This is server program

use IO::Socket;
use Tk;

$| = 1;

$socket = new IO::Socket::INET (
                LocalHost => '10.101.3.55',
                LocalPort => '5000',
                Proto => 'tcp',
                Listen => 5,
                Reuse => 1
                );
die "Coudn't open socket" unless $socket;
print "\nTCPServer Waiting for client on port 5000";
while(1)
{
    $client_socket = "";
    $client_socket = $socket->accept();
    $peer_address = $client_socket->peerhost();
    $peer_port = $client_socket->peerport();
    print "\n I got a connection from ( $peer_address , $peer_port ) "
+;
    my ($txt,$mw,$frm_name,$lab,$ent,$txt,$but);
    $mw= MainWindow->new();
        while(1){
        #$mw->messageBox(-message=>"TCPServer Waiting for client on po
+rt 5000");
        $frm_name = $mw -> Frame() -> pack();
        $lab = $frm_name -> Label(-text=>"Name:") -> pack();
        $ent = $frm_name -> Entry() -> pack();
        $txt = $mw -> Text(-width=>40, -height=>10) -> pack();
        $but = $mw -> Button(-text=>"Push Me", -command =>sub {
            while (1)
            {
            # print "\n SEND( TYPE q or Q to Quit):";
            my $send_data =  $ent -> get();
            chop($send_data); 
            if ($send_data eq 'q' or $send_data eq 'Q')
            {
            $client_socket->send ($send_data);
            close $client_socket;
            last;
            }
            else
            {
            $client_socket->send($send_data);
            }
            $client_socket->recv($recieved_data,1024);
            if ( $recieved_data eq 'q' or $recieved_data eq 'Q')
            {
            close $client_socket;
            last;
            }
            else

This is my client program


#!/usr/bin/perl
use IO::Socket;
use Tk;



$socket = new IO::Socket::INET (
                                  PeerAddr  => '10.101.3.55',
                                  PeerPort  =>  5000,
                                  Proto => 'tcp',
                               )                
or die "Couldn't connect to Server\n";
die "Could not connect: $!" unless $socket;
my ($txt,$mw,$frm_name,$lab,$ent,$txt,$but);
$mw= MainWindow->new();
while (1)
{
    #print "hi\n";
    $socket->recv($recv_data,1024);
    
    if ($recv_data eq 'q' or $recv_data eq 'Q')
    {
        close $socket;
        last;
    }
else

        $frm_name = $mw -> Frame() -> pack();
