There are many different flavors of pptp clients, most of them graphical.  Although if you're unfortunate enough to be on a MS (Windows) system, you're stuck with theirs and all of its limitations, those of us who are fortunate enough to be working on linux can do much better.  This article will focus on setting up PPTP (Point-To-Point Tunnelling Protocol) clients from the command line.  The huge advantage that we gain by switching to the CLI (Command Line Interface), is that we're no longer limited in the number of open connections we can have.  It's also a very great deal faster to use the command line, both for setup and connection, and it's really quite simple.
