[pptp-server] poptop and NT 5 (windows 2000)

[tmk]

After testing out the latest version of poptop, and installing the mppe
patch, I'm happy to report that both work. If you are using an older version
of poptop, a few config problems prevent it from working with NT 5, but as
of v0.9.5 poptop and NT5 work just fine together.

For those of you new to the list, here's a repost of the steps you need to
take to get encryption working [edited a bit in light of my experience]:

Installing MSCHAP/MPPE PPPD Patch

Grab yourself a clean copy of the PPP deamon version 2.3.8 (ppp-2.3.8).
Iusually go here for my PPP files: ftp://cs.anu.edu.au/pub/software/ppp/

Grab youself the MSCHAP/MPPE diff files and the RC4 files
[instructions for obtaining RC4 files will be in the file README.MPPE after
you apply the diff to pppd ] -tmk
[note: if you get them from the SSL site, they are actually IN the ssl
archive file.. not floating around on the ftp] -tmk

Follow these instructions:
Note: [] are example commands to run

* extract the archive to your local file system [tar xvzf ppp-2.3.8.tgz].
* copy the MSCHAP/MPPE diff file to ppp-2.3.8/
* extract the diff file [gunzip ppp-2.3.8-mppe-others-norc4_TH7.diff.gz]
* patch the diff [patch -p1 < ppp-2.3.8-mppe-others-norc4_TH7.diff]
* copy the RC4 files (rc4.h and rc4_enc.c) to ppp-2.3.8/linux/
* [cd ppp-2.3.8]
* [./configure]
* [cd linux]
* [./kinstall.sh]
or "make kernel"
* [cd ..]
* [make]
* make a backup of your pppd if your so inclined
* copy the new pppd over the old one [cat pppd/pppd > `which pppd`]
  or do "make install"
* [cd /usr/src/linux]
* [make modules SUBDIRS=drivers/net]
* [make modules_install]
You may have to copy the rc4 files to /usr/src/linux/drivers/net and\or
/usr/src/linux/include/linux
* [rmmod ppp]
* [insmod ppp]
above 2 lines if you installed ppp as a module
* [insmod ppp_mppe]

Here is an example PPP options file (/etc/ppp/options):

lock
debug
auth
+chap
+chapms
+chapms-v2
mppe-40
mppe-128
mppe-stateless


Here is an example chap-secrets file (/etc/ppp/chap-secrets)

username * password *

this allows username to log in to any host(server) with password and any ip
address
-tmk

Setup your Windows client to support data encryption. Run PoPToP and
connect!
