The BIND DNS server uses its own configuration files to give answers to queries. In general, it looks for its own DNS record files, then queries external (to itself) DNS servers. The hosts file isn't part of its workings. There are other (simple) DNS servers which can look at the hosts file for resolving addresses. Amongst other things, the /etc/nsswitch.conf file lists how various things will resolve queries. Such as your web browser's query for a domain may get resolved by first looking in the hosts file, then trying a DNS server. The "hosts:" line will configure how names are generally resolved, there are other configuration lines to choose how other things do their look-ups. Squid has its own resolver tool, and I can't recall how it normally works, but I'd be surprised if you can't configure how it goes about it. It shouldn't be necessary to play around with restarting networks, or rebooting, for a change in your hosts file to be noticed. However, certain applications may need restarting. For instance, if you'd used Firefox to browse www.example.com, the IP would have been looked up at the time, and the answer will be held onto for the session. So, changes to the IP won't get noticed, during that time. -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored.
