Thank you very much for your patch! It is working absolutely great and as I
hoped it would (pppd-2.4.5)!
As I think you might have had other similar problems we have, what are your
experiences with openl2tp for dialin users in a large scale? Are there
problems still unsolved?
Currently I'm having trouble monitoring mlppp bundles. Is there any
reasonable and reliable way to check how many ppp links are in a bundle and
if they are up and running?
Because of it's nature, there aren't any pid files in /var/run/ except for
the bundle, ip, ifconfig and netstat aren't of any help, too. Is there any
status plugin, that is multilink aware?
We are still looking for a patch to get pppd to name it's interfaces
ppp[PID] instead of ppp[incrementor], just changing the ifname didn't work
(of course ;)
# diff main.c.orig main.c

RADATTR plugin removed file /var/run/radattr.ppp31763.
I know that rp-l2tp provides an option to set interface names with PID, but
we are using OpenL2TP ;)
Again, Ben, thanks a lot for your patch, you saved my day!
Thanks for any other hint to anybody how want's to help me out on the other
issues ;)
Greetings,
Johannes Jakob
