 ====== VNC Virtual Network Computing======
-These directions are for remotely connecting to a Linux computer using a VNC server. Must have a good internet connection in order for it to not be extremely slow, but note that the school's VPN may be the issue if connection is really slow. You should be using either TigerVNC or RealVNC, which include the VNC Viewer and the VNC Server.
+These directions are related to enabling you to remotely connecting to a Linux computer (i.e. Aircraft or Littlestorm) using a VNC client. You should have a good internet connection in order for the session to not be extremely slow. Additionally, you likely need to use the UND VPN to enable network access. You should be using either use TigerVNC or RealVNC clients, which include the VNC Viewer and the VNC Server; however, to access the Linux VNC server, you will need to run the VNC Viewer (client) locally. Users are able to start and top their own VNC servers on Littlestorm. To reduce memory usage on Littlestorm, user should run the XFCE4 Desktop environment on Littlestorm, instead of the default gnome desktop environment. You will need to start the XFCE4 desktop via the xstartup file using the command 'exec /usr/bin/xfce4-session', see next section for details.

     - A secure shell (ssh) client is required. On Windows, use [[https://atmoswiki.azurewebsites.net/doku.php?id=atmos:citation:soft:putty_ssh|PuTTY]].
   - The UND VPN is also required. [[https://und.teamdynamix.com/TDClient/2048/IT/KB/ArticleDet?ID=145487|UNDvpnInstructions]]

+      - When logging into the vpn, use should be able to use vpn.und.edu; however, if you have issues you can try vpn.ndus.edu instead of vpn.und.edu.
   - Login to PuTTY with your NDUS login. (firstname.lastname, ndus password)
