>Description:
I have recently setup a jail on 6.0-STABLE. When reviewing the daily periodic emails "security run output" and "daily run output" it contained the following:

ipfw: socket: Operation not permitted
ip6fw: socket: Protocol not supported

Network interface status:
netstat: kvm not available
ifnet: symbol not defined

I think it might be worth mentioning in the manpage when setting up a jail to add the following to /etc/periodic.conf:

daily_status_network_enable="NO"
daily_status_security_ipfwdenied_enable="NO"
daily_status_security_ipfdenied_enable="NO"
daily_status_security_pfdenied_enable="NO"
daily_status_security_ipfwlimit_enable="NO"
daily_status_security_ip6fwdenied_enable="NO"
daily_status_security_ipf6denied_enable="NO"
daily_status_security_ip6fwlimit_enable="NO"

This will stop the tests that are trying to run commands that aren't valid inside of a jail because they don't have access to those resources.

>How-To-Repeat:
Setup a full blown jail. Let it run over night. Examine the output of the periodic emails.
>Fix:
see above
