Hits: 4235

In this video we review the necessary steps to set up an Ubuntu server for a remote ssh connection and how to connect to it remotely. We look at 2 different methods of connecting remotely.  WSL (Windows Sub System For Linux) and Putty.  From a Linux host you can just launch the terminal.

The commands used in this setup are as follows:

On the host (Ubuntu server):

  1. sudo apt-get update
  2. sudo apt-get upgrade
  3. sudo apt-get install ssh

On the ssh client (In a terminal or WSL)

  1. ssh username@host (IP  or hostname)

If you are using putty the you will configure the GUI with at least the minimum settings seen below:

putty 

 You should now be at the login prompt and be able to log in as the primary user from your Ubuntu server. Using this method is fine in your in a LAN but if you are connecting to a server outside of your LAN, there are several other security steps you will want to take.
