Linux nodes instead of BPQ32 nodes in the LAN

[Miroslav Skoric <skoric@xxxxxxxx>]

Hi all!

I have been experimenting with 3 computers as AX.25 nodes in a home LAN,
as follows:

            _____________      ___________________   __________________
VHF        |MS DOS 5 comp|    |MS Windows XP comp|  |MS Windows XP comp|
TRX--TNC2--|  BPQ 4.09d  | -- |    BPQ32 4.10f   |--|    BPQ32 4.10f   |
ant         -------------      ------------------    ------------------

                (1)                   (2)                    (3)


In the situation above all 3 nodes talk to each other without problems.
What I wanted to do was to replace comps (2) and (3) with Linux nodes.
Both of those comps are dual-boot: (2) is Debian 6.0.1a, and (3) is
Ubuntu 10.04.2 LTS.

Ok so I installed libax, ax25tools and ax25apps, as well as node on both
(2) and (3) by using Synaptic but am not able to activate the nodes
properly. In fact, I have edited the main files in /etc/ax25 on both
machines according to the ancient AX.25-howto and then tried the
following commands in Ubuntu terminal (in Debian root terminal of course
without 'sudo'):

sudo modprobe bpqether (did not complain anything)
sudo /sbin/ifconfig bpq0 hw ax25 yt7mpb-15 up (did not complain either)
sudo ifconfig responded with:

sudo modprobe netrom (did not complain)
sudo nrattach netrom responded with:
NET/ROM port netrom bound to device nr0
sudo nrattach netnod responded with:
NET/ROM port netnod bound to device nr1
sudo ax25d responded with:
axconfig: port bpq0 not active
ax25d: no AX.25 port data configured
sudo netromd
axconfig: port bpq0 not active
netromd: no AX.25 ports defined

I suppose that I mis-configured and/or forgotten some important steps
and would like to contact somebody with more experience with Linux nodes
running over Ethernet. Btw, at the moment I do not plan to run any RF
ports on those Linux machines - just to have netrom nodes on them so
that those nodes should be able to talk with the dos computer (1), and
probably later I will add LinFBB to replace the WinFBB's that run over
BPQ32 nodes when (2) and (3) are booted as Win XP.
