Hello all,
I've been using the 64-bit version of Suse Linux Professional on a dual AMD
Opteron system since the first x86_64 release (= Suse 9.1). Ever since that
time, I've been trying to establish a PPTP VPN connection to my company's
VPN gateway. However, all my attempts were unsuccessful. Each time a new
release came out, I upgraded to this release in the hope that the problem
would be fixed. Currently, I'm running Suse Linux Professional 9.3. But
still, the problem has not been resolved.
In the meantime I discovered that I can succesfully establish a PPTP VPN
connection using MS-CHAPv2 in the 32-bit version of Suse (tested under
VMWare). In the 64-bit version of the PPTP-client, the whole system freezes
when the PPTP-connection is being established. I use pptp-command to setup
and establish the VPN connection.
Below are the specs of my system configuration :
