Nyota, named after Nyota Uhura, is intended to serve as the source of truth for PVVs DNS configuration. It is based on nix, and this repository should contain both the generating code and actual data.

Normal PVV "hosts" (servers or similar) should be defined in ./hosts.nix, and configuration and additional records can be placed in each zone configuration file in ./zones, such as ./zones/pvv.ntnu.no.nix.

Building DNS zone files

Provided you have nix on your system, you should be able to run nix build .#, and the resulting config is placed in ./result/zones.

Examples;

A host configuration like

  drolsum = {
    ipv4 = pvvv4 217;
    ipv6 = pvvv6 217;
    aliases = [ "login2" ];
  };

  roundrobin = {
    ipv4 = [ (pvvv4 101) (pvvv4 202) ];
    ipv6 = [ (pvvv6 101) (pvvv6 202) ];
  };

... will generate zone files like

drolsum.pvv.ntnu.no. IN A 129.241.210.217
drolsum.pvv.ntnu.no. IN AAAA 2001:700:300:1900::217
login2.pvv.ntnu.no. IN CNAME drolsum

roundrobin.pvv.ntnu.no. IN A 129.241.210.201
roundrobin.pvv.ntnu.no. IN A 129.241.210.202
