PfBlockerNG v2.0 w/DNSBL

Panja

I used DNSBL before but have disabled it at the moment.
Is it correct I can still ping the virtual IP address (default: 10.10.10.1) even after disabling DNSBL?

[UPDATE]
I uninstalled pfBlockerNG and unticked the box that says "keep settings".
After that I re-installed pfBlockerNG and configured everything without enabling DNSBL.
The virtual IP assigned to DNSBL is not pingable now. I "fixed" the problem myself. 8)

Got a crash report running on 2.3.2-RELEASE (i386) with pfBlockerNG 2.1.1_2 with only DNSBL setup according to advise #18 (https://forum.pfsense.org/index.php?topic=102470.15), btw having enabled Alexa with 1K set.

Thanks for any help/advise cheers Qinn

Can you run from Shell

php /usr/local/www/pfblockerng/pfblockerng.php dc

That will download the latest MaxMind as it did that yesterday (first tue of each month). Looks like you may have ran out of memory. How much memory do you have in the box?

You can also look in the Firewall/pfBlockerNG/Log Browser at the extra.log or pfBlockerNG.log file.

Took a look at the code with:

sed -n '720,740p' /usr/local/pkg/pfblockerng/pfblockerng.inc

but can't see anything strange?

Second, I followed your advise, here are the results, btw Memory size = 1Gb (1024) usage 18%, during the process below I noticed that Memory usage rose from 16% to 28% and dropped to 17% after the error occurred, as shown below. It seems the process eats RAM and somehow there is a max set for the process.

I have an identical situation except the line "(tried to allocate 20 bytes)" reads 27 bytes. Also, the PHP Errors block repeats itself a few times.
I tried to reinstall pfBlockerNG through the package manager, it claimed to have reinstalled but it no longer shows under the Firewall menu of pfSense. I uninstalled and reinstalled in two steps, again using the package manager, same result. For now I removed the package. My hardware is based on 32 bit N270 and I have 1GB of RAM, tons of HD space.
Prior to upgrading pfSense to 2.3.2 everything worked flawlessly for over a month so I assume that it has something to do with pfSense upgrade. I don't recall when I got pfBlockerNG upgraded.
I hope mine is not an isolated case.

1GB might be too small since the last MaxMind database change. Can you put more RAM in the box?

I have 2.5GB on my pfsense and I got a crash report :o
This looks like a change at some point in the MaxMind db. So be patient until BBcan177 take a looks at this.

Maybe it is too late, but did you get any errors while removing or installing pfBlockerNG?

Qinn

Although today 1GB Memory isn't much, maybe the dev's (BBcan177) could be encouraged ;) to find a solution as the pfSense recommended requirements are (https://www.pfsense.org/hardware/) RAM - 1 GB. So I put in a extra 512MB (so now 1,5GB), but I am shit out of luck, again error. Should have guessed it, as even your 2,5GB wasn't enough.

Qinn

Hmmm, I have searched the forum and this error has occurred many times, and never the solution was to increase memory:

I get these messages Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 36 bytes)
from time to time with other function in pfsense, when viewing big file or with backup.
And I never found a solution for these.

I disabled pfBlockerNG, DSNBL, surricata, reboot, close all pfsense tabs.
This gives me around 1.8GB of free memory, and the pfblockerng.php dc still crashes.

Is there someone with more than 2.5GB of memory that doesn't have crash when updating the MaxMind GeoIP db ?

@oswoldy:

Hi,
I get the crash with 8GB of RAM :(

I guess I won't bother installing any more than the 4GB that I currently have installed. I have disabled pfBlockerNG for the time being.

Gerard64

Same here with 4gb ram.

I tried to reinstall Pfblocker but no luck now it doesn't even show up anymore under Firewall menu item.
Before I reinstalled it hanged constantly on update the lists.

RonpfS

Well during installation pfBlockerNG download the MaxMind GeoIP database … it probably crashes and the installation doesn't complete. :o

q54e3w

do you see stability if you reduce the number of lists you have active? My 16GB runs along fine at 40% utilisation with a fair few lists thrown at it and I recall from my casual observation it uses more whilst it processes them too.

No, there was no error messages during the reinstall, removal or installation. But, the weird thing is that although pfSense said the installation (or the reinstallation) was a success, pfBlockerNG was nowhere to be found; in the menus nor in the service status, watchdog, etc. So, I assume that it didn't install properly. But the dashboard says that only 20% of the RAM is used, so I doubt that this is a memory issue. Plus, I have been using pfBlockerNG on this same hardware for some time, so unless the last version has changed something drastically 1GB has been fine.
Meanwhile, I restored a raw copy backup of my system prior to 2.3.2 upgrade. That works like a charm. It has pfBlockerNG 2.0.17 on pfSense 2.3.1-p5 (i386). PfBlocker definitely works as it blocks access to and from China, Russia, etc.
So, until the dust settles oldies are the best way to go for me.

Gerard64

Here is always worked fine with my 4GB of ram but since the last update it started to give problems i disbaled PFblocker for now and wait maybe it get fixed if not then i gave to sadly uninstall uninstall.

RonpfS

Here is a fix for the MaxMind errors https://forum.pfsense.org/index.php?topic=116307.msg644910#msg644910
please use that thread for this issue

Above tip of Ronpfs worked.
But after the last re-install of pfblocker it didn't reinstall correct. It doesn't show up in the menu and it gives a error at the end of the reinstall.

pkg: POST-INSTALL script failed

Is there a way i can install a previous version of pfblocker?

I do not think you can revert to a previous version :(
And even with the previous version it would be the same as the change comes from MaxMind GeoIP change, not from pfblockerNG code.
