Hi,
I'm trying to use Netgraph (mpd) as a PPPoE access concentrator
(i.e. PPPoE server). It is working OK but with one minor potential
problem which I haven't been able to solve.
The following is the mpd log file (replacing ip addresses with
XXX.XXX.XXX.XXX) and configuration files. As we see in this log, the
first incoming request succeeds and operates normally. However,
"device" seems to be getting an attempt to bring it up again right
after the first call is disconnected. This attempt never succeeds and
is repeated indefinitely.
Even in this state, subsequent PPPoE incoming request succeeds, so
this is not a significant problem, but I just don't feel
comfortable. Can anyone can give me an advice to get this problem
solved? Thanks!
