[pptp-server] ppp-2.3.10 make kernel problem plus how to get 128 bit VPN connection

[Patrick Reid]

I found out what the source of the problem with getting my encrypted
connections going was - running make kernel for ppp-2.3.10 skipped copying a
bunch of files which needed to be updated to support an encrypted
connection. I had to manually compare the files and copy those which weren't
the same as in the ppp-2.3.10 over into the Linux directory tree. (This was
in RH 6.0, kernel 2.2.5-15).

Also, I managed to get a 128 bit VPN connection going. You can download the
128 bit version of the Windows 98 Dial-Up Networking Security Update from
the following URL: http://support.microsoft.com/Support/NTServer/128Eula.asp

(that is, if you are in the US or Canada).

Accept the EULA, then choose the appropriate 128-bit DUN Update. (There also
a 128-bit update for Win 95 DUN 1.3 as well as for Win 98 - I used the Win
98 one and can only assume that the Win 95 one will work just the same). You
should also download DUN40.EXE (or maybe vpnupd.exe: I used DUN40.EXE) and
install it before continuing, I think.

The downloaded file is called Msnt128.exe. When I tried to execute it, I got
a message saying that the installed version of dial-up networking was the
wrong one. However, if you have WinZip installed on your machine, you can
extract all of the compressed files from the executable. If you do so, you
will find that one of them is called dun128.inf. Right-click on this file
and choose "Install." I rebooted once the install completed, but that may
not be necessary. The package puts the following files in the windows\system
directory:

dun128.doc
pppmac.vxd
pppmac.40
rasapi32.dll
rnaapp.exe

pppmac.40 is a backup of the existing pppmac.vxd (which is why I suggested
installing DUN40.EXE first). The dun128.inf install also copies dun128.inf
to the windows\inf directory.

Once my machine came back from the reboot, I was able to set up a 128-bit
encrypted VPN link to PoPToP.
