What is SSH Ubuntu Server?
SSH Ubuntu server is a secure remote access tool that allows you to connect to your server and manage it using a command-line interface. It is designed to provide an encrypted connection between your local computer and the server, ensuring that all traffic is secure and protected from interception or eavesdropping.
SSH Ubuntu server is part of the Ubuntu operating system, which is a popular distribution of Linux that is widely used for servers and cloud computing. It is a free and open-source operating system, which means you can use it without paying any licensing fees.
The SSH protocol was originally developed as a replacement for Telnet, which was an insecure remote access tool that transmitted data in plain text. SSH uses encryption to protect the data being transmitted, making it much more secure than Telnet.
