[Gllug] What is /dev/sit0 ?

[Dylan]

Hi all,

While aimlessly poking (or should that be peeking) around, I noticed that 
hwinfo reports four network interfaces: lo, eth0, eth1, sit0 . So, that's the 
loopback, and two ethernet cards - so far so good... But what is sit0? A 
google suggests is something to do with IP6 or ppp tunnels, but I don't see 
why either of these would be set up here.

Cheers
Dylan
