Well, it can't really.  Ppp switches to uid 0 before opening 
/dev/tunX and then switches back to its normal uid.  I was really 
speculating here 'cos I thought this might be the same problem as 
we're seeing in the -stable snapshot releases.

The -stable problem's been fixed now though, and you're running 3.1 - 
so I was a bit off course :-(

Are you using a GENERIC kernel, or have you installed your own ?  If 
you run ``ifconfig -l'' it should list tun0 as one of the interfaces. 
Assuming that it does, and that /dev/tun0 exists and lools like this:

$ ls -ln /dev/tun0
crw-------  1 66  68   52,   0 Aug 31 16:49 /dev/tun0

and that ppp itself looks like this (bar size differences):

$ ls -ln /usr/sbin/ppp
-r-sr-xr--  1 0  69  239568 Aug 25 21:08 /usr/sbin/ppp

I can't imagine much going wrong...
