PfBlocker

BBcan177

This doesn't work, because I can't get an "md5 -s" of a list that changes every day (or more often) and compare it to an older version. Am I missing something?

The md5 is based upon the URL name. Does your URL change? My guess is that it is consistent, so you should be able to run that command and it will calculate the md5. This will allow you to see which filename in the directory matches your URL.

This is not related to your problem as its a PHP Memory Error.

@stephenw10:

The limit you are hitting '262144000 bytes' is that imposed on the pfblocker process by the line at the start of the pfblocker.php file:

Steve, what limits would you expect would be appropriate for pfBlocker for various Hardware?

stephenw10

I have no idea. I only spotted that because the limit is 250MB rather than 256 which I might have expected. There appears to be another overall limit in the suhosin config in php.inc of 512MB.
I know pretty much nothing about php. ;) 250MB seems like it should be fine. My home box only has 512MB anyway. A better question might be does the fact that it's used 250MB seem reasonable?

I have "splitted" my (big) list: now each I-Block list matches one pfBlocker list (with Alias_only) selected (see attached screenshot). Lists are set on I-Block URL to be in CIDR.

I'm still receiving this error message when I try to start pfBlocker

Fatal error: Allowed memory size of 262144000 bytes exhausted (tried to allocate 18 bytes) in /usr/local/pkg/pfblocker.inc on line 253

This is 2.1.4 right? 2.2 Alpha will fail loading/updating these lists, that has been reported and they are working on it. Another thing is a lot of those lists duplicate each other, ie. have the same IP's in the lists.

Read this thread:https://forum.pfsense.org/index.php?topic=78062.0

Remove Prime, it is a combination of several the lists you already have as aliases and is not needed, read the description of Prime. Prime might be the problem since it itself is absolutely huge… If removing Prime doesn't help then:

Back up pfBlocker.inc then Look for a line in the pfBlocker.inc that looks something like this:```
if ($uname['machine'] == 'amd64')
ini_set('memory_limit', '256M');


Change the 256M to 512M and see if that helps.

Thank you @wcrowder for the fast response. I don't like any list in particular: I wanted to test each of them with a firewall rule for each list so - by analyzing the logs - I'll be able to keep the lists that hit the blocking rule the most of times.

I can't still believe that a Unix OS can't handle a simple task like this: as I wrote in this thread, my stupid Windows 7 machine with the same amount of RAM can load ALL those lists in PeerBlock FAST! And it works flawlessly, blocking and notifying 24/7.

You can not compare pfSense to Peer-block, in comparison Peer-block is truly useless. How may Windows 7 machines act as firewalls to large networks, do you wonder why? pfSense is. Did you follow through the link to the thread I sent you above? Follow the instructions, remove the duplication? Here, I'll give it to you again: Read this thread:https://forum.pfsense.org/index.php?topic=78062.0

Yes, I removed the duplicates: I logged into pfSense with WinSCP and manually deleted those jsjdjdjjdjjddkkakirtitjjf.txt files. Then I deleted the pfBlocker package and all the files in the upper pkg dir that contained the word pfBlocker.

Strangely enough, after pfBlocker reinstallation, all the lists were still there, listed in the GUI, so maybe do I need to purge other files?

wcrowder

The xx.txt files need to be there. They are the county code files for country blocking. The duplicates I was talking about are IP's in the lists. Example: On the iBlockList website the iBlock Prime list already includes the US Government, Malicious, Piracy Related, Pornography, Ads and Trackers and Proxies lists so when you add Prime AND those lists you have DUPLICATION that you don't need…

Ok, I'm going to dedupe the lists. Where is the lists' list stored? Even after a package reinstall, the list is there.

Supermule

Could we make a pfblocker community so we easily can share files and lists?

Maybe from within the package itself?

panz

I'm emailing to I-Blocklist maintainer to ask him if he could implement a deduplication feature in the customized lists section. For now, I'll be happy if the pfBlocker package could handle a memory increase by itself. I don't want to mess with file editing in an appliance.

Supermule

Not a bad idea.

Just wait for a pfBlocker update… ::)

Is MArcello still developing this?

It is being very actively forked, we will just have to wait for an announcement from the author doing the update… Or, you could read this thread more carefully. ;D Did you read the thread I posted to you Panz? :-*
