[ale] need working dialup

Let me clarify again.
Using chat you authenticate like a typical serial connection using
expect send pairs. Only after you have authenticated with the radius
server this way are you allowed to start the ppp process. Your already
authenticated as a user so the PPP servers respond with the first part
of PPP called LCP which goes by quickly and you get into Pap/Chap
authentication (earthlink uses Pap). After pap authenticates then you
receive an IP, gateway, and so on. After that encapsulated data flows
which is your real pipe to the internet. Oreilly has a great book on
PPP that is a bit old but well worth the cost since the protocol hasn't
changed at all. I used it for working thru Linux and IRIX PPP
connections over dialup and then later for debugging PPPoE over DSL.
Several times when Earthlink would change their methods for connection,
I would get nothing more than what you get with the LCP. I'd have the
ATM connection from the DSLAM unit out on the street but no response
from the PPP servers.
Theoretically, if you login successfully to the dialup server and PPP
fails in LCP then probably something is wrong at Earthlink. But, you'd
have to have a Win box to trouble shoot with if you get Earthlink
involved. They'll try to make you reinstall Windoze if your not
politely tough on the phone. You can't budge an inch and you can't have
any cracks in your information. Everyone on the list knows the drill by
now. ;-)
I would go to the simplest method. Configure wvdial with the barest
bones configuration. A simple email address and password. Let it use
it's defaults and attempt a connection. If that fails then try
different connection numbers. If you still get the same behavior then
someting is wrong.
Check for successfully Radius login/password responses in your chat
script log.
If you get that then start looking at PPP messages.
If you fail during LCP then call earthlink and complain.
If you fail during Pap then check your not forcing chap instead of pap.
If you never get an IP then you may be tining out on a busy dialup server.
If you can't seem to resolve DNS or ping anything but see an IP in your
logs, then set the gateway and DNS manually.
I can't think of anything else. Since you see the CONNECT response,
make sure that it is coming from the Radius server and isn't a bogus
response from your chat script when it connects to the modem. Do you
hear the boingboing shshshsh of the serial connection negotiating?
(Nobody laugh too much as you've been at this point sometime) If you
hear that and it goes quiet without disconnecting and THEN you get the
CONNECT response, you should have the chat script "expect" the "ogin:"
or "gin:"
Keep going from there and post back. PPP and serial connections were a
real mystery until I got the O'Reilly book.
Merry Christmas!
