In the test section it is recommended that the reader tries
 
dig http://archlinux.org | grep "Query time"
 
However, on both my systems running dnsmasq-2.50, querying anything prefixed with a "http://" causes dnsmasq to automatically forward the query and not to cache the reply:
 
% dig "http://archlinux.org" | grep "Query time"; !#
 
;; Query time: 493 msec
 
;; Query time: 485 msec
 
The daemon logs
 
dnsmasq: forwarded query to 208.67.220.220
 
dnsmasq: forwarded query to 208.67.220.220
 
This might lead the reader to think dnsmasq is not working, when it actually works fine with:
 
% dig "archlinux.org" | grep "Query time"; !#
 
;; Query time: 508 msec
 
;; Query time: 0 msec
 
The daemon logs
 
dnsmasq: query[A] archlinux.org from 127.0.0.1
 
dnsmasq: forwarded archlinux.org to 208.67.222.222
 
dnsmasq: forwarded archlinux.org to 208.67.220.220
 
dnsmasq: reply archlinux.org is 66.211.214.131
 
dnsmasq: query[A] archlinux.org from 127.0.0.1
 
dnsmasq: cached archlinux.org is 66.211.214.131
 
So, I'm removing the "http://" prefix. -- [[User:Tresende|Tresende]] 11:39, 12 November 2009 (EST)

need information for fixed IPs

when this is set in rc.conf I think that require :

{ echo "nameserver 127.0.0.1"; grep -v "^#" /etc/resolv.conf | head -2; } > /tmp/resolv.conf

then backup /etc/resolv.conf and last :

mv /tmp/resolv.conf /etc/resolv.conf

Easier way to work with NetworkManager

If you add a line like

     dns=dnsmasq

to /etc/NetworkManager/NetworkManager.conf then not only will NetworkManager do the right thing about resolv.conf, it will also start up dnsmasq for us, which seems way easier. I just did it in my machine and it works OK. It uses a temp conf file for dnsmasq at /var/run/nm-dns-dnsmasq.conf, and resolv.conf has only 127.0.0.1. This is not OK if dnsmasq is used for DHCP server, but is very good for caching. As it seems to me this will be the most common pattern for people using NetworkManager, i added this at the start of the NetworkManager section, instead of at the end.

Also, i feel that calling "DHCP config" the section about adding 127.0.0.1 to resolv.conf is very easy to confuse with configuring the DHCP functionality of dnsmasq itself. So i just changed the name to "resolv.conf".

Nice edits, Mrpsbrk. I hadn't known about this so this is *nice*. Cleanedup the page a bit so all is OK. Danke --Gen2ly (talk) 23:17, 30 August 2012 (UTC)
