Setup DNS Server
Setting up dnsmasq in an AWS EC2 t2.nano machine was as simple as can be. I added some hosts to the hosts file, and like magic, I have a DNS server that directly answers queries for which it finds domains in the hosts file, and provides pass-through answers for any other queries. Couldn’t be simpler.
To temporarily change dns server settings on Mac OS X…
We need to choose and identify a network interface. To see the choices listed:
networksetup -listallnetworkservices
Output may look something like this:
An asterisk (*) denotes that a network service is disabled.
Ethernet
LTE Mobile Router
FireWire
Wi-Fi
Bluetooth PAN
vpn-connection-1
vpn-connection-2
In my case, I’m using the Wi-Fi interface right now. So, to temporarily change the dns servers for that interface (use the IP address for your dnsmasq server):
networksetup -setdnsservers Wi-Fi 111.222.111.222
To remove the temp dns server:
networksetup -setdnsservers Wi-Fi Empty
To view current dns server settings:
networksetup -getdnsservers Wi-Fi
Note that the “normal” or default list of dns servers is empty. As far as I can tell, the OS uses the DNS servers configured with the network connection in Network Preferences unless those DNS server entries are replaced via networksetup.
Also worthy of clarification, the Network Preferences settings are per connection – i.e. different wi-fi connections can have different DNS server settings. The networksetup dns servers are per interface, meaning that when they’re applied to the Wi-Fi interface, those dns servers will be used for any wireless networks used via that interface.
