Good morning, I have configured squid -2.5.STABLE3-6 on Rh3 ES Squid is configured to use ntlm authentication To an Active Directoy Server in such to give internet access only to authenticated users,it works optimally all. I would know how to block a single user's internet access from different ip at the same time. Thanks in advance for any kind of support. Best regards Luca Forti System Network Administrator
