[gentoo-user] PPTP + MPPE + pptpconfig + Kernel 2.6.15 + ndiswrapper -> unstable connectivity

[Justin Hart]

Hi,

I recently upgraded my kernel to 2.6.15, enabling MPPE so I could
connect to my campus network's VPN.

I'm using pptpconfig to set up the connection.  It's plain-vanilla,
name of the server and such with the require_mppe box checked.

I'm connecting via 802.11g, using ndiswrapper to by Broadcom 3150
wireless adapter.

If I have this configuration, as it is now, on my campus network, the
connection drops after a few minutes.  It also drops my wi-fi
connection.  I kill dhcpcd and restart it to re-acquire an IP, and
life is good again.  The wi-fi connection is stable unless I do this.

from:
http://gentoo-wiki.com/HOWTO_Set_up_a_vpn_client_with_mppe_encryption

It contains this line:
You will have to install or recompile ppp with the mppe-mppc USE flag. 


The aforementioned wiki also has other suggestions that might be relevant
to your setup,, particularly in the attached scripts. If not, consider  
posting a new wiki, as I have been
'tagged' to setup a gentoo laptop for a friend with secure wireless access
on a university campus......  

Are you happy with the performance of your BC 3150 card?
Any other  pc-card hardware recommnedations as it'd be nice to get one card 
that works well with Gentoo and winDoz on a dual-boot laptop?

Lots of interlopers and curious talent on those university grounds....

hth,
James

Hrmm.  I followed that wiki when I set it up originally (back when you
had to find kernel patches).  It never used to drop my connections,
but seems to do so now.  Definately have the use variables set up
properly.

I'm ecstatic with the performance of the BC 3150, though, it was a bit
of a pain at first under the new kernel (it freezes (ndiswrapper that
is, during modprobe) if you have kernel module unloading enabled...
wierd).

I've thought about updating the wiki a bit.  IIRC, it still reflects
needing to track down kernel patches.

Thanks for the help though.

sorry to hijack the thread, but I use a Broadcom BCM4306 802.11b/g
mini-pci card in my laptop, and it works great between windows and linux
with ndiswrapper.  Don't use ndiswrapper 1.7 yet though :)

HTH,
