Hi Mahesh, I have just recently done this, I found though that blocking the IP was no good as the IP's change (and could change).
The first thing you have to do is make sure that the users can't get directly out to the outside world (must use the proxy). Then I created and added the following lines in the squid.conf: acl MSN req_mime_type ^application/x-msn-messenger$ http_access deny MSN This identifies the MSN traffic and blocks it (works great, much to my users disgust *grin*). Justin >>> Mahesh P <[EMAIL PROTECTED]> 22/06/2003 5:59:28 pm >>> Hi there, I am running Redhat 7.3 with squid 2.4 stable i want to block MSN Messenger communication for this i have configured as below :- acl msn-mess dst ip address/subnet mask http_access deny msn-mess <for specific user> But it is not working. My user are using squid for running msn messenger they set in options through proxy port 3128 and they are successfully running msn messenger. is there any way i can block msn messenger in squid by using either port number or ip address? Thanks in Advanced Mahesh
