ZeroTierOne/service

ZeroTier One Network Virtualization Service

This is the common background service implementation for ZeroTier One, the VPN-like OS-level network virtualization service.

It provides a ready-made core I/O loop and a local HTTP-based JSON control bus for controlling the service. This control bus HTTP server can also serve the files in ui/ if this folder's contents are installed in the ZeroTier home folder. The ui/ implements a React-based HTML5 user interface which is then wrappered for various platforms via MacGap, Windows .NET WebControl, etc. It can also be used locally from scripts or via curl.

Network Virtualization Service API

The JSON API supports GET, POST/PUT, and DELETE. PUT is treated as a synonym for POST. Other methods including HEAD are not supported.

Values POSTed to the JSON API are extremely type sensitive. Things must be of the indicated type, otherwise they will be ignored or will generate an error. Anything quoted is a string so booleans and integers must lack quotes. Booleans must be true or false and nothing else. Integers cannot contain decimal points or they are floats (and vice versa). If something seems to be getting ignored or set to a strange value, or if you receive errors, check the type of all JSON fields you are submitting against the types listed below. Unrecognized fields in JSON objects are also ignored.

API requests must be authenticated via an authentication token. ZeroTier One saves this token in the authtoken.secret file in its working directory. This token may be supplied via the auth URL parameter (e.g. '?auth=...') or via the X-ZT1-Auth HTTP request header. Static UI pages are the only thing the server will allow without authentication.

A jsonp URL argument may be supplied to request JSONP encapsulation. A JSONP response is sent as a script with its JSON response payload wrapped in a call to the function name supplied as the argument to jsonp.

/status

• Purpose: Get running node status and addressing info
• Methods: GET
• Returns: { object }

Field	Type	Description	Writable
address	string	10-digit hexadecimal ZeroTier address of this node	no
publicIdentity	string	Full public ZeroTier identity of this node	no
worldId	integer	Fixed value representing the virtual data center of Earth.	no
worldTimestamp	integer	Timestamp of the last root server topology change.	no
online	boolean	Does this node appear to have upstream network access?	no
tcpFallbackActive	boolean	Is TCP fallback mode active?	no

/config

• Purpose: Get or set local configuration
• Methods: GET, POST
• Returns: { object }

No local configuration options are exposed yet.

Field

Type

Description

Writable

/network

• Purpose: Get all network memberships
• Methods: GET
• Returns: [ {object}, ... ]

Getting /network returns an array of all networks that this node has joined. See below for network object format.

/network/<network ID>

• Purpose: Get, join, or leave a network
• Methods: GET, POST, DELETE
• Returns: { object }

To join a network, POST to it. Since networks have no mandatory writable parameters, POST data is optional and may be omitted. Example: POST to /network/8056c2e21c000001 to join the public "Earth" network. To leave a network, DELETE it e.g. DELETE /network/8056c2e21c000001.

Most network settings are not writable, as they are defined by the network controller.

Field	Type	Description	Writable
nwid	string	16-digit hex network ID	no
mac	string	Ethernet MAC address of virtual network port	no
name	string	Network short name as configured on network controller	no
status	string	Network status: OK, ACCESS_DENIED, PORT_ERROR, etc.	no
type	string	Network type, currently PUBLIC or PRIVATE	no
mtu	integer	Ethernet MTU	no
dhcp	boolean	If true, DHCP may be used to obtain an IP address	no
bridge	boolean	If true, this node may bridge in other Ethernet devices	no
broadcastEnabled	boolean	Is Ethernet broadcast (ff:ff:ff:ff:ff:ff) allowed?	no
portError	integer	Error code (if any) returned by underlying OS "tap" driver	no
netconfRevision	integer	Network configuration revision ID	no
assignedAddresses	[string]	ZeroTier-managed IP address assignments as array of IP/netmask bits tuples	no
routes	[route]	ZeroTier-managed route assignments for a network. See below for a description of the route object.	no
portDeviceName	string	OS-specific network device name (if available)	no
allowManaged	boolean	Whether ZeroTier-managed IP addresses are allowed.	yes
allowGlobal	boolean	Whether globally-reachable IP addresses are allowed to be assigned.	yes
allowDefault	boolean	Whether a default route is allowed to be assigned for the network (route all traffic via ZeroTier)	yes

route objects

Field	Type	Description	Writable
target	string	Target network / netmask bits, NULL, or 0.0.0.0/0 for default route	no
via	string	Gateway IP address	no
flags	integer	Route flags	no
metric	integer	Route metric (not currently used)	no

/peer

• Purpose: Get all peers
• Methods: GET
• Returns: [ {object}, ... ]

Getting /peer returns an array of peer objects for all current peers. See below for peer object format.

/peer/<address>

• Purpose: Get information about a peer
• Methods: GET
• Returns: { object }

Field	Type	Description	Writable
address	string	10-digit hex ZeroTier address	no
versionMajor	integer	Major version of remote if known	no
versionMinor	integer	Minor version of remote if known	no

version	string	Version in major.minor.rev format	no
latency	integer	Latency in milliseconds if known	no
role	string	LEAF, HUB, or ROOTSERVER	no
paths	[object]	Array of path objects (see below)	no

Path objects describe direct physical paths to peer. If no path objects are listed, peer is only reachable via indirect relay fallback. Path object format is:

Field	Type	Description	Writable
