====DNS Administration====

DNS is run by bind(aka namedb) and located on [[Servers Rainbow server]].

===Service Control===

**Reloading Bind**

A reload needs to be done after every new entry is made to the db files. This makes bind reload all the configuration and continue as normal.

1) Find the PID for the named process
%%ps -A | grep named
549 ?? Is 78:28.09 /usr/local/sbin/named -c/named.conf -t/etc/namedb -ubind%%

2) Send sig HUP to the process
%%kill -HUP 549%%

===Configuration===

General configuration is done in {{color c="blue" text="/etc/namedb/named.conf"}}. Domains and reverse DNS entries are made here. Host entries are made in {{color c="blue" text="/etc/namdb/master/<domain>.db"}.

**Adding a New Hostname**

Edit the following files to include A or CNAME records.

%%twix A 192.168.255.4
moose CNAME twix%%
