Thanks for the explanation. I am not that familiar with the details in PYthon of setting up an RPC server. Looking around I see RPC things in the rpc.py program, evidently related to the file server features. If you have two clients communicating through a ratflector does the ratflector somehow use the 9100 port? I assume the test would be to transfer and delete some files.
Thanks again and 73, Richard Browning AD5RB
