=== Testing without "http://" ===
+
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

Force DNS cache persistence?

I've noticed that the DNS cache expires very quickly (less than 60 seconds) for many domains thereby defeating the purpose of caching it in the first place. Is there a way to force entries to last longer? Neounk (talk) 01:30, 31 March 2013 (UTC)
