Cannot run filetransfer example #24

Closed PhilReinhold closed 4 years ago

PhilReinhold commented 4 years ago

I'm on windows/py3.7/Pyro5 v5.10

The filetransfer server fails with 

File "server.py", line 79, in __init__
host, _ = self.transportServer.sock.getsockname()
ValueError: too many values to unpack (expected 2)

It appears the socket is AF_INET6, so getsockname returns more stuff. Changing line 79 to host = self.transportServer.sock.getsockname()[0], the server runs. The client now fails with

The above exception was the direct cause of the following exception:

That permission error is something on your end, most likely your user hasn't got the correct privileges to access the network. What port are you running on? Less than 1024 is likely problematic (unless you have administrator privileges)

The suggested fix for the ipv6 address is sound and I've committed that.
