SSH, or Secure Shell, is a network communication protocol that allows two computers or devices to connect and share data securely. It provides a way to log into a remote server and access it without the need for a password, thus facilitating secure connections over potentially insecure networks. The process involves generating SSH keys, which are used for authentication purposes. Setting up SSH on a Linux server involves configuring the necessary settings to enable the connection. This allows users to manage their servers remotely, enhancing efficiency and security in data transmission. Overall, SSH is an essential tool for users needing to interact with remote systems in a secure manner.
