You need to give us more details on what the "simple" client and server program is doing for its connectivity, functionality, etc. We know nothing about it and without more information, we can only theorize about possibilities. If you give us more info (or even share the code), then maybe we can provide more definitive avenues for investigation. Also, knowing what OS's your attempting to run it on would also be helpful.

Are you getting errors like, "Could not open socket" from your client and server program? if yes, just use a 5 digit port.

The below code are my program

#Client program
#!/usr/bin/perl
use IO::Socket::INET;
use strict;
 
 
my $name = '24.221.34.34'; #Server IP
my $port = '78901';
 
my $socket = IO::Socket::INET->new('PeerAddr' => $name,
                                   'PeerPort' => $port,
                                'Proto' => 'tcp') or die "Can't create socket ($!)\n";
 
print "Client sending\n";
while (1) {
    my $msg = <STDIN>;
    print $socket $msg;
    print scalar <$socket>;
}
close $socket
    or die "Can't close socket ($!)\n";
#Server program 
 
 
#!/usr/bin/perl
use IO::Socket::INET;
use strict;
 
my $port = "78901";
 
my $socket = IO::Socket::INET->new('LocalPort' => $port,
                                   'Proto' => 'tcp',
                                   'Listen' => SOMAXCONN)
    or die "Can't create socket ($!)\n";
    print "Socket connection";
 
 
while (my $client = $socket->accept) {
    my $name = gethostbyaddr($client->peeraddr, AF_INET);
    my $port = $client->peerport;
    while (<$client>) {
        print "[$name $port] $_";
        my @out = `$_`;
        print @out;
        print $client "$.: @out";
    }
    close $client
        or die "Can't close ($!)\n";
}
 
die "Can't accept socket ($!)\n";
 

The client program have displayed below error
Can't create socket (No connection could be made because the target machine actvely refused it.)
please help me

First, you need to have the shebang line ( #!/usr/bin/perl) as the very first line in your script. If you put it anywhere BUT the first line, it is a comment and doesn't do anything.

Second, your issue, from reading the error, is on the second machine, which "actively refused it". I would start by troubleshooting why it refused the connection.

Another thing you can do is try printing "$!" as part of your die() function call as it prints the last error received.
