Re: Using ax25ipd

[Christoph Rückert <christoph.rueckert@xxxxxxxx>]

Hello,

well I'm using the ax25ipd-software from <http://www.linux-ax25.org/wiki/CVS>.
You can create a connection between kernel and ax25ipd by bpq-pipe:

change device-line in /etc/ax25/ax25ipd.conf:
device axipd

no changes in /etc/ax25/axports.

create startscript /etc/init.d/ax25:
#!/bin/sh
AXPORT=axudp
BPQPIPE=axipd
ARP_CALL=AD7UF-12
IP_ADRESS=192.168.2.220/24      # you can also use an official 44er ip-address

case "$1" in
    start)
       # loading kernel drivers
       modprobe ax25
       modprobe bpqether

       # create bpq-pipe and axudp-device
       /usr/sbin/ax25ipd -c /etc/ax25/ax25ipd.conf
       sleep 3
       if [ -f /proc/net/bpqether ]
       then
           PORT=$(cat /proc/net/bpqether | grep $BPQPIPE | head -c4)
       else
           echo "Cannot create BPQ-Pipe, Abort!"
           exit 1
       fi

       #configure BPQ-kernel-device

       /sbin/ifconfig $PORT hw ax25 $ARP_CALL $IP_ADRESS mtu 1296 up

       ;;
    stop)

        killall ax25ipd
        sleep 5
        rmmod bpqether

        ;;
esac
exit 0

The kernel-device "axudp" was created. You can test the device by "call"-
program: call -s ad7uf axudp ke7awr
