SSHClient

SSHClient is a command-line utility used to connect to remote servers using the Secure Shell (SSH) protocol. It is part of the OpenSSH suite, which is a set of free and open-source tools for secure remote login and other network services over an unsecured network. SSHClient allows users to execute commands on remote machines, transfer files, and manage network services securely.

The SSHClient utility is typically invoked from the command line with the command "ssh". It requires the hostname or IP address of the remote server and the username to log in. For example, to connect to a server with the hostname "example.com" as the user "john", one would use the command "ssh [email protected]". Upon execution, SSHClient will prompt for the user's password or use an SSH key for authentication.

Once connected, users can execute commands on the remote server as if they were working on a local machine. SSHClient supports various options and flags to customize the connection, such as specifying a different port, enabling X11 forwarding, or using a different identity file for authentication.

SSHClient is widely used in system administration, software development, and network management due to its secure and efficient nature. It is available on various operating systems, including Linux, macOS, and Windows, making it a versatile tool for remote access and management.
