To support the array of tools we wanted to have at Relearn this year, we've set up a local network and a local server to allow for outside internet connections but ensure some tools to function properly while on local networks. By the front door is a server called complex.local First form groups of three. One person login as the user relearn $ ssh relearn@complex.local passw is entrepot Then that person makes extra user accounts for the each of the three: $ sudo adduser username It will first ask you to give the password for the user relearn, its entrepot Then it will ask you to choose and confirm a password for the new user you made. Then each user we add to the permission group 'relearn' $ sudo usermod -a -G relearn $user where $user is the username you just made. Once everyone has a their own user account, you can log in to complex.local with it! $ssh username@complex.local On windows we need to install PuTTY in order to get unix shell download it from --> https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html once you install it enter in the Configuration box --> Host: 192.168.73.188 . Done!
