Hi everyone,
We are students at the University of Kansas trying to setup tcp/ip
over ax25 between two linux (Debian) boxes.

Each box is connected to a 2m radio (144.42 MHz) and a 1200 bps tnc.
they are in the same room.

Both linux boxes have ax.25 appls, tools and libraries installed and
have the kernel appropriately configured. We use the kissattach
command to create kiss network (ax0) interfaces and are trying to
establish the TCP/IP network between them.

While, ping works (around 50% loss), ssh (axssh client) is not
working. It just hangs. We were wondering if the high packet loss is
causing this.

We would appreciate if someone with more experience in using SSH over
AX.25 could help us out.

Thanks in advance,
Sriram

Have you tried adjusting txdelay and possibly txtail (using kissparms)?

The default ping interval is one second. You may need to increase this
(ping -i 2).

Do ftp and smtp also have problems?

I haven't tried SSH over AX.25, but, but at one time it was pretty
clear that it was not permitted by Part 97, because it obscured the
meaning of a transmission. There were some extensive revisions to the
rules a few years ago and this may have changed.
