If we are doing like that(Previous Post) , There is no security for our system.For that we have to disable the grub options

Do the following It is very interesting,

In Terminal(should be a root user)

#grub

It it will entered into sub terminal

grub>md5crypt

password: <type Password>

Encrypted: <Encrypted Password>

Description: In the above command we are applying the md5(Message-Digest algorithm 5) for encrypt the given password

… continue reading this entry.

In many cases there is a chance to forgot our Username or  password. For that we have to reinstall the Operating System.Do the following funny things for setting a new password for Your Machine.

If you are the debian distro user

1–>Reboot the system.

2–>While Starting,Select the OS Which you have to reset the password and press ‘e’ select the second line which is started with kernel key word and press ‘e’ to edit the current line.

3–> Append the line with rw init=/bin/bash and press ‘b’ to boot the system

4–> Then it will entered into the root terminal

5–> To list the available users use the command

#ls /home

6–>To set the new password

#passwd <user name>

7–>The main thing is you have to set the password with only one character. After you are entered into the x session then you can change the password whatever you want.(The typing characters should not be displayed)

8–> Reboot the system

Enjoy….

If you are Fedora Distro user

The above steps are same except the step3. Instead of using rw init=/bin/bash just put 1

“Here no restrictions like invisible of the characters and the password length should be one character”

Hi friends, Sorry for the delay in the update because i am busy with my first Internal Test in our College…The good news is I have passed all the exams…. Ok Lets come to the topic

In Debian distro’s we can easily login as root by setting login Window

go to System->administration->LoginWindow

and click the option security and mark the check box

“Allow local system administration” then you can easily login as root in Debian Distro’s

In fedora there is no login Window option, However it is possible to login as root

in terminal to root login

$su

$gedit /etc/pam.d/gdm

in the above file put the # at the starting point of the second line(shown below)

#auth       required    pam_succeed_if.so user != root quiet

and also the same thing to the another file

$gedit /etc/pam.d/gdm.password

The second line change to like that (ie put # infront of the second line)

#auth        required      pam_succeed_if.so user != root quiet

now you can easily login as root

Cheers….

1.If you are executing a application  in terminal then the terminal becomes free when you closed the opened application.. Howewer it is also possible to run more than one applications in the same terminal itself.. It is simply by Putting & at the end of the command…

2.Assume you are in the following path in terminal

/media/DATA/folder/filename

but you have come  home directory so you execute the command cd ,unfortunately you again want the previously excuted path that is  /media/DATA/folder/ it is simple to retrieve by the following command

cd -
