VPN Slackware

I have some problems with VPN client for Slackware and I am not sure for the right solution.
I just change the ISP and the new one is on VPN. The ISP uses MSCHAP v2 . I found that I need to install kernel patch for MPPE (M$ point-to-point encryption) and support for MPPE in pppd.
On i think i found these. Can anyone tell me what does mean *-srt.tgz - is this a package or a source. And if it is a source is there a package in .tgz or I have compulsory to compile the source. ( compilation from source uses the linux kernel for any reason, but I did rm -r on /usr/src and I have no MBs needed on my HDD and I have to resize my partition) . My kernel is 2.4.22. And why this is so big - I have found .rpm-s only 200-300 KB ?
Thank you in advance!

this is readme from packge. regular source code

This package contains PPP MPPE kernel modules for 2.6.6ish kernels,
based on the CVS repository at
It was built into a DKMSified package by Matt Domsch.

patches/ contains several patch files, only some of which are used by
this dkms build.

- not used directly, but ppp-comp-local.h is the contents of this

- not used directly, but its interesting lines are in Makefile now.

- used directly, fixes up ppp_generic.c for MPPE.

The following patches were added by Matt to simplify the build:

- include ppp-comp-local.h

- include ppp-comp-local.h

- Change module license from "BSD without advertising clause" to "Dual
BSD/GPL", as is permitted and recommended when merging BSD-licensed
code into the GPL-licensed kernel.

* replace sha1 and arc4 implementations with those provided by the
kernel crypto library."

I got support in pppd now. But I did not found anythink for patching kernel for MPPE support. I changed a my kernel. Now I am with Slackware 10.0 kernel 2.4.26. Can anyone post a link with patch for 2.4.26 for MPPE support. After patching I must recompile the kernel with the new option in NETWORING OPTIONS.
Thank you!
