I'm having trouble downloading the software
Perhaps your Internet Explorer is configured to block installing downloads. Within Internet Explorer, click on Tools-> Internet Options -> Security -> Custom Level -> Downloads. Check to see that File downloads are enabled. There might be other settings which need to be enabled such as the ability to execute Javascript. Please also check to see if your network requires a proxy, click here for Proxy FAQs.

How do I configure the software to use a proxy?

The software can be configured to use a proxy in the following way:

  • Double click on the World Community Grid icon in the system tray
  • When it opens, if you see some text that says select 'Advanced View', then click on it
  • From the options on the top of the screen select 'Advanced' -> 'Options'

The dialogue that opens has tabs that allow you to enter in your HTTP or SOCKS proxy information.

I entered in my proxy information but I still cannot get work. How do I get it to work?

If after you enter your proxy information and you still see messages such as those displayed in the FAQ "How do I determine why I cannot connect to the World Community Grid servers?" above and you have checked and made sure that you are on the latest version of the World Community Grid software, then you will need to take the following additional steps:

You need to determine what type of proxy authentication you are using. To determine your proxy authentication please refer to this FAQ.

Once you have determined your proxy authentication, open windows explorer and go to C:\Program Files\BOINC. In this directory you will see a file called cc_config.xml. Assuming you are using windows, right mouse click on the this file and select 'Open With' and select 'Notepad'.

This will open a new window that will be populated with the contents of your cc_config.xml file. It will look something like the following:

<cc_config>
 <log_flags>
  <file_xfer_debug>1</file_xfer_debug>
  <http_debug>1</http_debug>
  <http_xfer_debug>1</http_xfer_debug>
  <proxy_debug>1</proxy_debug>
 </log_flags>
</cc_config>

You want to replace this with additional settings for your 'ntlm' or 'basic' proxy.

<cc_config>
 <log_flags>
  <file_xfer_debug>1</file_xfer_debug>
  <http_debug>1</http_debug>
  <http_xfer_debug>1</http_xfer_debug>
  <proxy_debug>1</proxy_debug>
 </log_flags>
 <options>
  <force_auth>xxxxx</force_auth>
 </options>
</cc_config>

Replace the above 'xxxxx' with either ntlm, basic or gss-negotiate based on what type of authentication you are using and save the file.

In order to make the software re-read the file do the following:

    Double click on the World Community Grid icon in the system tray
    When it opens, if you see some text that says 'Advanced View', then click on it
    From the options on the top of the screen select 'Advanced' -> 'Read config files'

Finally, in order to check that you are able to download work, please do the following:

    Select the 'projects' tab
    Select World Community Grid from the list
    Click on the 'Update' button.
    Go to the messages tab

If all is working correctly, then you will see that you are downloading work and you will start processing it. If this has not helped you, then you can seek further help in the forums or by contacting us through the contact us feature on our website.

How do I figure out what type of proxy authentication I am using?

First, make sure you are using the latest version of the software. 

Second, there are some types of proxies that need additional settings to work with World Community Grid. The first thing you need to do is to enable some additional logging for the client.  You can do this as follows:

  • Double click on the World Community Grid icon in the system tray
  • When it opens, if you see some text that says 'Advanced View', then click on it
  • Select 'Options' → 'Event Log Options'
  • In the window that opens, make sure that the following are checked (don't change any of the others):
    • file_xfer_debug
    • http_debug
    • http_xfer_debug
    • proxy_debug
  • Click 'Apply'
  • Click 'Save'

You now have the additional logging enable.  Next, we need to check to see what this logging is showing us:

  • In the Advanced View of the agent, go to the 'Projects' tab, click on World Community Grid, and then select 'update'. 
  • Select Tools → Event Log.  

You will see messages going by. The critical one to look for is the line that includes "Proxy-Authenticate" like the ones shown below. There will be one or more of these in a row. You are interested in the first one.

  • 07/04/2008 18:18:09||[http_debug] [ID#0] Received header from server: Proxy-Authenticate: Negotiate
  • 03/25/2008 12:24:54||[http_debug] [ID#0] Received header from server: Proxy-Authenticate: NTLM
  • 03/25/2008 12.24.54||[http_debug] [ID#0] Received header from server: Proxy-Authenticate: Basic realm="realmname"

Use these messagess to determine the type of proxy that you are using:

  • If the first line contains "Negotiate" then you are using gss-negotiate authentication
  • If the first line contains "NTLM" then you are using ntlm authentication
  • If the first line contains "Basic" then you are using basic authentication

How do I determine why I cannot connect to the World Community Grid servers?

To determine why you are not receiving or sending workunits to World Community Grid, make sure you are using the latest version of the World Community Grid software and check your client firewall to ensure that the 'World Community Grid' software reflects "permit all" or similar verbiage that your firewall software uses to reflect an approved program.

If you are on the latest version and your firewall is set to allow the BOINC client to communicate, then please double click on the World Community Grid or BOINC icon in your system tray. Select messages and see if you have any entries like the following:

09/10/2007 14.30.14|World Community Grid|[file_xfer] Started upload of file li349_00025_8_0
09/10/2007 14.30.15|World Community Grid|[file_xfer] Temporarily failed upload of li349_00025_8_0: http error

or

05/03/2008 11.55.14|World Community Grid|Sending scheduler request: Project initialization. Requesting 1 seconds of work, reporting 0 completed tasks
05/03/2008 11.55.19|World Community Grid|Scheduler request failed: Failure when receiving data from the peer

If you do, then you may need to set your proxy. Here is the FAQ that describes how to set your proxy. If you do not know your proxy information, contact your IT help desk.

The software installer keeps giving me an error and asks me to check my Proxy settings.

You need to be connected to the Internet at the start to have the agent connect to the server to get work. Check to see if you can get to some web page with your browser. If your Internet connection is working, it might be that you have a software firewall which is blocking access to the www.worldcommunitygrid.org site. If you have one, try turning it off temporarily and see what happens. If it starts working, then add the www.worldcommunitygrid.org address as a trusted site to your firewall.

I get "Cannot Connect to Server" messages when logging in. What's wrong?
First ensure that you have internet connection to other sites. There are several scenarios which may cause this error:
  • This error could be due to a physical disconnection between your machine and the Internet, whether at your machine or your ISP.
  • Alternatively, our server could be temporarily down for maintenance. We try to restrict our maintenance to non-peak hours in the US, which may be inconvenient for folks on other continents. From time-to-time, it is necessary to take the servers offline outside our scheduled maintenance periods. We apologize if this causes any inconvenience. We will endeavor to keep the service available at all times.
  • This may occur on some machines that do not recognize the network when they are first launched. Exiting and restarting the World Community Grid Software clears this up, and users are able to connect without error.
  • If you are using a proxy server, a personal or corporate firewall, or an Internet gateway router, be sure to configure your settings before logging in.
