Our InternetServer, liberty, provides DNS (Domain Name System) service. We use ISC BIND.

liberty is the SOA nameserver 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.

liberty is configured as a BIND master server for the gnhlug.org domain. Some other name servers are slaved to liberty for the domain. As of this writing, the only active slave is rogue.codemeta.com. It is delegated from the 2LD and listed in the zone file.

We are in the process of bringing up some DynDNS slaves as well. These will be ns2.mydyndns.org, ns3.mydyndns.org, ns4.mydyndns.org, and ns5.mydyndns.org. They are listed in the zone file, but have yet to be delegated from the 2LD.

BIND 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.

BIND runs chrooted under /var/named/.

linux.codemeta.com used to be an authorative nameserver for the gnhlug.org domain. It does not currently have anything to do with DNS for gnhlug.org. (But thanks for hosting it for so long, Bruce!)
