pptpclient, mppe and kernel 2.4.20

[dufeu]

I'm trying to get pptpclient working on my system which I recently (and happily) upgraded the kernel to 2.4.20.

I have discovered that I need support for mppe in the kernel. I have located a patch ( linux-2.4.19-openssl-0.9.6b-mppe.patch.gz ) however, I have a wee leetle problem.

I've never patched a kernel before. I have no idea where to start.

I have and am comfortable in setting kernel options and (re-)compiling my kernel.

Is there a process to see if this patch will work with the 2.4.20 kernel?

What are the steps in patching the kernel?

How can I find out if mppe support will ever be part of the kernel?

Am I correct in assume that mppe stands for Micro$oft Point to Point Encryption or reasonable facimile thereof?

I would like to connect to my machine at work, but my Win98SE (with 1.4 DUN upgrade) crashes regularly. I don't want to 'upgrade' to Win2K. I've been trying (almost completely successfully) to phase windoze completely out of my home.

Any help would be appreciated.

To patch the kern-
1)

[b3ast13]

Or you can try the MPPE/MPPC kernel module for Linux written by Jan Dubiec:

http://www.polbox.com/h/hs001/

In this case you need to patch also pppd.
In case you use only the mppe-patch, you don't need to patch pppd. The ebuild included in Gentoo already has the patch.

I know that if I do a string search for mppe in pppd, 35 instances are found. So the ppp patch is supposedly already in place. Or I've down something wrong.

Any advice?

The kernel compiled successfully.

I was able to get a connection using:

# pptp vpnserver call tunnel

I was not able to get a connection using either

# pppd call tunnel

or

# pptp-command
# 1) start

The message provided regarding trying to start with pptp-command was "insecure depency ... -T ...". The documentation as pptpclient.sourceforge.net says that I need an upgraded version of pptp-linux. This, unfortunately, doesn't appear to be available from portage.

I'll be looking into this some more but futher advice would be appreciated.



Thanx everyone!
