Make Any Printer AirPrint-compatible on FreeBSD

When fail2ban just won’t match… check the time and time zone.
I was trying to set up a fail2ban jail for wordpress inside a FreeBSD jail, but I just couldn’t get the rules to match. The fail2ban instance was running on the host machine, checking a log inside the jail. Turns out the time zone in the jail was incorrect, and fail2ban was not matching log …

Often times, in your Squid proxy, you may have a redirector configured – such as SquidGuard:

redirect_program /usr/local/bin/squidGuard -c /usr/local/etc/squid/squidGuard.conf |
I ran into a problem tonight with my Roku box where SquidGuard was seeing Roku’s NetFlix access as a security threat. So, to make Squid bypass the redirector, add an ACL and a redirector-access rule:
