+config APP_UDHCPD
+ bool "udhcp Server (udhcpd)"
+ default n
+ help
+ uDHCPd is a DHCP server geared primarily toward embedded systems,
+ while striving to be fully functional and RFC compliant.
+
+ See http://udhcp.busybox.net for further details.
+
+config APP_DHCPRELAY
+ bool "dhcprelay"
+ default n
+ depends on APP_UDHCPD
+ help
+ dhcprelay listens for dhcp requests on one or more interfaces
+ and forwards these requests to a different interface or dhcp
+ server.
+
+config APP_DUMPLEASES
+ bool "Lease display utility (dumpleases)"
+ default n
+ depends on APP_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.
+
+ See http://udhcp.busybox.net for further details.
+
+config FEATURE_UDHCPD_WRITE_LEASES_EARLY
+ bool "Rewrite the lease file at every new acknowledge"
+ default n
+ depends on APP_UDHCPD
+ help
+ If selected, udhcpd will write a new file with leases every
+ time a new lease has been accepted, thus eleminating 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 APP_UDHCPD
+ help
+ The udhcpd stores address in lease files. Normaly it is save
+ to leave it untouched.
+
+
+config APP_UDHCPC
+ bool "udhcp Client (udhcpc)"
+ default n
+ 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
+ notifies a set of scripts when a lease is obtained or lost.
+
+ See http://udhcp.busybox.net for further details.
+
+config FEATURE_UDHCPC_ARPING
+ bool "Ask udhcpc to verify that the offered address is free, using arpping"
+ default y
+ depends on APP_UDHCPC
+ help
+ If selected, udhcpc will use arpping to make sure the offered address
+ is really available. 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 n
+ depends on APP_UDHCPD || APP_UDHCPC
+ help
+ At the cost of ~300 bytes, enables -P port option.
+ This feature is typically not needed.
+
+config FEATURE_UDHCP_DEBUG
+ bool "Compile udhcp with noisy debugging messages"
+ default n
+ depends on APP_UDHCPD || APP_UDHCPC
+ help
+ If selected, udhcpd will output extra debugging output. If using
+ this option, compile uDHCP with "-g", and do not fork the daemon to
+ the background.
+
+ See http://udhcp.busybox.net for further details.
+
+config FEATURE_RFC3397
+ bool "Support for RFC3397 domain search (experimental)"
+ default n
+ depends on APP_UDHCPD || APP_UDHCPC
+ help
+ If selected, both client and server will support passing of domain
+ search lists via option 119, specified in RFC3397.
+
+config DHCPC_DEFAULT_SCRIPT
+ string "Absolute path to config script"
+ default "/usr/share/udhcpc/default.script"
+ depends on APP_UDHCPC
+ help
+ This script is called after udhcpc receives and answer. See
+ examples/udhcp for a working example. Normaly it is save
+ to leave this untouched.

+config UDHCPC_SLACK_FOR_BUGGY_SERVERS
+ int "DHCP options slack buffer size"
+ default 80
+ range 0 924
+ depends on APP_UDHCPD || APP_UDHCPC
+ help
+ Some buggy DHCP servers will 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 options 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 big.
