Re: [Pdns-users] pdns-recursor works but pdns discards responses
We had a similar report from a Solaris SPARC user; a fix for his problem went into the 3.4.0 release, but we never got an answer about whether it helped. Can you please try with pens-server 3.4.0 or higher, and let us know if that fixes it?

Conntrack table size=3 snip Here is a final update with success. I removed recursor=127.0.0.1 from pdns.local.conf. I will also note that, my original problem was not so much a problem caused by a bug or some other such issue but more precisely, it was a configuration error. I theorize that the error I was seeing in my logs was not so much an error but an indication of the configuration error. In short, I had misconfigured the auth server to allow recursion. As such, when a non-authorized query came in, auth server passed it on to the recursor like it was configured to do and the recursor would respond correctly but the auth server then would drop the packets instead of routing them back to the source of the query. If anyone else has theories or additional input, please feel free to post a message to the list. As I mentioned, I’d mark this as solved and not as a bug in the pdns auth server code (big endian vs. little endian) but instead a user configuration error. Thank you everyone for your assistance on this problem. -- ___ Pdns-users mailing list Pdns-users@mailman.powerdns.com http://mailman.powerdns.com/mailman/listinfo/pdns-users

What was happening was when pdns was launched, it would look in /usr/local/etc/ for it’s configuration files. Of course this was wrong. After some short deliberation and with a hint from Fusl in the IRC channel, I modified /etc/default/pdns to add --config-dir=/etc/powerdns in the DAEMON_ARGS=“” line. The two other options are : add this same modification to the init.d script that was generated from the compile or at the time of compile, add --sysconfdir=/etc/powerdns to the ./configure command. Now I have a running 3.4.2 pdns but I still have the problem of the precursor responses being discarded. Right ha has me running a testrunner. -- ___ Pdns-users mailing list Pdns-users@mailman.powerdns.com http://mailman.powerdns.com/mailman/listinfo/pdns-users
