Thanks! I was able to get things set up and working so far as I can tell. I spent some time with the HOW TO along w/ your docs. I set up 2 zones. The local zone and the zone for my internal network. After adding the proper hosts and NS entries, everything else fell into place. A few questions remain though... If I am running a nameserver locally, does resolv.conf become irrelevant on the machine running named? Since this machine is also my gateway to the Internet, do I still need to specify entries in /etc/resolv.conf for external names or can I point it to itself? (I know I must do this on the client end, but what about the server end)? Still fuzzy on this one... Also, how do things work if the host entry in the zone file has a dynamic IP (not likely, just curious how this works out...)? Some security questions immediately come to mind as I type :) I am wondering how I can block external traffic using my machine as a resolver. I suppose I can control this through iptables, but I was wondering if named provided anything special for this. No big deal... I'll research this one later...
