Ubuntu SSH: How to use SSH on Linux distribution

SSH is a tool that connects to another device over a network. SSH stands for secure shell (secure console). An SSH is often used to connect to and configure a Linux server.

How to open SSH on Ubuntu

Secure Shell is on one hand a network protocol and on the other hand the software needed to open a shell. To be able to connect, an SSH server runs on the external computer and you start an SSH client that connects to this server.

1. With an SHH connection you can control another PC completely encrypted. This is useful if you want to connect to a computer in the office, or to a server that is located in a server farm.
2. You can also connect to a NAS or a Raspberry Pi.
3. A SHH connection is very easy to establish in the process. Open a terminal by pressing "Ctrl" + "T".
4. Assuming the PC you want to connect to can be reached at IP 192.168.0.1 and has a user named "admin".
5. Then enter the command "sudo ssh [email protected]" into the terminal. After that, you will be asked to confirm the connection with a "yes".
6. Once the connection is established, you will be asked for the password of the user "admin".
7. Now you are connected to the PC or server and can transmit commands through the shell.
8. Once you enter the command "exit", the shell will be closed and you will be back in your own terminal.

An SHH connection can also be established using a key. To do this, share an SSH key with the server.
