[Pdns-users] How to get pdns_recursor to listen on all interfaces?

[a b]

After some more testing:

local-address=0.0.0.0/32

throws an error.

local-address=0.0.0.0

works, reports that the pdns_recursor is listening on "0.0.0.0", and appears to make it listen on all interfaces.

However, this is undocumented in https://doc.powerdns.com/md/manpages/pdns_recursor.1/ as well as in the pdns_recursor's manual page.

Opened https://github.com/PowerDNS/pdns/issues/2873 to keep track of this.

I don't know if this has changed in the latest release, but the only way I could do it was to explicitly list the interface IP addresses in the local-address directive. =(

What is the syntax to specify that pdns_recursor listen on all interfaces (something like "0.0.0.0/32<http://0.0.0.0/32>")?

The issue I am facing is that, not knowing whether this is even possible, I am unable to automate this.
As far as I am aware, there is no way of reliably detecting the primary network interface on a multi-homed host, as per definition, a multi-homed host is a gateway for multiple networks and none of the networks has precedence over the other.

What I am trying to avoid is hard coding interface names or internet protocol addresses into the "local-address=..." configuration line in recursor.conf(4).
