OK cool thank you!

What if I want to see any data passing over that port, 113 or any other 
port? Any adjustments in this code?
SSH port 22 seems to work, well sort of.  When connections come in, 
shouldn't I see some type of encryption strings?

env ruby -w
require 'socket'
host = 'localhost'
port = 22
#
s = TCPSocket.open(host, port)

while line = s.gets   # Read lines from the socket
  puts line.chop      # And print with platform line terminator
end
s.close               # Close the socket when done
