kissattach and kernel 2.6

kissattach and kernel 2.6

[oz6bl]

Hi,

I'm the developper/maintainer of PB/PG for Linux but I havn't been active
for a while, in fact not since the kernel was 2.4.24 or something. Now I
try to get PB/PG up and running again under a 2.6 kernel but it appears
that quite a few things have chaned since then. Before even embarking on
PB/PG I try to bring the 'standard' AX.25 things up and running: listen,
call, etc, but I must admit with very little success.

What I have is this: My distribution is SUSE 9.2 with a 2.6.8 kernel. The
AX.25 tools are version 0.0.8 and the AX.25-apps are 0.0.6. My modem is a
DSP-12 in kiss mode attached to /dev/ttyS0. My PC has a Pentium 4 and I
normally run a SMP version, but since I learned that e.g. mkiss doesn't
work with SMP, I use a mono-CPU version ('default' in SUSE terms). I can
configue an ax0 interface with kissattach ('kissattach -l /dev/ttyS0 asy
44.145.40.3'), but I can't get listen to display any packets, in fact
'ifconfig' doesn't show any packets received. I have seen some patches
mentioned, but they appear to apply to mkiss in userland so I am really at
a loss as to what to do.

Could someone please help me with pointers and/or help?

I would suggest using the ax25 packages from CVS, there are some small
fixes for linux 2.6.x. Admitly, I've not done much to test it since I don't 
have a running packet station since my last move.

Hope that helps.

I have taken a look at the ax25 CVS repository on Sourgeforge
(http://cvs.sourceforge.net/viewcvs.py/ax25/), but it seems to be somewhat
old (3 to 4 years for the most part) and the newer files does not appear
to be related to the areas where I suspect the problem lies (the mkiss
kernel driver or the kissattach program). Is it this repository you were
thinking of?

This is probably not of much help...but AX.25 works perfectly with 
kernel 2.6.3-7mdk (Mandrake 10.0 Community), tested only with the 
serial full-duplex 1k2 baycom driver . It is rock-solid and goes for 
months. I should mention I don't use NET/ROM.

I am contemplating an upgrade to Debian 3.1 in a week or so...I guess 
I will find out whether AX.25 support is broken post- 2.6.3 ...

Hi everybody

and thanks for all the replies and advice. I have it working now! It turns
out that I had to use userspace mkiss. Most of the setups that were
presented to me included a call to mkiss but I had ignored it, because I
use a single port TNC (a DSP-12). When I tried the following, however, it
worked:

/usr/sbin/mkiss -s 115200 /dev/ttyS0 /dev/ptyq0
/usr/sbin/kissattach /dev/ttyq0 asy 44.145.40.3

so now I have listen and call etc up and running. I guess there is a
lesson to be learned from this but I'm not quite sure which...

BTW I'm using the versions of ax25-tools (0.0.8), ax25-apps (0.0.6) etc
that comes with SUSE 9.2, so the release versions are OK.
