A chroot on Unix operating systems is an operation that changes the apparent root directory for the current running process and its children. A program that is run in such a modified environment cannot name (and therefore normally not access) files outside the designated directory tree. The term “chroot” may refer to the chroot(2) system call or the chroot(8) wrapper program. The modified environment is called a “chroot jail”. From Wikipedia.

Why it is required? If you want to set up your Linux box as a web hosting server for its users, you may need to give SFTP access. But they can get access to whole system Linux tree, just for reading but still very unsecure. So it is mandatory to lock them in their home directory.

left 4 dead 2

Some days ago Left 4 Dead 2 has been released on Linux on Steam Gaming Platform.
The game was released on 2009 for many gaming platforms such as Xbox and Windows, but if like me you like to play games on your Linux box, this is a good opportunity to play one of the most famous FPS cooperative survival Zombie games.

In my opinion Playstation joypads are some of the best you can find around, probably Xbox are good too, but I’ve an unused playstation 2 and so I’ve choose to go in that direction.

And I must say that with a great surprise everything worked fine without too much problems !!
