Hi all
We can't seem to get ml-ppp to work in a stable way (nor PPPoE, nor
PPPoL2TP). Even when I found out the master_detach option, we compiled
2.4.7 but that didn't to the trick.
All links may fail, except for the one who created the bundle, if that
happens, the link goes down, if-down scripts are called, and all other
links are nicely closed.
Does anybody have a solution for that?
P.S. tried killing pppd with the HUP signal (as mentioned in the man),
tried interrupting the link somewhere in the middle, so the LCP fails,
nothing has helped me so far
kind regards
Arne

This works here without any problems (using SIGHUP). We use the latest
Linux kernels from the 3.14 and 3.16 branches (3.14.19 and 3.16.3 at
the moment) and pppd 2.4.6. However, pppd is heavily patched as we
implemented Dial-on-Demand over ML bundles, which is not possible with
the stock pppd. I'm afraid I haven't found the time yet to send the
patches upstream :-/ But you can look into them by yourself:

What happens if you send a SIGHUP to the master pppd? Is there nothing
in the logs?
