Re: ax25ipd issue

[Bernard Pidoux <pidoux@ccr.jussieu.fr>]

Hi all,

Some hams using ROSE / FPAC packet switch through AXIP connexions faced 
this problem with non permanent IP stations.

We solved it by running a script every hour that calls host to resolve 
the ip address and append the route at the end of an original 
ax25ipd.conf without the no-ip route. Then this file is copied onto 
ax25ipd.conf.
Finally ax25ipd is killed and started again.
This solution works fine.

For those who are interested I put here an example of the script for one 
specific station.
Note : the two calls to ax25ipd at the end are intentional.

-----------beginning of the script ------------

#!/bin/bash
# Syntax: "majip.f5mtz.sh"
# by F4BVC, F1TE and F6BVP
#
/usr/bin/host f5mtz.no-ip.org > ip-f5mtz
export IP=`more ip-f5mtz | grep -w address | cut -b 29-`
cp /etc/ax25/ax25ipd_sav.conf /etc/ax25/ax25ipd.conf
if test "$IP" ; then
  echo "route F5MTZ-0 $IP udp 10093" >> /etc/ax25/ax25ipd.conf
fi
/usr/bin/killall -KILL ax25ipd
sleep 1
/usr/local/sbin/ax25ipd -l4
sleep 1
/usr/local/sbin/ax25ipd -l4
#

-----------------end of the script---------
