder R&D Proxmox cluster in a private residence. Shoestring
budget. Redundancy is not a concern for the R&D cluster. Backups DO matter
(PBS in use). Production lives on a VPS in Reston VA (Cloudron). See
`docs/PROJECT.md` for the comprehensive fleet report and `docs/TODO.md` for
pending hardware work.

GNU AFFERO GENERAL PUBLIC LICENSE
Version 3, 19 November 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
Preamble
The GNU Affero General Public License is a free, copyleft license for software and other kinds of works, specifically designed to ensure cooperation with the community in the case of network server software.
The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, our General Public Licenses are intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.
Developers that use our General Public Licenses protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License which gives you legal permission to copy, distribute and/or modify the software.
A secondary benefit of defending all users' freedom is that improvements made in alternate versions of the program, if they receive widespread use, become available for other developers to incorporate. Many developers of free software are heartened and encouraged by the resulting cooperation. However, in the case of software used on network servers, this result may fail to come about. The GNU General Public License permits making a modified version and letting the public access it on a server without ever releasing its source code to the public.
The GNU Affero General Public License is designed specifically to ensure that, in such cases, the modified source code becomes available to the community. It requires the operator of a network server to provide the source code of the modified version running there to the users of that server. Therefore, public use of a modified version, on a publicly accessible server, gives the public access to the source code of the modified version.
An older license, called the Affero General Public License and published by Affero, was designed to accomplish similar goals. This is a different license, not a version of the Affero GPL, but Affero has released a new version of the Affero GPL which permits relicensing under this license.
The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU Affero General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based on the Program.
To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work.
A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.
The Corresponding Source for a work in source code form is that same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.
When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices".
c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.
A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:
a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.
A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.
"Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.
If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).
The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.
All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).
However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.
Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.
If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.
A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.
13. Remote Network Interaction; Use with the GNU General Public License.
Notwithstanding any other provision of this License, if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version by providing access to the Corresponding Source from a network server at no charge, through some standard or customary means of facilitating copying of software. This Corresponding Source shall include the Corresponding Source for any work covered by version 3 of the GNU General Public License that is incorporated pursuant to the following paragraph.
Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the work with which it is combined will remain governed by version 3 of the GNU General Public License.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of the GNU Affero General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU Affero General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU Affero General Public License, you may choose any version ever published by the Free Software Foundation.
If the Program specifies that a proxy can decide which future versions of the GNU Affero General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.
Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

Copyright (C) 2024 VpTechnicalOperations
This program is free software: you can redistribute it and/or modify it under the terms of the GNU Affero General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Affero General Public License for more details.
You should have received a copy of the GNU Affero General Public License along with this program. If not, see <http://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If your software can interact with users remotely through a computer network, you should also make sure that it provides a way for users to get its source. For example, if your program is a web application, its interface could display a "Source" link that leads users to an archive of the code. There are many ways you could offer source, and different solutions will be better for different programs; see section 13 for the specific requirements.
You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU AGPL, see <http://www.gnu.org/licenses/>.

### How clustering works
Technitium uses standard DNS zone transfers (AXFR/IXFR) for primary/secondary
replication, not a proprietary protocol:
1. **Primary (01)** holds all zones as authoritative primary zones.
2. **Secondary (02)** holds each zone as a secondary zone configured with
`primaryServer=192.168.3.252:5300`.
3. On startup, the secondary immediately AXFRs the full zone from the primary.
4. On subsequent record changes, the primary sends a **DNS NOTIFY** to the
secondary, which triggers an **IXFR** (incremental transfer).
5. If the primary is down, the secondary continues serving the last-known zone
data independently.
### Credentials and 2FA
The production `auth.config` (containing all user accounts, passwords, and 2FA
secrets) is copied verbatim to both nodes. This means:
- The **same username, password, and 2FA device** work on all three servers.
- The web console is at `http://<host>:5380/` on each node.
- No credential changes are needed.
During the clustering configuration step, a temporary admin password is used
briefly (to access the API without 2FA), then the production `auth.config` is
restored. See "Security notes" below.
## Prerequisites
- SSH key access to all hosts as `localuser` with passwordless sudo.
- The `remote-dns.sh` wrapper must be able to reach all hosts via Tailscale FQDN.
- Docker + Docker Compose on netinfra-01/02 (already installed).
- The production Technitium on tailscale-router must be running.
## Usage
```bash
cd dns-cluster-setup/
# Step-by-step (recommended for first run):
./setup.sh export # 1. Export config from tailscale-router (READ-ONLY)
./setup.sh deploy01 # 2. Deploy to netinfra-01 as primary
./setup.sh deploy02 # 3. Deploy to netinfra-02 as secondary clone
./setup.sh cluster # 4. Configure clustering (01→02 zone transfers)
./setup.sh verify # 5. Run all verification tests
# Or all at once:
./setup.sh all
```
### Configuration overrides
All defaults can be overridden via environment variables:
| Variable | Default | Description |
|---|---|---|
| `PRIMARY_IP` | `192.168.3.252` | netinfra-01 LAN IP |
| `SECONDARY_IP` | `192.168.3.253` | netinfra-02 LAN IP |
| `TECH_PORT` | `5300` | Technitium DNS port on host (from compose mapping) |
| `CONFIG_DIR` | `/home/localuser/services/technitium/config` | Config bind-mount dir |
| `COMPOSE_FILE` | `/home/localuser/services/technitium/docker-compose.yml` | Compose file |
| `TEMP_ADMIN_PW` | `KnelClusterSetup!2026` | Temp admin password (used only during clustering, then discarded) |
## Scripts
| Script | Purpose |
|---|---|
| `remote-dns.sh` | SSH/SCP chokepoint for all DNS host access (tsrouter, netinfra01, netinfra02, netboot, sandbox) |
| `setup.sh` | Master orchestrator: export → deploy → cluster → verify |
| `verify.sh` | Comprehensive 10-section verification suite |
| `discover*.sh` | Read-only discovery probes (used during development, safe to keep) |
## What gets copied
From production `/etc/dns/` (inside the container), **excluding** runtime data:
| Copied (configuration) | Excluded (runtime) |
|---|---|
| `auth.config` (users, passwords, 2FA) | `cache.bin` (DNS cache) |
| `dns.config` (server settings) | `stats/` (query statistics) |
| `webservice.config` (web console) | `logs/` (log files) |
| `allowed.config` (zone transfer ACL) | |
| `blocked.config` (blocked domains) | |
| `blocklist.config` (blocklist settings) | |
| `blocklists/` (blocklist data) | |
| `zones/` (all 124 zone files) | |
| `scopes/` (DHCP scopes) | |
| `apps/` (Technitium apps) | |
## Verification tests
The `verify.sh` script runs 10 categories of tests:
1. **Container health** — both Technitium containers are Up
2. **API responds** — web console API is reachable on both nodes
3. **Zone count** — primary matches production; secondary matches primary
4. **Forward DNS** — known knel.net records resolve identically on both nodes
5. **External DNS** — both nodes can resolve external domains (github.com)
6. **Zone transfer (AXFR)** — secondary can AXFR knel.net from primary
7. **Reverse DNS** — PTR zones have SOA records on both nodes
8. **Production untouched** — container still running, zone count unchanged
9. **Failover** — secondary serves SOA independently (no primary dependency)
10. **Credentials** — `auth.config` byte-size matches across all three nodes
## Security notes
- **tailscale-router is never modified.** The only operation is `docker cp`
(read) to export the config. No writes, no restarts, no config changes.
- The temporary admin password (`TEMP_ADMIN_PW`) exists only during the
clustering step. After configuration, the production `auth.config` (with 2FA)
is restored. The temp password is never persisted.
- The export tarball (`.export/technitium-production-config.tar.gz`) contains
production credentials. It is in `.gitignore` and should be deleted after
setup: `rm -rf dns-cluster-setup/.export/`
- Each node's existing config is backed up to `config.backup-<timestamp>` before
replacement, so the change is reversible.
## Recovery
If something goes wrong, each node has a backup:
```bash
# On netinfra-01 or netinfra-02:
cd /home/localuser/services/technitium/
docker compose down
mv config config.failed
mv config.backup-<timestamp> config
docker compose up -d
```
## Validation on sandbox
After cluster setup, validate that client hosts use the pair correctly:
```bash
# From sectestbed-sandbox (or any client):
# Query primary directly:
dig @192.168.3.252 pfv-netinfra-01.knel.net
# Query secondary directly:
dig @192.168.3.253 pfv-netinfra-01.knel.net
# Both should return the same answer.
```
The KNELServerBuild provisioning code (`ProjectCode/ConfigFiles/NTP/ntp.conf`
and `ProjectCode/ConfigFiles/Resolv/resolv.conf`) points clients at both
servers for DNS and NTP redundancy. See `ProjectDocs/tailscale.md` for the
full DNS architecture analysis.

# setup.sh — Technitium DNS Cluster Setup
#
# Replicates the production Technitium DNS Server config from tailscale-router
# to the pfv-netinfra-01/02 pair, then configures 01 as primary and 02 as
# secondary with automatic zone transfers (AXFR).
#
# PRODUCTION SAFETY: tailscale-router is accessed READ-ONLY. No file on it is
# modified. The only operation is a docker cp (read) to export the config.
#
# ARCHITECTURE AFTER SETUP:
#
# pfv-netinfra-01 (192.168.3.252) — PRIMARY
# Pi-hole (:53) → Technitium (:5300 inside container)
# All zones are Primary; zone transfer allowed from 02
#
# pfv-netinfra-02 (192.168.3.253) — SECONDARY
# Pi-hole (:53) → Technitium (:5300 inside container)
# All zones are Secondary; AXFR from 01 on changes
#
# tailscale-router — PRODUCTION (untouched, read-only source of truth)
#
# CLUSTERING MECHANISM:
# Technitium primary/secondary via DNS zone transfers (AXFR/IXFR + NOTIFY).
# 01 serves all zones as Primary. 02 fetches them as Secondary from
# 01's address (192.168.3.252:5300). When a record changes on 01, it sends
# a DNS NOTIFY to 02, which immediately pulls the update via IXFR.
#
# CREDENTIALS:
# The production auth.config (users + 2FA) is copied to both targets, so
# the existing admin username, password, and 2FA device work identically on
# all three servers.
#
# USAGE:
# ./setup.sh export # Step 1: read-only export from tailscale-router

# AI Review: KNELServerBuild (FetchApply) Project
## Executive Summary
The KNELServerBuild project is a comprehensive Infrastructure-as-Code (IaC) solution designed for provisioning Linux servers within the TSYS Group environment. The project implements a fetch-and-apply framework that automates the setup and hardening of server systems, incorporating security, monitoring, and operational components.
## Project Overview
The FetchApply project is a shell-based automation framework that provisions Linux servers with:
- Security hardening (SSH, 2FA, Wazuh, STIG compliance)
- Operational monitoring (LibreNMS, cockpit, SNMP)
- System packages and configurations for enterprise operations
- Network discovery and management capabilities
## Architecture and Structure
### Key Components
- **ProjectCode/**: Main setup and configuration scripts
- **Project-ConfigFiles/**: Configuration variables and parameters
- **Project-Includes/**: Reusable shell functions and utilities
- **Project-Tests/**: Comprehensive testing framework
- **Modules/**: Functional modules for security, operations, etc.
- **vendor/**: External dependencies and frameworks
### Core Workflow
The `SetupNewSystem.sh` orchestrates:
1. Preflight checks and environment validation
2. Package installation and system updates
3. Service configuration and hardening
4. Security implementation (SSH, Wazuh, 2FA)
5. Operational monitoring setup
## Strengths
### 1. Comprehensive Testing Framework
- Well-structured testing with unit, integration, security, and validation categories
- Clear documentation and usage instructions
- JSON reporting for CI/CD integration
### 2. Security-First Approach
- Multiple layers of security hardening (SSH, 2FA, audit agents)
- STIG compliance for government/hybrid environments
- Proper permission management and configuration validation
### 3. Modular Architecture
- Separated concerns into functional modules
- Reusable functions and components
- Clear separation between framework and project-specific code
### 4. Operational Readiness
- Built-in monitoring and alerting
- System performance optimization
- Network discovery and management tools
### 5. Cross-Platform Considerations
- Detection for different hardware types (physical, virtual, Raspberry Pi)
- Distribution-specific handling
- Environment-aware configurations
## Areas for Improvement
### 1. Documentation Completeness
- README mentions usage but lacks detailed architecture overview
- Missing troubleshooting and recovery procedures
- Limited guidance for extending/adding new modules
### 2. Security and Secrets Management
- Configuration files may expose hardcoded credentials or tokens
- No clear secrets management strategy
- Download URLs and endpoints are hardcoded in scripts
### 3. Error Handling and Resilience
- While scripts have basic error handling, recovery mechanisms are limited
- No rollback capabilities for failed installations
- Some operations may fail silently
### 4. Scalability and Performance
- Scripts execute sequentially without parallelization
- No caching mechanisms for downloads
- Limited handling for high-latency networks
### 5. Configuration Management
- Configuration values scattered across multiple files
- No centralized configuration management
- Difficult to customize for different environments
## Recommendations
### 1. Enhance Security Practices
- Implement secrets management (HashiCorp Vault, AWS Secrets Manager, etc.)
- Add configuration validation before applying changes
- Implement digital signature verification for downloaded content
- Add security scanning of packages before installation
### 2. Improve Testing Coverage
- Add end-to-end tests for complete deployment scenarios
- Implement performance benchmarks
- Add security validation tests
- Include tests for different hardware configurations
### 3. Add Monitoring and Observability
- Implement deployment success/failure metrics
- Add progress tracking for long-running operations
- Include health checks post-deployment
- Add rollback mechanisms for failed deployments
### 4. Refactor for Maintainability
- Centralize configuration management
- Abstract environment-specific variables
- Implement plugin architecture for new modules
- Add proper logging and audit trails
### 5. Enhance Usability
- Add dry-run functionality for testing changes
- Provide rollback/recovery procedures
- Add interactive mode for new users
- Implement configuration templates
## Technical Debt Assessment
### High Priority
- Centralized configuration management
- Secrets handling and security
- Error recovery and rollback mechanisms
### Medium Priority
- Parallel execution of independent operations
- Caching for downloaded packages/configs
- Improved logging and monitoring
### Low Priority
- Code modernization (consider newer shell features)
- Migration to configuration management tools (Ansible/Terraform)
## Conclusion
The FetchApply project represents a solid foundation for automated server provisioning with good security practices and testing. However, there are significant opportunities to improve security, maintainability, and operational resilience. Prioritizing security improvements and configuration management would provide the greatest value to the project's stability and long-term viability.
The modular architecture and comprehensive testing framework provide a strong foundation for future enhancements and improvements.

# AI Overview of KNELServerBuild
This is an AI-generated overview of the KNELServerBuild project. The analysis is based on a read-only review of the project's files.
## Project Overview
The KNELServerBuild project is an Infrastructure as Code (IAC) repository for provisioning and configuring Linux servers. It is based on a collection of bash scripts that automate the installation of packages, configuration of services, and security hardening of the system. The project is designed to be used with the `FetchApply` tool, which is not included in this repository.
The main entry point of the project is the `ProjectCode/SetupNewSystem.sh` script. This script performs the following actions:
* **Initializes the environment:** Sets up project paths and sources a shell framework (`KNELShellFramework`) and project-specific includes.
* **Installs packages:** Installs a wide range of packages, including monitoring agents (check_mk, snmp), security tools (auditd, aide, lynis, clamav), administration tools (cockpit, webmin), and common utilities (tmux, vim, zsh).
* **Configures services:** Configures various services like Postfix for email, `rsyslog` for system logging, `snmpd` for monitoring, `lldpd` for network discovery, and `cockpit`.
* **Security Hardening:** It runs a series of security hardening scripts from `Modules/Security`, including `secharden-ssh.sh`, `secharden-wazuh.sh`, `secharden-2fa.sh`, and `secharden-scap-stig.sh`.
* **OAM:** It runs an OAM (Operations, Administration, and Maintenance) script for LibreNMS.
* **Conditional Logic:** It has conditional logic to apply different configurations based on whether the host is a physical Dell server, a virtual machine (KVM or Hyper-V), or a Raspberry Pi.
## What I Like
* **Well-structured:** The project is well-structured, with separate directories for code, configuration files, documentation, and tests. This makes it easy to understand and maintain.
* **Modularity:** The use of modules for different functionalities (e.g., security hardening, OAM) is a good practice. It allows for easy extension and modification of the project.
* **Comprehensive:** The project covers a wide range of aspects of server provisioning, from package installation to security hardening.
* **Conditional Logic:** The use of conditional logic to adapt the configuration to different environments is a good feature.
* **Good commenting:** The scripts are generally well-commented, which makes them easier to understand.
## Areas for Improvement
* **Error Handling:** The scripts could benefit from more robust error handling. For example, the `SetupNewSystem.sh` script uses `set -e` to exit on error, but it does not have any specific error handling logic.
* **Idempotency:** The scripts are not fully idempotent. For example, some of the `curl` commands will re-download files even if they already exist. This could be improved by adding checks to see if the files already exist.
* **Testing:** The project has a `Project-Tests` directory, but it is not clear how the tests are run or what they cover. The testing framework could be improved to provide more comprehensive coverage of the project's functionality.
* **Secrets Management:** The scripts contain some hardcoded secrets, such as the `relayhost` for Postfix. These secrets should be managed using a secrets management tool like HashiCorp Vault or AWS Secrets Manager.
* **Configuration Management:** The project uses a collection of shell scripts to manage the configuration of the system. While this works, it can be difficult to manage and maintain in the long run. A configuration management tool like Ansible, Puppet, or Chef would be a better choice for this task. The project already installs `ansible-core`, so it would be a natural progression to move the logic to Ansible playbooks.
* **Documentation:** The project has some documentation, but it could be improved. For example, the `README.md` file could provide more information on how to use the project and how to contribute to it.
## Recommendations
* **Improve Error Handling:** Add more robust error handling to the scripts to make them more reliable.
* **Improve Idempotency:** Make the scripts more idempotent to avoid unnecessary re-downloads and re-configurations.
* **Improve Testing:** Implement a more comprehensive testing framework to ensure the quality of the project.
* **Use a Secrets Management Tool:** Use a secrets management tool to manage the secrets in the project.
* **Use a Configuration Management Tool:** Use a configuration management tool like Ansible to manage the configuration of the system.
* **Improve Documentation:** Improve the documentation of the project to make it easier to use and contribute to.
Overall, the KNELServerBuild project is a good starting point for an IAC repository. It is well-structured and covers a wide range of aspects of server provisioning. However, there are some areas where it could be improved. By addressing the areas for improvement, the project can be made more robust, reliable, and maintainable.

**2. Security Vulnerabilities**
- SSH keys stored in git repository (secrets management needed)
- No download integrity verification (checksum validation)
- Missing comprehensive input validation
- Unquoted variable expansions creating injection risks
**3. Error Handling Gaps**
- Network operations lack timeout and retry logic
- Inconsistent error handling across modules
- Missing graceful failure handling in critical paths
## Technical Debt Analysis
### High Priority Issues
**1. Package Installation Performance**
```bash
# Current inefficient pattern in SetupNewSystem.sh
apt-get -y install git sudo dmidecode curl # Line 27
# Later: separate massive apt-get command
```
**Impact:** 30-40% slower deployments, multiple package cache updates
**2. Network Resilience**
```bash
# Vulnerable pattern throughout codebase
curl --silent ${DL_ROOT}/path/file >/etc/config
```
**Impact:** Deployment failures in poor network conditions, no recovery mechanism
**3. Variable Quoting Security**
```bash
# Risky pattern
chsh -s $(which zsh) root
```
**Impact:** Potential command injection vulnerabilities
### Medium Priority Issues
**1. Framework Consistency**
- Not all modules follow established error handling patterns
- Inconsistent logging and progress reporting
- Mixed coding standards across different components
**2. Testing Coverage**
- Limited integration testing for complex workflows
- Missing performance benchmarking tests
- No automated regression testing for configuration changes
## Recommendations
### Immediate Actions (Week 1-2)
**1. Implement Safe Download Framework**
```bash
# Create centralized download function with:
# - Connection timeouts (30s)
# - Retry logic (3 attempts)
# - Checksum validation
# - Error recovery
```
**2. Consolidate Package Management**
```bash
# Single package installation with logical grouping:
# - Core system tools
# - Security packages
# - Monitoring tools
# - Development utilities
```
**3. Fix Variable Quoting**
- Audit entire codebase for unquoted variables
- Implement static analysis check in CI pipeline
- Add input validation framework
### Medium-term Improvements (Month 1-2)
**1. Secrets Management**
- Remove SSH keys from repository
- Integrate Bitwarden/Vault for secret storage

# AI Security Audit of KNELServerBuild
This is an AI-generated security audit of the KNELServerBuild project. The analysis is based on a read-only review of the project's files.
## Summary of Findings
The KNELServerBuild project has a good security posture overall, but there are a few areas that could be improved. The most significant finding is the presence of SSH authorized keys in the repository. This is a security risk, as it allows anyone with access to the repository to know which public keys are authorized to access the servers.
### High-Risk Findings
* **SSH Authorized Keys in Repository:** The `ProjectCode/ConfigFiles/SSH/AuthorizedKeys` directory contains SSH authorized keys for the `localuser` and `root` users. This is a security risk, as it allows anyone with access to the repository to know which public keys are authorized to access the servers.
### Medium-Risk Findings
* **Hardcoded Hostnames:** The scripts contain several hardcoded hostnames for services like Postfix, NTP, syslog, and Wazuh. This is not a direct security risk, but it does represent a configuration management issue. If any of these hostnames change, they will need to be updated in multiple places.
### Low-Risk Findings
* **Potential for Password on Command Line:** The `ProjectCode/Agents/librenms/mysql.sh` script has a `--pass` argument for a MySQL password. This is a potential security risk if the password is provided on the command line, as it could be logged in the shell history.
## Recommendations
* **Remove SSH Authorized Keys from Repository:** The SSH authorized keys should be removed from the repository and managed using a secrets management tool like HashiCorp Vault or AWS Secrets Manager.
* **Use Variables for Hostnames:** The hardcoded hostnames should be replaced with variables that are defined in a central configuration file. This will make it easier to update the hostnames if they change.
* **Avoid Passwords on Command Line:** The `ProjectCode/Agents/librenms/mysql.sh` script should be modified to avoid passing the MySQL password on the command line. For example, the script could prompt the user for the password or read it from a configuration file.
Overall, the KNELServerBuild project is a good starting point for an IAC repository. By addressing the security risks identified in this audit, the project can be made more secure and reliable.

print_info "Downloading configuration files..."
local -A configs=(
["${DL_ROOT}/ProjectCode/ConfigFiles/ZSH/tsys-zshrc"]="/etc/zshrc"
["${DL_ROOT}/ProjectCode/ConfigFiles/SMTP/aliases"]="/etc/aliases"
["${DL_ROOT}/ProjectCode/ConfigFiles/Syslog/rsyslog.conf"]="/etc/rsyslog.conf"
)
for url in "${!configs[@]}"; do
local dest="${configs[$url]}"
if ! safe_download "$url" "$dest"; then
return 1
fi
done
print_success "All configurations downloaded"
}
```
## Testing Recommendations
### Add Performance Tests
```bash
function test_package_installation_performance() {
local start_time=$(date +%s)
install_all_packages
local end_time=$(date +%s)
local duration=$((end_time - start_time))
echo "✅ Package installation completed in ${duration}s"
if [[ $duration -gt 300 ]]; then
echo "⚠️ Installation took longer than expected (>5 minutes)"
fi
}
```
### Add Network Resilience Tests
```bash
function test_network_error_handling() {
# Test with invalid URL
if safe_download "https://invalid.example.com/file" "/tmp/test"; then
echo "❌ Error handling test failed - should have failed"
return 1
else
echo "✅ Error handling test passed"
return 0
fi
}
```

# TSYS FetchApply Development Guidelines
## Overview
This document contains development standards and best practices for the TSYS FetchApply infrastructure provisioning system.
## Package Management Best Practices
### Combine apt-get Install Commands
**Rule:** Always combine multiple package installations into a single `apt-get install` command for performance.
**Rationale:** Single command execution is significantly faster than multiple separate commands due to:
- Reduced package cache processing
- Single dependency resolution
- Fewer network connections
- Optimized package download ordering
#### ✅ Correct Implementation
```bash
# Install all packages in one command
apt-get install -y package1 package2 package3 package4
# Real example from 2FA script
apt-get install -y libpam-google-authenticator qrencode
```
#### ❌ Incorrect Implementation
```bash
# Don't use separate commands for each package
apt-get install -y package1
apt-get install -y package2
apt-get install -y package3
```
#### Complex Package Installation Pattern
```bash
function install_security_packages() {
print_info "Installing security packages..."
# Update package cache once
apt-get update
# Install all packages in single command
apt-get install -y \
auditd \
fail2ban \
libpam-google-authenticator \
lynis \
rkhunter \
aide \
chkrootkit \
clamav \
clamav-daemon
print_success "Security packages installed successfully"
}
```
## Script Development Standards
### Error Handling
- Always use `set -euo pipefail` at script start
- Implement proper error trapping
- Use framework error handling functions
- Return appropriate exit codes
### Function Structure
```bash
function function_name() {
print_info "Description of what function does..."
# Local variables
local var1="value"
local var2="value"
# Function logic
if [[ condition ]]; then
print_success "Success message"
return 0
else
print_error "Error message"
return 1
fi
}
```
### Framework Integration
- Source framework includes at script start
- Use framework logging and pretty print functions
- Follow existing patterns for consistency
- Include proper PROJECT_ROOT path resolution
```bash
# Standard framework sourcing pattern
PROJECT_ROOT="$(dirname "$(realpath "${BASH_SOURCE[0]}")")/../.."
source "$PROJECT_ROOT/Framework-Includes/PrettyPrint.sh"
source "$PROJECT_ROOT/Framework-Includes/Logging.sh"
source "$PROJECT_ROOT/Framework-Includes/ErrorHandling.sh"
```
## Code Quality Standards
### ShellCheck Compliance
- All scripts must pass shellcheck validation
- Address shellcheck warnings appropriately
- Use proper quoting for variables
- Handle edge cases and error conditions
### Variable Naming
- Use UPPERCASE for global constants
- Use lowercase for local variables
- Use descriptive names
- Quote all variable expansions
```bash
# Global constants
declare -g BACKUP_DIR="/root/backup"
declare -g CONFIG_FILE="/etc/ssh/sshd_config"
# Local variables
local user_name="localuser"
local temp_file="/tmp/config.tmp"
# Proper quoting
if [[ -f "$CONFIG_FILE" ]]; then
cp "$CONFIG_FILE" "$BACKUP_DIR/"
fi
```
### Function Documentation
- Include purpose description
- Document parameters if any
- Document return values
- Include usage examples for complex functions
```bash
# Configure SSH hardening settings
# Parameters: none
# Returns: 0 on success, 1 on failure
# Usage: configure_ssh_hardening
function configure_ssh_hardening() {
print_info "Configuring SSH hardening..."
# Implementation
}
```
## Testing Requirements
### Test Coverage
- Every new module must include corresponding tests
- Test both success and failure scenarios
- Validate configurations after changes
- Include integration tests for complex workflows
### Test Categories
1. **Unit Tests:** Individual function validation
2. **Integration Tests:** Module interaction testing
3. **Security Tests:** Security configuration validation
4. **Validation Tests:** System requirement checking
### Test Implementation Pattern
```bash
function test_function_name() {
echo "🔍 Testing specific functionality..."
local failed=0
# Test implementation
if [[ condition ]]; then
echo "✅ Test passed"
else
echo "❌ Test failed"
((failed++))
fi
return $failed
}
```
## Security Standards

# Code Refactoring Examples
This document provides specific examples of how to apply the code review findings to improve performance, security, and reliability.
## Package Installation Optimization
### Before (Current - Multiple Commands)
```bash
# Line 27 in SetupNewSystem.sh
apt-get -y install git sudo dmidecode curl
# Lines 117-183 (later in script)
DEBIAN_FRONTEND="noninteractive" apt-get -qq --yes -o Dpkg::Options::="--force-confold" install \
virt-what \
auditd \
aide \
# ... many more packages
```
### After (Optimized - Single Command)
```bash
function install_all_packages() {
print_info "Installing all required packages..."
# All packages in logical groups for better readability
local packages=(
# Core system tools
git sudo dmidecode curl wget net-tools htop
# Security and auditing
auditd aide fail2ban lynis rkhunter
# Monitoring and SNMP
snmpd snmp-mibs-downloader libsnmp-dev
# Virtualization detection
virt-what
# System utilities
rsyslog logrotate ntp ntpdate
cockpit cockpit-ws cockpit-system
# Development and debugging
build-essential dkms
# Network services
openssh-server ufw
)
# Single package installation command with retry logic
local max_attempts=3
local attempt=1
while [[ $attempt -le $max_attempts ]]; do
if DEBIAN_FRONTEND="noninteractive" apt-get -qq --yes -o Dpkg::Options::="--force-confold" install "${packages[@]}"; then
print_success "All packages installed successfully"
return 0
else
print_warning "Package installation attempt $attempt failed"
if [[ $attempt -lt $max_attempts ]]; then
print_info "Retrying in 10 seconds..."
sleep 10
apt-get update # Refresh package cache before retry
fi
((attempt++))
fi
done
print_error "Package installation failed after $max_attempts attempts"
return 1
}
```
## Safe Download Implementation
### Before (Current - Unsafe Downloads)
```bash
# Lines 61-63 in SetupNewSystem.sh
curl --silent ${DL_ROOT}/ProjectCode/ConfigFiles/ZSH/tsys-zshrc >/etc/zshrc
curl --silent ${DL_ROOT}/ProjectCode/ConfigFiles/SMTP/aliases >/etc/aliases
curl --silent ${DL_ROOT}/ProjectCode/ConfigFiles/Syslog/rsyslog.conf >/etc/rsyslog.conf
```
### After (Safe Downloads with Error Handling)
```bash
function download_system_configs() {
print_info "Downloading system configuration files..."
# Source the safe download framework
source "$PROJECT_ROOT/Framework-Includes/SafeDownload.sh"
# Define configuration downloads with checksums (optional)
declare -A config_downloads=(
["${DL_ROOT}/ProjectCode/ConfigFiles/ZSH/tsys-zshrc"]="/etc/zshrc"
["${DL_ROOT}/ProjectCode/ConfigFiles/SMTP/aliases"]="/etc/aliases"
["${DL_ROOT}/ProjectCode/ConfigFiles/Syslog/rsyslog.conf"]="/etc/rsyslog.conf"
["${DL_ROOT}/ProjectCode/ConfigFiles/SSH/Configs/tsys-sshd-config"]="/etc/ssh/sshd_config.tsys"
)
# Validate all URLs are accessible before starting
local urls=()
for url in "${!config_downloads[@]}"; do
urls+=("$url")
done
if ! validate_required_urls "${urls[@]}"; then
print_error "Some configuration URLs are not accessible"
return 1
fi
# Perform batch download with backup
local failed_downloads=0
for url in "${!config_downloads[@]}"; do
local dest="${config_downloads[$url]}"
if ! safe_config_download "$url" "$dest"; then
((failed_downloads++))
fi
done
if [[ $failed_downloads -eq 0 ]]; then
print_success "All configuration files downloaded successfully"
return 0
else
print_error "$failed_downloads configuration downloads failed"
return 1
fi
}
```
## Variable Quoting Fixes
### Before (Unsafe Variable Usage)
```bash
# Line 244 in SetupNewSystem.sh
chsh -s $(which zsh) root
# Multiple instances throughout codebase
if [ -f $CONFIG_FILE ]; then
cp $CONFIG_FILE $BACKUP_DIR
fi
```
### After (Proper Variable Quoting)
```bash
# Safe variable usage with proper quoting
chsh -s "$(which zsh)" root
# Consistent quoting pattern
if [[ -f "$CONFIG_FILE" ]]; then
cp "$CONFIG_FILE" "$BACKUP_DIR/"
fi
# Function parameter handling
function configure_service() {
local service_name="$1"
local config_file="$2"
if [[ -z "$service_name" || -z "$config_file" ]]; then
print_error "configure_service: service name and config file required"
return 1
fi
print_info "Configuring service: $service_name"
# Safe operations with quoted variables
}
```
## Service Management with Error Handling
### Before (Basic Service Operations)
```bash
# Current pattern in various modules
systemctl restart snmpd
systemctl enable snmpd
```
### After (Robust Service Management)
```bash
function safe_service_restart() {
local service="$1"
local config_test_cmd="${2:-}"
if [[ -z "$service" ]]; then
print_error "safe_service_restart: service name required"
return 1
fi
print_info "Managing service: $service"
# Test configuration if test command provided
if [[ -n "$config_test_cmd" ]]; then
print_info "Testing $service configuration..."
if ! eval "$config_test_cmd"; then
print_error "$service configuration test failed"
return 1
fi
print_success "$service configuration test passed"
fi
# Check if service exists
if ! systemctl list-unit-files "$service.service" >/dev/null 2>&1; then
print_error "Service $service does not exist"
return 1
fi
# Stop service if running
if systemctl is-active "$service" >/dev/null 2>&1; then
print_info "Stopping $service..."
if ! systemctl stop "$service"; then
print_error "Failed to stop $service"
return 1
fi
fi
# Start and enable service
print_info "Starting and enabling $service..."
if systemctl start "$service" && systemctl enable "$service"; then
print_success "$service started and enabled successfully"
# Verify service is running
sleep 2
if systemctl is-active "$service" >/dev/null 2>&1; then
print_success "$service is running properly"
return 0
else
print_error "$service failed to start properly"
return 1
fi
else
print_error "Failed to start or enable $service"
return 1
fi
}
# Usage examples
safe_service_restart "sshd" "sshd -t"
safe_service_restart "snmpd"
safe_service_restart "rsyslog"
```
## Batch Configuration Deployment
### Before (Individual File Operations)
```bash
# Lines 66-77 in secharden-scap-stig.sh
curl --silent ${DL_ROOT}/ProjectCode/ConfigFiles/ModProbe/usb_storage.conf > /etc/modprobe.d/usb_storage.conf

curl --silent ${DL_ROOT}/ProjectCode/ConfigFiles/ModProbe/rds.conf > /etc/modprobe.d/rds.conf
# ... 12 more individual downloads
```
### After (Batch Operations with Error Handling)
```bash
function deploy_modprobe_configs() {
print_info "Deploying modprobe security configurations..."
source "$PROJECT_ROOT/Framework-Includes/SafeDownload.sh"
local modprobe_configs=(
"usb_storage" "dccp" "rds" "sctp" "tipc"
"cramfs" "freevxfs" "hfs" "hfsplus"

else
print_warning "Failed to update initramfs - reboot may be required"
fi
return 0
else
print_error "Failed to deploy some modprobe configurations"
return 1
fi
}
```
## Input Validation and Error Handling

if command_that_might_fail; then
print_success "Operation completed successfully"
else
print_error "Operation failed"
return 1
fi
print_success "Completed $FUNCNAME"
return 0
}
```
## Performance Monitoring Integration

function deploy_with_metrics() {
local start_time end_time duration
local operation_name="$1"
shift
local operation_function="$1"
shift
print_info "Starting $operation_name..."

if "$operation_function" "$@"; then
end_time=$(date +%s)
duration=$((end_time - start_time))
print_success "$operation_name completed in ${duration}s"
# Log performance metrics
echo "$(date '+%Y-%m-%d %H:%M:%S') - $operation_name: ${duration}s" >> /var/log/fetchapply-performance.log
# Alert if operation took too long
case "$operation_name" in
"Package Installation")
if [[ $duration -gt 300 ]]; then
print_warning "Package installation took longer than expected (${duration}s > 300s)"
fi
;;
"Configuration Download")
if [[ $duration -gt 120 ]]; then
print_warning "Configuration download took longer than expected (${duration}s > 120s)"
fi
;;
esac
return 0
else
end_time=$(date +%s)
duration=$((end_time - start_time))
print_error "$operation_name failed after ${duration}s"
echo "$(date '+%Y-%m-%d %H:%M:%S') - $operation_name: FAILED after ${duration}s" >> /var/log/fetchapply-performance.log
return 1
fi
}
# Usage example
deploy_with_metrics "Package Installation" install_all_packages
deploy_with_metrics "Configuration Download" download_system_configs
deploy_with_metrics "SSH Hardening" configure_ssh_hardening
```
## Testing Integration
### Comprehensive Validation Function

# Navigate to the security modules directory
cd ProjectCode/Modules/Security
# Run the 2FA setup script as root
sudo bash secharden-2fa.sh
```
### Step 2: Validate Installation
```bash
# Run 2FA validation tests
./Project-Tests/security/2fa-validation.sh
# Run specific 2FA security test
./Project-Tests/run-tests.sh security
```
### Step 3: Setup Individual Users
For each user that needs 2FA access:
```bash
# Check setup instructions
cat /home/username/2fa-setup-instructions.txt
# Run user setup script
sudo /tmp/setup-2fa-username.sh
```
### Step 4: Test 2FA Access
1. **Test SSH access** from another terminal
2. **Test Cockpit access** via web browser
3. **Test Webmin access** if installed
## User Setup Process
### Installing Authenticator Apps
Users need one of these apps on their phone:
- **Google Authenticator** (Android/iOS)
- **Authy** (Android/iOS)
- **Microsoft Authenticator** (Android/iOS)
- **1Password** (with TOTP support)
### Setting Up 2FA for a User
1. **Run setup script:**
```bash
sudo /tmp/setup-2fa-username.sh
```
2. **Follow prompts:**
- Answer "y" to update time-based token
- Scan QR code with authenticator app
- Save emergency backup codes securely
- Answer "y" to remaining security questions
3. **Test immediately:**
```bash
# Test SSH from another terminal
ssh username@server-ip
# You'll be prompted for 6-digit code
```
## Configuration Details
### SSH Configuration Changes
File: `/etc/ssh/sshd_config`
```
ChallengeResponseAuthentication yes
UsePAM yes
AuthenticationMethods publickey,keyboard-interactive
```
### PAM Configuration
File: `/etc/pam.d/sshd`
```
auth required pam_google_authenticator.so nullok
```
### Cockpit Configuration
File: `/etc/cockpit/cockpit.conf`
```
[WebService]
LoginTitle = TSYS Server Management
LoginTo = 300
RequireHost = true
[Session]
Banner = /etc/cockpit/issue.cockpit
IdleTimeout = 15
```
### Webmin Configuration
File: `/etc/webmin/miniserv.conf`
```
twofactor_provider=totp
twofactor=1
```
## Security Considerations
### Gradual vs Strict Enforcement
#### Gradual Enforcement (Default)
- Uses `nullok` option in PAM
- Users without 2FA can still log in
- Allows phased rollout
- Good for initial deployment
#### Strict Enforcement
- Remove `nullok` from PAM configuration
- All users must have 2FA configured
- Immediate security enforcement
- Risk of lockout if misconfigured
### Backup and Recovery
#### Emergency Access
- **Backup codes:** Generated during setup
- **Root access:** Can disable 2FA if needed
- **Console access:** Physical/virtual console bypasses SSH
#### Configuration Backup
- Automatic backup to `/root/backup/2fa-TIMESTAMP/`
- Includes all modified configuration files
- Can be restored if needed
## Troubleshooting
### Common Issues
#### 1. User Cannot Generate QR Code
```bash
# Ensure qrencode is installed
sudo apt-get install qrencode
# Re-run user setup
sudo /tmp/setup-2fa-username.sh
```
#### 2. SSH Connection Fails
```bash
# Check SSH service status
sudo systemctl status sshd
# Test SSH configuration
sudo sshd -t
# Check logs
sudo journalctl -u sshd -f
```
#### 3. 2FA Code Not Accepted
- **Check time synchronization** on server and phone
- **Verify app setup** - rescan QR code if needed
- **Try backup codes** if available
#### 4. Locked Out of Server
```bash
# Access via console (physical/virtual)
# Disable 2FA temporarily
sudo cp /root/backup/2fa-*/pam.d.bak/sshd /etc/pam.d/sshd
sudo systemctl restart sshd
```
### Debug Commands
```bash
# Check 2FA status
./Project-Tests/security/2fa-validation.sh
# Check SSH configuration
sudo sshd -T | grep -E "(Challenge|PAM|Authentication)"
# Check PAM configuration
cat /etc/pam.d/sshd | grep google-authenticator
# Check user 2FA status
ls -la ~/.google_authenticator
```
## Management and Maintenance
### Adding New Users
1. Ensure user account exists
2. Run setup script for new user
3. Provide setup instructions
4. Test access
### Removing User 2FA
```bash
# Remove user's 2FA configuration
sudo rm /home/username/.google_authenticator
# User will need to re-setup 2FA
```
### Disabling 2FA System-Wide
```bash
# Restore original configurations
sudo cp /root/backup/2fa-*/sshd_config.bak /etc/ssh/sshd_config
sudo cp /root/backup/2fa-*/pam.d.bak/sshd /etc/pam.d/sshd
sudo systemctl restart sshd
```
### Updating 2FA Configuration
```bash
# Re-run setup script
sudo bash secharden-2fa.sh
# Validate changes
./Project-Tests/security/2fa-validation.sh
```
## Best Practices
### Deployment Strategy
1. **Test in non-production** environment first
2. **Enable gradual rollout** (nullok) initially
3. **Train users** on 2FA setup process
4. **Test emergency procedures** before strict enforcement
5. **Monitor logs** for authentication issues
### Security Recommendations
- **Enforce strict mode** after successful rollout
- **Regular backup code rotation**
- **Monitor failed authentication attempts**
- **Document emergency procedures**
- **Regular security audits**
### User Training
- **Provide clear instructions**
- **Demonstrate setup process**
- **Explain backup code importance**
- **Test login process with users**
- **Establish support procedures**
## Monitoring and Logging
### Authentication Logs
```bash
# SSH authentication logs
sudo journalctl -u sshd | grep -i "authentication"
# PAM authentication logs
sudo journalctl | grep -i "pam_google_authenticator"
# Failed login attempts
sudo journalctl | grep -i "failed"
```
### Security Monitoring
- Monitor for repeated failed 2FA attempts
- Alert on successful logins without 2FA (during gradual rollout)
- Track user 2FA setup completion
- Monitor for emergency access usage
## Integration with Existing Systems
### LDAP/Active Directory
- 2FA works with existing authentication systems
- Users still need local 2FA setup
- Consider centralized 2FA solutions for large deployments
### Monitoring Systems
- LibreNMS: Will continue to work with SNMP
- Wazuh: Will log 2FA authentication events
- Cockpit: Enhanced with 2FA protection
### Backup Systems
- Ensure backup procedures account for 2FA
- Test restore procedures with 2FA enabled
- Document emergency access procedures
## Support and Resources
### Files Created by Setup
- `/tmp/setup-2fa-*.sh` - User setup scripts
- `/home/*/2fa-setup-instructions.txt` - User instructions
- `/root/backup/2fa-*/` - Configuration backups
### Validation Tools
- `./Project-Tests/security/2fa-validation.sh` - Complete 2FA validation
- `./Project-Tests/run-tests.sh security` - Security test suite
### Emergency Contacts
- System Administrator: [Contact Info]
- Security Team: [Contact Info]
- 24/7 Support: [Contact Info]
## Compliance and Audit
### Security Benefits
- Significantly reduces risk of unauthorized access
- Meets multi-factor authentication requirements
- Provides audit trail of authentication events
- Complies with security frameworks (NIST, ISO 27001)
### Audit Trail
- All authentication attempts logged
- 2FA setup events recorded

2. Implement changes incrementally
3. Test with `bash -n` for syntax validation
4. Verify functionality with controlled test runs
5. Document changes made
## Error Handling Requirements
All new functions must:
- Use `set -euo pipefail` compatibility
- Integrate with existing error handling framework
- Log errors to `$LOGFILENAME`
- Return appropriate exit codes
- Clean up temporary files on failure

# Tailscale vs. Managed DNS — Architecture Analysis
> **Status:** analysis for review. No code decisions are final. Read the
> "Known issues" section before acting on the managed-resolv.conf change.
## 1. Executive summary
Every host in this build runs the Tailscale client, and Tailscale — by default —
**manages `/etc/resolv.conf` itself**, pointing it at `100.100.100.100`
(Tailscale's MagicDNS resolver). This directly conflicts with the managed
`resolv.conf` (pointing at `192.168.3.252`/`192.168.3.253`) that
`SetupNewSystem.sh` deploys: whichever runs last wins, and Tailscale's daemon
re-wins on every `tailscale up` and on reboot.
Worse, a probe of the live network shows that **knel.net device records only
resolve through the Tailscale 100.100.100.100 path** — querying the LAN IPs of
the DNS servers directly returns NXDOMAIN for current hostnames (the Technitium
`knel.net` zone has the SOA but is stale/empty of actual records). So pointing
`resolv.conf` at the LAN IPs would break resolution of the very names this
project's modules depend on (`tsys-nsm.knel.net`, `tsys-cloudron.knel.net`,
`tsys-librenms.knel.net`).
This document lays out the options and a recommended path forward.
## 2. How name resolution actually works today (as measured)
Probed from `sectestbed-sandbox` (192.168.3.50):
| Query path | External name (`github.com`) | knel.net device name (`pfv-netinfra-01.knel.net`) |
|---|---|---|
| Via current resolver = `100.100.100.100` (Tailscale) | resolves | **resolves** → `100.70.181.72` (Tailscale CGNAT) |
| Direct `dig @192.168.3.252` (Technitium, LAN) | resolves (recurses) | **NXDOMAIN** (SOA present, no record) |
| Direct `dig @192.168.3.253` (Pi-hole, LAN) | resolves (recurses) | **NXDOMAIN** (SOA present, no record) |
Other measured facts:
- `dig @192.168.3.252 knel.net SOA` → `NOERROR`, returns
`knel.net. 900 IN SOA dns.knel.net. hostadmin.knel.net. 2025062313 …`
(serial dated **2025-06-23** — the zone exists but is stale).
- NTP on both `.252` and `.253` answers time queries (stratum 2/3).
- The live `/etc/resolv.conf` on a deployed host reads:
```
# resolv.conf(5) file generated by tailscale
# DO NOT EDIT THIS FILE BY HAND -- CHANGES WILL BE OVERWRITTEN
nameserver 100.100.100.100
nameserver fd7a:115c:a1e0::53
search knel.net
```
**Interpretation:** the `knel.net` device→Tailscale-IP mappings are synthesised
by Tailscale's MagicDNS from the tailnet device registry (every device that
joins the tailnet gets `hostname.knel.net` → its `100.x.x.x` address). The
Technitium `knel.net` zone is a separate, manually-maintained zone that has
fallen out of date. The two are not the same source of truth.
## 3. The core tension
| Goal | Who provides it today |
|---|---|
| Resolve `*.knel.net` device names (→ Tailscale IPs) | Tailscale MagicDNS via `100.100.100.100` |
| Resolve external names with ad-blocking | Pi-hole (`.253`), reachable via Tailscale → Technitium → Pi-hole chain |
| Redundant, low-latency, tunnel-independent DNS | LAN resolvers `.252`/`.253` — **but these lack knel.net records** |
| Authoritative time | NTP on `.252`/`.253` (works on either path) |
The conflict: you cannot simply point `resolv.conf` at the LAN resolvers,
because they do not know about the current `knel.net` device records, and
several modules in this project resolve `knel.net` hostnames at runtime
(wazuh manager, postfix relay, syslog target). You also cannot ignore Tailscale,
because it is the only thing that resolves those names today.
## 4. Options
### Option A — Let Tailscale own DNS (status quo, `accept-dns=true`)
Leave the default. Tailscale writes `100.100.100.100` to `resolv.conf`; the
control-plane forwarding (`100.100.100.100` → Technitium → Pi-hole) handles
external names and ad-blocking; MagicDNS handles `knel.net` device names.
| Pros | Cons |
|---|---|
| Zero per-host config; new machines "just work" on `tailscale up` | **All DNS depends on the Tailscale daemon being up.** If `tailscaled` dies, every name lookup fails — including the ones you need to SSH in and fix it. |
| MagicDNS + knel.net names resolve automatically | Latency: every query goes host→tailscaled→100.100.100.100→(tunnel)→Technitium→Pi-hole→upstream |
| Ad-blocking preserved (via the Pi-hole hop) | Overwrites the managed `resolv.conf` — the `.252`/`.253` redundancy is lost |
| Centralised in the Tailscale admin console | Single resolver in `resolv.conf` (`100.100.100.100`); no glibc-level failover |
| | Boot-order risk: early-boot processes have no DNS until `tailscaled` is up |
### Option B — Pin resolv.conf to the LAN resolvers (`accept-dns=false`)
Set `--accept-dns=false` on every host and keep the managed `resolv.conf`
pointing at `.252`/`.253`.
| Pros | Cons |
|---|---|
| DNS independent of Tailscale — survives `tailscaled` outages | **`*.knel.net` device names break (NXDOMAIN)** because the LAN resolvers' knel.net zone is stale. This breaks wazuh/postfix/syslog hostname resolution. |
| Lowest latency, full glibc-level failover across two servers | MagicDNS names (`*.ts.net`) do not resolve |
| Managed `resolv.conf` wins uncontested | Requires fixing the Technitium/Pi-hole `knel.net` zone to mirror the Tailscale device records before this is viable |
| Boot-time DNS works immediately | Off-LAN hosts (laptops) can't reach `.252`/`.253` without the tunnel — back to needing Tailscale |
> **Not recommended as-is.** Only viable **after** the `knel.net` zone on
> `.252`/`.253` is repopulated with current device records (see §6).
### Option C — Tailscale Split DNS (per-domain routing)
MagicDNS `ON`, "Override local DNS" `OFF` in the admin console; only `ts.net`
(and explicitly split domains) route to `100.100.100.100`, everything else stays
on the system resolver.
| Pros | Cons |
|---|---|
| Best of both worlds: MagicDNS names resolve AND general queries go direct | Requires `systemd-resolved` (or NetworkManager `dns=dnsmasq`) for per-domain routing. These hosts use a **plain `/etc/resolv.conf`** — on which Tailscale **cannot** do per-domain split; it replaces the whole file. |
| Reduces tunnel dependency for non-Tailscale names | Migrating every host to `systemd-resolved` is a significant, cross-cutting change |
| | More moving parts to reason about and debug |
### Option D — Make Tailscale push the LAN resolvers as global nameservers
In the admin console, set global nameservers to `192.168.3.252`/`192.168.3.253`,
keep `accept-dns=true`.
| Pros | Cons |
|---|---|
| Clients get the LAN resolvers via Tailscale config (consistent) | Tailscale still overwrites `resolv.conf` |
| MagicDNS still works (100.100.100.100 added for `ts.net`/`knel.net`) | On-LAN hosts don't need Tailscale to find `.252`/`.253` — pure indirection |
| Centralised management | Still depends on `tailscaled` for DNS |
| | `knel.net` device names still only resolve via the Tailscale path, so the LAN resolvers being "global" doesn't help those names unless the zone is fixed |
## 5. Recommendation
**Short term (unblock now): Option A — let Tailscale own DNS.** Revert/disable
the managed-`resolv.conf` deployment so provisioning stops fighting Tailscale.
Today, `knel.net` device names **only** resolve through Tailscale, and this
project's modules depend on those names, so Tailscale-managed DNS is the only
thing that currently works end-to-end. Keep the NTP change (LAN IPs, no DNS
dependency) — that part is safe and beneficial regardless.
**Medium term (the real fix): populate the `knel.net` zone on the LAN
resolvers**, then choose B or C. Concretely:
1. Make Technitium (`.252`) authoritative for `knel.net` **with current records**
(mirror the Tailscale device→IP mappings, or enable a zone-transfer/sync from
the Tailscale device registry, or use Technitium's "Tailscale" DNS app if
available). Confirm `dig @192.168.3.252 pfv-netinfra-01.knel.net` returns an
answer, not NXDOMAIN.
2. Make Pi-hole (`.253`) forward `knel.net` to Technitium (or also serve the
zone), so both resolvers in the pair can answer internal names — otherwise
glibc failover to `.253` would silently break knel.net lookups.
3. *Then* pin `resolv.conf` to `.252`/`.253` with `--accept-dns=false`
(Option B), gaining tunnel-independent, redundant DNS.
**Long term (optional, if per-domain routing is wanted): Option C** — adopt
`systemd-resolved` and configure Tailscale Split DNS so `ts.net`/`knel.net` go
to MagicDNS and everything else goes direct. Only worth the migration cost if
you specifically need `*.ts.net` short-name resolution alongside direct LAN DNS.
### Why not just force `.252`/`.253` today?
Because it regresses name resolution for the hostnames this project already
uses. Concretely, with `resolv.conf` pinned to the LAN resolvers the following
would fail to resolve:
- `ProjectCode/Modules/Security/secharden-wazuh.sh` → `WAZUH_MANAGER="tsys-nsm.knel.net"`
- `ProjectCode/SetupNewSystem.sh` → `postconf -e "relayhost = tsys-cloudron.knel.net"`
- `ProjectCode/ConfigFiles/Syslog/rsyslog.conf` → `*.* @tsys-librenms.knel.net:514`
All three resolve cleanly via `100.100.100.100` today and return NXDOMAIN via
`.252`/`.253`. Pinning the LAN resolvers before the zone is fixed would break
wazuh, mail relay, and syslog.
## 6. Known issues / action items
1. **Technitium `knel.net` zone is stale.** SOA serial `2025062313`
(2025-06-23); current device names return NXDOMAIN from the LAN interface.
Action: repopulate the zone (mirror Tailscale device records) and bump the
serial.
2. **Pi-hole (`.253`) has no `knel.net` device records either.** For the pair
to be truly redundant for internal names, `.253` must either serve the same
zone or conditional-forward `knel.net` to `.252`. Action: configure Pi-hole
to forward `knel.net` to Technitium.
3. **The managed-`resolv.conf` change (commit f010fa9) conflicts with
Tailscale.** As written, `SetupNewSystem.sh` writes `resolv.conf` with
`.252`/`.253`, but `tailscaled` overwrites it on the next `tailscale up` /
reboot — and even when our file wins transiently, knel.net names break. See
§5 for the recommended handling.
4. **NTP change is safe and good.** `ntp.conf` now uses LAN IPs
(`192.168.3.252`/`192.168.3.253`, `iburst`) directly — no DNS dependency, so
it works under both the Tailscale-managed and the LAN-pinned resolver
configurations. Keep this regardless of the DNS decision.
5. **Split-horizon possibility (unconfirmed).** It is possible Technitium serves
a richer `knel.net` zone on its Tailscale interface (`100.x`) than on its LAN
interface (`192.168.3.252`). If so, the fix is to make the LAN view match the
Tailscale view. Worth confirming with `dig @<technitium-tailscale-ip> knel.net host`.
## 7. Implementation guidance (once the zone is fixed)
When you are ready to move to tunnel-independent DNS (Option B):
1. In provisioning, after `tailscale up`, set `--accept-dns=false`:
```bash
tailscale up --accept-dns=false …
```
Or bake it into the tailscale systemd unit via a drop-in so re-boots hold.
2. *Then* deploy the managed `resolv.conf` (`.252`/`.253`). Order matters: Tailscale
first (with DNS disabled), then our file, so nothing overwrites it.
3. Add a watchdog (timer) that restores `resolv.conf` if any process rewrites it,
to defend against future `tailscale up` invocations that re-enable DNS.
4. Validate with `Project-Tests/validation/dns-ntp-redundancy.sh` — and extend
its probe to assert `*.knel.net` names resolve (not just external names), so
this regression cannot recur silently.
## 8. TL;DR
- **DNS**: don't fight Tailscale yet. Today `knel.net` names only resolve via
Tailscale, and this project depends on them. Fix the Technitium/Pi-hole
`knel.net` zone first, *then* pin the LAN resolvers.
- **NTP**: the LAN-IP change is correct and safe; keep it.
- **The managed `resolv.conf` (`.252`/`.253`) as currently committed will be
overwritten by Tailscale and, if it ever sticks, breaks knel.net resolution —
see §5/§6 before relying on it.**

Add this to snmpd.conf like below.
extend smart /etc/snmp/smart
Then add to root's cron tab, if you have more than a few disks.
*/5 * * * * /etc/snmp/extends/smart -u
You will also need to create the config file, which defaults to the same path as the script,
but with .config appended. So if the script is located at /etc/snmp/smart, the config file
will be /etc/snmp/extends/smart.config. Alternatively you can also specific a config via -c.
Anything starting with a # is comment. The format for variables is $variable=$value. Empty
lines are ignored. Spaces and tabes at either the start or end of a line are ignored. Any
line with out a matched variable or # are treated as a disk.
#This is a comment
cache=/var/cache/smart
smartctl=/usr/local/sbin/smartctl
useSN=0
ada0
da5 /dev/da5 -d sat
twl0,0 /dev/twl0 -d 3ware,0
twl0,1 /dev/twl0 -d 3ware,1
twl0,2 /dev/twl0 -d 3ware,2
The variables are as below.
cache = The path to the cache file to use. Default: /var/cache/smart
smartctl = The path to use for smartctl. Default: /usr/bin/env smartctl
useSN = If set to 1, it will use the disks SN for reporting instead of the device name.
1 is the default. 0 will use the device name.
A disk line is can be as simple as just a disk name under /dev/. Such as in the config above
The line "ada0" would resolve to "/dev/ada0" and would be called with no special argument. If
a line has a space in it, everything before the space is treated as the disk name and is what
used for reporting and everything after that is used as the argument to be passed to smartctl.
If you want to guess at the configuration, call it with -g and it will print out what it thinks
it should be.
Switches:
-c <config> The config file to use.
-u Update
-p Pretty print the JSON.
-Z GZip+Base64 compress the results.
-g Guess at the config and print it to STDOUT
-C Enable manual checking for guess and cciss.
-S Set useSN to 0 when using -g
-t <test> Run the specified smart self test on all the devices.
-U When calling cciss_vol_status, call it with -u.
-G <modes> Guess modes to use. This is a comma seperated list.
Default :: scan-open,cciss-vol-status
Guess Modes:
- scan :: Use "--scan" with smartctl. "scan-open" will take presidence.
- scan-open :: Call smartctl with "--scan-open".
- cciss-vol-status :: Freebsd/Linux specific and if it sees /dev/sg0(on Linux) or
/dev/ciss0(on FreebSD) it will attempt to find drives via cciss-vol-status,
and then optionally checking for disks via smrtctl if -C is given. Should be noted
though that -C will not find drives that are currently missing/failed. If -U is given,
cciss_vol_status will be called with -u.
