A basic client and server, socket implementation(untested).

Server:

use strict;
use IO::Socket;
my $sock = new IO::Socket::INET (LocalHost => 'localhost',
                             LocalPort => 5004,
                             Proto     => 'tcp',
                             Listen    => 5,
                             Reuse     => 1                           
+  
                            );
die "Socket could not be created. Reason: $!" unless $sock;
my ($new_sock, $buf);
while ($new_sock = $sock->accept()) 
{
   print "Connection from ", $new_sock->peerhost, ": on port ", $new_s
+ock->peerport,"\n";
   print $new_sock "Hello from the server";
   while (defined ($buf = <$new_sock>)) 
   {
      print $buf;
   }
}
close ($sock);

Client:

use strict;
use IO::Socket;
my $line;
my $socket = new IO::Socket::INET (
                               PeerAddr => 'localhost',
                               PeerPort => '5004',
                               Proto => 'tcp',
                               );
die "Could not create socket: $!\n" unless $socket;
$socket->recv($line, 80);
print "$line";
print $socket "Hello from the Client!\n";
close($socket);
