Dear All, Recently I have installed FC9 and squid 3.0 STABLE 2.0 (Which has installed along with that). I was trying using NCSA authentication. After a day long try I was unable to setup NCSA auth. At the end through googeling I found that STABLE 2 has the bug in auth. I updated squid to 3.0 STABLE 7 Authentication is working fine, "deny all" is not working. When I add acl all src 0.0.0.0/0.0.0.0 it gives following error 2009/02/10 11:35:21| Processing Configuration File: /etc/squid/squid.conf (depth 0) 2009/02/10 11:35:21| WARNING: '0.0.0.0/0.0.0.0' is a subnetwork of '0.0.0.0/0.0.0.0' 2009/02/10 11:35:21| WARNING: because of this '0.0.0.0/0.0.0.0' is ignored to keep splay tree searching predictable 2009/02/10 11:35:21| WARNING: You should probably remove '0.0.0.0/0.0.0.0' from the ACL named 'all' 2009/02/10 11:35:21| Initializing https proxy context through google I found that "src all" is now inbuilt, but I could not restrict the users from surfing some sites through conditions. Can some body help me. Arun
