next in thread | raw e-mail | index | archive | help
I have a machine which I just cvsup'd to the latest stable.
When the periodic daily run calls ipfw, this panics the machine.
I don't understand why ipfw is even being called there. I don't run
ipfw on this machine.=20
It appears that /etc/security calls it like "ipfw -a", yet whne I
run it from the command line like that, I just get an incorrect
usage messge.
Why is this called here?=20
Can anyone tell me why it causes the folowing panic?
