Accessing Remote Applications

Cobalt can be integrated with VNC servers to allow participants in a Cobalt Space to share remote applications for:

  • Web browsing (Firefox)
  • Word processing (Open Office)
  • Spreadsheet creation (Open Office)
  • Presentations (Open Office)
  • Whiteboarding
  • Remote desktop manipulation
     

Launch Remote Applications from the OpenCobalt Project Servers


To launch the Firefox Web Browser

  1. Select Tools > Remote Web Browser.
  2. A pop-up window will ask you for the address (URL) of the web site you wish to visit (the default address is set to Google). Enter the URL (you must include the full address, beginning with "http://...")
  3. Click OK. A frame will appear in your space. It may take several seconds for the application to finish loading in the frame. 

To launch the OpenOffice Word Processor or the OpenOffice Spreadsheet Application

  1. Select Tools > Word Processor or Tools > Spreadsheet.
  2. A frame will appear in your space. It may take several seconds for the application to finish loading in the frame.

To launch the Open Cobalt Project's Remote Desktop

  1. Select Tools > Access Remote Desktop...
  2. A frame will appear in your space. It may take several seconds for the remote desktop to finish loading in the frame.

 Setting Up Your Own VNC Server

The Open Cobalt Project maintains VNC (remote application) servers for our project development work and to provide users with an opportunity to test Cobalt's remote application feature. However, we maintain very modest server capacity and cannot meet the server demands associated with many hundreds (or thousands) of concurrent users. To ensure robust performance your organization will most likely choose to set up its own server for delivering the applications you wish to share in your Cobalt spaces. For details on setting up a Xrfb remote applications server, please see xxxx. 

Xrfb Client Setup (if using your own VNC servers)


Configuring your client

Once you've set up a VNC server and configured your client you can launch remote applications within Cobalt. The applications available will be those your Systems Adminstrator loaded on your VNC server.

 The Cobalt client's remote application settings are by default configured to pull remote applications from the servers maintained by the Open Cobalt Project. To redirect your client to your own remote applications server, you must modify a few settings.

First, you'll need the address and the password for your Xrfb server, both of which should be obtainable from your Systems Administrator. Once you have this information you're ready to complete the setup:

  1. Select Cobalt > General Preferences.
  2. In the text box next to Xrfb Server Host Address enter your Xrfb server address.
  3. The Xrfb Server Port Number is set by default to 5899. In most cases, there should be no need to change this.
  4. In the text box next to Xrfb Server Host Address enter your Xrfb server password.
  5. Click Enter. Once you're finished you may close the General Preferences window.
