  14           udhcpd is a DHCP server geared primarily toward embedded systems,
  15           while striving to be fully functional and RFC compliant.

  22           dhcprelay listens for dhcp requests on one or more interfaces
  23           and forwards these requests to a different interface or dhcp
  24           server.

  31           dumpleases displays the leases written out by the udhcpd server.
  32           Lease times are stored in the file by time remaining in lease, or
  33           by the absolute time that it expires in seconds from epoch.

  35 config BUSYBOX_CONFIG_FEATURE_UDHCPD_WRITE_LEASES_EARLY

  38         depends on BUSYBOX_CONFIG_UDHCPD
  39         help
  40           If selected, udhcpd will write a new file with leases every
  41           time a new lease has been accepted, thus eliminating the need
  42           to send SIGUSR1 for the initial writing or updating. Any timed
  43           rewriting remains undisturbed.

  49         help
  50           If selected, udhcpd will base its selection of IP address to offer
  51           on the client's hardware address. Otherwise udhcpd uses the next
  52           consecutive free address.
  53
  54           This reduces the frequency of IP address changes for clients
  55           which let their lease expire, and makes consecutive DHCPOFFERS
  56           for the same client to (almost always) contain the same
  57           IP address.

  64           udhcpd stores addresses in a lease file. This is the absolute path
  65           of the file. Normally it is safe to leave it untouched.

  72           udhcpc is a DHCP client geared primarily toward embedded systems,
  73           while striving to be fully functional and RFC compliant.
  74
  75           The udhcp client negotiates a lease with the DHCP server and
  76           runs a script when a lease is obtained or lost.

  82         help
  83           If selected, udhcpc will send ARP probes and make sure
  84           the offered address is really not in use by anyone. The client
  85           will DHCPDECLINE the offer if the address is in use,
  86           and restart the discover process.

 102           Verbosity can be increased with multiple -v options.
 103           This option controls how high it can be cranked up.
 104
 105           Bigger values result in bigger code. Levels above 1
 106           are very verbose and useful for debugging only.

 130           This script is called after udhcpc receives an answer. See

 139         help
 140           Some buggy DHCP servers send DHCP offer packets with option
 141           field larger than we expect (which might also be considered a
 142           buffer overflow attempt). These packets are normally discarded.
 143           If circumstances beyond your control force you to support such
 144           servers, this may help. The upper limit (924) makes dhcpc accept
 145           even 1500 byte packets (maximum-sized ethernet packets).
 146
 147           This option does not make dhcp[cd] emit non-standard
 148           sized packets.
 149
 150           Known buggy DHCP servers:
 151           3Com OfficeConnect Remote 812 ADSL Router:
 152             seems to confuse maximum allowed UDP packet size with
 153             maximum size of entire IP packet, and sends packets which are
 154             28 bytes too large.
 155           Seednet (ISP) VDSL: sends packets 2 bytes too large.
