Struggling with AX.25
I have been struggling with AX.25 for days trying to make it work and I'm hoping someone can help me. My setup consists of a basic Debian 3.1 install running on Pentium II 400 Celeron with 64 megs of RAM and a custom
2.4.33.4 kernel with AX.25 support compiled directly in.
I have installed libax25, ax25-tool, and ax25-apps from the repositories and they appear to be installed and working correctly.
My problem is this. I can not get two known working TNC's working in KISS mode with this setup. At first, I thought it might have been something in the kernel, I was originally using the kernel that got installed by default, so I downloaded and compiled the latest
2.4 kernel. I have /etc/ax25/axports setup correctly, and running KISSATTACH yields me an ax0 device:
n1vlv-debian:~# ifconfig ax0
ax0 Link encap:AMPR AX.25 HWaddr N1VLV-10
inet addr:
192.168.144.39 Bcast:192.168.144.255 Mask:255.255.255.0
UP BROADCAST RUNNING MTU:512 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:6 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:10
RX bytes:0 (0.0 b) TX bytes:108 (108.0 b)
I have also tried various settings using KISSPARMS, etc. I can communicate with the TNC's in command mode using minicom, so that would rule out the possibility of any cabling problems etc. I am also running a null modem adapter on one end.
When I run listen and hear packets, I see nothing on the display. When I attempt to connect to one of our local nodes using call, nothing happens, the radio does not key and it just hangs saying:
GW4PTS AX.25
Connect v1.11
Trying...
And that is as far as I get. I also checked the serial port params using stty:
n1vlv-debian:~# stty
speed 38400 baud; line = 0;
-brkint -imaxbel
Noticing that it was set to 38400 baud, I changed my axports and TNC to match. Not even really sure if this has any bearing impact on it, but tested it anyhow and I am getting the same results.
I am really out of ideas at this point and I'm about to reach my wits end. If someone could help me that would be greatly appreciated.
