I am trying to open a series of sockets (10) to receive some data. As soon as a new one is opened the previous one is closed with FIN / Fin ACK etc. Please tell me if this approach should work or what is wrong with it. Do I HAVE to Fork or thread etc.? This is my 1st. perl prog.

This is the code.

#!/usr/bin/perl -w

$IP_Addr = "ss6";
#$TCP_port = (1025);

print "Enter start TSG port: "; chomp ($TCP_port = <stdin>);
print "Enter last TSG port: "; chomp ($last_TSG = <stdin>);

use IO::Socket;

while ($TCP_port <= $last_TSG) {
        open_TSG ($IP_Addr, $TCP_port);
        $TCP_port +=1 ;
                             }



sub open_TSG {
#       use IO::Socket;
        $remote = IO::Socket::INET->new(
                        Proto => "tcp",
                        PeerAddr => $IP_Addr,
                        PeerPort => $TCP_port,

                )
        or die "Cannot conect to port $TCP_port at $IP_Addr";
        $response = <$remote>;
        print "$TCP_port active\n";
        print $remote "g\n";

             }



 while ( <$remote> ) {print  </dev/null> }
