4.3 Connecting to the Cloud Server via SSH

SSH (Secure SHell) is a network protocol that allows you to connect to a remote computer (like your Cloud Server) via command-line interface.

SSH uses a cryptography system both for the authentication and for the work session and this is why it is preferred compared to other protocols and has in fact become the standard in remote administration of Unix / Linux systems.

Connect to the Linux Cloud Server from a computer with Linux Operating System

To connect to the Linux Cloud Server from a computer with Linux Operating System simply use the SSH command

ssh 192.168.123.253 -l root

(where the IP is the IP of the Cloud Server; by pressing the enter key you will be requested the password of the Cloud Server)

Once the authentication has been made it will be possible to perform all the SSH commands to run your Linux Cloud Server.

Connect to the Linux Cloud Server from a computer with Windows Operating System

To connect to the Linux Cloud Server from a computer with Windows Operating System, you can use various clients that allow access via SSH: among the most popular is the OpenSSH, WinSCP, and above all PuTTY.
We shall use the latter to provide an example.
  1. After running PuTTY, in "Session" you need to configure the "host name/IP address" with the Public IP associated to the Cloud Server.
  2. Then by clicking on "Open", a window will open with command-line interface where the login is requested which in this case is "root".
  3. The password for the "root" user will then be requested which is the same password of the Cloud Server (the one selected when creating the Cloud Server).
  4. Once the authentication has been made it will be possible to perform all the SSH commands to run your Linux Cloud Server.
