Hello all,
This is my first post to OpenBSD mailing lists. I'm a network and system
engineer in a small French web hosting company.
I've set up two OpenBSD boxes to act as redundant firewalls in front of
our network and I experience a strange behavior :
After a couple of hours/days one of the box stop functioning properly :
no ping, no more SSH access but I still capture CARP avertisement on the
network segments (when it occurs on the master). As a result, when it
happens on the master, the slave does not take over.
When it happens on the slave, the switch "sees" intermittently the
virtual CARP mac on the slave port so it disturb the master routing
operations.
When I hook up a screen on the machine, I get back the login screen but
everything is frozen.
I really don't know where I should start looking at to troubleshoot the
issue.
Here's the dmesg, the two boxes are identical. I do VLAN routing on em0
and pfsync on re0 (@ 100BaseFD to be sure there's no issue with the
re(4) driver) :
