Subject: Root password change

if you're chrooted under /tmp (as it sounds from your email) you're out 
of luck, unless you have a way to escape the chroot due to a 
misconfiguration of that environment in the first place.

Easiest way to reset a lost UNIX password is boot from a "live CD" (eg: 
knoppix) .. mount the / partition of your hard drive (eg: mnt -t ext2 
/dev/hda1 /mnt) then do "chroot /mnt" and execute "passwd root" from in 
there.

Then exit the chroot, umount /mnt, and reboot.
