Hi , I am now running squid with ncsa_auth. I have bound ip addresses to usernames. So users now can access Internet from their ips. Now I want a few users to prevent from accessing all the sites. But Instead, I want them to allow to access a few sites scuh as google.com,cnn.com, bbc.com. I want to limit in that way. I have wriiten below rules. But those users still can access all the sites. external_acl_type ip_user %SRC %LOGIN %DST /usr/lib/squid/ip_user_check -f /etc/squid/ip.conf acl ncsa_users proxy_auth REQUIRED acl ip_users external ip_user %SRC %LOGIN %DST http_access deny !ncsa_users http_access deny !ip_users http_access allow ip_users http_access allow ncsa_users my ip.conf file is like this. [root@worldnet squid]# cat /etc/squid/ip.conf 192.168.101.25 indunil .google.com .bbc.com .cnn.com 192.168.101.90 www90 Accoring to the above file, User indunil with ip address 192.168.101.25 has access to google.com,bbc.com and cnn.com. But the user indunil still has access to all the sites. How can I solve this? -- Thank you Indunil Jayasooriya -- Thank you Indunil Jayasooriya
