IPCP, CCP and LCP are now just derived FSMs.
Comment each of the FSM implementations so that we can
tell what's going on.
Revise the state transitions so that CCP and IPCP actually
send terminate REQs when appropriate.
The OS & IPCP layers are still like spagetti (next job).
This program was originally written by Toshiharu OHNO <tony-o@iij.ad.jp>,
and was submitted to FreeBSD-2.0.5 by Atsushi Murai <amurai@spec.co.jp>.
The original version was usually referred to as iij-ppp.
Ppp is currently maintained under FreeBSD and OpenBSD by Brian Somers
<brian@Awfulhak.org>. The sources for both operating systems are the
same although the Makefiles vary due to the nature of each system.
If and when it's ported to another OS, things will probably be shuffled
around so that there are several Makefiles, one per architecture.
The latest sources are available in FreeBSD-current and OpenBSD-current.
An archive hacked so that it will build on just about any version of
FreeBSD is frequently generated and made available on
http://www.FreeBSD.org/~brian. Once the first OpenBSD release is made
with ppp, an up-to-date OpenBSD archive will be made available too.
A FAQ is available at http://www.FreeBSD.org/FAQ/userppp.html. It applies
equally to OpenBSD as it does to FreeBSD. The man page is quite extensive,
and there are lots of examples in /etc/ppp/ppp.*.sample. These examples
come with the hacked archive above but must be installed manually.
Ppp is still under development. There is no official TODO list.
