I'm taking a course on server administration at school and I have managed to set up virtual hosting in apache and a dns server on a virtual machine. However, I have now set up an old pc to run CentOS and I'm trying the same on that box.
The problem I ran into now is that I can't resolve hostnames from the linux box. I have set up the nameserver in /etc/resolv.conf to the IP of the CentOS machine, but when I try for example
ping google.com I get ping: unknown host google.com
However, when I do ping 66.102.13.105 (which is the Google IP, figured that out by pinging on my mac) I get:
PING 66.102.13.105 (66.102.13.105) 56(84) bytes of data.
64 bytes from 66.102.13.105: icmp_seq=1 ttl=52 time=15.5 ms
Slightly confused why this is happening. Could it be because of my router sitting in between the linux machine and the cable modem? It's a D-Link somethingsomething.
Thanks in advance

You need to make sure you can reach the DNS server. Also, the DNS server should be configured properly and should be able to query other DNS servers and/or access public DNS servers. You need to provide us with more details about your setup.

Well, probably the server that you set in resolv.conf is not accessible or it does not provide you an answer for google.com
dig @IP-of-your-dns-server google.com
and
ping IP-of-your-dns-server
Unlikely your router have anything to do with it.

The DNS server is running on the box itself. This is only for testing purposes, because I want to then set my mac's dns server to the test box and be able to use the domainnames I set up there (to fake them). Makes sense? Ping <ip> works, but the dig command doesn't work.
