WWW::Shorten::Smallr on CPAN - Initial Release
I've just uploaded the initial release of WWW::Shorten::Smallr
to CPAN and it should be making its way through the mirrors right about
now.
The module itself is simple, it shrinks the given URL using the http://smallr.com/ web site. I wrote this for two reasons, firstly smallr is the official link shortener of one of the mailing lists I frequent and I wanted it available from the Vim Shortener I wrote. Secondly I wanted to have another play around with Module::Build. Which I understand slightly better now.

Open Ports Nagios Check
A machine should run a defined set of ports, if any of them are not
listening you've got a problem. If any others are open then you've
potentially got an even bigger problem. The Check Open
Ports Nagios Check accepts a list of IPv4 TCP and UDP ports and
reports if any of the expected ones go away or any others are detected
as listening.
This also partially scratches one of my own itches, I've had a couple of daemons (MySQL in particular) start after a package upgrade without my knowing it. With this script and a little cron it won't happen again. It's probably worth mentioning that while this script is built to run within Nagios it will work stand-alone.
Note: this script is more for detecting misconfigurations than for
security. Most root kits mask the ports they've opened so they won't appear
through netstat, which this command uses.
