I am trying to set up my linux box to accept ppp connections using the /etc/passwd file for authorisation. I can get mgetty to detect the that the call is a ppp call and spawn pppd, but i can't get pppd authorisation working.

If I have this in my /usr/local/etc/mgetty+sendfax/login.conf

/AutoPPP/ a_ppp /usr/sbin/pppd

then someone can dial in, but no authentication happens.


if I have this,

/AutoPPP/ a_ppp /usr/sbin/pppd auth -chap +pap login

which is what I think should be happening, authentication always fails, even though the correct user/passwd (from /ec/passwd) is used.

I Suspect what I need is something in my /etc/ppp/pap-secrets but I can't work out what. Do I need a line for each user I want to be able to do ppp? or is there one magic line for all users?

Also once I have authorisation going I would like to track how much data is being sent to each users. How would I do that?

Are you supplying ip-numbers on one of the ends of the ppp-link? I think one of the pppd's needs to supply ip-numbers.

This response wasnt an answer, but a question, the answer to
which is that yes, at the moment the remote end is specifying
an IP; in any case a problem relating to specificying an ip
wouldnt be affected by whether or not my pppd is attempting
authorisation.

Commented:
What command-line do you use at the remote end?

Commented:
The remote end is a win95 client with the ip hardwired, and
user name/password as in the /etc/password file.

Hmm, that should work then, like it does here. The only thing I can think of is that you are using the shadow password suite and your pppd isn't compiled with shadow passwords. Or the reverse situation.
