Howto log DNS ?

[Amelie]

Hi,

i can't find any DNS log entries in the system log

Heard about dirty tricks of keyloggers, transmitting
collected data within DNS requests.

How to monitor such DNS requests ?

DNS requests are not logged by design. Perhaps you've to check dnsmasq site to check on how to activate debug mode.

Hi Amelie,

you can restart dnsmasq with the --log-query (-q) option and all DNS request will appear in the log file as soon you send an SIGUSR1 to dnsmasq.

see the dnsmasq man page (http://downloads.openwrt.org/people/nico/man/man8/dnsmasq.8.html)

Bye,

Matthias
