Problem

You have lost your root password (Linux) and want to know how to retrieve.

Request to Ikoula

If you're having trouble and want that Ikoula is in charge of the recovery. You can order a one-off intervention of recovery of root password for your Ikoula client interface :

  • Allez sur l'onglet Compte
  • Cliquez sur Acheter plus de services
  • Cliquez sur Interventions ponctuelles
  • Choisissez Reset mot de passe
  • Réglez votre commande dans Compte -> Balance
  • Contactez notre support technique à ikoula@ikoula.com depuis votre adresse de contact technique et indiquez le Server you wish to recover the password

Netboot

Si au contraire vous souhaitez vous en chargez vous-même, sachez qu'il n'est pas possible de le récupérer, il vous faudra le modifier en passant par une session Rescue System aussi nommée NETBOOT.

Netboot Server dedicated physics

We invite you to follow the FAQ Qu’est_ce_que_le_netboot_et_comment_le_lancer_? that will explain how to do this.

Netboot Server dedicated virtual (FLEX)

It depends on the host on which your Server is present. We invite you to follow the FAQ Netboot_sur_serveur flex that will explain how to do this.

The password recovery

Once your Server started by netboot, connect to it in ssh. Access is present by default in the e-mail delivery of your.{Template:Serveur}}. Then you must mount the partitions so that they are accessible. Ex with a standard partitioning (orders will be to adapt to your case) :

  • We first create the destination folder :
     # mkdir /mnt/disk
  • Then we go up the system in this folder :
     # mount /dev/sda3 /mnt/disk

If you have a RAID system, the command is : 

     # mount /dev/md1 /mnt/disk
  • Once you have mounted the partitions you must perform a 'root change ' (chroot) in order to simulate being on your system, via the command :
     # chroot /mnt/disk /bin/bash
  • Then, it remains more to set a new password :
    # passwd

This command will ask you to type 2 time 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.
