dnsmasq reading /etc/hosts, but not using it
I've done a default install of dnsmasq. When I run dig, it seems to be using dnsmasq (127.0.0.1), but the results don't include the hostnames included in /etc/hosts.
/etc/hosts:
192.168.1.13 sun
in a terminal:
$ dig sun
; <<>> DiG 9.6-ESV-R4 <<>> sun
;; global options: +cmd
;; Got answer:

I've tried using local and expand-hosts/domain, but can't seem to get either of those working either. My primary goal is to be able to use one machine to host LAN DNS, I don't care if the names wind up being sun or sun.domain, whatever works.
Here is my /etc/resolv.conf
nameserver 127.0.0.1
domain members.linode.com
search members.linode.com
nameserver 72.14.188.5
nameserver 72.14.179.5
and /etc/dnsmasq.conf
domain-needed
bogus-priv
This is all on an ubuntu 10.04 machine if it makes a difference. I have been following this guide: http://www.mythicalbeast.co.uk/linux/dnsmasq_howto.html (though not verbatim since that also sets up DHCP)
I know this is from 2011, but since it still has no accepted answer:
Today, I had a similar problem. Curl worked to get the expected response from a haproxy lxc with the respective header, but somehow my local dnsmasq did not provide resolution for container.test
(confirmed with nslookup).
Google found me this post by Hugo Heden, who said that is might be an issue with /etc/hosts
formatting.
What solved the problem for me was:
- Uncommenting
no-hosts
in/etc/dnsmasq.conf
- Putting
123.123.123.12 container.test
into a new file, e.g./etc/dnsmasq.hosts
- Pointed dnsmasq to the new file by adding
addn-hosts=/etc/dnsmasq.hosts
to/etc/dnsmasq.conf
This snippet from the dnsmaq FAQ seems relevant:
Q: Names on the internet are working fine, but looking up local names from /etc/hosts or DHCP doesn't seem to work.
A: Resolver code sometime does strange things when given names without any dots in. Win2k and WinXP may not use the DNS at all and just try and look up the name using WINS. On unix look at "options ndots:" in "man resolv.conf" for details on this topic. Testing lookups using "nslookup" or "dig" will work, but then attempting to run "ping" will get a lookup failure, appending a dot to the end of the hostname will fix things. (ie "ping myhost" fails, but "ping myhost." works. The solution is to make sure that all your hosts have a domain set ("domain" in resolv.conf, or set a domain in your DHCP server, see below fr Windows XP and Mac OS X). Any domain will do, but "localnet" is traditional. Now when you resolve "myhost" the resolver will attempt to look up "myhost.localnet" so you need to have dnsmasq reply to that name. The way to do that is to include the domain in each name on /etc/hosts and/or to use the --expand-hosts and --domain options.
So I suggest you post your /etc/resolv.conf
, as well as the arguments you are feeding to dnsmasq when you start it.
Something I found: Everything appears to be configured ok, but dns name from /etc/hosts is not resolving. After adding/editing /etc/hosts (or any config file), don't forget to restart dnsmasq process to re-read the file. Dnsmasq imports these files on startup, it's not a live lookup.
What does your /etc/resolv.conf look like? Look for domain or search elements.
Setup a .local domain for dnsmasq and then add that to your resolv.conf and it should work.
Try dig sun.local @localhost.
