Michael,
Sorry for putting you on the spot, but what do you want to do with this RPZ add-on?
I am not sure this is a question for only me.
I personally just don’t have any capacity to take on another rather large project as I have a huge backlog of so many things and I feel like a lonely fighter getting these all over the line. For my own sanity I need to have a couple of those closed before thinking about the next ones.
A couple of months ago we have talked on the monthly call about RPZ and the decision that was made by the people was to not look at this now, just because there were other more pressing things. We could also not find answers to the questions that led us into RPZ:
- Are there any good lists out there that would allow us to replace the URL Filter? That thing is basically on its last leg because of the lack of lists. We need to be able to block ads and pr0n and that very reliably.
I believe this exists with the Hagezi lists at https://github.com/hagezi/dns-blocklists and/or the addition of a chosen "oisd NSFW" list at https://oisd.nl/setup
I understand there is no time to review to see if this meet the needs. So we can leave this as "I believe these exist" for now.
So, I am not sure what to think of all these things on GitHub. It seems that there are many repositories that pop up and presumably disappear in the same kind of way. We see this with the IP blocklists.
We want quality blocklists. I know that we don’t have too much on the URL Filter front, but I would prefer to avoid putting so much work in if we in the end stand where we started.
This makes perfect sense. Based on the comments I’ve seen it seems like Hagezi is growing in popularity and in offerings.
Gerd (the owner) is very responsive, involved and I keep running into his posts when searching for RPZ "things". Gerd quickly made changes per my request: see https://github.com/hagezi/dns-blocklists/issues/2301. Now there are two TLD RPZ lists.
Like everything else I cannot predict how long it might last.
- We need to look into privacy when RPZs are being realised over DNS - I don’t even understand why we are suddenly starting to pull text files over HTTP again. The IPS seems to have most of these lists already.
All of the lists that I am pull are HTTPS. And HTTPS only is currently checked (validated) in the existing `rpz-config` code.
What a lost case. DNS is a globally distributed, cacheable protocol. We could simply put all those blacklists into the DNS caches all around the world. They would respond fast, be local to so many people, but instead we download massive text files. That means that whenever something changes the entire file needs to be transferred again. They are huge. We would want many fast updates which are not possible that way… but I digress.
I came across one DNS service that offers the Hagezi lists as part of their available DNS services. If interested I can find and post the details.
How much traffic did you observe?
I have 11 RPZ list (honestly too many but I am experimenting) and that eat up about 230M bytes per day.
How is Unbound refreshing these?
Unbound RPZ takes care of the updates automagically. There is no cron entry.
Each RPZ list includes an SOA line similar to this: `@ SOA localhost. root.localhost. 1723093380 43200 3600 259200 300`
The 43200 is the refresh period in seconds. So this RPZ list auto updates every 12 hours.
Is there a local cache?
Yes, it is part of unbound. (Nothing we need to setup)
Regarding your code, there are some issues with the coding style, but I heavily appreciate the pioneering to bring this feature to life.
My style is camelCase, but if you prefer snake_case that is an easy change (please speak up).
As for as other style changes, that can wait until time is available by the core developers.
It is mainly that you make things very complicated for yourself. Call “cat”, not “/bin/cat”. There is no guarantee that things will stay where they are now and the shell has lots of builtins that execute a lot faster.
I will remove the executable paths. What builtin did you see that I missed? Anything else?
And this is all designed to work on the shell. We need something for the web UI.
For commands within the WegGUI there are `safe_system` commands on the `.cgi` page.
But I am guess you are referring to something else.
What it would need to be finally merged would be a web UI though. So I think we have a long way ahead of us.
The attachment is an early mock-up I made a few months ago (made with Pixelmator Pro). The WebGUI is being worked on now.
<mock-up.png>
I think we might look for something that is very similar to the IPS ruleset editor or the IP blocklists.
I am not even sure if we would require users to manage this or whether we would curate a list like with the IPS and IP blocklists.
The first "DRAFT" of this was for the user/admin to manage the list. For the RPZ add-on, I’d prefer to keep it this way until we figure out if RPZ is popular and used by the user/admins.
And yes, it could be changed to a set list like IPS. FYI - there are 34 different Hagezi list. So it will take some experiments to pick a "the" list.
Also, here is current DRAFT (first draft) of user/admin managed WebGUI. See attachment.

Does this help? Jon

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?

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

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`?
