 Once connected to the server, you will be presented with a Linux command line.  If unfamiliar with the Linux environment, here is a link to a [[https://ubuntu.com/tutorials/command-line-for-beginners|quick guide]] that covers the basics of Linux shell operation.
+To use Key access, refer to the following page: [[access:sshkeys| Using SSH Keys]]
 ==== Private servers ====
 Some CIM computers are on a private (internal) McGill vlan (10.69.54.0/23).  These servers cannot be accessed directly from the internet.  To access these computers, you can use the McGill vpn to get on the McGill network, or you can use any public CIM server as an ssh jump host.  (SSH jump hosts are a way to proxy ssh connections through one server to access another)

 The command to connect to a private CIM computer is:
 <code>
-ssh -j <CIMUSERNAME>@barn.cim.mcgill.ca <CIMUSERNAME>@<PRIVATESERVER>.cim.mcgill.ca
+ssh -J <CIMUSERNAME>@barn.cim.mcgill.ca <CIMUSERNAME>@<PRIVATESERVER>.cim.mcgill.ca
 </code>

 ==== PuTTY ====
-If you are on another type of operating system, we suggest using an ssh client such as [[https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html|PuTTY]] to connect to CIM computers.
+The Windows commandline now includes an SSH client, but if you routinely log into a remote system from your Windows machine we recommend using an SSH client such as[[https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html|PuTTY]] to connect to CIM computers.
 When you open PuTTY, you'll be presented with a configuration screen where only two options need to be configured, the server address (barn.cim.mcgill.ca) and the connection type (SSH).

 === Private servers ===
 To access private CIM servers, you'll need to configure an SSH proxy in PuTTY.  To do so, you'll need a version of putty >0.77 and navigate to ''Connection > Proxy'' and select SSH as the proxy type and specify the details of the jump host (barn.cim.mcgill.ca).
+==== X2GO ====
+For remote desktop access to CIM servers, you can use x2go. (most CIM servers should be setup for it, but please contact us if a machine does not have the x2go server installed)
+To use x2go, you will need the x2go client install on your local machine.  You can download the client from the [[https://wiki.x2go.org/doku.php/download%3Astart|x2go website]], or if you are on a linux machine, there should be a x2goclient package available.  For example, on debian-based systems, the following will install the client:
+<code>
+# sudo apt-get install x2goclient
+</code>
+Once the client is installed, you can configure the connection with the following settings: (change the login to your username and the host from barbados.cim.mcgill.ca to the machine you want to connect to)
+{{ ::x2go.png?direct&400 |}}
+Once the connection is configured, you should be able to connect and use the remote desktop.
+{{ ::x2go2.png?nolink&400 |}}
+If you need to use the GPU for graphical applications, the configuration is more involved and will require intervention from us to set the server up to allow it.
