Country Block

@tommyboy180:

@JackANSI:

When you check "Enable Logging?" in the settings page, where is it being logged to?

The firewall tab under system logs.

Thought so. Then:
A. I'm getting no traffic at all from any of the top spammers,
B. Country Block isn't running even though it says "Running…. Blocking 11110 Networks",
C. Logging isn't working right for me somehow, or
D. The only traffic I have heading my way is being handled by the 28 rules I have on my TWAN interface already.

Are the country block rules before or after any rules we already have under the regular firewall rules? Because a few of the ranges I excluded manually a long time ago show entries in the firewall log every 5-10 minutes.

Might this be related to my config and country block isn't compatible with it? I'm running 1.2.3, I have 2 WANs, one T1 and one cable modem. The T1 is where I want country block (and it is selected alone under "interfaces") as it is where the servers reside. The T1 also has 5 IP addresses assigned statically. The cable modem handles all the client/user traffic and is the 'real' WAN port. There are also 6 other interfaces on this machine.

In my config file I have the following being applied to that interface (the only way I could get this interface working right):

<shellcmd>/sbin/ifconfig fxp2 #.#.#.203 netmask 255.255.255.255 alias</shellcmd>
<shellcmd>/sbin/ifconfig fxp2 #.#.#.204 netmask 255.255.255.255 alias</shellcmd>
<shellcmd>/sbin/ifconfig fxp2 #.#.#.205 netmask 255.255.255.255 alias</shellcmd>
<shellcmd>/sbin/ifconfig fxp2 #.#.#.206 netmask 255.255.255.255 alias</shellcmd>
.....
<opt2><if>fxp2</if>
<descr>TWAN</descr>
<bridge><ipaddr>#.#.#.202</ipaddr>
<subnet>29</subnet>
<gateway>#.#.#.201</gateway>
<spoofmac><mtu><enable></enable></mtu></spoofmac></bridge></opt2>

I'm working on a little script that will just take the content of the files from countryipblocks.net and just creates something I can paste directly into the config.xml so I can be sure what I want blocked is blocked anyway. But I'm willing to keep trying on CB until it works.

Check block outbound.
Re-save/update countryblock so the rules are re-applied.
Ping a country that is blocked (check the country txt file if your unsure of any ip ranges)
It should show in the firewall logs and you should get an error that says "operation not permitted" meaning it's working!

@tommyboy180:

The cron script checks to see if countryblock is running. If it is then it will exit and if countryblock is not running then it will attempt to start the package. It's fine.

I've now executed the command manually - and the status page now shows:```
Current Status = NOT running
/tmp/rules.debug:79: cannot load "/usr/local/www/packages/countryblock/lists/countries.txt": No such file or directory
You are blocking 0 Networks
Again, if I start CountryBlock manually via the WebIF its runs until the next PPPOE restart.
But the command /usr/local/etc/rc.d/countryblock.sh does not restart it.
In fact I get this if I execute it manually (yes, it echoes "not running" and then the contents is printed,,,):
$ /usr/local/etc/rc.d/countryblock.sh

I've left the empty lines in.

If I start Country Block via ticking the box on the WebIF and then run the script, it correctly returns```
$ /usr/local/etc/rc.d/countryblock.sh
running
This is all happening on 1.2.3 nanobsd using firefox.

I'm having problems getting embedded running for a test VM. At this time I cannot troubleshoot embedded images. If you can help out and find out where the problem is. Hopefully I will get embedded running soon!

Even gave it a reboot. I'm not getting anything at all on a traceroute to 3 different hosts (I picked ones that are already in my log) so I'm pretty sure its blocking, but nothing in my logs yet.

I just did those options and I found countryblock logs within the firewall logs.
The attached screenshot is from just now.
Edit: if the webGUI says it's running then it's running. There's no way it can be a false positive since it actually checks to make sure the countryblock tables are in pfctl.

Edit2: It only logs attempt coming inbound. If you try to ping out then it's not logged. Sorry for that confusion.

will try but am not entirely clear how. As a first step, I think this message here is key:

Current Status = NOT running
/tmp/rules.debug:79: cannot load "/usr/local/www/packages/countryblock/lists/countries.txt": No such file or directory

I see that after having executed the script from the command window. Pretty much what cron would do. WebIF then still says "not running".

But I don't have the foggiest idea why I can enable Country Block by checking the box on the WebIF - no errors then and works until PPPOE reset or Firewall rules change - restart script does not work, have to restart using WebIF.

Supermule

Exactly what I see now…. and thats why I asked for the cron command. It doesnt work....

It's because he's using embedded. It works just fine on full installs. I need to get an embedded test system going or have someone help me out. In the mean time embedded installs wont be fully supported.

I am running a full install in VmWare…..

The cronjob doesnt start countryblock....

I took a look at your PM and the youtube video. I have determined that you have a typo in your command on the cron job.

Supermule

Thx :)

Still have not figured out the logging thing, but if I bring up pfTop and switch to the rules view I can see quite a few entries that contain "<countryblock>" and "<countryblockw>" (like "drop inet from <countryblock>to #") that have a byte and packet count >0.

So it is working for sure and I can monitor that directly.</countryblock></countryblockw></countryblock>

The actual logging portion that goes the to firewall logs Tab is controlled by pfctl and only incoming traffic is logged. So browsing a blacklisted IP will not create a log entry but someone from that country hitting the pfsense box will generate a log entry. Hope that clears it up some.

Current Status = NOT running
/tmp/rules.debug:18: Rules must be in order: options, normalization, queueing, translation, filtering

Starting to get this now. I have uninstalled, reinstalled, no joy.

I have noticed every time I save/update it adds another line after "set limit table-entries 900000", from that line till your rules a newline is added at each save.

This is also where the error above is occuring.

pfsense 1.2.3, CB 0.2.0, any ideas?

–------------------------

dang, I went into my rules and turned one off then back on... now CB will save and run... somethings up but at least running now.

Installed countryblock on pf 2.0 RC1 from 26 Feb (full install, amd64), it starts but stops instantly. And on the interface-side, i don't have any option to enable/disable any interface. Only lan, which was enabled by default.

Other thing which is more conflicting to understand: at the box to enable you wrote "enable/disable". So any explanation would be right:

enable with box checked
disable with box checked.

Which one is the right? Seems to be new to put that inconsistent "enable/disable" to packages…

See picture to explain the "missing" interfaces:

countryblock.gif_thumb

Supermule

Have you enabled the WAN interface?

dlawley

Just FYI, I had another error like before and it might be worthwhile to get your rules resaved. I just disabled one and re enabled it and was able to go back without any issue with CB.

_igor_

@ supermule: Maybe i was not clear, so see the attached pic. I cannot activate nor deactivate wan, the checkbox is not preset!

It was just an installation and on overlooking the options to set them it was like shown at the pic.
@ dlawley: Which rules to resave? If you mean the country election, these ones i enabled and disabled all, selected only the "top ten", nothing changed the behaviour. Even deinstalled and installed newly, no change. :(

edit:

Looked at the interfaces.txt, which had this entries:

__csrf_magic
em0

deleted that entries and added "any" (only the word). Saved the file and reviewed the interface-section in webgui. Same as before. Only LAN, which is checked, the other 2 interfaces (WAN and GRE) don't have the check-boxes. If i save the setting, the 2 mentioned lines appear again in the interfaces.txt.
But now countryblock starts and seems to work.
Added the cron-entry. Maybe this could be made by the installer?

Thanks for help

Using cron w/ the command /usr/local/etc/rc.d/countryblock.sh with */1 * * * * root, I am unable to get country block to auto-start after it stops (from either a reboot or updating to the latest snapshot). Any tips by chance?

tommyboy180

This is what my cron job looks like. If you still can't get the cron to work, try executing the cron command from console to view any errors that it may be having.

Untitled.png_thumb

That's exactly how mine looks as well :-(. Once it is on, I'm good to go. It's only when I restart the server or hit the auto-update firmware. I can then get it to start again easily using the GUI, I was hoping the cron would solve my woes. I have an update now to do so I will apply that and see if it happens again. As with through out this topic, thank you for being so active :-) I know how hard it is to dedicate the time we have so little of today to help others.

Ah well maybe it is because it reinstalls the apps after the update, that would make sense no? lol, sorry I didn't think about it :-P
