I'm having some trouble getting my first foray into socket programming to work. This, I expect should open a socket on host 'foo' port 1880. This seems to work except, when I do a 'netstat -a' I don't see an entry for port 1880 which I expect to see listening. Here is the code:

#!/usr/bin/perl -w

use strict;
use IO::Socket;
my $new_sock;
my $buf;

my $sock = new IO::Socket::INET (LocalHost => 'foo',
                                 localPort => 1880,
                                 Proto     => 'tcp',
                                 Listen    => 5,
                                 Reuse     => 1
                                );
die "Unable to create socket: $!" unless $sock;
print "Waiting for message...\n";
while ($new_sock = $sock->accept()) {
    print $buf while (defined ($buf = <$new_sock>))        
}
close ($sock);

Further more when I try the folowing code on another machine I get a 'Connection refused' error:

#!/usr/bin/perl -w
use strict;

use IO::Socket;
my $sock = new IO::Socket::INET (PeerAddr => 'foo',
                                 PeerPort => 1880,
                                 Proto    => 'tcp'
                                );
die "Could not create socket: $!\n" unless $sock;

while (1) {
    print "Enter message: ";
    chomp (my $msg = <STDIN>);
    print "Sending $msg\n";
    print $sock "$msg\n";
    $sock->flush;
}
close ($sock)

These examples come from Advanced Perl, So I suspect they are correct.
Any suggestions will be greatly appreciated!

Update:
The server code is running on a windows nt4 machine while the client is an HPUX 11.x box

UPDATE:
I've got it working!

I noticed that while setting up the $sock object I did

my $sock = new IO::Socket::INET (LocalHost => 'sgilbertdt',
                                 localPort => 1200,
                                 Proto     => 'tcp',
                                 Listen    => 5,
                                 Reuse     => 1
                                );

The localHost shouldbe LocalHost.

As soon as I made the change and ran the script again, it showed up in netstat and I was able to pass the message from my Unix client.

Spelling Counts

Thanks Everyone

TIA
