If you have the entire packet in hex data, write a short program to parse the hex, stuff it into a datagram, and send it back out on a network interface, like a loopback or to a non-routable destination IP. Sniff the interface with tcpdump/Ethereal, and now you can get it parsed. You might be able to use netcat or netcat.pl to get the packet back out on the wire, which would simplify things. ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
