Hi, on my server i have 2 network interfaces. With the default option: local-address=0.0.0.0 Server doesn't respond. And in the documentation, it's written that this value so configured make PDNS listening on all interfaces. If i set it with my 2 IP (so all interfaces) it works. Any idea? Thankyou _______________________________________________ Pdns-users mailing list Pdns-users@... http://mailman.powerdns.com/mailman/listinfo/pdns-users |

Hi Leen, "It is highly advised to bind to specific interfaces and not use the default 'bind to any'. This causes big problems if you have multiple IP addresses. Unix does not provide a way of figuring out what IP address a packet was sent to when binding to any."" Ok, so it seems an unix-related problem.

Local IP address to which we bind. You can specify multiple addresses separated by commas or whitespace. It is highly advised to bind to specific interfaces and not use the default 'bind to any'. This causes big problems if you have multiple IP addresses. Unix does not provide a way of figuring out what IP address a packet was sent to when binding to any." http://docs.powerdns.com/all-settings.html So my guess is the default IP-address (default gateway) works, but the otherone doesn't if you use 0.0.0.0. If you are using the recursor, I guess the same thing applies and maybe the documentation should be enhanched. Hope that answers your question > > > ------------------------------------------------------------------------ > > _______________________________________________ > Pdns-users mailing list > Pdns-users@... > http://mailman.powerdns.com/mailman/listinfo/pdns-users _______________________________________________ Pdns-users mailing list Pdns-users@... http://mailman.powerdns.com/mailman/listinfo/pdns-users _______________________________________________ Pdns-users mailing list Pdns-users@... http://mailman.powerdns.com/mailman/listinfo/pdns-users |

That isn't right, you have to bind a listener to each interface and then use that specific instance to reply to incoming queries. -- Best regards, Duane http://www.freeauth.org - Enterprise Two Factor Authentication http://www.nodedb.com - Think globally, network locally http://www.sydneywireless.com - Telecommunications Freedom http://e164.org - Global Communication for the 21st Century "In the long run the pessimist may be proved right, but the optimist has a better time on the trip." _______________________________________________ Pdns-users mailing list Pdns-users@... http://mailman.powerdns.com/mailman/listinfo/pdns-users |
