Unhappy problem with terminal


hi everyone! I'm using fedora-11. Initially while doing the terminal part it used to come like this- [software@localhost ~]$,,,, then i used to give the password and enter the root. Here my username is software. Then i changed the ownership from root to software, so that i don't have to give the password each time. BUT NOW when i am giving su and entering the password it is showing INCORRECT PASSWORD. I don't know what has happened. Can some one help me please??

we can't understand your problem...

you some how changed the root password and forgot tat i guess...

go to single usermode or rescue mode to reset the root password ...


for password less login i dont think you need to change the ownership but use this

Code:
passwd -d username
this will make user password less ...

To the OP: Have you already added yourself to /etc/sudoers? If so, you can easily use sudo to reconfigure the root password:

Code:
sudo passwd
However, if not, there's only one recourse left: Reinstall, because passwd -d on the root account will LOCK YOU OUT OF THE SYSTEM!

You could also, as soon as the computer turns on, press <Esc> to get to the GRUB boot menu and press 'e' to edit the default boot option. At the end of the string, type:

Code:
init=/bin/bash
This will get you to a root shell as soon as the computer loads, and then you can type

Code:
passwd
to change the password to what you had before.

As I said before, reboot, press <Esc> to get a GRUB menu, and then press 'e' to edit the boot options, appending 'init=/bin/bash' to the end of the string. This will get you to a root shell
right after the kernel loads, from which you can type:

Code:
passwd
and change the password to what you have for your standard account.

Also: If passwd tells you to enter a current password, just press 'Enter' to abort and type 'passwd -d' before continuing.

let me guess wat u r doing

You have root user and you say you know its password right?

Then you login as normal user say john in GUI when system starts and you are able to login successfully .. right?

then you open the terminal and do this

$su -

and the password you are providing is for root and it says password incorrect ...

is this the scenario???

do let us know


to add yourself to sudoers list do this
(as root you have to do this)
Code:
visudo
add this line for john to make add him to add to list of sudoers

Code:
 john  ALL=(ALL)   NOPASSWD: ALL

Hi Do this;

Restart your Linux system
Press ctrl+alt+f2
you will get black and white screen with login option there try to login as root
and put the password which you think you remember...
let us know if you can login...
also login as your normal user and let us know if you can login...
