[naruto143]

Anybody how to gain root password in ubuntu version 6.06
bcoz I can't edit my other files with root permissions and I also disable my the sudoers and I also lock my grub...
plz help me.........

[devils casper]

how did you do all that?
boot up from Ubuntu LiveCD, remove lock from menu.lst file.
boot up in single user mode and reset password with 'passwd' command. i am not sure if 'passwd' command will work in this situation, but worth to try.

what do mean single user mode
can you give me some steps to follow...

[devils casper]

in GRUB screen, select Ubuntu title and press 'e'. select 'kernel' line, press 'e' again and add <space> 1 at the end of line. press 'Enter' key and press 'b' to boot up. Ubuntu will boot up in Single User mode.

Alternatively, boot the live CD, mount any partitions that you have in relevent locations. eg: / partition to /mnt/ubuntu /home to /mnt/ubuntu/home

Then run:

chroot /mnt/ubuntu

Then

passwd root

and apply the new password.

This is one reason to secure your box so that the system CANNOT boot off CD!
