Step one completes successfully and I am also able see the
OFFER packets from the DHCP servers in ethereal,
But while reading on the socket, which I used for sending DISCOVER
PACKET I am getting resource unavailable error
and read fails.
Mac OS X already has a DHCP client bound to the corresponding UDP
receive port, so you can't bind to that endpoint. I've written a DHCP
Test tool that does something similar using the UNIX packet capture
library libpcap to read DHCP server responses.
