We have a DNS running.
Contents
how to get entries
Email chaosvpn-join@hamburg.ccc.de to get an entry under .hack or to get a reverse-lookup for your IP / range registered.
configs
The main zonefile atm is edited with vim on cvpn-dns.
This server is available at 172.31.0.5.
You can either be secondary and transfer the zonefile, or query this server.
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
