Purpose of the dedicated server recovery mode
Recovery mode can be used in case of a critical system failure which prevents your server from functioning, or having access to it, such as:
- Bad kernel update
- Broken file system
- Lost root password or RSA key
- Misconfigured network interface or firewall
- And other issues
How to access the rescue mode
You can use the "Server Recovery" option in your dedicated server management page to load up System Rescue live image, which allows you to use a number of tools to help you fix various issues.
- In order to do this, open the server management page (from under Instant or Custom dedicated servers, whichever server type you are using).
- Open the "server recovery" tab on the left navigation panel.
- Enter a temporary root password and press "Submit"
After 5-10 minutes you will be able to log in-to the Rescue image loaded onto your Dedicated server via ssh.
Connect to your: ssh root@255.255.255.255 (replace the IP with the main IP of your dedicated server).
You might need to remove your current host fingerprint.
Use the password that you provided previously.
