Yeah, the default in some versions of the axutils is to put stuff in
/usr/local/etc/ax25
rather than /etc/ax25. Some people put links in between the two directories
just to be sure.
If you compiled ax25-tools and libax25, you should be able to.
1. Make sure you're really running the right kernel. Sounds like you have
done this okay.
2. Compile or install the libax25 and ax25-tools and all that stuff.
3. Use Minicom, to talk to your TNC and set it to KISS mode.
4. Make an axports file -- like it says.
5 Run kissattach. Make sure to specify an ip address (man kissattach should
help)
6. Run kissparms to setup your TNC stuff like txdelay (Do a man kissparms)
7. Try doing a 'call [device] ke6i' or something, to see if the TNC lights up
and
transmits. If that happens, it's probably working.
Do not panic. If it were me, I'd stick with Caldera, if that's what you
already
have. I don't think moving to Redhat will make it any easier. (Though RedHat
has a nice rpm for running nntp, which I like a lot. Not sure about Caldera.)

I'm not sure yet how some of my posts are being sent twice. I'll be trying
to track the problem down and fix it.

Cost and availability of equipment ... chicken/egg problem.
That 56k link I costed out earlier in the thread jumps by
about $100 to $200 per end when placed on 1240 instead of 440.
If you tune the next three lower frequency bands here,
you get almost the same result. A vast wasteland.
Ditto for most of the HF bands most of the time.
10M makes a good troposcatter band for 1200 baud links ...

Rob:
Well the other wonderful about these bands is that those oceans of Hz (1,111
MHz) available to us can be re-used over and over again by simple
spatial/geographic re-use.
So if you get off the TV realy paths, and watch the geography and
interference then you can use those bands anyway.
And so . . . in practice we have available to us much more than the simple
1,111 MHz! We have that 1,111 MHz bandwidth multiplied by the number of
geographically separate "non-interference cells" that we choose to deploy.
Wow, talk about bandwidth to burn.
And we amateurs are sitting on our old 2 m and 70 cm allotments and letting
the commercial guys do all the innovation in this broadband area.
What happened to the old ham radio spirit of pioneering new areas for radio
and its' applications?
Many of us seem obsessed with moving backwards into the past and are missing
all of the wonderful opportunities in the future.
How can we hams best exploit the oceans of bandwidth available to us?
What we need to learn to do is to "waste" some of that bandwidth and trade
that for other factors/capabilities that we want/need. . .
Comments, thoughts?
