PfBlocker

[marcelloc]

Hi tommyboy, do you have a list newer then the latest provided by country block? ???

[SamSquanch]

Ok, so I found out today that pfBlocker thinks www.facebook.com or 173.252.100.16 is in Europe somewhere.

So now my question is how do I get my hands on the lists that pfBLocker is using so I can view them in the raw format?

And if I edit that file/files can I replace the current ones by hand?

Thanks.

I don't think it's newer but it's reliable. I've been using it this whole time.

So I tried to search some but too many pages lol.

On the widget, what determines the "Packets" count?

Initially I thought it would keep a rolling count of blocked packets but it seems to go up and down. Like right now it says 6 but in a few min it will say 0.

I feel kind of dumb asking because I'm sure it's answered some place obvious.

Everything I could find makes me think rolling count but why would it go to 0 so often, shouldn't it keep growing if anything?

FWIW I am on 2.1 latest snap.

Mine does this also.  At first I thought it was because I occasionally clear my firewall logs. But it just happened and coincided with a modem going down and resetting which has started to happen here.  Will keep watching unless anyone else knows.

Anytime interfaces are reset, brought down ect will reset the counters. If you run snort and it does an update to the rules, it will flush the counters.. There are many things that will reset it. I am not sure what other packages you are running but this could lead to the counters clearing as well.  Its not a big deal to me. As long as its up and running is all that matters. :-D

Some of that makes sense but in my case I have only that one package running and can just simply keep the home page up for 5 min and often it will reset to 0, or simply just hopping around in the menus, say I look at some logs, double check vpn status etc and later go back home (not making any actual changes during any of this) it will be reset.

I agree it's not a super big deal but kind of defeats the point of the widget to me as that is what I was interested in about it. I rather not have to parse through logs to see if all the sudden my box is getting a big hit from trouble makers.

Don't get me wrong though. I am grateful of the app and still learning it and other options but is a bit of a tease lol

[kilthro]

check you logs. are you getting reset interfaces? is there any other activity causing this? If you change settings in other areas that can affect the interfaces or monitoring ect it will cause them to reset. I wonder if you are getting alarms on these interfaces.. I never have the widget reset buy just moving around in the webgui.. only if i actually make changes to interfaces, pfblocker, snort, ect..

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=54262.0

running: 2.0.2-RELEASE (amd64)
packages:
OpenVPN tap Bridging Fix
pfBlocker
RRD Summary

[ccb056]

Upon investigating another error I was experiencing, see here:
http://forum.pfsense.org/index.php/topic,57113.0.html

I 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>

[Supermule]

Cannot remove lists from pfblocker widget….

How to do?? They dont go away when deleted from the lists tab in the config GUI.

[Supermule]

Deleted and reinstalled. Lists are gone.

[Supermule]

Did a package delete and rebooted….

[Supermule]

Did a manual delete in rules.debug to remove pfblocker aliases.

Now it says this…

It just wont go away!</pfblockertopspammers></pfblockertopspammers>

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.

[Supermule]

Its currently set at 200.000 table entries…and 100.000 tables...

[kilthro]

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.

[Supermule]

Whats your maximum tables and table entries??
