6 | config APP_UDHCPD |
7 | bool "udhcp server (udhcpd)" |
8 | default n |
9 | help |
10 | udhcpd is a DHCP server geared primarily toward embedded systems, |
11 | while striving to be fully functional and RFC compliant. |
12 | |
13 | config APP_DHCPRELAY |
14 | bool "dhcprelay" |
15 | default n |
16 | depends on APP_UDHCPD |
17 | help |
18 | dhcprelay listens for dhcp requests on one or more interfaces |
19 | and forwards these requests to a different interface or dhcp |
20 | server. |
21 | |
22 | config APP_DUMPLEASES |
23 | bool "Lease display utility (dumpleases)" |
24 | default n |
25 | depends on APP_UDHCPD |
26 | help |
27 | dumpleases displays the leases written out by the udhcpd server. |
28 | Lease times are stored in the file by time remaining in lease, or |
29 | by the absolute time that it expires in seconds from epoch. |
30 | |
31 | config FEATURE_UDHCPD_WRITE_LEASES_EARLY |
32 | bool "Rewrite the lease file at every new acknowledge" |
33 | default n |
34 | depends on APP_UDHCPD |
35 | help |
36 | If selected, udhcpd will write a new file with leases every |
37 | time a new lease has been accepted, thus eliminating the need |
38 | to send SIGUSR1 for the initial writing or updating. Any timed |
39 | rewriting remains undisturbed |
40 | |
41 | config DHCPD_LEASES_FILE |
42 | string "Absolute path to lease file" |
43 | default "/var/lib/misc/udhcpd.leases" |
44 | depends on APP_UDHCPD |
45 | help |
46 | udhcpd stores addresses in a lease file. This is the absolute path |
47 | of the file. Normally it is safe to leave it untouched. |
48 | |
49 | config APP_UDHCPC |
50 | bool "udhcp client (udhcpc)" |
51 | default n |
52 | help |
53 | udhcpc is a DHCP client geared primarily toward embedded systems, |
54 | while striving to be fully functional and RFC compliant. |
55 | |
56 | The udhcp client negotiates a lease with the DHCP server and |
57 | runs a script when a lease is obtained or lost. |
58 | |
59 | config FEATURE_UDHCPC_ARPING |
60 | bool "Verify that the offered address is free, using ARP ping" |
61 | default y |
62 | depends on APP_UDHCPC |
63 | help |
64 | If selected, udhcpc will send ARP probes and make sure |
65 | the offered address is really not in use by anyone. The client |
66 | will DHCPDECLINE the offer if the address is in use, |
67 | and restart the discover process. |
68 | |
69 | config FEATURE_UDHCP_PORT |
70 | bool "Enable '-P port' option for udhcpd and udhcpc" |
71 | default n |
72 | depends on APP_UDHCPD || APP_UDHCPC |
73 | help |
74 | At the cost of ~300 bytes, enables -P port option. |
75 | This feature is typically not needed. |
76 | |
77 | config UDHCP_DEBUG |
78 | bool "Compile udhcp with noisy debugging messages" |
79 | default n |
80 | depends on APP_UDHCPD || APP_UDHCPC |
81 | help |
82 | If selected, udhcpd will output extra debugging output. |
83 | |
84 | config FEATURE_UDHCP_RFC3397 |
85 | bool "Support for RFC3397 domain search (experimental)" |
86 | default n |
87 | depends on APP_UDHCPD || APP_UDHCPC |
88 | help |
89 | If selected, both client and server will support passing of domain |
90 | search lists via option 119, specified in RFC3397. |
91 | |
92 | config UDHCPC_DEFAULT_SCRIPT |
93 | string "Absolute path to config script" |
94 | default "/usr/share/udhcpc/default.script" |
95 | depends on APP_UDHCPC |
96 | help |
97 | This script is called after udhcpc receives an answer. See |
98 | examples/udhcp for a working example. Normally it is safe |
99 | to leave this untouched. |
100 | |
101 | config UDHCPC_SLACK_FOR_BUGGY_SERVERS |
102 | int "DHCP options slack buffer size" |
103 | default 80 |
104 | range 0 924 |
105 | depends on APP_UDHCPD || APP_UDHCPC |
106 | help |
107 | Some buggy DHCP servers send DHCP offer packets with option |
108 | field larger than we expect (which might also be considered a |
109 | buffer overflow attempt). These packets are normally discarded. |
110 | If circumstances beyond your control force you to support such |
111 | servers, this may help. The upper limit (924) makes dhcpc accept |
112 | even 1500 byte packets (maximum-sized ethernet packets). |
113 | |
114 | This option does not make dhcp[cd] emit non-standard |
115 | sized packets. |
116 | |
117 | Known buggy DHCP servers: |
118 | 3Com OfficeConnect Remote 812 ADSL Router: |
119 | seems to confuse maximum allowed UDP packet size with |
120 | maximum size of entire IP packet, and sends packets which are |
121 | 28 bytes too large. |
122 | Seednet (ISP) VDSL: sends packets 2 bytes too large. |
