Hi,
I need to remove the ability for people to use Yahoo Messenger. The easiest way is to add rules to the firewall to block the ports it communicates on.
Does anyone have a list of ports it uses. A list of IP's would be usefull as well to stop people using proxies to get around the block.
Thanks

1 edit | Yahoo! IM uses port 5050, 80, then any. But, the user can change this at any time.
Here are some commonly used servers of Yahoo:
cs.yahoo.com
scsa.yahoo.com
scs.yahoo.com
You could also try using these IP addresses, listed here.

Marysville, CA | What OS are the end user using? You can give them end user rights. Meening they cannot install anything what so ever.
Where I work, they give most of the users end user rights and block the web site.
