Comments for Dnsmasq : For Simple DNS Configurations


Anonymous said...

I am using the DB12cR2 RAC OL7 tutorial and I came across the problem of nslookup, which did not resolve the addresses, so I saw in another tutorial that it would be necessary to add an entry above the "search localdomain" with the value of "nameserver 127.0.0.1 "and that's how I managed to resolve it through nslookup. Can you tell me if to follow the tutorial, is this the correct method?

Hi.

"nameserver 127.0.0.1" sounds wrong. There is no DNS server on the RAC nodes, so why would they need to check themselves? The DNS Server is on a different machine. Wither the host PC, or another VM.

Cheers

Hi Tim,

newbie here. Do I need to install Dnsmasq on new Virtual Box Linux Server or can I install dnsmasq on each server that I am installing my Oracle RAC configuration on?

ehh nvm just seen your post.

Hi.

Yep. Either on the host machine, or in a separate VM is best. If you look at my Vagrant builds you can see how I do it.

Cheers

Where did you find this nameserver 192.168.0.4 and how do I find them on my RAC servers? they keep timing out when I do a nslookup

Tim... said...

Hi.

This is the IP address of the nameserver I set up. In this case it was on my PC. It's the IP of wherever you put the DNS.

Cheers
