It ain't perfect, but:

require 'socket'
port = 2200
server = nil
Timeout::timeout(2.0) do

client = TCPClient.new( 'localhost', port )

Of course. Still, I don't like this because what about well-secured
server machines with local firewall configurations that don't permit
this kind of swiss cheese? (Well, except for Windows servers, I guess-
anything that has to run Active Directory is hopeless in regard to
firewalls anyway.)
