Welcome to the ssh ubuntu guide

Installing SSH on Linux:

Check to see if ssh is installed


                sudo apt list --installed | grep "ssh"

If the command outputs a lot of packages then I would suggest executing the command below

If the terminal outputs nothing then it is not installed and you must manually installed it like so:

Installing SSH


                sudo apt-get install openssh-server

If that command does not work, meaning it does not install that package on your system, then you can proceed to creating ssh keys Or to be on the safe side, you can execute the command below to see all the ssh packages

Searching for SSH packages

 
                sudo apt cache search ssh

SSH into a client or server

You can ssh into clients and other terminals as long as you have their IP address and their port is open which is port 80. The general syntax would be this:


                ssh [username]@[server IP]
