Segfault from PPTP on Fiesty

I see the following when trying to connect to a PPTP VPN configured using the instructions at http://pptpclient.sourceforge.net/howto-ubuntu.phtml

Code:

Apr  7 00:45:13 gemini kernel: [ 1869.627601] nm-ppp-auth-dia[7983]: segfault at 0000000000000088 rip 00002b356c4da21b rsp 00007fff44161a70 error 4

Anyone seen this before and know how to fix it?

Same for me. But using pptp directly always work. If I reboot my computer several times it works, but only some time.

I (a newbie) have the same problem. Can this be a 64bit issue?

after downloading the sources from the svn repository and building the NetworkManager/vpn-deampns/pptp I have now VPN and the nm-ppp-auth-dialog up and running. It was however necessary to modify the /etc/NetworkManager/VPN/nm-ppp-starter.name like this:

Quote:

#auth-dialog=/usr/lib/network-manager/nm-ppp-auth-dialog
#properties=/usr/lib/network-manager/libnm-ppp-properties
auth-dialog=/usr/libexec/nm-ppp-auth-dialog
properties=/usr/lib/libnm-ppp-properties

because make install has installed the binaries under /usr/libexec und /usr/lib/ and not under /usr/lib/network-manager.

At some point I also called:

Quote:

./autogen.sh --prefix=/usr --enable-nm-vpn-dbus-old

to get rid of a compilation error.

Compiling and installing the NetworkManager from the sources didn't work, therefore I reinstalled the network-manager with apt-get remove/install, and executed afterwards make install under vpn-deamons/pptp.

I guess, I was not quite sure what I'm doing, but it works now

I found this http://www.students.ncl.ac.uk/a.j.me...sh-workaround/
while trying to solve the problem.
It seems to work. Problem is that I'm getting this now:

Code:

Apr 20 09:12:34 GEMINI pppd[12590]: Plugin nm-pppd-plugin.so loaded.

Apr 20 09:12:45 GEMINI pppd[12602]: Terminating on signal 15

Looking online it looks like I might have the auth type incorrect.
At least its not segfaulting now

I am seeing the same thing here, but am not sure if it's a problem with my configuration or not. Would be interested in knowing what others think.
