Rescue mode

The rescue mode system is a minimal operating system booted on demand over the network.

Currently we offer 3 different types of rescue mode:

If your server does not boot and you need to modify some files to fix the issue, the rescue mode will allow you repair it.

If your Dedibox server:

  • Does not boot following a reboot (no ping, following to a FSCK error for example)
  • Boots, but is not reachable because of a misconfiguration of the firewall
  • Does not boot after a kernel upgrade
  • Does not boot following to a modification of the bootloader configuration (Grub, lilo, …)
  • An update of the operating system
  • Any other issue that prevents your server being from being available on the Internet after the boot

In theses cases start your server in rescue mode so you can proceed to your maintenance. That operating system will permit you to access your server even if it's configuration is totally out of service.

How to launch rescue mode

Rescue mode is available in your management console, on the status page of a server by clicking on the “rescue” button

Attention Make sure you choose the rescue mode that correspondents to the OS you have installed on the server
(OS in 32 or 64bits, Linux, FreeBSD or Windows)

Linux/FreeBSD rescue mode

To connect to your server booted in rescue mode Linux/FreeBSD:

  • Use SSH on the IP address of your server
  • In case of security warning due to SSH identification, validate
  • After the launch, use the login and password given on the status page of the server. Please keep in mind, that the rescue mode usually needs about two minutes to initialize.

Once you're in the system you can use it like a normal distribution.
The installation of your favorite tools, like text editors or FTP clients is possible.
The single limitation is the size of the ramdisk.

Windows rescue mode

The rescue mode for the Windows users is a Microsoft Windows PE system.

The only way to access it, is by using the KVM/IP of your server.
