Block Msn Yahoo Through Squid

Post by x2oxen »

1) Install all messengers you can imagine - Yahoo! , MSN , AIM , ICQ and Trillian
2) Install packet sniffer like ethereal on workstation
3) now try running all messengers one at a time
4) now look for common signs on how to block them

For example AIM uses host login.oscar.aol.com
MSN Messenger uses MIME type containing "X-MSN-Messenger" string

Same applies to digital media players, spywares, viruses etc.

Never try to use these programs when they are blocked for common users.
