Our InternetServer, =liberty=, provides DNS (Domain Name System) service. We use ISC BIND =named=. It runs runs chrooted under =/var/named/=. =liberty= is the SOA nameserver and BIND master for the =gnhlug.org= domain. At the TLD (Top Level Domain) servers, there are NS records which delegate authority for =gnhlug.org= to liberty and its peers. This is how other DNS resolvers in the world find out which nameservers to ask about the domain. Some other name servers are slaved to =liberty= for the =gnhlug.org= domain. As of this writing, all the slaves are [[http://www.dyndns.com][DynDNS]] nameservers. These are =ns2.mydyndns.org=, =ns3.mydyndns.org=, =ns4.mydyndns.org=, and =ns5.mydyndns.org=. They are delegated from the 2LD, listed in the zone file, and listed in the =named.conf= file on =liberty=. !DynDNS secondary nameserver service is donated by [[Main.ColeTuininga][Cole Tuininga]]. Thanks, Cole! =named= also provides a full-service, caching resolver for the software running on liberty. Only liberty itself is permitted to make use of this resolver. Other IP addresses are denied. This is accomplished via =allow-querry= statements in the =named.conf= file. =linux.codemeta.com= and =rogue.codemeta.com= used to be authorative nameservers for the =gnhlug.org= domain. They no longer have anything to do with DNS for =gnhlug.org= -- but thanks for hosting it for so long, [[Main.BruceDawson][Bruce]]!
