Yes, yes, here I must apologize. I took listen only as an example

for monitoring your local QRG for who is QRV.
I _didn't_ want to start a listen on some remote server. This

You obviously have the entry 'radio' in your /etc/ax25/axports file as

erminal program UID root:
On the socket listens a daemon with UID root that could be started
upon system boot or with sudo or something else to assure its root
permissions. The terminal then must be able to talk to this daemon
to get information about the actual traffic on the QRG.
Is this a suitable approach or do I miss something here?

That's one of the neat SuSE secrets. In some cases, it decides

That's no pointless complaint, no, several people experienced
exactly that behaviour when installing SuSE. It seems to be version-
