While we will not discuss every distribution, the steps are generally the same for all. Since using PPTP requires root access, it is not a bad idea to use a program such as sudo or similar tool to control access to this critical component or to use the PPTP service setup with pptp-command.

As an added bonus the current PPTP modules...
