When you have more specific questions, and have researched this a
little and can show what you have tried so far, post back and I'm sure
folks will help you.

First find out how to do it in C using the Unix sockets API. Suggested
resource is "Unix Network Programming volume 1" by Richard Stevens, pub
Addison Wesley. Or you can find existing code which sends raw packets
and reverse-engineer that. Ask questions on a kernel/networking mailing
list if you have problems.

Once you know this, you can translate easily to Ruby, since ruby's
Socket is a thin layer on top of this.

Google "ruby socket" and the first hit is the socket documentation. Also
look in the sockets documentation at
http://www.ruby-doc.org/books/ProgrammingRuby (click on "Network and Web
Libraries")

Follow the link in my sig and you'll find some presentations bursting
with code for UDP and TCP network comms. These aren't raw packets in
the fullest sense of the term but depending on your intent they may
suffice.
