When you work in a desktop graphical user interface environment, most of the of the popular linux distributions these provide with a nice interface to change timezones and time format etc.

But when you work on a server or a console installation of any distribution, changing timezone can be tricky. All machines work with two clocks, one is the hardware clock and the other is called as operating system clock.

LAMP Stands for Linux Apache Mysql and PHP

L- Linux

A- Apache

M- Mysql

Let us try to understand how data recovery possible in any machine?

So what happens when you delete a file in Linux or any operating system out there?

When a file gets deleted the operating system never removes the data from the hard disk, it just removes the link to access that file, and keep that space as unused.But still the data of your file is there in that exact location where it was.

Ext2 Filesystem:

Remy Card designed ext2 filesystem for the first time. It is a very powerful linux filesystem. For a very long time ext2 was the default filesystem for many linux distributions. In ext2 filesystem data of a file is held in blocks which means that when a filesystem of ext2 type is made the block size is set and will be same for all the blocks holding different kind of data.

For example lets say that the block size of an ext2 filesystem is 1024 bytes then in that case suppose you try to save a file of 1025 bytes then that file will occupy 2 blocks.

And this means that we end up wasting a lot of space.

This post is mainly concentrated on tips and tools useful in our daily life;

There are so many tools which can makes our task easy are available in markets now a days and most of them are free and easily available on internet you can just find and download them by simple googling.

slashroot.in have tested all those tools and mentioned few of them here for public use and make the task easy.

Hi all...before getting into lsof command we need to remember the most important fact in Linux/Unix industry ie; "everything is a file". Even devices,sockets,all are files.

Now lsof stands for "List Open Files", which is used by unix like system to show all open files and processes that opened them. Thanks to Vic Abell who developed this tool for the first time.

If you are interested in understanding all aspects of processes in linux, then i will suggest to read the below article.

Wikipedia defines netcat as below.

"Netcat is a computer networking service for reading from and writing network connections using TCP or UDP."

if you are into system administration its necessary for you to understand what netcat is and what are the functionalities of netcat.

Netcat can be used as port scanner, a backdoor, a port redirector, a port listener and much more.

Netcat can even be used to port scan a machine!!!! yea thats true.
