My apologies if this has already been addressed, but I couldn't find
it in the man pages or mailing list archives.
Is there a way to enable logging of network interface state changes on
OpenBSD 4.3 or 4.4? This is mostly for forensic purposes - obviously
I'll know if my firewall loses its ethernet connection, but if
something starts flapping I'd like to be able to see it in my logs
rather than trying to catch it in the act.
My hosts are using mostly vic and vr drivers, and neither seems to
care whether the debug option is enabled.
Thanks for the help. dmesg for one of my Soekris (vr) boxes below.
