Terry is well aware of the current situation. He is just very busy with
other higher priority projects so AX25-howto will probably have to wait.

I guess Bob overestimated the amateur commutitys ability to adapt
slightly inaccurate information to the current situation. Oh well...

The official and best place to get a kernel is ftp/www.kernel.org and its
mirrors. There is a list of the available mirrors at
http://www.kernel.org/mirrors/. For you Gerd it would be
ftp.de.kernel.org, for me ftp.fi.kernel.org and so on.

There is _NO_ excuse for using a kernel other than 2.0.36 or 2.2.5. So the
above list compresses to:
linux-2.0.36 (no patch module needed) ax25-utils-2.1.42a.tar.gz
linux-2.2.5 (no patch module needed) ax25-utils-2.1.42a.tar.gz
No need to confuse people with anything else.

Argh... For AX.25 there is almost no change from 2.0.36 (other than stuff
_inside_ the kernel, invisible to userspace). The change of max.
digipeaters is perhaps the biggest and will only need a recompile of the
utils. The other changes are minor and need only little tweaking of the
utils source. Glibc is the one causing bigger problems.

What? I have a 120 MHz pentium at home. It currently has 64MB but I used
it for a while with 32MB and it was quite usable. And I run X all the
time, with uptimes of couple of weeks. Admitted that running memory
leaking applications like netscape made it swap quite a lot but it was
usable. I haven't done any objective testing but in my opinion 2.0.36 was
slower and less usable.
