[ale] Q: 'pptp'+'mppe' installed, but not yet configured

[Geoffrey]

I think part of your problem is going to be going to the vpn as well as 
the internet.  You'll have a single set of DNS that will point you 
either to the vpn or to the internet.  You can't have both.  If your DNS 
points you to the vpn, then requests to the internet will route over the 
vpn.

What I had to do to get the dns updated with the ones provided by my vpn 
was to script them out of the messages log file and script them into 
/etc/resolv.conf

Until later: Geoffrey		esoteric at 3times25.net

I didn't have to buy my radio from a specific company to listen
to FM, why doesn't that apply to the Internet (anymore...)?
