Hi,
I realize that this is going to be a long mail, and is therefor boring
to read :^) But I hope you will make it to the nd of this mail and
hopefully have a solution for my problem.
For quite some time now we are havning problems with periodic
disconnects.
Until recently we had a PC equiped with a SCC card. But the SCC port for
the full duplex link with the neighboring node locked up several times
per day.
Last week we moved the PC to the same location as the node and connected
it via an ethernet axip link. We hoped that both the SCC port lock-up
and the periodic disconnects would disappear.
But the periodic disconnects still occur.
I'm not sure if the problem is with the FBB deamon, with the AX.25
utils, with the AX.25 protocol implementation in the kernel, or because
of a configuration error.
The symptoms are as follows. While retrieving data from the BBS (via
digipeater) and the link quality is good, the user suddenly receives a
D frame.
See trace below.

As you can see also other users get disconnected at the same time.
If I then reconnect to the BBS, and give the ! command, I see my call
sign in the list twice.
Apparently FBB thinks that I'm still connected.
Has anybody else experienced this and found the solution?
Is it a coniguration error?
If so, do you see anything wrong in the files below?
Thanks in advance.
