Hello Scott,
Thanks for the tutorial. I kind of thought that was the way it worked.
However; see below. I made the changes suggested in the
temporary /etc/resolv.conf file about not changing the nameservers.
Now /etc/resolv.conf is GONE! dissapeared !

Don't know what service pppd is.

There was not the option listed in /etc/ppp/options

Now, since these above DNS numbers were so strange, I contacted my ISP.
They replied that they have not used those DNS numbers for several years
and that I should delete them wherever found and use the current set.
Did that. Changed them in /etc/ppp/resolv.conf. Then checked my ip-up,
ip-down, and pap-secrets files to, make sure everything was proper and
the same.
...................<more snip>................
Now the main problem. I can connect to the ISP just fine, but when I
go to get mail or a URL in my browser, I get the message, "Unknown host
- sanctum.com" (which is my provider) So, here I am, worse off than
when I started out. I tried to reverse all of my changes but that also
failed, probably due to the fact that the /etc/resolv.conf file is
missing and I could not regenerate it. I don't see any errors in any of
the log files. Why doesn't it see the host?
Please help!!
