It's possible to do this without modifications today. I'm using a cron
job:<br>
<br>
<tt>#!/bin/sh<br>
wget --quiet --output-document=/etc/dnsmasq.d/adservers \<br>
<a class="moz-txt-link-rfc2396E" href="http://pgl.yoyo.org/adservers/serverlist.php?hostformat=dnsmasq&showintro=0&mimetype=plaintext&useip=127.0.0.1">"http://pgl.yoyo.org/adservers/serverlist.php?hostformat=dnsmasq&showintro=0&mimetype=plaintext&useip=127.0.0.1"</a><br>
/etc/init.d/dnsmasq restart</tt><br>
<br>
If you use a different source for the blacklist, a little sed or awk in
necessary to reformat the list, but it just so happens that the
adservers list is available natively in dnsmasq format.<br>
<br>
Not to say that adding some blacklist functionality to dnsmasq doesn't
have its plus points, of course. Though I think I'd rather the
implementation stays with a single cache and adds a flag to mark an
entry as 'evil', than another cache is added solely for that purpose.
I'd like to see RBLs supported too (is that what you meant by
'blacklist servers'?).<br>
<br>

<br>
p.s. BTW, are you aware of the web content filtering features OpenDNS
provides? guess it depends what kind of blacklisting you're seeking.<br>

<p class="MsoNormal">I would like to request the ability of dnsmasq
to lookup dns
names on blacklist servers. If the dns name is blacklisted then return
a
specified configurable address, like 127.0.0.1, or a not found error
instead
of the true address and add it to a blacklist cache. I see it working
something
like this.<o:p></o:p></p>
