Hey all, while running Good Vibes Radio, it became necessary to know the number of listeners on the server. You can use this sub to make a program that rings a bell (though good luck getting the Shoutcast plugin to broadcast it), or display it in a webpage, such as at Good Vibes Cafe. It comes in handy. Just call the sub listeners with the port. You can also of course keep track of total listeners if you have several servers on different ports. Have fun. This works with the Shoutcast server. It assumes you have it on the localmachine i.e. localhost, modify as needed. 

use strict;
use Net::HTTP;

sub listeners
{
my $port=shift;
#print "Initializing port $port\n";
my $http=Net::HTTP->new(Host=>"localhost",PeerPort=>$port);
$http->write_request('GET'=>'/7.html', 'User-Agent'=>'Mozilla/5.0');
#print "Reading in the HTML.\n";
my ($code,$mess,%h)=$http->read_response_headers;
my $buff;
my $n=$http->read_entity_body($buff,1024);
die "Cannot read the buffer. $!" unless defined $n;
my ($line) = $buff =~ /<body>(.+)<\/body>/;
my @sc=split(/,/,$line);
return $sc[0];
}
