o Deal with LQRs when the peer has denied LQR, and we've
accepted and enabled LQR.
In this scenario, we send ECHO LQR packets (which the
peer *must* reply to) so that we can detect a dead
link. The peer however is sending LQRs. We now reply
to the peers LQRs without interrupting our own ECHO LQR
transmissions.
o Also, also only PROTO_REJ LQRs if we haven't actually sent
an LQR ourself - otherwise we REJ all the replies and die
because of reply starvation (duh!).
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.
