mppe Fedora Core 1 mppe not supported

I have followed the instructions at
http://pptpclient.sourceforge.net/howto-fedora.phtml

I get a 'kernel does not support mppe' message. I am confused: all the
rpms in steps b+ install without complaint. I use rpm -iv and it looks
like a clean install. But obviously something is wrong.

I have the source for my kernel /usr/src/linux-2.4.22-1.2199.nptl/kernel
and I have gcc and cpp 3.2.2 so I skipped the instructions in 1a thinking
I was up to date.

Something is wrong though:

The instructions say kernel-source-2.4.22-1.2115.nptl.i386.rpm - which is
not the source for my kernel - so I think probably the docs aren't quite
up to date? Shouldn't I be using the source for my kernel?

Also I had to use modprobe ppp_mppe. The instructions say modprobe
ppp-compress-18, but that didn't work for me even though my modules.conf
sets alias ppp-compress-18 mppe.

I have rebooted. I am running pptpconfig as root.

The mppe kernel does not show up on my grub menu, though. Should it?

I don't know how you could boot to it otherwise. Apparently the Grub
menu wasn't configured to include it as a kernel choice.

Ok this morning I booted up again, did modprobe mppe and received a
warning about 'taint the kernel', but I have read to ignore that so I ran
pptpconfig and easily got a connection to my employers vpn.

After work today I booted up again - I'm working on a laptop so I don't
leave it running all the time - and modprobe can not find mppe or
ppp-compress-18!

Although rpm insists that kernel-mppe-2.4.22-1.2199.nptl is installed,
whereis can not find mppe anywhere.

What's going on? The machine was off all day.

This is very perplexing.

Here is my modules.conf
alias eth0 8139too
alias usb-controller usb-uhci
alias sound-slot-0 i810_audio
alias ppp-compress-18 mppe
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L
>/dev/null 2>&1 || : pre-remove sound-slot-0 /bin/aumix-minimal -f
/etc/.aumixrc -S >/dev/null 2>&1 || :

If the kernel supports MPPE then it isn't a standard kernel. That is,
it's modified, presumably by whomever distributes "Fedora Core 1."

A "modprobe -c" here, from module-init-tools version 3.0 (modprobe -V),
shows ppp_mppe is the module for a kernel that knows it by the name
ppp-compress-18, but I can find no MPPE configuration implemented in
the standard 2.4.26 (or even 2.6.7) kernel source.

That certainly is bad behavior on the part of something, but I don't
know what.

Do "uname -r" to find the version of the running kernel. Whereis only
searches for certain types of file in certain places. It's likely that
it doesn't look for a kernel module. Try "locate mppe" .

Beats me. But it sounds like you might be booting to different kernels.

Indeed. Only someone who has had a similar experience with Fedora is
likely to *know* what causes the problem.

I've never seen anything like the last 3 lines (or one wrapped)
in modules.conf, which is not to say that they are not meaningful -
according to "man modules.conf" there _is_ a "post-install module
command ..." directive for modules.conf.

It may help to know that all kernel modules should_ be in subdirectories
of /lib/modules/`uname -r`/ . Also "lsmod" shows the inserted modules.

Poking around I saw it looked like mppe was in the kernel - not in
the modules! So on a hunch, I removed from modules.conf :

alias ppp-compress-18 mppe

This seems to have solved the problem. I don't need modprobe at all.
Perhaps the instructions are out of date for the mppe kernel version? Or
perhaps I'm just too dangerous to be poking around at this level.

Thanks.
