DNS

DNS

The project runs authoritative DNS servers for any constituent projects that wish to use them. The servers run Bind on a hidden master which handles automatic DNSSEC zone signing while the public authoritative servers run NSD.

Adding a Zone

To add a new zone, identify an existing git repository or create a new one to hold the contents of the zone, then update :git_file:`inventory/service/group_vars/dns.yaml`.

Run:

dnssec-keygen -a RSASHA256 -b 2048 -3 example.net
dnssec-keygen -a RSASHA256 -b 2048 -3 -fk example.net

And add the resulting files to the dnssec_keys key in the group/adns.yaml private hostvars file on puppetmaster.

If you need to generate DS records for the registrar, identify which of the just-created key files is the key-signing key by examining the contents of the files and reading the comments therein, then run:

dnssec-dsfromkey -2 $KEYFILE
