When creating connections to servers, how can I use a particular interface to make the outgoing connection?
I currently create connections with the following code:
IO::Socket::INET->new( PeerAddr => $Remote, PeerPort => $Port, Proto = +> 'tcp' );
All pointers in the right direction appreciated.

You can use IO::Socket::INET's LocalAddr property to force the packets out a specific interface.

use IO::Scoket; $socket= new IO::Socket( LocalAddr=>$host, LocalPort=>$port, ..... #other arguments ) or die "socket not created\n";
the $host is the IP of the interface you want and the $port is the port number you want the service to run....
