newsreader connecting on port 563

[Anton Shterenlikht]

I've been happily using nn, connecting to aioe.org
on default port 119. Something happened, perhaps with
the university firewall, or something else. A colleague
tells me he can connect to aioe.org on port 563 using
some MS based newsreader.

I cannot see how to tell nn to connect on port 563.

Is there a way?

I also tried to slrn, which provides "-p port" option,
but still no luck:

$ slrn -p 563
slrn 1.0.2

Loading /usr/local/share/slrn/slang/slrn.sl
Using newsrc file /home/mexas/.jnewsrc for server aioe.org.
Connecting to host aioe.org ...
Failed to initialize server
Run-Time Error
Reason: 
slrn fatal error:
Failed to initialize server.


Please advise

Thanks

Anton
