The rescue system is also known as the Rescue64-PRO system. Its is an linux Debian distribution which boots up the server from the network. The server OS will come from the network level and the physical drives connected on the server will be shown as external hard drives connected to the server itself.
Under this environment you can perform a number of task from resetting passwords, making backups and to resolving network issues on the server. To enable the rescue mode you need to modify the boot time under the control panel.
Once the rescue mode has been selected, you need to complete a reboot on the server to activate the rescue system on the server itself. The rescue system has the default SSH port enabled of 22. This will allow you SSH to the server, the username and password for the SSH rescue system is an one time password which is sent to your email address. Any subsequent reboots will generate a new rescue mode password.
The rescue system also allows for a graphical user interface. This will enable you to perform some hardware test to see if the hardware on the server is healthy. The URL to the graphical user interface of the rescue mode is found at:
On the left hand side you can check the health of the hard drives and see the partitions on right.
Here we can test the CPU and the RAM. Its not advisable to test the CPU and RAM at the same time as this can lead to the server to become non-responsive.
Bandwidth test can also be performed to see how much throughput the server can handle.
