Any idea why this code...

require 'socket'
server = TCPServer.new('127.0.0.1', 5056)
socket = server.accept
socket.puts('it works')
socket.flush

doesn't work on my Unix server?  If I run it in the background, I can
connect from the same machine using telnet and it works fine... but I
cannot connect from any remote machines.

What am I missing?
