- in /home/archive.nrao.edu/bin/ngams_socketclient.py sends command line to :

HOST = 'aocngas-master.aoc.nrao.edu'    # The remote host
PORT = 50007              # The same port as used by the server

- on HOST, python /home/archive.nrao.edu/bin/ngams_socketserver.py, executes cmd string recieved from the client.
