Check the docs on IO::Socket. Meantime here's a snip I played with to experiment with basic server listening...

#!/usr/bin/perl -w

use strict;
use IO::Select;
use IO::Socket;

my ($data, $fh);

my $ipc_select = IO::Select->new();

my $IPC_SOCKET = new IO::Socket::INET(Listen    => 5,
                                    LocalAddr => 'localhost',
                                    LocalPort => 9000,
                                    Proto   => "tcp" );

print "SOCKET = $IPC_SOCKET\n";

$ipc_select->add($IPC_SOCKET);
print "Listening...\n";
while (1) {
    if (my @ready = $ipc_select->can_read(.01)) {
        foreach $fh (@ready) {
            if($fh == $IPC_SOCKET) {
                #add incoming socket to select
                my $new = $IPC_SOCKET->accept;
                $ipc_select->add($new);
                print "incoming connection...\n";
            } else {
                # Process socket
                if (recv $fh,$data,1024,0) {
                    print $fh $data;
                    print "$data";
                } else {
                    $ipc_select->remove($fh);
                    $fh->close;
                }
            }
        }
    }
}

You can run this script, and then telnet in on port 9000 (or whatever other port you set it to listen on in 'localport') and it will echo your typing...
