pfBlockerNG-devel v3.0.0 - No longer bound by Unbound!

This post is deleted! -
Since the update to 3.0, cpu usage went down considerable, also the sg-3100 temps.
Really nice work..

Hi BBcan177,
Thanks for the 3.0 release!
I'm currently not using the Python module since I have unbound views set up to only include the DNSBL configuration for certain subnets. However, I also have a custom Python module loaded to filter out AAAA responses from a number of Netflix domains and subdomains (works around an issue with IPv6 tunnelbrokers being blocked by Netflix as proxies).
Presently, when pfBlockerNG-devel is set to Unbound mode it resets my Unbound Python module settings every hour when it refreshes. Is there any way to get it to coexist with my own Python module and remain in Unbound mode? (I understand that this will preclude me from using the pfBlockerNG Python module in the future since pfSense's unbound configuration only supports one Python module, but for the moment I'd rather live with that limitation and use pfBlockerNG in Unbound mode while maintaining my current custom Python configuration).
Thanks!

This is what you can do : edit : /usr/local/pkg/pfblockerng/pfblockerng.inc : lines 2025 and up :
// Remove python settings from DNS Resolver configuration if (isset($config['unbound']['python'])) { // unset($config['unbound']['python']); // $config['unbound']['python_order'] = ''; // $config['unbound']['python_script'] = ''; $log = 'KEEPING DNSBL Unbound admin added python script';Add in front of lines 2027 - 2028 - 2029 the "//"
Change line 2031 so it shows a text in the update log what it is doing.So, 4 lines need minor editing. The last one is even not strictly needed.
Now your unbound python settings like :
persists when pfBlockerNG 'does it things'.
Your own no-aaaa script gets loaded by unbound as before :
This line shows in the log because I modified the original no-aaaa script to show this line at init/start of the script.
When "views" gets integrated into pfBlockerNG, you should be able to switch to the new Python mode, uses views and use the build in 'no-aaaa' facility.
See this as a temporary patch that gives you the possibility to use your own no-aaaa script while you use pfBlockerNG in unbound mode != python mode.
Right now, true, if pfBlockerNG is put in unbound mode, it removes / deactivates unbound own python settings. -
@axellarsson Or use the Python mode with no AAAA setting

@BBcan177 thanks for this release. I just installed it. Looks like it is working BUT in the reports tab suddenly Source and IF is "unknown" which was not the case before the upgrade. Any idea?
I am on pfsense 2.4.5 and pfblocker-ng 3.0.0_7

pfSense 2.4.5 uses Unbound v1.10.1 which has a regression that fails to pass some information to the python modules. It has been fixed, but there is no way to upgrade Unbound to v.1.12.0 in pfSense 2.4.5.
In pfSense 2.5, it has Unbound v1.13.0.
For the DNSBL Blocking part, you can enable the checkbox in the DNSBL Tab > DNSBL Event Logging , and that will stop the python integration from logging, and use the DNSBL Webserver to log the events. Unfortunately, that is only limited to HTTP events.
And for DNS Reply logging, there is no other workaround.
Not much I can do unfortunately.

@bbcan177 Thanks for the prompt reply.
I am willing to experiment but from what I just read 2.5 is not that close to be production ready (or is your experience different?).
Sad that no solution exists for upgrading unbound but that is not you fault of course. I changed to DNSBL Event Logging. What are typical "non http events" and am I missing them completely then (which would make debugging quit interesting).
What do you mean with DNS Reply logging?
Sorry for the stupid questions.

pfSense 2.5 is nearing RC status.

Sorry for the stupid questions.DNS Reply logging will not show the Source IP/Hostname in pfSense < 2.5 as there is a regression in Unbound.

@bbcan177 I might have found a bug with IPv6 DNSBL. When I have it enabled, it creates a VIP on the LAN interface, but it seems to block the ability for "track interface" to work. If I disable IPv6 DNSBL, the LAN gets an IPv6 address as expected.
-
@bruor
Set the DNSBL Interface to use "Localhost" -
@bbcan177 Awesome thanks!

Anybody an Idea why the pfb widget stopped to count the total queries resolved by unbound since v3.0.0? I'm currently running v3.0.0_7.
-
@artes said in pfBlockerNG-devel v3.0.0 - No longer bound by Unbound!:
v3.0.0_7.
Upgrade .... 3.0.0_x versions are "work in progress".
3.0.0_8 for me right now :
edit :
This
that there are no lists / feeds loaded, so it's normal nothing else is listed.
If have 5 list loaded - with 1968 unique IP/DNSBL.
No "help me" PM's please. Use the forum, the community will thank you.
Edit : and where are the logs ?? -

3.0.0_8 for me right now :The last one was a Copyright update : https://github.com/pfsense/FreeBSD-ports/commits/devel/net/pfSense-pkg-pfBlockerNG-devel

If there were no feeds the blocked counter wouldn't be at ~250k ;-)
here is a screenshot of my full widget
-
Just noticed that with this setup I get DNS SERVFAIL responses if pfBlockerNG matches. Should this not point to the virtual IP so that an error page has chances of being displayed? I am probably missing something.

Hey @BBcan177 we already talked about that back when we exchanged mails but: Are you planning on switching trees with the upcoming 2.5 release? Make 3.0.x finally the stable version and go on developing in the devel branch again, so the customers can have a "stable" version again?
I get asked about that over and over and over and with all the changes in the devel up to 3.x I think it would be time to switch it back to stable so people finally ditch the "oldstable" and get the new one which would make support easier, too :)
What are your plans on that? And can we perhaps get together again about the whole HA/CARP thing?
Best wishes!
Cheers

Hi,
I'm on pfSense 2.4.5 and pfBlockerNG 3.0.0.8.
After enabling the Unbound python mode for DNSBL and doing the Force Reload-DNSBL Unbound Resolver was stopped and did not start again.
