PfBlockerNG v2.0 w/DNSBL

nikkon

/usr/local/pkg/pfblockerng/pfblockerng.inc

pfb_global();

// DNSBL Lighttpd HTTPS Daemon (Scans Lighttpd dnsbl_error.log for requested https domain names)
if (isset($argv[1]) && $argv[1] == 'dnsbl') {
set_time_limit(0);
pfb_livetail($pfb['dnserrlog'], 'dnsbl');
exit;
}

and i guess is default.

and also usr/local/www/pfblockerng/pfblockerng.php - not modified.

RonpfS

And no modifications to /etc/inc/config.inc or /usr/local/etc/php.ini, /etc/rc.php_ini_setup ?

nikkon

well based on my comments i did one to the first file:
// Set memory limit to 512M on amd64.
if ($ARCH == "amd64") {
ini_set("memory_limit", "512M");
} else {
ini_set("memory_limit", "256M"); # increased from 128M
}

This change only affect i386 systems, you are on a amd64.
Did you raise the System / Advanced / Firewall & NAT Firewall Maximum Table Entries ?

nikkon

no
will do now. what's a starting value?

i had 5000000 now i have 50000000

RonpfS

I think 2000000 is the default, 50000000 should be more than enuf.
Do you see the pfblockerNG menu ?
BTW how much free memory do you have ?

nikkon

still not there.
i have deleted, restarted, reinstalled pfbloker.
27% of 8130 MiB free ram

I changed the mem settings and the table settings and now I'm getting

same line on which i have the crash reported

Again which memory settings did you change ?

In this thread there was a fix for pfblockerng.inc that will NEVER work on installation as the file is overwritten during the installation of the package.

It is good practice to disable pfBlockerNG AND DNSBL before removing or re-installing pfBlockerNG or before upgrading pfsense.

So to reinstall of a i386, in Diagnostics / Edit File open /etc/inc/config.inc,
go to line 77 and change from

// Set memory limit to 512M on amd64.
if ($ARCH == "amd64") {
   ini_set("memory_limit", "512M"); 
} else {
   ini_set("memory_limit", "128M");
}
```to

// Set memory limit to 512M on amd64.
if ($ARCH == "amd64") {
ini_set("memory_limit", "512M");
} else {
ini_set("memory_limit", "256M"); # i386 Default 128M
}


If the installation fails to complete on a **amd64** system, then you need to change /etc/inc/config.inc (line 75) from 512M to 640M or 768M.

// Set memory limit to 512M on amd64.
if ($ARCH == "amd64") {
ini_set("memory_limit", "512M");
} else {
ini_set("memory_limit", "128M");
}

// Set memory limit to 512M on amd64.
if ($ARCH == "amd64") {
ini_set("memory_limit", "768M"); # amd64 Default 512M
} else {
ini_set("memory_limit", "128M");
}

**AND** modify the /usr/local/etc/php.ini (last line) and /etc/rc.php_ini_setup files (line 303) from

suhosin.memory_limit = 536870912

to

suhosin.memory_limit = 671088640 # 640M Default 536870912

or

suhosin.memory_limit = 805306368 # 768M Default 536870912


If you use many GeoIP IPV6 tables (like those who block the world, again this is not the _optimal_ way to configure a firewall), then you will have to raise the **Firewall Maximum Table Entries** until the FW rules loads.

Check the installation logs,  Dashboard for crash report, /var/log, /var/log/pfblockerng, etc

nikkon

ok if i do allocate 768M as mem limit, whats the value to be changed on suhosin.memory_limit in php.ini?

RonpfS

You have to edit the /usr/local/etc/php.ini, /etc/rc.php_ini_setup files to

suhosin.memory_limit = 805306368

nikkon

no more crash reports after reinstall.
pfblokerNG back in the menu.
all back to normal !
thanks for helping :)

what was the file path for config.inc

RonpfS

/etc/inc/config.inc
I updated the previous post.

@RonpfS:

You have to edit the /usr/local/etc/php.ini, /etc/rc.php_ini_setup files to

suhosin.memory_limit = 805306368

I'll try the rc.php_ini_setup when I get back home.

I changed to this(I'm running on a 64bit system)

// Set memory limit to 512M on amd64.
if ($ARCH == "amd64") {
ini_set("memory_limit", "768M");
} else {
ini_set("memory_limit", "128M");
}

Thanks it worked!!

Hi all,

I'm also having this issue. However, I don't know where you guys are finding the file to edit. I see that the location of the file is /etc/inc/config.inc but how do I get to it to edit? I'm only familiar with pfsense through the web interface.

Thanks in advance for your help!

Maybe you should read this https://forum.pfsense.org/index.php?topic=102470.msg647719#msg647719 again

I made the mistake to reinstall the pkg. ( didn't take a snapshot before doing it) But I have a backup of the machine that I could restore and boot up.

My idea was if it could be done to export the settings from the backuped VM ( running ) and import it in my live system?

I can't find any way to extract the settings. found a way to sync the settings could try that but export import would be easier I think.
