Unmanaged VPS + DNS BIND = DNS ne radi

Postano: 14 vel 2013, 22:13
Postao/la phreakbox
Pozdrav,

kratko: domain name treba resolvat 1 IP adresu na unmanaged VPS serveru

server: Debian 6, hoster: r.a.m.n.o.d.e (stavio sam tocku da ne moras bas svatko znat o serveru) 5GiB, VPS SSD 1 gbps

instalirano: ntp, apache, mysql, php5, vhosts, a2enmod, upgrade-an, .... sve što je bitno osim BIND-a s kojim nisam baš szbunjen, ssh, user,...

situacija:

DOMENA:
domain.com > trebam assign-at NS adrese (1 adresa za 1 VPS, 2 ima smisla za shared)

VPS server, testiran, cca vuce 40 MB/s iz UK od Mannheim-a (wget ISO slike ubuntu-a test), ok, brz je, štima, samo 128 MB RAM-a al za sad ne trebam više jer će gore bit samo wordpress

OpenVZ, dobio sam javnu IP adresu, nema postavke za ns (probao sam njihov NS postaviti u DOMAIN.COM adresi ns1000.r.a.m.n.o.d.e.com) > nslookup ne pointa na VPS server.

Trenutno stanje:

marin@skymond:~$ nslookup mojadomena.net
Server:		127.0.1.1
Address:	127.0.1.1#53

Problem je što ne mogu dobiti nslookup-om ns1.mojadomena.net da mogu assignat ns adrese iz domain.com
Na managed serverima tj. na m.i.n.i.v.p.s.c.o.m to je odmah proradilo nisam se morao igrati sa NS-om i BIND-om.

A gdje ti je forward zona, postao si samo konfiguraciju reverse zone ?

NS rekordi bi trebali navoditi puno ime ( host.domena.tld.).

Postaj i sve konfiguracijske datoteke servisa !

Joj, bind mi je popio solidnu količinu živaca. Iskreno, trebal isu to (kao i mnogo toga drugoga, puno jednostavnije uraditi). E sad, vidim da ti niti rndc nije dobro konfiguriran. To isto trebaš srediti, i db fajl ne bi trebao biti u /etc/init.d već u
/etc/bind/zones folderu

Daj samo prikljuci konfiguracijske datoteke uza svoj odgovor. Bilo bi dobro kada bi prikljucio i svoje zonske datoteke.

Unutar datoteke "/etc/bind/named.conf.default-zones" dodaj:

Kod: Označi sve

listen-on { any; };
Takodjer dodaj forwardere (zamijeni xxx s IP adresom hosting providera):

Kod: Označi sve

forwarders { xxx.xxx.xxx.xxx; };
Unutar datoteke "/etc/bind/named.conf.default-zones" dodaj blokove unutar kojih ces naznaciti svoje zonske datoteke (prvi blok je za forward zonu, sample sam prikljucio na kraju; drugi blok je za reverse zonu (to vec imas)):

Kod: Označi sve

zone "mojadomena.tld" in {
