I've never come across RPZ before, haven't heard of it.
But I'm not sure what do you mean here. How is it possible
to use RPZ for this task, to override a name with an (expanded)
For example, in example.com domain I want to add an "fs" CNAME
record pointing to foo.example.com. How would I do that with
That should be a qname trigger, but I'm lost for now about the action.
name: "example.com" # arbitrary?
with example.com.rpz containing:
fs.example.com. CNAME rpz-drop.
And if I want to configure another such name, I'll have to
create another rpz zonefile and another rpz section?
Lemme try... hmm, immediately this file (rpz) has been overwritten,
with contents of example.com zone. It looks like I don't see how
this works, and why it removed the data I've put there.
Or does this need another indirection, to configure this "rpz zone"
on some other primary? And to serve different contents to different
sites, I'll have to configure SEVERAL primaries?
Or am I out of track completely?
I'll try to configure this one test zone in nsd. But this whole
thing quickly becomes unmanageable...
