Hello Damien,
of course, the tnewpass was my copy error - newpass is OK and is in
config files everywhere.
And the carp interfaces' advskew, vhid and
pass are already in /etc/rc.conf.local.
What I simply would like to try is run scripts if carp interfaces change.
Actually my real aim is to synchronize file from slave server to
master if master reboots or slave becomes master due to carp problems
on the master.
Regards,
Peter
