This HOWTO assumes that you are using a Linux 1.2.x kernel with the PPP 2.1.2 software or Linux 1.3.X/2.0.x and PPP 2.2
It is possible to use PPP 2.2.0 with kernel 1.2.13. However, to do so requires kernel patches. This document does NOT cover this mix of software.
Also, you should particularly not that you cannot use the PPP 2.1.2 software with Linux kernel version 2.0.X.
Please note that this document does NOT cover problems arising from
the use of loadable modules for Linux kernel 2.0.x. Please see the
kerneld mini-HOWTO and the kernel/module 2.0.x documentation (in the
Linux 2.0.x source tree at /usr/src/linux/Documentation/...).
As this document is designed to assist new users, it is highly recommended that you use a version of Linux and the appropriate PPP version that are known to be stable together.
