Is there a way within /etc/ppp/ip-down to know whether the
link is being terminated because of a system shutdown vs
any other reason? There are actions I don't want the
script to do if the system is being shutdown.

I'm running kernel 2.6.14, ppp-2.4.3 and rp-pppoe-3.6
This is not a specific distribution. It's my own setup,
but all of the standard tools/utilities are in place.

Thanks!

On system shutdown with sysV style first the kills from the startup script
for the shutdown runlevel are run. Then programs are sent a kill. Then
programs are sent a kill -9 which means that there is nothing the program
can do. So you could put in pppd kill script into the shutdown runlevel
which sets an environment variable which ip-down reads or what would
probably work better a file is touched ( and removed by the ip-down script
so it does not hang around for the next time) and if that file exists,
ip-down differs in its shutdown.

A secret is it? "I won't tell you anything about my system but can you help
me?" There are no "standard tools/utilities" each distro differs For
example as I understand, debian run-levels are very different from
Redhat/Mandrake runlevels, etc.

Excellent idea. Thank you.
