<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>
<p>Cheers,<br>

<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>
