Import an OVF into VMWare Fusion
First, install the OVF Tool. Then, run the tool. The syntax looks like this:

If you see errors about virtual hardware not being supported, you can add the –lax parameter to the command line.

Make Any Printer AirPrint-compatible on FreeBSD
AirPrint is a cool technology, but what if you have printers that aren’t officially supported? Here’s how to make it work. Note that this was done on FreeBSD 10.1. This may work on other operating systems, but package installation and filesystem paths will be different.
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 …

Python: Get XML Representation of an Object

The class in question is pretty basic: It has a constructor, member variables, getters and setters for the member variables, and now this new function. Every Python class has a built-in …
Squid: Bypass redirector for specific URL
Often times, in your Squid proxy, you may have a redirector configured – such as SquidGuard:
1 | 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:
