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 BOINC software and check your client firewall to ensure that the 'BOINC client' 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

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 here is the FAQ that will help you obtain your proxy information.
How do I find out my proxy information?
Your proxy settings are available in your Web browser. In Internet Explorer, these are under [Tools][Internet Options...][Connections] then choose either [LAN Settings] or [Settings] for your dial-up options. If "Use Proxy" is checked, click on the [Advanced...] button to see your proxy settings.
You will need to take these settings and enter into the BOINC version of the World Community Grid software. Instructions for doing this are found in this FAQ
How do I configure the software to use a proxy?
The software can be configured to use a proxy in the following way:
The dialogue that opens has tabs that allow you to enter in your HTTP or SOCKS proxy information.
- Double click on the World Community Grid or BOINC 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'
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, then you will need to take the following additional steps:
Make sure you are on the latest version of the World Community Grid agent by following the directions in this FAQ.
If this doesn't resolve the issue, then you will 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:
You want to replace this with additional settings for your 'ntlm' or 'basic' proxy.
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:
Finally, in order to check that you are able to download work, please 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 file'
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.
- Select the 'projects' tab
- Select World Community Grid from the list
- Click on the 'Update' button.
- Go to the messages tab
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. Instructions on how to do this are available in this FAQ
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 by downloading this file and placing it into your BOINC installation directory (on Windows this is usually C:\Program Files\BOINC). You now need to double click on the World Community Grid icon in your system tray (bottom right hand corner of your computer screen, by the date and time), select "Advanced View", then on the menu across the top of page select "Advanced", and then "Read config". Now more information will be logged.
In the Advanced View of the agent, go to the 'Projects' tab, click on World Community Grid, and then select 'update'. Next go to the "Messages" tab. 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"
Take note of the following:
- 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
