Re: [PATCH] RPZ: bug fix and code update

Michael,

Sorry for putting you on the spot, but what do you want to do with this RPZ add-on?

I saw your comments in the Dev Mailing List of "generally being in favor of trying this path" (bad paraphrasing on my part)

I saw your comments in bugzilla at https://bugzilla.ipfire.org/show_bug.cgi?id=13254#c171

I am not interested in anything regarding the RPZs right now. They have not been properly put on the agenda and looking at how much time we have on our hands, this won't make it on the agenda for years.

I don't want to build blockers, but this ticket is about a different problem which I want to solve first.

How do you want to go forward?

Jon

More questions!

Currently RPZ config files are at `/etc/unbound/local.d` but this directory seems like it is for user (admin) customizations.

[root@ipfire ~] # ls -al /etc/unbound/local.d
total 68
drwxr-xr-x 2 nobody nobody 4096 Aug 12 13:41 .
drwxr-xr-x 4 root   root   4096 Aug 12 00:52 ..

[root@ipfire ~] # 

Each file is a config file per category (or one per RPZ file). This makes it easy to add or remove a category (or RPZ file).

Should I create a new unbound directory for RPZ config files? Maybe `/etc/unbound/rpz.d`? Or `/etc/unbound/rpz`?

changed all paths from `/var/ipfire/rpz/` to `/var/ipfire/dns/rpz/` (thank you to Adolf!)

rpz-config:

• bug: corrected "Type" test from block to allow
• removed verbose parameter from various commands

rpz-metrics:

• bug: corrected grep for rpz name count
• bug: fixed divide by zero error (thank you Peppe!)

install/uninstall:

• bug: corrected scripts (thank you Bernhard!)
