dnsmasq cache

Hi,

How to know the records present in the dnsmasq cache? Whether it is doing its job at all?

Cheers

You can run dnsmasq in a debug mode for more information, and also check the -q option: http://www.thekelleys.org.uk/dnsmasq...smasq-man.html

Thanks for the reply, Sir. I will check that link.

Hi,

I have checked that link. It is well documented. And -q option will log the entries that dnsmasq is answering.
But probably there is no way to check the complete cache of dnsmasq?

Best Regards

This is a rather old thread, but, ....

dnsmasq can be persuaded to output some stats, even if not running in debug mode.

Code:

sudo killall -s USR1 dnsmasq
tail /var/log/syslog -n 10 | grep cache

for example

Note:- I increased the default cache size from 150 to 1000.
