I run RedHat5.1. I am attempting to dial into a NT4.0 running RAS. I cannot seem to get a login session going.

Is the modem answering?  Assuming it is, here are some things to check:

1.  Make sure your RAS server doesn't require 'Microsoft Encrypted Authentication.'
2.  Make sure your RAS server allows TCP/IP connections.
3.  Check to be sure your user account on the RAS server has dialup rights.

     Hope this helps. . .give us some more details on the problem.  What exactly happens when you try to connect?

I am the admin of the NT platform as well, All of those options are checked.

To expand the info. The modem does indeed answer and establish a connection, at the point you would expect to see a login propmpt nothing happens. Also, I am running this NT server as a PDC of the domain.
I have encountered a similar problem with Win3.1 running Trumpet. Was OK before Domain control.

Does the LINUX machine dial into a regular ISP?  In other words, is the LINUX box setup to run PPP, etc.?

I do not attach to an ISP, in a sense I am my own ISP .

The Linux box is set up for PPP, I even tried it under Minicom, at the point you would expect to see some garbage on the screen, it goes silent and after ~15 sec. the line times out with an authentication error at the NT end.
I don't really know, but my suspicion lies in the domain stuff of the NT ( ???? ).
This is my first cut at RH5.1 , I normally work in the ATT systems. The PPP was set up several diferent ways, all with the same result. Using Minicom, I would expect to see something going over the line which I then could interpret.
Thanks for your help.

Are you able to successfully dial in to the RAS system via NT and/or 95 clients?

Which version of PPP are you using ?
some older version does not support MS-CHAP handshake. You need a patch for this.
Use the debug option of PPPD (-d -k n). you will get many info in yor syslog file.
Are you using CHAP or PAP ?
In both cases you have to set up correctly the files
chap-secrets or pap-secrets.
you need two entry in the file chap-secrets and one in pap-secrets.

One thing that helped me out most was the HOWTO-PPP file in the linux distribution.
