+config 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.
+
+config DHCPRELAY
+ bool "dhcprelay"
+ default n
+ 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 n
+ 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 n
+ 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 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
+ 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 n
+ 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 0
+ range 0 9
+ depends on UDHCPD || UDHCPC || DHCPRELAY
+ help
+ Verbosity can be increased with multiple -v options.
+ This options 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 n
+ 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.
