[SOLVED] Troubleshooting VPN (PPTP)

[neograven]

Looking around and doing some research, I found this:

http://svnweb.mageia.org/packages/cauldron/ppp/current/SPECS/ppp.spec?revision=33338&view=markup

Correct me if I'm wrong please.. this means that the ppp kernel module for Mageia is not compiled with the MPPC patch enabled?

[doktor5000]

Why do you think so? First there are some comments and the patch is defined:

Code: Select all

45    # (blino) http://orakel.tznetz.com/dload/ppp-2.4.4-mppe-mppc-1.1.patch.gz
46    # original patch on http://mppe-mppc.alphacron.de/
47    # (tpg) disable this patch, because it need a rediff and also there are some legal issues
48    # Although the module's source code is completely free, MPPC itself is patented algorithm.
49    #Patent for *Microsoft* PPC is holded by the Hifn Inc. This is obvious ;-).
50    #Furthermore, MPPE uses RC4[1] encryption algorithm which itself isn't patented,
51    #but RC4 is trademark of RSA Data Security Inc.
52    #To avoid legal problems, US citizens shouldn't use this module.
53    Patch11: ppp-2.4.4-mppe-mppc-1.1.patch

and then it gets applied:

Code: Select all

181    %patch11 -p1 -b .mppe_mppc

Ah, I see I didn't read far enough.. Gotcha!

Thanks for clarifying!

I will check out the RC once it's out (may go ahead and put Beta 3 on again) it looks like everything should be sorted. I'll post back if I find anything

UPDATE:

PPTP VPN does NOT work in Mageia2 RC either, however I did find out why. Please see this bug submission: https://bugs.mageia.org/show_bug.cgi?id=5741

Once I applied the RPMs with the correct PPP 2.4.5, everything works. I am suppying the links here in the even that anyone else who has problems connecting to M$ VPN via PPTP using MPPE will be able to apply these RPMs and get around the issue:

32 bit version (I haven't tested this one as I use 64bit, but there are others that have verified this solved their problem on Mageia 32bit):
ftp://ftp.crashrecovery.org/pub/linux/p ... 0.i586.rpm

64 bit version:
ftp://ftp.crashrecovery.org/pub/linux/p ... x86_64.rpm

Finally! Those of us stuck with M$ MPPE PPTP VPN can work!

I can confirm:
using Networkmanager and neograven's package MPPE works in mageia2

However if you have net_applet,
ppp will not work at all (not only VPN with MPPE)
i.e you have to use networkmanager

ppp will not work at all (not only VPN with MPPE)
i.e you have to use networkmanager

This is quite a generalisation - so why did it work for me with my UMTS stick?

This is quite a generalisation

sure, I didn't made a lot of tests, but this is my experience:

I had ppp working with net_applet (with an usb stick)
I needed to use a vpn, but it was impossible to have a connection;
with mdv and mga1 I was used to run "pppd call pptp_vpn",
but mga2 complains about the mppe setting in /etc/ppp/options.pptp

so I installed the 2011mdv package linked by neograven and I was unable to use my usb stick;
I tried to use the vpn over a wifi connection and it didn't work too.

so I installed networkmanager and now I have both the usb stick and the vpn working.

[neograven]

Yea, the packages were for use with NetworkManager, not the applet.
