Password recovery
Once your Server started by netboot, log in to the SSH. Are those by default in the mail delivery of your Server. Then it is necessary to Mount the partitions so that they are accessible. Ex with a standard partitioning (orders will be to adapt to your case ) :
- It first creates the destination folder :
# mkdir /mnt/disk
- Then we go up the system this folder :
# Mount /dev/sda3 /mnt/disk
If you have a RAID system, the command will be :
# mount /dev/md1 /mnt/disk
- Once mounted partitions you must perform a 'change of root ' (chroot ) to simulate being on your system, via the command :
# chroot /mnt/disk /bin/bash
- Then, there is more to define a new password :
# passwd
This command will ask you to type 2 both on the new password. A first for initialization, the second for confirmation.
- Finally, exit the chroot and reboot the machine.
# exit
# reboot
After reboot, you can log in as root on your machine via the new password that you set.
