I have complie dnsmasq version 2.55 on Centos 5.3 and facing problem in max-ttl
option.
I set max-ttl=691200 and try to check it, I think its not working. I want if
any request goes through my dns its store for 8 days.
Here is my configuration which I set in my dnsmasq.conf file.
bogus-priv
filterwin2k
cache-size=59000
no-negcache
dns-forward-max=25000
max-ttl=691200
And here is my testing result.
