PfBlockerNG v2.0 w/DNSBL

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.

@RonpfS:

@haleakalas:

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.

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

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.

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.

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.

Can you try https://forum.pfsense.org/index.php?topic=115966.0

Gerard64

Thank you again Ronpfs.
I did what you suggested on that other thread it did not work. I increased to 750M but no joy :(

Solving the problem by throwing more memory at it worries me a bit. I hate to sound old-school, but 1GB or RAM on a router/firewall is a lot of memory. Allocating upwards of 300MB for one particular function, if that is on exclusive basis, would worry me that the implementation of that function is less than optimal.

As for the installation issue, it is still there. I can no longer install the latest version of pfBlockerNG; although pfSense claims that it's installed it doesn't show anywhere in the menus.

The patch was made for someone with pfBlockerNG installed. You could probably revert it.
I posted another similar patch for the case when pfBlockerNG isn't installed.

We are just trying to get a fix until BBcan177 can find a proper fix when he comes back.

pfBlockerNG with DNSBL requires load of memory as it handle 1M+ table. So 1GB is really not that much memory for this kind or usage.

Oke I tried that mod and went up to 1500M but no success I can't install Pfblocker.
Oh and BTW i have a 64bit system with 4GB ram.

Well it doesn't fail at the GeoIP step …

can you run from the shell

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

then try the reinstall ?

Gerard64

Sadely no success.
Still the same problem :(

It looks like you are on a x64 system … so it maybe related to something else.

Sorry didn´t saw you pm me.
Gonna do that now what you suggested in the pm.

Thanks @RonpfS setting the memory_limit on line 236 to 300M fixed it. :)

@RonpfS:

@wiz561:

Thanks for the response. Are you saying that I should change the…

Firewall Maximum Table Entries: 2000000

to

Firewall Maximum Table Entries: 4000000

I just wanted to make sure I'm changing the right thing.

This looks like it ;)
Firewall Maximum Table Entries : Maximum number of table entries for systems such as aliases, sshlockout, snort, etc, combined.

@wiz561:

Also, when the cron jobs were running, I saw something with some large numbers of maybe the 200000 and I was at something like 150000… Sorry I didn't make note of it.

Thanks!

You can review the log file by going to the Firewall/pfBlockerNG/Log Browser tab

Thanks. I saw that 20000 number get changed to 40000-something so I think it's working. Hopefully this will fix it!

I've been having some issues lately so I'm hoping that maybe this clears up some of the problems. I think it's snort related, as the problems ceased when I stopped snort for a few days.

Hi! I've been having another strange problem. I modified that parameter to the 40000-something the other day and rebooted pfsense. It's been running OK now for maybe 3 or 4 days and this-morning, I am receiving the same message and a crash report…

On the dashboard, I have "49% of 2gb" for the memory and 0% swap used.

I'm wondering if my pfsense install is borked because it's been running kind of slow and php-fpm has about 90% utilization when browsing the web interface after an upgrade.

wiz561

I'm actually going to move over to the memory posting in this forum since it sounds like there's others with similar issues…

I'm giving another go.

Yet, still nothing shows up under the Firewall menu, but I keep going with the following steps:

Diagnostics/EditFile : /usr/local/pkg/pfblockerng/pfblockerng.inc
Search for:
"pfb_global();

// DNSBL Lighttpd HTTPS ..."

Insert "ini_set('memory_limit', '300M');" on the empty line.

Save the file.

Diagnostics/CommandPrompt/Shell : php /usr/local/www/pfblockerng/pfblockerng.php dc

Let it crunch for a while, browser timeout so I can't see the result of the php command!
Wait another 10mn and relogin into pfsense. pfblockerng still not in the menu.

Reboot pfsense with hope that it will show up.

But it doesn't. Find error message in the system log file:
"rc.bootup: New alert found: There were error(s) loading the rules: /tmp/rules.debug:35: cannot define table pfB_Europe_v6: Cannot allocate memory - The line in question reads [35]: table <pfb_europe_v6>persist file "/var/db/aliastables/pfB_Europe_v6.txt"

I tried the whole thing with 500MB, still the same result.
What else to try?

Is there a way I can "force" the menu to show up pfblockerng. If I can access it I could at least turn on the package logs and get maybe more info on what's going on deep down…</pfb_europe_v6>
