This is a question that comes up quite often when looking at Google Apps for Education:
How do I block students from adding gadgets in Sites in Google Apps?
The FAQ and Google Code Resources that answer this question makes it seem pretty simple, and it is, once you know the step by step instructions.
First of all there are 2 main options of blocking gadgets in sites or on iGoogle pages:
- Blacklist Gadgets One at a Time:
- I would only use this option for a domain that is for staff or adults only where I have a particular person complaining about a specific gadget
- I would use this option if you want to protect students from any possible inappropriate gadget
- In the box that appears add this URL
- Click OK and then Save the changes to the page
You can search by keyword (gadget name, category, or url) and find the gadget you would like to blacklist. Click Add to blacklist the gadget. It may take a few hours for the item to be blacklisted.
Option 2: Blacklist Everything and Whitelist Gadgets 1 by 1
Step 3: Unzip the file and put in in your C: drive root
Step 4: Open the cmd prompt (cmd.exe) and type cd c:\fsct
Step 5: Type "fsct shell" and enter the username and password of an administratior of the GAFE account
Step 6: Type: "setpublicgadgetdirfilter BLACK_LIST" and hit enter. You will get back a response that your site feed has been updated.
Step 7: Unblock your Domain Directory Gadget Manager (not sure if this has to be done, but just making sure it remains open) by typing: "addwhitelistedgadget http://google-feedserver.googlecode.com/svn/trunk/resources/gadgets/domain-gadget-directory-manager/spec.xml"
You have now blacklisted all gadgets and have a tool to whitelist back the ones you want students or staff to use.
You can search by keyword (gadget name, category, or url) and find the gadget you would like to whitelist. Click Add to whitelist the gadget. It may take a few hours for the item to be whitelisted.
