Piyush ... 1. Tools : -YM with their YM ID :-) ... but they can be in invicible mode .. :-( - Make simple HTML Pake with ... YM status on it [ just like the one on the YM website .... again they can be invicible :-( 2. Network SNiffer Will DO ....however there are several connection type in YM .... one of them .." Firewall with no proxies " cannot use Network sniffer since the packet is encrypted.
3. Block Connection to YM Server .... such as scsb.yahoo.com , there are others you can see when the YM try to make connection [ this method cannot be done if the YM is using proxy ... :-) , you should block access to proxy also ] Blocking using port number is not effective since YM use several well known port such as : 80 , 81, 25, 110, 8080 , .... Damn .. this YM is CLEVER ... :-)) HTH ..
