I've been with Concentric for a while now and I don't haven't had a
lot of complaints.  They did send me a *-gram for staying online
too much (like, always). Unlimited access isn't really so unlimited,
it seems.

Anyway, maybe it's different depending on your POP, but I had no
problem at all.  I don't have my config handy, but as I recall I
just have my login and password in pap-secrets and a simple chat
script that only dials and connects.

I don't need a chat script that logs in with my login and password,
Concentric checks for a ppp connection as soon as you connect (at
least on my POP).  If it gets a ppp connection it uses PAP to do the

I've seen MS-CHAP connections that required NTDOMAIN/USER, but I've never
seen it the other way around.  If Concentric starts mucking around with
my account I'm gone.  

Does anyone keep a list of Linux-friendly ISPs?

1. PPP and Concentric networks dialin

PPP is driving me nuts!!!  

I have a ppp account with concentric networks.  I use windows NT and
linux.  I'd like to not have to use NT anymore, but For the life of me I
just can't seem to get the dialup to work under linux.  I first tried
the graphical dialers, (e.g., rp3, etc.) all they would do is lock up
the modem, requiring a reboot.  SO next I started writing my own scrips
with chat.  All seemed good.  Now here is the WEIRD part...

When I set up a dialup connection in NT and and enter my login and
password, everything connects fine (in fact I'm using it now).  However,
if I try to login manually using the NT dialup networking, or I try to
login using hyperterminal, it always rejects my username and password.
I've checked and double checked to make sure I'm doing it right.  WHY
does it work with the automated NT Dialer, but not with a manual
