Hi, Using pipe backend with unix socket to connect to another process which is responsible for sending response of DNS queries. In case of NXDOMAIN there are multiple communication between PDNS and the backend process. Below are the logs:
Jun 18 11:09:26 Query: 'Q abc.com.my.domain.com IN SOA -1 127.0.0.1' Jun 18 11:09:26 Query: 'Q com.my.domain.com IN SOA -1 127.0.0.1' Jun 18 11:09:26 Query: 'Q abc.com.my.domain.com IN NS -1 127.0.0.1' Jun 18 11:09:26 Query: 'Q abc.com.my.domain.com IN ANY -1 127.0.0.1' Jun 18 11:09:26 Query: 'Q *.com.my.domain.com IN ANY -1 127.0.0.1' However for cases when response is found then the communications are less. here are the logs: Jun 18 11:10:40 Query: 'Q xyz.com.my.domain.com IN SOA -1 127.0.0.1' Jun 18 11:10:40 Query: 'Q xyz.com.my.domain.com IN ANY -1 127.0.0.1' Is there anyway we can reduce the NXDOMAIN communication calls and make it more faster? -- IB -- View this message in context: http://powerdns.13854.n7.nabble.com/How-to-send-NXDOMAIN-using-pipe-backend-tp11628.html Sent from the PowerDNS mailing list archive at Nabble.com. _______________________________________________ Pdns-users mailing list [email protected] http://mailman.powerdns.com/mailman/listinfo/pdns-users
