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.

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.

If selected, udhcpc will use arpping to make sure the offered address

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.
