How can I obtain the ip address of the originating (client) socket ,  
in a server/client socket ruby program?

What ruby library is fitted with a class/ method to do this?  
How can it be done using ruby?

I would appreciate some sample code.

sock\_domain, remote\_port, remote\_hostname, remote\_ip = socket.peeraddr

# note: sock\_domain is the address family, e.g. “AF\_INET”
