# DO NOT EDIT. This file is generated from Config.src # # For a description of the syntax of this configuration file, # see scripts/kbuild/config-language.txt. # config UDHCPD bool "udhcp server (udhcpd)" default y depends on PLATFORM_LINUX help udhcpd is a DHCP server geared primarily toward embedded systems, while striving to be fully functional and RFC compliant. config DHCPRELAY bool "dhcprelay" default y depends on UDHCPD help dhcprelay listens for dhcp requests on one or more interfaces and forwards these requests to a different interface or dhcp server. config DUMPLEASES bool "Lease display utility (dumpleases)" default y depends on UDHCPD help dumpleases displays the leases written out by the udhcpd server. 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 FEATURE_UDHCPD_WRITE_LEASES_EARLY bool "Rewrite the lease file at every new acknowledge" default y depends on 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 DHCPD_LEASES_FILE string "Absolute path to lease file" default "/var/lib/misc/udhcpd.leases" depends on 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 UDHCPC bool "udhcp client (udhcpc)" default y depends on PLATFORM_LINUX 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 FEATURE_UDHCPC_ARPING bool "Verify that the offered address is free, using ARP ping" default y depends on 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 FEATURE_UDHCP_PORT bool "Enable '-P port' option for udhcpd and udhcpc" default y depends on UDHCPD || UDHCPC help At the cost of ~300 bytes, enables -P port option. This feature is typically not needed. config UDHCP_DEBUG int "Maximum verbosity level for udhcp applets (0..9)" default 9 range 0 9 depends on UDHCPD || UDHCPC || 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 FEATURE_UDHCP_RFC3397 bool "Support for RFC3397 domain search (experimental)" default y depends on UDHCPD || 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 UDHCPC_DEFAULT_SCRIPT string "Absolute path to config script" default "/usr/share/udhcpc/default.script" depends on UDHCPC 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. config UDHCPC_SLACK_FOR_BUGGY_SERVERS int "DHCP options slack buffer size" default 80 range 0 924 depends on UDHCPD || 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 dhcpc accept even 1500 byte packets (maximum-sized ethernet packets). This option does not make dhcp[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.
