I'm trying to learn socket programming just for the heck of it, but there are a few things I'm just not seeing. In the following script, I'm trying to log the commands issued (via telnet) to this server. It creates the logfile, but it's always empty. Also, it does not process the if ($_ eq "quit") {} block correctly. Thanks in advance for any tips. 
#!/usr/bin/perl -w

use strict;
use IO::Socket;

my $host = 'localhost';
my $port = 9000;
my $client;

my $listen = new IO::Socket::INET->new( Proto => 'tcp',
                                        LocalPort => $port,
                                        Reuse => 1,
                                        Listen => 5, )
   or die "Can't start server";

while ($client = $listen->accept()) {
    open OUT, ">>/home/john/perl/daemonlog" or die "Can't open OUT: $!
+\n";
    while (<$client>) {
        chomp;
        print $client "Thank you for your command: $_\n";
        print OUT $_;
        if ($_ eq "quit") {
            close OUT;
            close $client;
        }
    }
}
close $listen;
