Ubuntu VPN Using Network Manager

If you already have your JanusVM working with your iPhone, you can quickly setup your Ubuntu Laptop to use the VPN also. Give a quick sudo apt-get install network-manager-pptp and viola network manager now supports pptp configuration. Give a reboot, and you can configure the settings.

I was having a little trouble with the configuration at first, because I was accustomed to the automatic configuration of the iPhone. In the settings you want to enable peer authentication, and refuse chap. Also I had to disable compression otherwise authentication was failing. Then enable all three encryption options. Save, exit, attempt to connect. Enter the username and password you configured in JanusVM and you should connect just fine
