Subject: AX.25 and Linux - my experience
To: ham-digital@ucsd.edu
Hi,
A few days ago I posted a question about AX.25 and Linux - various people asked
me to post my findings, so here goes. Please don't have a go at me re: my lack
of knowledge of the Linux kernel; although I've been Linuxing for quite a
while, my knowledge of the kernel is fairly limited.
This is how I got KISS encapsulated AX.25 TCP/IP working on Linux 0.99-pl15.
Note that some of this is conjecture; i.e. it seems to work :-)
1. ftp the AX.25 patches from sunacm.swan.ac.uk:/pub/misc/Linux/Radio/AX25012
(there may be a later revision than 12).
2. Unpack the new files in the Linux source tree - there are a few in net/inet,
and one in include/linux.
3. Do a 'mknod /dev/af_ax25 c 30 0' (I don't know if this is actually necessary).
4. Edit drivers/net/slip.c. Search for ax25_test, and change the callsign therein
to your own. For example, for my call (G7OMZ-5):
static char ax25_test[7]={'G'<<1,'7'<<1,'O'<<1,'M'<<1,'Z'<<1,' '<<1,'5'<<1};
5. The next bit is quite hacky. There is an implementation of KISS encapsulation
in slip.c, but by default it isn't enabled. I couldn't figure out how to make
a SIOCSIFENCAP ioctl() call (I didn't know what to give it as a file descriptor),
so I just hard-wired it to set all SLIP channels to SL_MODE_AX25 in
sl_initialize(). Of course, this won't do if you use SLIP for anything else,
so you'll have to hack around in slip_init(). There's a call to sl_initialize()
in there, so you'll have to test for certain interfaces and set SL_MODE_AX25
accordingly. I don't know enough about the kernel to comment.
6. Edit config.in, and search for CONFIG_PLIP. Add a line above it:
bool 'AX.25 (KISS) encapsulation support' CONFIG_AX25 y
7. make mrproper ; make config ; make dep ; make zImage, then install the new kernel
as per usual and reboot. Fingers crossed!
8. When the system comes back up, create a file containing the following commands:
port ttyS2
speed 9600
term
local 44.131.1.254
remote 44.131.1.57
mode SLIP
Replace ttyS2 with the port your TNC is connected to, and the local IP address
should be your own. The remote IP address should be either the nearest
neighbour through whom you want to route, or your local subnet (mine is
44.131.1.0).
9. Type 'dip filename'. You'll be in terminal mode with your TNC. Put it into
KISS mode (usually 'kiss on') and type a ^]. This should set everything up
for you.
10. If you type /etc/ifconfig, you should see two messages; one for the loopback
device 'lo', and one for 'sl0'. If you type /etc/route, you should see that
there is now an entry for 'sl0'. You can either make this your default
router (as you would do if there is an Internet gateway nearby) with:
/etc/route add default gw 44.131.1.57
...or (more likely) you will only want to route ampr.org packets through it,
which will look like:
/etc/route add 44.0.0.0 gw 44.131.1.57
11. That's it! You can now add those commands to your /conf/net/rc.inet[12]
files to set it up at boot time.
Cheers,
Ian.

The address is correct. Your system is not handling MX records properly, I
would guess. Ask your friendly system administrator. Using nslookup, set type
to MX, and try arrl.org. You should get a response showing you who handles
mail for arrl.org. Your mailer is supposed to automatically do this lookup
and push the mail along.

The unknown host is the reason fingering was no help. I should have this
added important point to my original post 8^(.
Our DNS server can't seem to make any sort of resolution about it either.
After setting the default server to NS.PSI.NET nslookup was able to come
up with the following, but no resolution for arrl.org!
****************************************************************************
Default Name Server: NS.PSI.NET
Address: 192.33.4.10
> arrl.org
Name Server: NS.PSI.NET
Address: 192.33.4.10
arrl.org
origin = ns.psi.net
mail addr = hostmaster.ns.psi.net
serial = 199311301
refresh = 7200 (2 hours)
retry = 900 (15 mins)
expire = 2592000 (30 days)
minimum ttl = 86400 (1 day)
arrl.org nameserver = ns.psi.net
arrl.org nameserver = ns2.psi.net
arrl.org preference = 5, mail exchanger = mgate.arrl.org
arrl.org preference = 10, mail exchanger = uu7.psi.com
ns.psi.net internet address = 192.33.4.10
ns2.psi.net internet address = 192.35.82.2
mgate.arrl.org internet address = 38.1.219.1
uu7.psi.com internet address = 38.145.204.6
****************************************************************************
I don't know what the problem is. Maybe a DNS guru can point something out?
I haven't yet tried to mail something so I don't know if this resolution
trouble is going to cause me grief now that I have the addresses for the
arrl.org folks.

That's because arrl.org is not a host, it's a mail address.
If you use nslookup like so:
nslookup -query=MX arrl.org
You'll find out all you need to know, including the fact that ARRL
mail is handled by hosts mgate.arrl.org and uu7.psi.com, in that
order of preference.
If your system is for some strange reason unable to deal with
standard mail addressing via DNS (i.e., MX records), you can
use @mgate.arrl.org instead. Presumably you system can resolve
that!

You missed where Tim was posting from, Grenoble FRANCE. He wasn't reading
from part 97 at all. He was reading from Part XYZZY of the French equivalent
of the FCC's rule book.
Thats the problem with the Internet. You can have a nice quiet little
conversation and not realize that your actually shouting around the world
if your not carefull about noticing where all the participants are standing.
;^)....The above wasn't a flame, just an observation. Since I work for
HP, Grenoble sticks out more to me.

Subject: Linux AX.25 driver
To: ham-digital@ucsd.edu
I installed the ax25 patch and compiled a pl15 kernel for my
machine. I tried both the pl15 kernel available on funet.fi
and the pl15h I found here at school. When I boot and try
to do an axattach, I get an error that looks something like:
SIOC(something,something): Invalid argument.
It's the same kind of error I get when it can't find the
ethernet card. I haven't installed the driver for my
ethernet card yet so I don't know if that will fix it.
Does anyone know what kernels the ax25 patch works on, and/or
what I'm doing wrong on this compilation?
TIA,
