Yes, but you'll have to redo the configuration if you update the name server (simple enough to do if you keep a backup, you've just got to remember to so). The caching package is a pre-configured system. You can manually configure the server in the same way, not using the caching pre-configuration package, to avoid that little snag. I have a collection of entries in my /etc/named.conf file like this: ------- begin paste ------- zone "doubleclick.net" { type master; file "dead.zone"; }; zone "doubleclick.com" { type master; file "dead.zone"; }; zone "ads.optusnet.com.au" { type master; file "dead.zone"; }; ------- end paste ------- And this is the /var/named/chroot/var/named/dead.zone file: ------- begin paste ------- $TTL 86400 @ IN SOA ns.localdomain. hostmaster.mail.localdomain. ( 200 ; serial 28800 ; refresh 7200 ; retry 604800 ; expire 86400 ; ttl ) IN NS ns.localdomain. ------- end paste ------- It ensures that there is no IP address returned for the query, at all, so they instantly fail (may require configuration of some browsers not to throw up annoying pop-up error warnings in the way). I found this better than directing all queries at a real IP address. It was slower, and meant that I had to have a local webserver running. -- (Currently running FC4, in case that's important to the thread) Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.
