We have a DNS running.
Contents
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
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:
Bind as secondary
zone "hack" in{
type slave;
file "slave/slave.hack";
masters {172.31.0.5;};
};
Bind as Forwarder
zone "hack" in{
type forward;
forwarders {172.31.0.5; 172.31.116.1;}; };
};
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
edit
/etc/dnsmasq.conf
# Tells dnsmasq to forward anything with the domain of .hack to dns server 172.31.0.5 server=/.hack/172.31.0.5 # Listen to requests only coming from the local machine listen-address=127.0.0.1 # Do not cache anything # A decent dns server will already cache for your local network cache-size=0
and
/etc/resolv.conf
# local dnsmasq server nameserver 127.0.0.1 # Your main dns server (dnsmasq will forward all requests to this server) 208.67.222.222 OpenDNS / 172.31.0.5 main ChaosVPn DNS Server nameserver 208.67.222.222 nameserver 172.31.0.5
