Проблемы с dial-in

Включи debug и покажи логи.

В некоторых дистрибутивах бинарник mgetty был собран без AutoPPP, поэтому хоть включай его, хоть выключай - толку чуть. Логи надо смотреть,mgetty -x 5 например.

А в pap-secrets записали логин, пароль и удаленный IP?

Отключи под Win9x в свойствах соединения шифрование пароля. 70%
проблем с которыми я сталкивался связаны именно с этим, конечно при
условии, что dial-up cервер настроен верно и софтверных проблем
под Linux тоже нет.
Вобщем поддержу остальных: покажи логи.

а у тебя опция login невключена часом ?? отключи....
