Yes, dnspython.

Well that's news to me! I will raise it with the proper authorities, 
although I don't know that it will make a difference. That is enough to 
make me question whether or not dnspython is fit for purpose any longer.

code should come back into fashion... my goal was to support LOTL to the 
extent possible.

Yes, I've run into permissions issues myself. My framestream server 
attempts to remove and re-create the socket with the proper owner / 
permissions.

Happy hunting...
