This is what I have done:
I have made a file, resolv.servers with the nameservers I want to use. I have
edited resolv.conf so that it looks at 127.0.0.1. I have put PEERDNS=no into
ifcfg-eth0 so that resolv.conf does not get overwritten at boot. I have
edited dnsmasq.conf to use only resolv.servers in strict order.
I am able to connect to the internet and I can verify that I am using my
chosen nameservers, so this setup appears to be working.
I have set up 2 computers and have exactly the same files in both.
On one computer, when I type dig someplace.com the search takes ~300ms and
subsequently ~0ms and no lights flash on my adsl router. Caching appears to
work.
On the other computer, when I type dig someplace.com the search takes ~300ms
and subsequently ~35ms and lights flash on my adsl router. I suspect caching
is not working.
What is happening here? How does one properly set up dnsmasq to do dns
caching? Why is the same setup acting differently on the 2 machines? Network
Manager is not enabled on either machine.
Any ideas?
Seems to me caching _is_ working, though why the difference I cannot say.
Use tcpdump* to listen to the relevant interface, port 53 on each and
see what's the difference.
* Or wireshark. Wireshark has a nice GUI.
