In RHL 4.2, for some reason the 4th field in the pap-secrets
file had to not be there, or dialup wouldn't work. With 5.2
it must be there.
A few lines of examples in the comments at the top of the
file would help a lot.
For dialin users, an example line would be:
fred dialin "" *
assuming the mgetty setup for autoPPP is modified to have
the "login" and "name dialup" items added to the autoPPP
line (recommended as well).
Thank you for your suggestion. It has been noted and will be relayed
to a developer.
