What will happen if you lose your password for “root”,since “root” is the God of LINUX ?You will never get it back but you can reset the password easily. For that, you have to boot in single user mode,it depends on your boot loader.

1. Grub : Select the Linux system you want from the graphical menu and then press ‘e’,you will find yourself in a mini editor,there you can make changes in boot commands.Move the cursor to end of the boot command line,add a space there and either a “1″ or word “single”.Then enter press Enter and ‘ b’ to boot this line.
2. Lilo : Hit any key but Enter at the boot menu.If that take to a command prompt type linux single and press Enter boot system again.

Now your password is set to blank which is dangerous so don’t forget to reset it again.

I have tested it with Linux versions like Redhat ,Fedora core and Knopix.But many new versions like SUSE wont let you start with out providing root password, for more details .

Run levels :Run levels will define what services or processes should be running on the system.The ‘ init ‘ process will take you to any of the run levels.System will run in any of the 8 run levels at a time.Among this 8 we are using only 0-6.When it enters level 0 it halts and reboot on enters on 6.Other levels 1-5 differ in terms which drives are mounted or which network services are started.Different run levels can be listed as

0 – Halt : is the system halt or power off automatically when it reaches the run level 0.But old version computer will powered on showing a message system is on HALT state.

1 – Single-user mode :It is also known as ‘rescue’ or trouble-shooting mode,no daemons are started here.You can boot in to this rescue mode by using your boot loaders like Grub or Lilo.

2 – Not used(user definable)

3 -full multi-user mode

4 -Not used(user definable)

5 – Full multi-user mode (with an X-based login screen)

Run levels 2-5 are full multi user mode.To use text console normally using level 3 and for using graphical interface level is set to 5.

6- Reboot : is used for system rebooting , once you set this and reboot your system you will be having two ways to change the setting .One is using a Live CD and mounting Linux partition on it ,reset the run level.Or else if you are using Grub as your boot loader you will have an option to set the run level as one.

Where this run levels live?

Run levels are defined in file systems.All these file systems are seen in a directory /etc. Each run level is actually, a set of programs that will be run.Run level 3 will have a certain set of programs. Run level 4 will have another set. of programs.names of these programs will be present in /etc/rc0.d/ rc1.d/ rc2.d/ rc3.d/ rc4.d/ rc5.d/ rc6.d/ folders,that is if add a link to a new program (some a.out for example), in rc4.d folder, it’ll be run automatically when you switch to run level 4.

The Init Program :the init process reads the file “/etc/inittab” and thus creates the process according to the run levels.This help a user to set the run level manually by

$ init 5 which will jump to level 5

For checking the current run levels ,on most systems users can check the current run level with either of the following commands:

$ runlevel

$ who -r

Both of these are well known commands for getting privileges of a super user. Now, how does they differ from each other?

1. sudo : In case if a server needs to administered by a large number of users and you need permissions of root for a while ,it is not possible to give permission for all, you can use “sudo“,where you will have the permission for a short time in a restricted way ,means the sudo utility allows users defined in the /etc/sudoers configuration file to have temporary access to run commands they would not normally be able to due to file permission restrictions.You just have to type your password for getting access.

2. su : Becoming root for a complete Login Session if you know the password of root ,”su” will do it for you. su will help you become root from your user login.It allows users to switch the terminal to a different account by entering the username and password of that account. If no user name is given, by default it will become “root” , thus providing a fast method to obtain a login shell with full privileges to the system. Issuing an exit or logout command returns the user to their own account.

Few days back I made a post where I was cribbing about the fact that everyone is teaching on how to fight against plagiarists but still things were unclear.

But, I would like to say a big thank to Jonathan who suggested me to send the DMCA letter and in case you’ve got any such problem then feel free to access the pre-formatted DMCA notices provided by Jonathan at his Plagiarism Today blog.

Thanks a ton Jonathan for provided such useful information on such an important topic!

The effect of that post was that GoDaddy canceled the account and the blog which copied the content got offline but then after couple of days, I got an email from the owner of the account whose name is Wong and found out that he was away on holidays and so had handed over the blog to his friends, and they were copying and pasting all the posts.

I would like to thank Wong because he respectfully removed all the posts which were copied and apologized for a mistake which he didn’t make. Thanks a lot Wong for the support which you’ve shown.

Be careful next time and happy blogging to everyone!!!
