Securing Linux by breaking it with Damn Vulnerable Linux:
Damn Vulnerable Linux (DVL) is everything a good Linux distribution isn't. Its developers have spent hours stuffing it with broken, ill-configured, outdated, and exploitable software that makes...

When it comes down to it, /proc is a filesystem. Although it does not represent any physical device, you can still mount it and unmount it as you please. It contains a multitude of valuable information regarding the processes you are running, as well as the hardware you have hooked up to your computer (although in recent years, /sys has been devised by the Kernel folks to represent the hardware hierarchy and export device information ). You can see which modules you have loaded, how long your system has been up, and the memory usage of processes on your system. In fact, every single process running has an entry, or directory, inside /proc. As you can see, /proc can be a very powerful asset. But before you can use it, you need to mount it.

This document will cover two quick ways for figuring out the numbers behind subnetting. The first way involves making a simple chart, the second way uses simple math that most people can do in their head, at least for smaller numbers. The first way is recommended for any exams, or times when you need to do a lot of subnetting quickly. The second way works best if you just need to know one or two examples, or to check your work from the chart.
