This is pretty much a stock FC3 install, with the latest updates.
ppp-2.4.2-6.4.FC3
kernel-2.6.12-1.1372_FC3

I'm not exactly sure which log you mean. There isn't much in
/var/log/messages. I have a /var/log/ppp directory, but it turns out to
be empty, so I don't see any log files there. What I do have is the raw
output (console) from the eznet and wvdial program. The following is
the output from the "eznet" program as it tries to connect:

Unfortunately, I'm not at all adept at setting up ppp chat scripts, so
I'm stuck with trying to use all the tools others have built on top of
ppp. Of course, tools are great when they work, but you're sort of up a
creek if they don't.....

This is the eznet config file for my RR connection:
------------------------------------
1 debug yes
1 expect0 ogin:
1 password something
1 phone 5074056
1 reply0 aolnet/ent.somebody@rochester.rr.com
1 service RR
1 user somebody@rochester.rr.com
------------------------------------

Notice the "reply0". This is not normally there, but I found a
reference to the "aolnet" response somewhere through Google, and when I
added this in, it worked fine. Note the following response when I dial
into Roadrunner service:

   Unfortunately, in the case of Netscape.net, this does the low level
modem sync, but then fails the authentication, and simply drops the line
after a few seconds. (BTW - what's the difference between pap-secrets
and chap-secrets?)

Yea, that sounds like it's my problem. I tried the "dumb" script, just
giving the dialup script, and that doesn't authenticate. I'm grabbing
at straws here, but it sounds like Netscape may need more than the
default DUN emulation.

Thanks for your response though!
