PfBlocker
-
I am receiving an error:
Dashboard page - pfBlocker widget
it is reading '500 - Internal Server Error'This is also reported here:
http://forum.pfsense.org/index.php?topic=54262.0running: 2.0.2-RELEASE (amd64)
packages:
OpenVPN tap Bridging Fix
pfBlocker
RRD Summary -
Upon investigating another error I was experiencing, see here:
http://forum.pfsense.org/index.php/topic,57113.0.htmlI switched from Chrome to IE, in IE the 500 error is gone and the dashboard widget works as expected.
Maybe the pfBlocker and Traffic Graph bug are related….. both show errors in Chrome but work in IE

I get this error
php: : There were error(s) loading the rules: /tmp/rules.debug:39: cannot define table pfBlockerEmerging_Block_IP: Cannot allocate memory pfctl: Syntax error in config file: pf rules not loaded - The line in question reads [39]: table <pfblockeremerging_block_ip>persist file "/var/db/aliastables/pfBlockerEmerging_Block_IP.txt"
I have deleted the file, but it still shows up on the pfblocker widget on the frontpage of PFsense.
It keeps giving me errors of the list is gone, but before I deleted it, it was still there.
Very weird problem…</pfblockeremerging_block_ip>
-
Cannot remove lists from pfblocker widget….
How to do?? They dont go away when deleted from the lists tab in the config GUI.
-
Deleted and reinstalled. Lists are gone.
-
Did a package delete and rebooted….

I think it has issues with 2.0.2 release…..</pfblockertopspammers></pfblockertopspammers>

Did a manual delete in rules.debug to remove pfblocker aliases.
Now it says this…

Looks like memory allocation errors.
Did you go to system > Advanced > Firewall/Nat tab and increase the Firewall Maximum Table Entries?
I have had to increase mine quite a bit to run all my tables. I currently have mine set to 999999999 and no longer get any memory allocation errors.
-
Its currently set at 200.000 table entries…and 100.000 tables...
-
increase it way up. Thats most likely the problem. Its not going to affect the firewall negatively. You see where mine is set and all runs just fine and I dont get those errors anymore.
-
Whats your maximum tables and table entries??
-
Attached everything on that page. I didnt touch anything else. Left it at default.
-
Thx!
-
Love it! :)

I have pfBlocker loading a list from the following url:
http://www.dnsbl.manitu.net/download/nixspam-ip.dump.gzI decompressed the .gz to look at it and found text in the following format:
2013-01-21T20:15+0100 78.39.223.180 2013-01-21T20:15+0100 49.202.135.218 2013-01-21T20:15+0100 213.108.75.31 ...I have 2 systems that handle this list fine.
One other system scrambles the file content - loads nonsense IPs the table - is why I peeked inside the .gzThe thing is, I thought pfBlocker had to have the IP addr/cidrs at the beginning of the line. Looks like I'm wrong.
In what format(s) does pfBlocker need it's IP data?

It loks for ip addresses using preg_match, if you can edit it to remove ip date, it may help.

The list loads fine on two systems; now I know why.
The system that scrambles the data has 27 lists loaded.
It's probably just reacting to all the abuse I heap upon it.As always, thank you for your insight.

The real main issue is even on last update 2.1-BETA1 (today), pfblocker still doesn't comes up as ENABLED.
Everytime after update I need to go there and manually enable myself. ::)

Pfblocker uninstall script will always disable the service to avoid aliases/rules issues.
It's a feature, not an issue ;)

Hi, I added support to insert portlist file. this way peoples can customize installations with pre defined rules from their web sites.
you can deploy port list file with adding #PORT_LIST_PF text to begin of file.
i hope you will include this changes to next release and it will helpful to others.
example port list file: safeports.txt
#PORT_LIST_PF 21#ftp 22#ssh 25#smtp 53#dns 67#dhcp 80#http 110#pop 443#https 587#new smtp 1433#sql server 3306#mysql 3389#rdpreplace bellow code in your /usr/local/pkg/pfblocker.inc
add this function to after pfblocker_Range2CIDR function
function pfblocker_Range2Ports($port_min, $port_max) { #function called without any args if ($port_min == "" || $port_max == "") return ""; #function called with same ip in min and max if ($port_min == $port_max) return $port_min; $bas=intval($port_min); $start_port+=1;//skip first value because its already processed $res=""; $end_port=intval($port_max); for($i=$start_port;$i<=$end_port;$i++) { $res.="$i\n"; } if($res!="") return $res; }changes begins at "#print $list['aliasname'].$list['action']."
