Subject: [Netdisco] WG: error in daemon logfile
Hey everybody,
I still have the problem, that the netdisco 2 cron job (daemon) does not update
the database. I do not see any mac address on any switch still I start the
mucsuck by hand.
Does anyone have the same problem, or does anyone have an idea how I can debug
this?
Regards
Peter

Jeffrey,
as Eric already said, it's not yet in any released 1.x version. We've added that
HSRP block ourselves into our local netdisco installation.
