SSH (Secure Shell) communication protocol is natively installed on all OVHcloud servers (VPS, dedicated servers, Public Cloud instances).
Learn how to use the SSH service to access your server.
Many software applications enable you to connect via SSH. To help you, here are some examples.
For the latest Windows 10 and Windows Server versions, developer mode gives you access to a bash console. Here is a link to the Microsoft documentation: https://docs.microsoft.com/fr-fr/windows/wsl/install-win10.
Terminal
tool is delivered with Mac OS X, and is systematically installed on the machine.Console
or Terminal
tool is natively installed, and can be used to connect.Terminator
terminal emulator can be installed. You can read an Ubuntu manual page for Terminator here: http://manpages.ubuntu.com/manpages/zesty/man1/terminator.1.html.To connect to your machine via SSH, you will need two details:
You can connect using the following command:
ssh root@server_IP
Or this:
ssh root@server_name
The following message will appear:
The authenticity of host servername (server_IP) can’t be established.
RSA key fingerprint is a9:bb:55:35:86:xx:xx:00:xx:00:2b:2c:79:10:96:3c.
Are you sure you want to continue connecting (yes/no)? YES
[!warning] Permanently added servername, server_IP (RSA) to the list of known hosts.
Password:
root@vps12345:~#
When you first connect, your SSH client will receive an RSA key fingerprint, which is a fingerprint of the server you are connecting to. This is verified for each new connection. If the fingerprint changes, you will be informed, and this will mean something has changed:
When you first connect, you must accept the fingerprint that will be saved onto your desktop by your SSH client.
On Linux distributions, you will have access to a manual with all of the commands available, and their arguments.
man bash
Both your SSH client and your distribution must be kept up-to-date. You can check this with the following command:
ssh -V
If you have any doubts, please refer to the documentation for the SSH client you are using.
