Trigger action on link state change
Hi all, i was wondering if there is any ready-made method to trigger an action as soon as a link changes state. Along the lines of onifdown_em0=/run/this/script in rc.conf Background: Discussing physical data security with a client yesterday: The machine has to run 24/7. The filesystem is encrypted on boot, but this doesn't help a lot if anybody brings an AC generator to steal the machine *AND* the UPS. Best point in time to lock the machine I could think of was when somebody pulls the NIC cable.

We actually use it in production to send nagios passive alerts on CARP status change and LAGG interface loss of fault tolerance. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
