annoying ax25ipd problem
Gavin Rogers
I'm having a problem with ax25ipd which I'm hoping someone can help me with.
A few of my AXUDP partners are on dial up links and their connections go
down every so often. I have scripts in place on my gateway to make sure
that the UDP packets destined for these people ends up in the right place.
The problem is, that the scripts are only run every few minutes and their
dyndns.org (etc) entries take time to update, so there are times where my
system does not know the correct IP for the AXUDP system.
In the mean time, the IP address that used to be allocated to that amateur
is taken by someone else. This tickles a bug in AX25ipd - if, while sending
AXUDP packets, the response is "connection refused", then ax25ipd will
crash completely. This, in turn, exposes a bug in FBB, which will crash as
it tries to open the now non-existent axip port.
I'm using ax25ipd version:
starbase:/etc# /usr/sbin/ax25ipd -v
ax25ipd Version 1.0.2 / 0.0.6

Apart from writing a hack script to ensure that ax25ipd is always running
(and restart it if it isn't), does anyone know how I can get around this
problem?
Many thanks.

Gavin Rogers
