             1. how to debug that code using a DDD de*.also can
any one hepl me to understand  the source code of it and its working
method of dhcp client.
             2. Please tell me how my dhcp discover packet is send
initally to a broad cast address.

             3. Please tell me how my dhcp discover message is
enclosed and send throug the network. how does it is really sent.

             4. Any one please reply to my questions in detail.

If you have to ask these questions, DON'T!

Please read the RFC 2131 and associated RFC's to get
the protocol details.

Fire up an Ethernet sniffer, e.g. tcpdump or Ethereal
and look at the packet exchange before attempting any
code debug.

There is a known problem of wrong source address in
pump (at least the older versions). If you're trying
to use pump, try dhcpcd or dhcpcd3 first before attempting
to debug. (The pump error is to bind UDP to port 0.0.0.0
instead of using a raw socket).
