There are situations when you will need to access your Linux computer remotely. You can quickly configure Ubuntu to accept a Secure Shell Host (SSH) connection across a network or the Internet. Connecting via the SSH protocol will allow the user to administer the computer using Shell commands as though they were physically at the machine. Below I will explain how to install the OpenSSH Server and connect via the terminal.
Step 1 - Installation
The installation of the OpenSSH Server is a simple exercise and can be complete with one command. You do require the administrator password to complete this modification.
Once you have opened a new Terminal window paste the following command and press enter. You will then be asked to supply the administrator password. Then follow on screen commands.
$ sudo apt-get install openssh-server openssh-client
Once the command has finished executing you computer is now ready to accept SSH connections.
Step 2 - Connecting remotely
Below are two examples of the ssh command in the terminal to connect your Ubuntu machine remotely from another system. Type either of the following commands:
$ ssh your-server-ip-address
The following command allows you to specify the user account when connecting to your machine. This is neccessary for machines with more than one user account.
$ ssh user@your-server-ip-address
