SSH over AX.25

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

Aside from anything else, is it actually legal to use encryption (which is
what ssh is) on amateur radio frequencies? Various governments have
differing thoughts on this and I'm not 100% up on the US license
conditions.

If you're getting that sort of packet loss you need to work out why and fix
it before you advance beyond basic link testing. You should be getting near
0% packet loss on a decent link.

As far as I know, encryption on the amateur radio bands, is illegal in
Canada, U.S. and other countries. This also creates an interesting
situation in 802.11b & g WiFi. In this situation, there is some overlap
between WiFi and an amateur radio band. This means that an amateur can run
far more power than others and on other frequencies, as allowed by his
licence. But by the terms of that same licence, encryption cannot be used.
So an amateur can either use standard WiFi & WEP or other encryption, just
like anyone else, or he can run more power and on other frequencies, but
without any encryption.
