I am trying to set up a PPP Tunnel with SSH (for a simple VPN) .. except it has not been simple

I was folllowing the instructions in "Building Linux Virtual Private Networks" by Oleg K and also the instructions on http://www.tldp.org/HOWTO/ppp-ssh/index.html

I am stuck on the ppp part. When I run the command
"sudo /usr/sbin/pppd noauth" nothting happens. (you are supposed to get a bunch of mubo jumble on the screen)

I tried running just "/usr/sbin/pppd noauth" as root and had the same result ...

I checked the messages file and saw the following error.


pppd 2.4.2 started by root, uid0
Using interface ppp0
Conect: ppp0 <--> /dev/tty2
LCP: timeout sending Config-Requests
Connection teminated
Exit


I do not have a ppp0 adaptor when I run ifconfig and I am not sure if that is part of the problem ... If anyone has any sugestions, it would be greatly appriciated. I am running Fedora Core2. I also tied on RH9 and received the same result.

Thanks
Peter
