I have a VPN client configured for using PPTP under Ubuntu 9.10 (the alpha version, but fully up to date). The configuration has everything enabled except for EAP (I found I had to uncheck that to make it work).
It worked fine until Tuesday of this week. It now fails with a message: "VPN Connection Failed".
The message in /var/log/messages when it worked on Tuesday is:
Plugin /usr/lib/pppd/2.4.5//nm-pptp-pppd-plugin.so loaded. pppd 2.4.5 started by root, uid 0 Using interface ppp0 ppp0 <--> /dev/pts/2 CHAP authentication succeeded MPPE 128-bit stateless compression enabled local IP address XXX.XXX.XXX.XXX remote IP address XXX.XXX.XXX.XXX primary DNS address XXX.XXX.XXX.XXX secondary DNS address XXX.XXX.XXX.XXX
Now it has changed to:
Plugin /usr/lib/pppd/2.4.5//nm-pptp-pppd-plugin.so loaded. pppd 2.4.5 started by root, uid 0 Using interface ppp0 ppp0 <--> /dev/pts/3 Modem hangup Connection terminated. Exit.
I'm using Ubuntu 9.10 alpha; I'm using the standard network-manager applet to configure it (but have also tried kVPNc and manual configuration). The VPN is working fine-- I can connect to it using an XP virtual machine running on the system.
