![]() For example, you can view and monitor server and application load, use it to make bulk changes to files, or use any other shell command the same way you would on a local machine. With SSH access and the correct permissions, you can completely control the remote host’s Operating System (OS) with commands and scripts run through the remote shell. SSH is a valuable tool for managing files and servers remotely, but its usefulness doesn’t stop there. After entering the password, if the user’s credentials are correct, the SSH session starts. The client and server exchange identifying information, and prompt for the password or public key. Using a command line based client like OpenSSH, users run SSH and request the connection using their username and the remote computer’s IP address and port: ssh _address -p 22 Finally, a new SSH session is established if the user’s credentials are correct. The remote server runs a daemon that monitors a specific port for incoming client connection requests. Next, users enter the remote machine’s IP address or hostname and port number along with user credentials such as username and password or public key. Using SSH starts with an SSH client like PuTTY (Windows) or OpenSSH (Linux systems) that communicates with the server. This extra layer of security keeps all data transfers private and encrypted. Secure File Transfer Protocol (SFTP) uses an SSH connection in combination with FTP to securely transfer files. SSH gives users the tools to manage servers effectively through a secure, remote connection. With the proper permissions, users can execute different commands on a remote host, including shell and bash scripts. You can use it to securely create backups, transfer files, and perform file operations like copying, pasting, or moving files on the server. SSH is an indispensable tool in web hosting, although you may need some technical knowledge to take advantage of all the command line interface’s capabilities.
