Hi James,

The problem is due to a change in pppd defaults.  It used to not require the 
remote system to authenticate itself, but now it is required.  You have a 
few options to fix this, including:
Run kppp as suid root, and provide the option "noauth"
Edit the default arguments of pppd and replace "auth" with "noauth".  You 
will have to be root to do this.

Hope that helps.
