Well why take the bother of changing runtime parameters in the kernel when
with a simple script at boottime or when ever you want for that matter, they
can be changed.
If they were hard cored into the kernel we would then need to "reinstate"
the old axparms system from ax25-utils-2.0.12 and lower.

You can change all the parameters described in the HOWTO, see 6.2, with the
execption of nummber 15.
If you want to have axdiging then you will need a small program called
axdigi. I belive it can be found at:
ftp.pspt.fi/pub/ham/linux/ax25

So in one of your startup scripts do something like the following after the
interfaces have been attached.

echo 50 > /proc/sys/net/ax25/ax0/t1_timeout

The default is 100 which is 10 seconds now you will have 5 seconds timeout.
Do not add the >/dev/null as suggested by someone else, it will send the
output of the command to /dev/null (nowhere) and will not change the
parameter value, at least not on any of my machines.

It is documented in the HOWTO, also its documented in the following
directorys.
/usr/src/linux/Documentation/networking/Configurable
/usr/src/linux/net/TUNABLE

Unfortunatly the TUNABLE file in 2.0.33 and lower does not explane that if
we use ax25-modules patches then we can use the sysctl interface for ax25
and netrom devices.
