OK Sir, I got you now!!!

yeah,
1. I tried typing in "passwd" but failed!!
2. I tried typing in "/usr/bin/passwd root", but I failed!!!!
3. It is not A\allowing me to save that file or write that file instead!!!


whatta do?

well, post creator, very first thing please give appropriate title for your posts like "unable to recover password(rhel6.0)" which can help readers to understand nature of your problem. Second thing Please try to provide more details, like operations system vendor version etc. Nobody can help you without complete information. Solution for your problem is to disable selinux before you change your root password, use this command when you switch over to single user mode # setenforce 0 only after this you can reset your root password in rhel6.

Thank you
Pushkar

Again, spell out your words...."whatta do"...really??

And saying "but failed!" tells us NOTHING. WHAT HAPPENED? What did the screen say? What were the results?? Again, you need to either boot from CD/DVD, and reset the password from there, or you need to boot to single-user mode by typing in an "S" in the Grub menu. If you're already in single-user mode, you reset the password from there.

And are you running a 'real' machine or a virtual machine? If it's virtual, then selinux will come into play.

... and drop the exclamation marks; that's the equivalent of shouting.

OK SIR.

I will Keep all these Suggestions in Mind, while I make Posts later. This was the first post by me, so didn't know the rules to be followed .

And Thank you for the replies. I learnt a lot , and let me check if my problem gets solved by disabling Selinux

Thank You Sir . You solved my problem. After I disabled Selinux, I could reset "root's" password by command "passwd root".

Thanks a tonne!!!

This is a bug in SElinux policy version. You can still disable the SE Linux and try running the command. That will work.

Try running "setenforce 0"

or edit /etc/selinux/config

set "SELINUX=disabled" and reboot
