We have a DNS running.

configs

The main zonefile atm is edited with vim on cvpn-dns.

This server is available at 172.31.0.5 or 212.12.52.216.

You can either be secondary and transfer the zonefile or query this server.

If you are a secondary you need to add your server here so it can be included in the zonefile.

secondarys

  • ns.sliepen.hack (172.31.116.1)
  • ns1.syn2cat.hack (195.24.78.86 and 2a01:608:ccc::ccc)
  • ns1.crest.dn42 (172.22.228.6) with 1Mbit/s upstream, ns2.crest.dn42 (172.22.228.85) and ns3.crest.dn42 (172.22.228.84) with 100Mbit/s upstream
  • ns.yojimbo.hack (10.103.252.85)

HowTo

NSD + unbound

unbound and NSD were developed by NLnet Labs with focus on small footprints and reliability. While NSD is a complete name server software for authoritative zones only, they also provide unbound as caching and recursive resolver.

nsd

In /etc/nsd/nsd3.conf add at bottom:

 zone:
       name: "hack"
       zonefile: "hack.zone"
       allow-notify: 127.0.0.1 NOKEY
       allow-notify: 172.31.0.5 NOKEY
       request-xfr: 172.31.0.5 NOKEY



unbound

In /etc/unbound/unbound.conf add at bottom:

 forward-zone:
 	name: "hack"
 	forward-addr: 172.31.0.5
 	forward-addr: 172.31.116.1
 forward-zone:
 	name: "dn42"
 	forward-addr: 172.22.228.85
 	forward-addr: 172.22.222.6


bind9

Should-Do´s:

in /etc/bind/named.conf (or for Debian in /etc/bind/named.conf.local):

NOTE: bind9 in debian now attempts to use DNSSEC, which you need to disable in /etc/bind/named.conf.options. Change 'dnssec-validation auto;' to 'dnssec-validation no;' and the static-stub defs should work.

Bind 9.8+ using static-stub (preferred method, Debian Wheezy or newer)

zone "hack" {
  type static-stub;      
  server-addresses { 172.31.0.5; 172.31.2.51; };      
};
zone "dn42" {
  type static-stub;
  server-addresses { 172.22.228.2; 172.22.136.243; 172.22.131.88; 172.22.53.51; };
};
zone "31.172.in-addr.arpa" {
  type static-stub;      
  server-addresses { 172.31.0.5; 172.31.2.51; };      
};
zone "100.10.in-addr.arpa" {
  type static-stub;      
  server-addresses { 172.31.0.5; 172.31.2.51; };      
};
zone "101.10.in-addr.arpa" {
  type static-stub;      
  server-addresses { 172.31.0.5; 172.31.2.51; };      
};
zone "102.10.in-addr.arpa" {
  type static-stub;      
  server-addresses { 172.31.0.5; 172.31.2.51; };      
};
zone "103.10.in-addr.arpa" {
  type static-stub;      
  server-addresses { 172.31.0.5; 172.31.2.51; };      
};

Bind as secondary

 zone "hack" {
   type slave;
   file "slave/slave.hack";
   masters { 172.31.0.5; };
 };

Old Bind as Forwarder

 zone "hack" {
   type forward;
   forwarders { 172.31.0.5; };
 };

maradns

maradns as secondary

 getzone mycoolnode.hack 212.12.52.216 > /etc/maradns/db.domain.hack

Where mycoolnode.hack is the domain name, 212.12.52.216 is the primary name server and db.domain.hack is the filename of the zonefile.

dnsmasq

Add to /etc/dnsmasq.conf:

server=/hack/172.31.0.5
server=/31.172.in-addr.arpa/172.31.0.5
server=/100.10.in-addr.arpa/172.31.0.5
server=/101.10.in-addr.arpa/172.31.0.5
server=/102.10.in-addr.arpa/172.31.0.5
server=/103.10.in-addr.arpa/172.31.0.5
