<p>Any command line parameters are accepted as options in config
file without leading --. max-ttl=x can be used just like
local-ttl=x. dnsmasq.conf does not include all supported options,
just add it anywhere you want. To the beginning or to the end or
to /etc/dnsmasq.d/ttl.conf, does not matter.</p>
<p>It is supported when it is in the manual page. Just omit -- in
conf file.</p>
<p>Cheers,<br>

DNSMASQ

<p>Hello Omair,</p>
<p>dnsmasq 2.48 in RHEL6 is quite old and does not contain
support for max-ttl. That was added in dnsmasq 2.53 and
would be present in RHEL7 if you can consider upgrade. Even
that version is receiving only important updates and is also
rock-stable. I am afraid no supported parameter has the same
effect. Only local-ttl and neg-ttl are supported for
adjusting TTL in 2.48.<br>
</p>
<p>Other option would be building your own build of dnsmasq,
where you could build something more recent. RHEL6 would not
receive any updates except critical bugs and security
issues, it won't change in the distribution.<br>
</p>
<p>Best Regards,<br>
Petr<br>

<p>Please report what is on line 56.</p>
<p>Following command would print just that:<br>
</p>
<p>sed -e '56!d' /etc/dnsmasq.conf</p>
<p>I doubt that is about max-ttl option. Are you still
using RHEL6 (or derivate) for some reason? I thought
every option is supported in more recent versions. I
would like to know what option were supported in the
old but is not in current version. Please Share.</p>

<br>
what exactly does "didn't work" mean?<br>
does dnsmasq still refuse to start?<br>
do you have any error message?<br>
did you try to stop it before starting?<br>
