I wrote this to get some exposure with sockets, and it turned out to have some value as a regex's exercise too. I don't know if anyone else will find this useful, but for me, its a cool use for perl! 
#!/usr/bin/perl

use strict;
use Socket;

my $check = 0;
my $port = 7000;
my $host = "divisionbyzero.net";

my @who, $line;

socket(TALKER,PF_INET,SOCK_STREAM,getprotobyname('tcp'));
connect(TALKER,sockaddr_in($port,inet_aton($host)));

 select(TALKER);
 $| = 1;

select('stdout');

sleep 1;
print TALKER "who\n";
while(<TALKER>)
{
 if(m/\+-{1,80}\+/) { $check++; }
 if($check)
 {
  push @who, $_;
 }
 last if ($check > 2);
}
print TALKER "quit\n";

close TALKER;

print "Content-type: text/html\n\n";

print <<  "end_header";


<html>
<head>
 <title>Who's on Ancient Realms II</title>
</head>
<body bgcolor=black text=white link=green vlink=green alink=purple>
<center>
<h3>Users Currently logged on:</h3>
end_header

foreach $line (@who) {
 chomp $line;
 $line =~ s/\e\[0m*//g;
 $line =~ s/^\s+//;
 $line =~ s/\s+$//;
 $line =~ s/ /\&nbsp;/g;
 print "$line <br>\n";
}

print "</center></body></html>";

exit 0;
