| Beschreibung: In this tutorial I will explain how you can control or completelyblock access to a few instant messengers with SafeSquid, like GoogleTalk, Google chat within Gmail, MSNMessenger, Yahoo Messenger and Skype. Once you are familiar with themethod of blocking these messengers, you should be able to block othermessengers. Please note that thesemethods will only be effective, if you block all direct access to therouter and firewall, except required ports like 25 & 110, so thatusers are able to access the net onlythrough the proxy server. When all higher ports are blocked, mostmessenger try to communicate on port 80 and 443, which will have to gothrough the proxy, and thus allow you tocontrol them. Most messengers also allow you to define proxy settingsand username / password for authenticating Proxies. | |
