[Pdns-users] get running config from recursor?

[Charles Sprickman]

Hi all,

This is a simple one, fits entirely in the subject line. :)

I know I can get the startup config from the API or "rec_control get-parameter [the paramater I want to check]", but how do I get the current running config.

I imagine most of your users at this point are folks running giant sites and all, but we started using the recursor way, way back when we found djb's dnscache couldn't keep up with what we were doing - like really early days IIRC, and we just stuck with it, so please bear with me a bit - I'm not at all a power user here, I haven't even touched things like dnsdist (or had a need to)

Basic scenario - I have the recursor running and want to make a change to the running config, for example:

"rec_control set-minimum-ttl 1000"

And in the config file that value is either not set or is set to a different value

Now I come back in a few weeks and ask myself "what did I set that to? I should probably put it in the config file!", so:

"rec_control get-parameter minimum-ttl-override"

And that provides me with the configured, but no running config.

Same for something like:

curl -s -H 'X-API-Key: secret' http://10.99.88.131:8082/api/v1/servers/localhost/config|grep minimum

I kind of hijacked a github issue, but I think we were talking past each other here:

https://github.com/PowerDNS/pdns/issues/2580

It should be possible to see the running config somewhere, right? Even people running in a fully containerized, automated environment start with some initial tinkering in a test environment somewhere where they're manually making changes by hand and testing, right? And you need to know where your config is at after a bunch of fiddling about with various params...

Thanks,

Charles
