How to check SSH connection

SSH, or Secure Shell, is a cryptographic network protocol that enables secure communication over an unsecured network. It is commonly used for remote command-line access, secure login, and remote command execution. Additionally, any network service can be secured using SSH.

SSH provides a secure channel over an unsecured network through a client-server architecture, connecting an SSH client application to an SSH server. The protocol is defined in two major versions: SSH-1 and SSH-2. The standard TCP port for SSH is 22. While SSH is primarily used to access Unix-like operating systems, it is also compatible with Microsoft Windows. Notably, Windows 10 includes OpenSSH as its default SSH client and server.

SSH was developed as a secure alternative to Telnet and unsecured remote shell protocols like Berkeley rsh, rlogin, and rexec. Unlike these protocols, which transmit information — including passwords — in plaintext and are vulnerable to interception through packet analysis, SSH employs encryption to ensure the confidentiality and integrity of data over unsecured networks, such as the Internet.

You can create SSH credentials and add an SSH key in the Admin area => SSH credentials section. For detailed instructions on how to create SSH credentials on Roxy-WI, please refer to this article

To check the SSH connection, open Admin area => Servers, open the server's Actions menu and choose Check SSH.

A success notification confirms that Roxy-WI can connect with the credentials assigned to this server.

If the connection fails, read the error notification and verify the SSH address, port, credentials and network reachability before retrying.
