Wiki: DNS server

[olluz]

Is this guide still valid for v8.x ?

dnsmasq is utilizing port 53. Would it be better to configure dnsmasq instead of unbound ? What implications would arise by disabling dnsmasq and using unbound ?

The guide should still work with PMG 8

dnsmasq is not a resolver in itself - but usually used as a forwarder (you point it to a DNS-resolver that does the resolution) - so it does not help in lowering the number of queries coming from the DNS-resolver you point dnsmasq to.

I hope this helps!

thanks for the reply. So, disabling dnsmasq or changing its listening port (away from 53) doesn't have any impact on PMG ?

PMG itself does not ship dnsmasq - so you need to evaluate if you need it in your environment.

In any case a SMTP server like PMG needs working dns - so either you have something listening on port 53 on localhost or you need to adapt your /etc/resolv.conf to point to a working DNS server

I hope this explains it.
