udhcp client not working

[satpal parmar]

Hi all;

   I am trying to make udchpc (UDHCP clinet from busybox) work on my kernel
(linux 2.6.11.12, linux 2.6.18 and linux 2.6.19 ).
 poted on arm9 board.I am getting following output


/ # udhcpc
udhcpc (v1.2.0-svn) started

I have a linux machine which works as dhcp server at ip adress
192.168.0.1and I am able to concet to another windows machine with
adress
192.168.0.20

Tcpdump on linux machine reflect no packet received from board.

my dmesg log:

I would also like to know what configuration in networking are MUST for dhcp
clinet to work.

Thanks in advance.
