Re: how can I set LocalAddr to INADDR

Your whole problem rest on the claim that the source address must be '0.0.0.0'. Are you sure about that? It would normally be that since the machine has no other address, but I don't think it's a requirement.

For example, wouldn't the source address be something other than '0.0.0.0' in the case where the request is forwarded by a router? It's been a while since I've read the spec and it's not jumping out at me.

Thanks ikegami, you are right! I tried the script and the discovery packet with a non-zero SA packet can be recognized by the DHCP server, which means my assumption is wrong. Thank you all :-)	[reply]

Yes, I'm trying to simulate a DHCP client to communicate with the server. And normally, when I issue a DHCP discovery request, the Source IP Address should be 0.0.0.0, I haven't seen any discovery packet with a non-0.0.0.0 source address. So if I want to send out a DHCP discovery packet, the SA must be 0.0.0.0.	[reply]
