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!)
