While compiling some earlier versions of bluez, which provides support for core bluetooth layers and protocols, I ran into a minor error. The error complained about no check being available. Read below to see the initial error when running ./configure and how to install the check package to resolve the errors. Installing the check package will fix this problem likely on any platform but for sure on Ubuntu 10.04 since Backtrack Linux is currently built on that platform.
Often times when I have Windows XP installations which will not boot one of the first things I will try is a check disk from the recovery console. This will often times fix Windows file problems which are preventing Windows from booting properly. In order to do this you will need a Windows XP installation disc.
Nagios is an awesome open source application that provides a way to monitor pretty much anything that you can think of on your network.

Follow the directions below to deploy a Perl script that will use SNMP to retrieve Linux server process size.
