How to check DNS cache status in Mac OS X
- by admin
As a follow-up to How to Flush DNS Cache in Mac OS X I have received a question:how do I know if it worked? In other words, is there a way to check if the DNS cache is cleared?
To see the DNS cache status you may run
sudo killall -INFO mDNSResponder
Thus the SIGINFO signal will dump a snapshot summary of the DNS internal state to
/var/log/system.log
Voilà :-)
