Can I use either of these to edit the passwd > file and correct the problem. If so, how. Probably either Knoppix or the Debian CD will work. With Knoppix, just boot from the CD, mount the partition on which is /etc, and edit the file. Commands used will be approximately (you will need to use the correct block device): # fdisk -l # mkdir /mnt/tmp # mount /dev/sda1 /mnt/tmp # nano /mnt/tmp/etc/passwd # umount /mnt/tmp # reboot
