I have two PERL programs that I am attempting to connect via sockets. The code below works fine when I attempt to connect to the socket on the same machine i.e. localhost.

Program: socketopen

use warnings;
use IO::Socket;

my $sock = new IO::Socket::INET (
                  LocalHost => 'localhost',
                  LocalPort => '12345',
                  Proto => 'tcp',
                  Listen => 1,
                  ReuseAddr => 1,
                );
die "Could not create socket : $!\n" unless $sock;
print "Socket created: $sock\n";

my $newsock = $sock->accept();

while (<$newsock>) {
print $_;
}
close($sock);

Program: socketconnect

use warnings;
use IO::Socket;

my $sock = new IO::Socket::INET (
                  PeerAddr => '192.168.x.xx',
                  PeerPort => '12345',
                  Proto => 'tcp',
                  
                );
die "Could not create socket : $!\n" unless $sock;

print $sock "Hello there!\n";
close($sock);

As soon as move one program to another machine I get: "Could not create socket : Connection refused"

Both machines are running Ubuntu. I know that the port is in a listening state from the output of netstat -tlp. And the Ubuntu firewall is inactive on both machines.

Any help and nudges in the right direction will be greatly appreciated.
