I got mail to work but not the Usenet part. I connected to the server
for datemas.de and a list of groups they carry came down. But as soon
as I type in the search window, the list in the window below
vanishishes. Therefore I can't subscribe to any newsgroups I know they
carry. How can I subscribe to any newsgroups when the list vanishes?
Are you absolutely sure you've ticked "Always Request Authentication"
for your datamas.de setup ? It sounds like authentication is failing.
On Eternal-September, if you don't authenticate, the newsgroup list
only contains a small number of entries, like perhaps a dozen or
so. A very short list, hopefully including eternal-september.support.
By allowing posting to the support group, a user with authentication
failure issues, can talk to the operator of the system.
If on E-S, authentication with username and password is successful,
then the returned group list has thousands of entries. After
those thousands of entries are downloaded, they should be cached
in hostinfo.dat . By storing them there, that avoids annoying the
operator of that server, by fetching the list each time TB starts.
You can request TB to update the list of newsgroups, but that
should be done on an infrequent basis (because it wastes
server bandwidth).
To debug USENET issues, I use a copy of Wireshark, while the
news reader software is trying to connect. If I connect to
port 119, everything is in plaintext. I can see
Request: AUTHINFO user <accountname>
Response: 381 Enter password
Request: AUTHINFO pass <mypassword>
Response: 281 Authentication succeeded
USENET servers use numbered messages for their message strings.
Whether they are "errors" or simply "responses", a number appears
in front of the string. And I can see this in the trace window
of Wireshark. Wireshark samples transmitted and received packets
on my Ethernet interface leading to my router.
This trace, shows a session with a web server and web browser,
so you'll have to imagine how it would look with
"281 Authentication succeeded" on the right hand side.

With port 119, everything is in plaintext. With some of the
other port choices, communications would be encrypted, so
you can't check the username and password values as they
fly out of your computer.
