I don't think playing with a cut down, or limited feature DNS server is worth the bother. Though the basic one that Fedora has will let it read the /etc/hosts file on that particular machine, for it to resolve queries for. It all depends on whether you want to learn how to use DNS, or just figure out one particular server software. You'd approach it in a similar way to my prior message, about either using some commonly used LAN domain names, or registering a real one (which has benefits that you'll appreciate in the future). Set up DNS records using that name, set up your DNS server to resolve those queries, and to resolve your clients queries about the rest of the web. Set up your clients to use that DNS server. The "domain" or "search" parameter in /etc/resolv.conf will append the domain name to any hostname that you use. e.g. "ping two" would expand into being treated as if you'd typed "ping two.localdomain". If you're setting DNS records for your clients, then you need to make sure that they always use the same IP, either by manually setting them that way, or using DHCP to always give them the same IP. The alternative is have a DNS and DHCP server that talk to each other, and each time the DHCP server gives a machine an IP, it puts the information about it into the DNS server. Well, actually they're not mutually exclusive ways of doing it. My LAN uses machines in all those ways. The main server has an IP fixed by its own configuration. The usual clients have IPs fixed by the DHCP server. And guests get the full automatic treatment by the DHCP server. With the DHCP server informing all clients of the local DNS server address. Other than the occasional bit of problem solving, I haven't had to refer to a machine by its numerical IP in many years, I've always used hostnames. -- [tim@localhost ~]$ uname -rsvp Linux 3.9.10-100.fc17.x86_64 #1 SMP Sun Jul 14 01:31:27 UTC 2013 x86_64 Boilerplate: All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I only get to see the messages posted to the mailing list.
