Logging All DNS Queries

I would like to configure PowerDNS to log all DNS queries to a text
file or to a MySQL table. Does anyone know if this is possible? _______________________________________________ Pdns-users mailing list Pdns-users@... http://mailman.powerdns.com/mailman/listinfo/pdns-users |

Bryan, The PowerDNS Authoritative Server does not have this ability, the PowerDSN Recursor does ('quiet=off'). Another solution that is far less resource intensive is to run a tcpdump on your UDP port, and use tools like 'ncap' to make reports on what queries you've seen. Good luck! _______________________________________________ Pdns-users mailing list Pdns-users@... http://mailman.powerdns.com/mailman/listinfo/pdns-users |

There is the query-logging setting, but given Bert's response I wonder if it is implemented in any backend. I thought I'd used it once but it's been a while so maybe I recall incorrectly. I find that the stats given on the web-server tool answer every question I want to know about who is querying and for what. For performance monitoring I have tests that make queries using '/etc/init.d/pdns mrtg'.

Most DNS queries lead to ANY-backend queries, so you won't be able to see the type of the DNS query. > I find that the stats given on the web-server tool answer every > question I want to know about who is querying and for what.

You could just tcpdump / tethereal your port 53 traffic I suppose,
they're generally oneliners that you can easily stick in a logfile to process. bert hubert wrote: > On Wed, Jul 22, 2009 at 7:49 PM, Bryan > Brannigan<bryan@...> wrote: > >> I would like to configure PowerDNS to log all DNS queries to a text >> file or to a MySQL table.
