Hi All, I am using pdns-server 3.3.1 with pdns-recursor and pdns-backend-mysql After installing the almost everything is working perfectly, accept for the reverse DNS.
To test powerDNS and powerDNS recursor I created a test network. It is a star VPN network with: - 1 main router - 2 subrouters . Behind each router I have clients, making use of the DNS which is behind the main router. Now here is what goes wrong with the reverse lookups: When I am behind the main router (10.20.0.0 network): dig -x 10.20.0.2 ==> answer dig -x 10.20.1.2 ==> answer dig -x 10.20.2.2 ==> answer When I am behind the first router (10.20.1.0): dig -x 10.20.0.2 ==> answer dig -x 10.20.1.2 ==> no answer dig -x 10.20.2.2 ==> answer When I am behind the second router (10.20.2.0): dig -x 10.20.0.2 ==> answer dig -x 10.20.1.2 ==> answer dig -x 10.20.2.2 ==> no answer So it seems that it will not send an answer to me when I am asking for a reverse lookup, when I am in that network itself, unless I am in the main network. I tried everything from upgrading from pdns 3.1 to 3.3.1 to installing everything again etc. I just can't get it to work. Maybe you can help? Here are my config files: pdns.conf ----------- allow-recursion=127.0.0.1 cache-ttl=60 config-dir=/etc/powerdns daemon=yes disable-axfr=yes guardian=yes lazy-recursion=yes local-address=0.0.0.0 local-port=5300 log-dns-details=yes log-failed-updates=yes logfile=/var/log/pdns.log logging-facility=0 loglevel=4 module-dir=/usr/lib/powerdns query-cache-ttl=60 recursor=127.0.0.1:53 setgid=pdns setuid=pdns socket-dir=/var/run wildcard-url=yes gmysql-host=localhost gmysql-port=3306 gmysql-dbname=pdns gmysql-password=Password gmysql-user=pdns gmysql-socket=/var/run/mysqld/mysqld.sock recursor.conf ------------- allow-from=127.0.0.0/8, 10.0.0.0/8, 192.168.0.0/16, 172.16.0.0/12, ::1/128, fe80::/10 local-address=127.0.0.1, 10.20.0.4 local-port=53 log-common-errors=yes max-negative-ttl=3600 quiet=yes setuid=pdns version-string=PowerDNS Recursor 3.3 When starting the recursor I do see these messages: --------------------------------------------------- PowerDNS Recursor 3.6.1 (jenk...@autotest.powerdns.com) (C) 2001-2014 PowerDNS.COM BV Using 32-bits mode.
