How to log requester IP?

[sergiopvilar]

Hello,

I was taking a look through the dnsmasq documentation and I would like to log the rquester IP using the --log-queries=extra option as described:

-q, --log-queries
Log the results of DNS queries handled by dnsmasq. Enable a full cache dump on receipt of SIGUSR1. If the argument "extra" is supplied, ie --log-queries=extra then the log has extra information at the start of each line. This consists of a serial number which ties together the log lines associated with an individual query, and the IP address of the requestor.

But when I change my /etc/dnsmasq.conf to this:

addn-hosts=/etc/pihole/gravity.list
domain-needed
bogus-priv
no-resolv
server=8.8.8.8
server=8.8.4.4
interface=eth0
listen-address=127.0.0.1
cache-size=10000
log-queries=extra
log-facility=/var/log/pihole.log
local-ttl=300

And I try to restart using sudo service dnsmasq restart, I get this:

[FAIL] Restarting DNS forwarder and DHCP server: configuration syntax check failed!

Any thoughts that could help me here?

Thank you!

Hi Sergio,
I confirm the same error in both a raspberry (dnsmasq 2.62) and in an ubuntu server (dnsmasq 2.52)

I suspect the "extra" facility is only available in the latest dnsmasq version (version 2.75) because the man page in the RPi doesn't show this option.

Indeed @jofrep. I've installed the 2.75 release manually and now seems to be working.

Would be great if pi-hole could install the latest version of dnsmasq.

Curious, what sort of extra information is provided? Could you show a snippet of the log?

@jacobsalmela just now I've realized that the default log shows the requester IP, closing here.
