[iniaa]

Hi,
I'm having a problem in reset my root password. Somebody have change the password in our server. I have following below instruction:

1.Select Red Hat Linux with the version of the kernel that you wish to boot and type e for edit. You will be presented with a list of items in the configuration file for the title you just selected.

2.Select the line that starts with kernel and type e to edit the line.

3.Go to the end of the line and type single as a separate word (press the [Spacebar] and then type single). Press [Enter] to exit edit mode.

4.Back at the GRUB screen, type b to boot into single user mode.

After this instruction, it ask me to enter maintenance password but I don't have it. Can anybody help me on this problem?

Thank you in advance.

Hello and welcome!

Try the following HowTo and see if it works for you:

If all else fails, you can boot with a liveCD and change it.

Hi there!

FWIW, I've used the method involving the LiveCD before. Works quite nicely.

FWIW, I've used the method involving the LiveCD before. Works quite nicely.

Just remember, if you do that, then after you login to a command line as root in the LiveCD/DVD environment, you need to mount the original file system and chroot to that. Then you can run the passwd command and it will change the system's root password for you.

Caveate: this is a good illustration that if you have physical access to a machine, then you can own it!
