my code is like this 
#!/usr/bin/perl

use strict;
use Chatbot::Eliza;
use IO::Socket;
use POSIX 'WNOHANG';

use constant PORT => 12000;

my $quit = 0;

#singal handler for child die events
$SIG{CHLD} = sub { while ( waitpid(-1, WNOHANG)>0) {}};
$SIG{INT} = sub {$quit++};

my $listen_socket = IO::Socket::INET->new(LocalPort => PORT,
                                          Listen => 20,
                                          Proto=> 'tcp',
                                          Reuse => 1,
                                          Timeout => 60*60,
                                        );
die "cant create a listening socket : $@" unless $listen_socket;
warn "Server ready . waiting for connections ...\n ";

while(!$quit)
{
next unless my $connection = $listen_socket->accept;

defined (my $child = fork()) or die " cant fork : $!";
if ($child == 0)
{
$listen_socket->close;
interact($connection);
exit 0;
}
$connection->close ;
}

sub interact {
my $sock = shift ;
STDIN->fdopen($sock,"<") or die " cant reopen STDIN: $!";
STDOUT->fdopen($sock,">") or die "cant reopen STDOUT: $!";
STDERR->fdopen($sock,">") or die "cant reopen STDERR: $!";
$|=1;

my $bot = Chatbot::ELiza->new;
$bot->command_interface();
}
