MyWorkspace
A newer service by Wageningen UR, this will soon provide you with the ability to have a remote machine at your will, connectable via an HTML5-compatible browser or a standalone client.
Using the VDI's with a browser
Go to https://workspace.wur.nl and select 'HTML Access', then log in. You should now be presented with a list of desktops and applications that can be run directly in your browser, no client installation required.
Depending on environment, there may be some caveats with using this - typically special keys (e.g. Ctrl) are difficult to transmit to the remote desktop, and may require the use of a full client.
Client Installation
First, you need to go get the correct client from VMware. Navigate to https://my.vmware.com/web/vmware/downloads and search for 'Horizon Client' - the latest version should provide a 64 and 32 bit Linux 'bundle'.
Download this .bundle file - it's just a bash script wrapping around a binary blob - and then set it executable and run it:
chmod +x VMware-Horizon-Client-*.bundle sudo ./VMware-Horizon-Client-*.bundle
Unfortunately this installer requires root to install its components - nothing you can do about that, as it wants to install USB redirection modules. You'll also need to accept VMware's EULA. Don't scan anything or register - that's not required for functionality.
