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?
You can point it to itself if you wish; this is what I do.
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...)?
More detail? Not sure of the question; perhaps an example?
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.
You *should* block it via iptables. However, you should *also* read the man page for named.conf. Pay particular attention to the "listen-on" directive. I suggest you also read the "forward-first" and "forwarders" directives. Those ought to take care of most of your needs right now.
Post further questions if necessary. BTW, any feedback or suggestions for the "DNS First Steps"? Anything that could be added that would have immediately made your life or your understanding easier?
