PfBlocker

[marcelloc]

I' ve tested virtualbox + pfsense 2.0 amd64 embedded kernel with no issues.

I'm not sure if embedded kernel will work the same way nanobsd on Compact Flash 2 Gb will do.

I found some posts on forum saying that is not easy to run nanobsd img on virtualbox, but I'm still trying..

hubsd,

Second test, first problem:

I've changed /etc/platform to nanobsd.
after a reboot mount -a returns:

/dev/ad0s1a on / (ufs, local, noatime, read-only, synchronous)
devfs on /dev (devfs, local)
/dev/md0 on /tmp (ufs, local)
/dev/md1 on /var (ufs, local)

So, read-only file system.

installed and configured pfblocker with no issues.

after a reboot,
I got the same error:

php: : The command '/sbin/pfctl -o basic -f /tmp/rules.debug' returned exit code '1', the output was 'no IP address found for grep: /tmp/rules.debug:15: file "/var/db/aliastables/pfBlockerTopSpammers.txt" contains bad data pfctl: Syntax error in config file: pf rules not loaded'
php: : New alert found: There were error(s) loading the rules: no IP address found for grep: /tmp/rules.debug:15: file "/var/db/aliastables/pfBlockerTopSpammers.txt" contains bad data pfctl: Syntax error in config file: pf rules not loaded The line in question reads [ /tmp/rules.debug]:
php: : There were error(s) loading the rules: no IP address found for grep: /tmp/rules.debug:15: file "/var/db/aliastables/pfBlockerTopSpammers.txt" contains bad data pfctl: Syntax error in config file: pf rules not loaded - The line in question reads [ /tmp/rules.debug]:

But, without saving any new config, I've looked at diagnostics-> table and pfBlockerTopSpammers was filled up normally, alias was there and firewall rules too.

So, Isn't it just a 'until boot finishes issue'?

Can you check if it happens the same way on your installation?

I know system alerts are annoying and have to be fixed but if package is still working, isn't it a minor issue?

Second problem:
boot takes 3 to 4 minutes.
it's a problem in fetch call that has no time out(or 01:15 timeout), I'll include a timeout patch to pfsense-tools.inc file on next release.

[hubsd]

Quick update, i exported my nanobsd config and imported it in a microdrive + classic embedded installation (so no nanobsd)

I can confirm that I have zero issue now and boot time takes 2 minutes.

So the problems I noticed are only while using nanobsd.

Just saw your answer, well the problem is only until boot finishes issue yes ! It slow down boot time + spam warning messages. pfBlocker works fine so yes it's not a major issue and is because of nanobsd …

[marcelloc]

Version 0.1.4.2 includes fixes to 3-9 minutes boot on embedded systems.

[hubsd]

thanks !

just installed pfsense and this tonight…. getting emails of this:

There were error(s) loading the rules: /tmp/rules.debug:17: cannot define table pfBlockerAfrica: Cannot allocate memory
/tmp/rules.debug:19: cannot define table pfBlockerAsia: Cannot allocate memory
/tmp/rules.debug:21: cannot define table pfBlockerEurope: Cannot allocate memory

pfctl: Syntax error in config file: pf rules not loaded The line in question reads [17]: table <pfblockerafrica>persist file "/var/db/aliastables/pfBlockerAfrica.txt"

:( how do I fix?

edit just figured out how to up my tables size. Upped it to 100mil.

I'm testing the ad blocking lists and they aren't blocking anything. All I've done was add the lists and tell it to deny_inbound. Is there anything else I should be doing to make this work? Thanks.

Also if anyone knows of any great ad lists to help me block all the advertisements I possibly can please do let me know! :)</pfblockerafrica>

[marcelloc]

While blocking adwares, proxies, spywares the default way is outbound

Take a look in ipblocklist, the are many lists there.

Also pay attention on direction.
If you want to do not access somewhere, the action is deny outbound.
If you want that someone in somewhere do not access your network, the action is deny inbound.

If 100mil means you Speaker portuguese, there is also a pfBlocker topic in portuguese forum.

I'm American. Thanks for the clarification. I was up till 3am last night playing with this, tweaking and fixing several small issues. Still got a few left, but so far I am amazed at pfsense. This is way better than Mikrotik for my needs and its FREE. :)

Yea the quality of this package is outstanding, if i had money, i would donate to it. :D honest.

One feature request would be send all blocks to a new tab in the system logs status page called pfblocker and then have the ability to quickly add blocked ips to whitelist. Also a blocked log widget similar to the firewall logs one also.

Thanks for that, our main goal is write package that improves pfSense quality and help daily admins tasks.

I can't be done until pfsense has a way to choose log direction or prefix.

pfblocker just help alias and rule creation.When you check enable log, it include rules with log enabled.

[sekular]

OK that makes sense. I guess adding a easyrule rule: pass from firewall will do the same thing.

I do not have xmlrpc sync enabled but i am getting this in syslog after update list jobs.

it's just a print before if

not a big deal.

never mind If you do not have checked sync option.

My alias keeps getting knocked up to the top of the rule sets I have for my networks (I have a LAN and WLAN network). It's been happening erratically. I'm not sure what is causing it or what to do about it.

My pfBlocker rule won't stay in the order that I have here. It moves to the top and ends up blocking a lot of traffic my rules allow.[/move]

[marcelloc]

If you need custom rules before pfBocker, you must change pfBlocker action to alias only and then create your own block rules.

A shortcut to this is changing pfBlocker applied rules description before changing action.

[Quinn1981]

Makes sense. :)

Hey guys I'm new here and to pfsense. I noticed that when I enable pfblocker my wireless clients can longer connect to the internet but my wired. Any ideas. I'm using a linksys wireless router with dd-wrt loaded on it. It has worked forever until I enable pfblocker without any rules created. I'm a complete noob to linux/unix. Thanks in advance!!!

[marcelloc]

PfBlocker does not remove or include any rule different from its own rules.
Try disabling it and see what happens.

Also try to include some lists and see how it include aliases and rules.

[RonpfS]

You might add something about the rule being under pfBlocker control in the rules description.

[marcelloc]

Don't you think pfBlocker Inbound/outbound rule description is less robotic?  :)
