L2TP server on Linux

[Michael Torrie]

Does anyone have any experience setting up a vpn server on linux that
can handle L2TP (or alternatively PPTP), as supported natively by OS X
(and the ipod touch!)?  A casual search of Google reveals lots of
scattered docs, but no "howto."  I've set up openvpn before, but this
seems like a different beast. IPSec really.

In case anyone is interested, I'm really trying to get this going so I
can, using a very convoluted process, use amarok over vnc to connect
remotely (through the vpn) back to my ipod to add or remove music and
video from it.  From the ipod.  While half-way around the world from my
home machine.  Good thoughts anyway.  But if I can figure out this L2TP
thing (or is PPTP better?), I'll be laughing.
