# DO NOT EDIT. This file is generated from Config.src # # For a description of the syntax of this configuration file, # see docs/Kconfig-language.txt. # config BUSYBOX_CONFIG_UDHCPD bool "udhcpd (21 kb)" default BUSYBOX_DEFAULT_UDHCPD help udhcpd is a DHCP server geared primarily toward embedded systems, while striving to be fully functional and RFC compliant. config BUSYBOX_CONFIG_FEATURE_UDHCPD_BASE_IP_ON_MAC bool "Select IP address based on client MAC" default BUSYBOX_DEFAULT_FEATURE_UDHCPD_BASE_IP_ON_MAC depends on BUSYBOX_CONFIG_UDHCPD help If selected, udhcpd will base its selection of IP address to offer on the client's hardware address. Otherwise udhcpd uses the next consecutive free address. This reduces the frequency of IP address changes for clients which let their lease expire, and makes consecutive DHCPOFFERS for the same client to (almost always) contain the same IP address. config BUSYBOX_CONFIG_FEATURE_UDHCPD_WRITE_LEASES_EARLY bool "Rewrite lease file at every new acknowledge" default BUSYBOX_DEFAULT_FEATURE_UDHCPD_WRITE_LEASES_EARLY depends on BUSYBOX_CONFIG_UDHCPD help If selected, udhcpd will write a new file with leases every time a new lease has been accepted, thus eliminating the need to send SIGUSR1 for the initial writing or updating. Any timed rewriting remains undisturbed. config BUSYBOX_CONFIG_DHCPD_LEASES_FILE string "Absolute path to lease file" default BUSYBOX_DEFAULT_DHCPD_LEASES_FILE depends on BUSYBOX_CONFIG_UDHCPD help udhcpd stores addresses in a lease file. This is the absolute path of the file. Normally it is safe to leave it untouched. config BUSYBOX_CONFIG_DUMPLEASES bool "dumpleases (5.1 kb)" default BUSYBOX_DEFAULT_DUMPLEASES help dumpleases displays the leases written out by the udhcpd. Lease times are stored in the file by time remaining in lease, or by the absolute time that it expires in seconds from epoch. config BUSYBOX_CONFIG_DHCPRELAY bool "dhcprelay (5.2 kb)" default BUSYBOX_DEFAULT_DHCPRELAY help dhcprelay listens for DHCP requests on one or more interfaces and forwards these requests to a different interface or DHCP server. config BUSYBOX_CONFIG_UDHCPC bool "udhcpc (24 kb)" default BUSYBOX_DEFAULT_UDHCPC help udhcpc is a DHCP client geared primarily toward embedded systems, while striving to be fully functional and RFC compliant. The udhcp client negotiates a lease with the DHCP server and runs a script when a lease is obtained or lost. config BUSYBOX_CONFIG_FEATURE_UDHCPC_ARPING bool "Verify that the offered address is free, using ARP ping" default BUSYBOX_DEFAULT_FEATURE_UDHCPC_ARPING depends on BUSYBOX_CONFIG_UDHCPC help If selected, udhcpc will send ARP probes and make sure the offered address is really not in use by anyone. The client will DHCPDECLINE the offer if the address is in use, and restart the discover process. config BUSYBOX_CONFIG_FEATURE_UDHCPC_SANITIZEOPT bool "Do not pass malformed host and domain names" default BUSYBOX_DEFAULT_FEATURE_UDHCPC_SANITIZEOPT depends on BUSYBOX_CONFIG_UDHCPC help If selected, udhcpc will check some options (such as option 12 - hostname) and if they don't look like valid hostnames (for example, if they start with dash or contain spaces), they will be replaced with string "bad" when exporting to the environment. config BUSYBOX_CONFIG_UDHCPC_DEFAULT_SCRIPT string "Absolute path to config script" default BUSYBOX_DEFAULT_UDHCPC_DEFAULT_SCRIPT depends on BUSYBOX_CONFIG_UDHCPC || BUSYBOX_CONFIG_UDHCPC6 help This script is called after udhcpc receives an answer. See examples/udhcp for a working example. Normally it is safe to leave this untouched. # udhcpc6 config is inserted here: config BUSYBOX_CONFIG_UDHCPC6 bool "udhcpc6 (21 kb)" default BUSYBOX_DEFAULT_UDHCPC6 depends on BUSYBOX_CONFIG_FEATURE_IPV6 help udhcpc6 is a DHCPv6 client config BUSYBOX_CONFIG_FEATURE_UDHCPC6_RFC3646 bool "Support RFC 3646 (DNS server and search list)" default BUSYBOX_DEFAULT_FEATURE_UDHCPC6_RFC3646 depends on BUSYBOX_CONFIG_UDHCPC6 help List of DNS servers and domain search list can be requested with "-O dns" and "-O search". If server gives these values, they will be set in environment variables "dns" and "search". config BUSYBOX_CONFIG_FEATURE_UDHCPC6_RFC4704 bool "Support RFC 4704 (Client FQDN)" default BUSYBOX_DEFAULT_FEATURE_UDHCPC6_RFC4704 depends on BUSYBOX_CONFIG_UDHCPC6 help You can request FQDN to be given by server using "-O fqdn". config BUSYBOX_CONFIG_FEATURE_UDHCPC6_RFC4833 bool "Support RFC 4833 (Timezones)" default BUSYBOX_DEFAULT_FEATURE_UDHCPC6_RFC4833 depends on BUSYBOX_CONFIG_UDHCPC6 help You can request POSIX timezone with "-O tz" and timezone name with "-O timezone". config BUSYBOX_CONFIG_FEATURE_UDHCPC6_RFC5970 bool "Support RFC 5970 (Network Boot)" default BUSYBOX_DEFAULT_FEATURE_UDHCPC6_RFC5970 depends on BUSYBOX_CONFIG_UDHCPC6 help You can request bootfile-url with "-O bootfile_url" and bootfile-params with "-O bootfile_params". comment "Common options for DHCP applets" depends on BUSYBOX_CONFIG_UDHCPD || BUSYBOX_CONFIG_UDHCPC || BUSYBOX_CONFIG_UDHCPC6 || BUSYBOX_CONFIG_DHCPRELAY config BUSYBOX_CONFIG_UDHCPC_DEFAULT_INTERFACE string "Default interface name" default BUSYBOX_DEFAULT_UDHCPC_DEFAULT_INTERFACE depends on BUSYBOX_CONFIG_UDHCPC || BUSYBOX_CONFIG_UDHCPC6 help The interface that will be used if no other interface is specified on the commandline. config BUSYBOX_CONFIG_FEATURE_UDHCP_PORT bool "Enable '-P port' option for udhcpd and udhcpc" default BUSYBOX_DEFAULT_FEATURE_UDHCP_PORT depends on BUSYBOX_CONFIG_UDHCPD || BUSYBOX_CONFIG_UDHCPC || BUSYBOX_CONFIG_UDHCPC6 help At the cost of ~300 bytes, enables -P port option. This feature is typically not needed. config BUSYBOX_CONFIG_UDHCP_DEBUG int "Maximum verbosity level (0..9)" default BUSYBOX_DEFAULT_UDHCP_DEBUG range 0 9 depends on BUSYBOX_CONFIG_UDHCPD || BUSYBOX_CONFIG_UDHCPC || BUSYBOX_CONFIG_UDHCPC6 || BUSYBOX_CONFIG_DHCPRELAY help Verbosity can be increased with multiple -v options. This option controls how high it can be cranked up. Bigger values result in bigger code. Levels above 1 are very verbose and useful for debugging only. config BUSYBOX_CONFIG_UDHCPC_SLACK_FOR_BUGGY_SERVERS int "DHCP options slack buffer size" default BUSYBOX_DEFAULT_UDHCPC_SLACK_FOR_BUGGY_SERVERS range 0 924 depends on BUSYBOX_CONFIG_UDHCPD || BUSYBOX_CONFIG_UDHCPC help Some buggy DHCP servers send DHCP offer packets with option field larger than we expect (which might also be considered a buffer overflow attempt). These packets are normally discarded. If circumstances beyond your control force you to support such servers, this may help. The upper limit (924) makes udhcpc accept even 1500 byte packets (maximum-sized ethernet packets). This option does not make udhcp[cd] emit non-standard sized packets. Known buggy DHCP servers: 3Com OfficeConnect Remote 812 ADSL Router: seems to confuse maximum allowed UDP packet size with maximum size of entire IP packet, and sends packets which are 28 bytes too large. Seednet (ISP) VDSL: sends packets 2 bytes too large. config BUSYBOX_CONFIG_FEATURE_UDHCP_RFC3397 bool "Support RFC 3397 domain search options" default BUSYBOX_DEFAULT_FEATURE_UDHCP_RFC3397 depends on BUSYBOX_CONFIG_UDHCPD || BUSYBOX_CONFIG_UDHCPC help If selected, both client and server will support passing of domain search lists via option 119, specified in RFC 3397, and SIP servers option 120, specified in RFC 3361. config BUSYBOX_CONFIG_FEATURE_UDHCP_8021Q bool "Support 802.1Q VLAN parameters options" default BUSYBOX_DEFAULT_FEATURE_UDHCP_8021Q depends on BUSYBOX_CONFIG_UDHCPD || BUSYBOX_CONFIG_UDHCPC help If selected, both client and server will support passing of VLAN ID and priority via options 132 and 133 as per 802.1Q.
