Yes, LocalPort => '127.0.0.1' is a typo for LocalAddr => '127.0.0.1'. The latter means only accept connections from 127.0.0.1. (Actaully, it means listen for connections whose destination address is 127.0.0.1, which should mean the same thing.) I used that for testing.

while (defined($incoming = <$client_sock>)) can indeed be simplified to while ($incoming = <$client_sock>). Old habbit. It's not needed here, and it's not needed when doing while (defined($line = <$fh>)), where I picked up the habbit.

Yes, if (0) is just an easy way to comment out a section. I didn't have a header file.
