ONEWAY ONLY?
Packet-Connects can only be initiated from the outside into a Linux/ax25-PC.
All connects iniated from within the Linux/ax25-PC end prematurely and get
disc+ from inside.
Software: Suse 9.0, Kernel with AX25 (kisslink) via COM1, Application
DXSpider.
No nodesofware or what so ever on the machine.
1.. User und neighbor-DX-Clusters shall connect db0spc-7 via a
Packetswitch (RMNC) which is hardwired (kiss) to the Linux-PC.
2.. The Cluster-PC(Linux) db0spc-7 shall be able to call neighbor
clusternodes via the kisslink and the Packetswitch.
Task 1 functions perfectly. Users and clusternodes can initiate connects and
get a stabile and fast link. All works as expected.
We have some users and several clusternodes connected for many hours in a
row, without any problems. This is why I assume the hardware involved is Ok
and the ax25 configuration on the Linux machine can't be all wrong.
Task 2: When attempting to initiate a connects from within db0spc-7 you see
that the SABM is sent out via the kisslink. It gets to the TNC called. Then
the reply is received, all fast and as expected. Then after about 300ms the
QSO is cut off by a disc+ , sent by db0spc-7
All INCOMING CONNECTS are OK, ALL OUTGOING CONNECTS are terminated by the
Linux PC.
Tests:
The application software was killed to ensure the problem is not created by
DXSpider.
>From within a shell I do listen kiss -a and then monitor what traffic is
on the kisslink between the Linux PC and the Packetswitch.
>From within a second shell I start calling other stations which are
reachable by the Packetswitch. Or I simply try to connect the Packetswitch
itself.
Instantly there is a connect and the station called sends one or two frames.
However then the Linux-PC db0spc-7 ends it and sends a disc+
Whatever I try, there is a connect and about 300ms later the software on
the Linux PC (ax25)
kills the link.
I got in touch with other sysops who run similar setups. They have no
problems and Packet-QSOs can be initiated from both ends and without any
problems,
All my attempts to solve the problem by altering the ax25d.conf or the
kissport parameters did fail. The problem seems to hide somewhere else and I
can't find it.
The problem remains, INCOMING CONNECTS Ok, OUTGOING CONNECTS GET DISC BY
THE LINUX/ax25-PC.
What is causing all this and how can I get rid of these strange disconnects
by my own machine?
I did post my problem on some reflectors but all the good advice did not
produce any positive result. The real ax25-experts hide somewhere or just
do not answer
73, Klaus
Perhaps there is somebody out there who can interpret this trace and
pinpoint the problem zome?
