  14           udhcpd is a DHCP server geared primarily toward embedded systems,

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

  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.

  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

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

  58           udhcpc is a DHCP client geared primarily toward embedded systems,
  59           while striving to be fully functional and RFC compliant.
  60
  61           The udhcp client negotiates a lease with the DHCP server and
  62           runs a script when a lease is obtained or lost.

  69           If selected, udhcpc will send ARP probes and make sure
  70           the offered address is really not in use by anyone. The client
  71           will DHCPDECLINE the offer if the address is in use,
  72           and restart the discover process.

  88           Verbosity can be increased with multiple -v options.
  89           This options controls how high it can be cranked up.

  91           Bigger values result in bigger code. Levels above 1
  92           are very verbose and useful for debugging only.

 100           search lists via option 119, specified in RFC 3397,
 101           and SIP servers option 120, specified in RFC 3361.

 117         help
 118           Some buggy DHCP servers send DHCP offer packets with option
 119           field larger than we expect (which might also be considered a
 120           buffer overflow attempt). These packets are normally discarded.
 121           If circumstances beyond your control force you to support such
 122           servers, this may help. The upper limit (924) makes dhcpc accept
 123           even 1500 byte packets (maximum-sized ethernet packets).
 124
 125           This option does not make dhcp[cd] emit non-standard
 126           sized packets.
 127
 128           Known buggy DHCP servers:
 129           3Com OfficeConnect Remote 812 ADSL Router:
 130             seems to confuse maximum allowed UDP packet size with
 131             maximum size of entire IP packet, and sends packets which are
 132             28 bytes too large.
 133           Seednet (ISP) VDSL: sends packets 2 bytes too large.
