Hi Monks, i hope you are all right! This is my first question so please pardon me if it is execess newbie. I`m trying to code a client/server remote administrator with some functions like port knocking and etc.. but one special situation i have a problem. I make server connect to my client to avoid firewall configurations and it connects right but when i try to do my commands only the first one is executed, take a look: 
-----
# ./client.pl
Connection estabilished from:
Source IP-> 127.0.0.1
Source port-> 32894

command> uname
Linux

And then it is freeze. I know that server is ok becouse when i use netcat as client everythings goes nice, here is a piece of client`s code: 
sub listen() {
$local = IO::Socket::INET->new(Listen=>1,
                               Proto=>'tcp',
                               LocalAddr=>'eth0',
                               LocalPort=>5000,
                               ReuseAddr=>1,) or die "$!";
$local->autoflush(1);
$addr_handle = $local->accept();

$remotehost = $addr_handle->peerhost ;
$remoteport = $addr_handle->peerport ;
print "Connection estabilished from:\nSource IP-> $remotehost\nSource 
+port-> $remoteport\n";

print "command> ";
                while(defined ($comm = <STDIN>)) {
                        print $addr_handle $comm;
while(<$addr_handle>) {
                                print STDOUT $_
                        }
                        print "command> ";
                }
}
