Hi All, First of all thanks for the help provided. As Peter in one of my earlier queries gave me a pointer and following that it is quite trivial to create our own Backend in PowerDNS and using getRemote(), I was able to retrieve the Client's resolver IP.
PowerDNS is indeed quite simple to extend. Thanks for this architecture. I have one problem though. My backend is getting called multiple times. Even though I just send a single query using the host command. Just to show I put some output statements and these are printed after I sent the client query Here's the console output: *************************************************************************************** Nov 16 11:20:26 Creating backend connection for TCP Constructor called % Nov 16 11:20:26 [bindbackend] Parsing 1 domain(s), will report when done Nov 16 11:20:26 [bindbackend] parsing 'example.com' from file '/etc/bind/example.com.zone' Nov 16 11:20:26 [bindbackend] Done parsing domains, 0 rejected, 1 new, 0 removed Constructor called Nov 16 11:20:26 About to create 3 backend threads for UDP Constructor called Constructor called Constructor called Constructor called Constructor called Constructor called Nov 16 11:20:26 Done launching threads, ready to distribute questions Nov 16 11:20:35 Distributor misses a thread (4<5), spawning new one looked up looked up looked up looked up Constructor called Constructor called *************************************************************************************** How I can reduce this to a single lookup() call from the PowerDNS to my Backend?. Even constructor is called many times. Can this be configured anywhere? Thanks, Nikhil.
