TCPSocket represents a TCP/IP client socket.
A simple client may look like:
require 'socket' s = TCPSocket.new 'localhost', 2000 while line = s.gets # Read lines from socket puts line # and print them end s.close # close socket when done

Opens a TCP connection to remote_host
on
remote_port
. If local_host
and
local_port
are specified, then those parameters are used on
the local end to establish the connection.
