I now notice the following notifications at the bottom of the page
= Update = Current
= Remove = Information = Reinstall
Newer version available
Package is configured but not (fully) installed or deprecated.

That's just the key to the list of installed packages.

I assume you are seeing the file existing?

@steveits
once I enter and load the file I receive the following:
<?php
/*

pfblockerng.inc

This tells me I have loaded the pfblockerng
code
I enter the Line Number 4139 and press ENTER
I arrive at the following:
// Create update file indicator for update process
touch("{$pfb['dbdir']}/{$filename}/{$filename}.update");
} else {
pfb_logger('.', 1);
exec("/usr/bin/gunzip -c {$file_dwn}.raw > {$file_dwn}.orig", $output, $retval);

elseif ($file_type == 'application/x-bzip2') {
pfb_logger('.', 1);
exec("/usr/bin/bzip2 -dkc {$file_dwn}.raw > {$file_dwn}.orig", $output, $retval);

				unset($archive_count[0]);

You could always remove and reinstall the package. By default it keeps its settings.

CTRL+F should find "$r = explode(')', $result, 2);" only once. It's several scrolls/pages below the code you posted.

Courierdog

@steveits
Steve, I was just going to say the code you listed is several pages below where I came up at 4139 on my computer.
I use a MacBook Pro
And I stand corrected when I enter the page #4139 I hit enter (return)
I will now go to the file as you described and wait for further instructions.

Courierdog

@nocling
OK
I finally did find the files as you and Steve posted.
They are several pages below where I landed after entering 4139 and pressing enter.

The FROM and TO that has been suggested.
If I do this from the GUI
FROM $r = explode(')', $result, 2);
TO. $r = explode(' ', $result, 2);

Is this a matter of typing over the existing code as displayed and pressing SAVE

Or is there something else I must do.

I have never edited the pfsense code directly only configured the install set up from the GUI

Yes.

If it breaks, edit the file back again, or just uninstall/reinstall the package to get the original file. (you could, say, copy/paste the entire field into a file on your PC)

@steveits
Steve:
Thanks, I entered the code over the existing code, pressed save.
Received the notification the file was saved successfully.

Diagnostics -> Reboot

Login.

For the first few minutes the CPU Usage was 20-40%
Now it is back at 99-100%
I will recheck the code to verify if it was changed.

The current code

if (substr($result, 0, 1) == '@') {

			$r = explode('', $result, 2);

			// pfSense > v2.6 uses an 'ridentifier' string

This is as I was instructed except I expected a space between the ' ',

So any more suggestions?

SteveITS

@courierdog said in More on Abnormally High CPU Usage:

It should be a space:

$r = explode(' ', $result, 2);

Courierdog

@steveits
The edited text code had one space between the two '

%(#000000)[Since it was still running CPU usage of 99-100% I decided to add a second space.]

Result after 15 minutes of operation
CPU Usage = 14-40%

While not back to the 5-26% where was running before I began to get notification of a required License for MaxMind.

SteveITS

@courierdog OK, it had no space above. It needs one, or it won’t process the data correctly. The CPU may fluctuate as it processes. A 2100 doesn’t have a super powerful CPU but does fine for what it is. The dashboard uses CPU as it updates. My 2100 is hovering around 15-25% on the dashboard while watching a streaming show.

Steve: the SG-2100, is a huge improvement over the SG-1100 I started with.
I got the one with the maximum amount of RAM.
My opinion is Netgate should have a slightly more open platform, allow, 3rd party storage and 3rd party RAM.
One other option which I would like to see is a plug in WiFi board.
I like the Netgate pfsense box because it draws so little power, and it is a stand alone firewall.
My other option is a small footprint box suitable for Linux but they draw too much current for the dedicated task.
I have run virtually every commercial home network router on the market.
I have had cyber attacks and a hyjack of my WiFi System.
Since the install of the pfsense firewall, ZERO successful intrusions or hyjacking of my WiFi.
So far I am quite happy with the Netgate SG-2100 pfsense Firewall.
Thanks for your patience and willingness to help a newbie.
While I had worked for a Telco for 22 years, I worked on the RF side of the house.
Any internet networking is all new to me even at 81 I still do all my own work on the Home all Apple Network c/w 2 NAS storage units.

I get your point but especially with the smaller devices I would expect parts are fastened to the board and there aren't slots. Third party parts are tricky, if it causes a problem and the owner wants tech support why should that be on Netgate? Etc.

One other option which I would like to see is a plug in WiFi board.

If you watch this forum a while you'll see people post that FreeBSD wireless drivers are not great. (ref: Netgate support time above) So while theoretically convenient, it's usually better to use an external AP.

stephenw10

Yes with ARM based devices adding additional RAM becomes an issue. And for small appliances it all starts to add to the cost.

You can actually fit a wifi card to the 2100 but the only one I'm aware of that works is the WLE200NX which is a 2x2 802.11n device. So it's hard to recommend that.
There is ongoing work in FreeBSD to bring in far better wifi support but an external AP is always going to be better IMO.

@steveits said in More on Abnormally High CPU Usage:
Steve I was told by the technicians / Engineers at Netgate the WiFi is in fact an LTE Cellular fall back ISP connection not WiFi in the Domestic or Home Type of WiFi.

stephenw10

It's possible to run either, or both. But the m.2 slot for a cellular modem is used by an SSD if you have that so those are mutually exclusive.

ugen0.2: <Sierra Wireless, Incorporated EM7305> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)

But, as I say, the only wifi device I know will work is very limited.

@stephenw10
Steve, it was more wishful thinking of having a built in WiFi port on the Firewall.
It is just more hardware to add the External WiFi Access Point.
I have two distinct WiFi system.
the ISP provided Router also has a built in WiFi which is used as a fall back WiFi as is their ethernet access to the internet.
The entire home network is behind the Netgate pfsense Firewall.

Steve:
I am unsure why but on my SG-2100 to goto the correct place in the code I have to GOTO Line %(#e32400)[4853]

// Collect pfBlockerNG rule names and Tracker IDs
function pfb_filterrules() {
global $pfb;

$rule_list		= array();
$rule_list['id']	= array();
$rule_list['other']	= array();
$rule_list['int']	= array();

exec("{$pfb['pfctl']} -vvsr 2>&1", $results);
if (!empty($results)) {
	foreach ($results as $result) {
		if (substr($result, 0, 1) == '@') {

			$r = explode(')', $result, 2);

			// pfSense > v2.6 uses an 'ridentifier' string
			if (strpos($result, 'ridentifier') != FALSE) {
				$id = trim(strstr(strstr($r[1], 'ridentifier', FALSE), ' ', FALSE));
			} else {
				$id = ltrim(strstr($r[0], '(', FALSE), '(');
			}

stephenw10

Hmm, that's weird. I can't replicate that here on a 2100 running 22.05.

If you download that file from Diag > Command Prompt > Download box and then open it in a text editor do the line numbers actually appear as expected?

Steve:
To ensure I get everything precisely correct.

Please lay out the actual code I need to enter.
I am so new and it is so easy (for me) to make a mess of things.
So far as I have followed your instructions I have not messed anything up (makes me happy)

Please assume I know absolutely nothing (I have ADHD) and when it comes to this sort of thing I have to follow a script.
Thanks

stephenw10

Download the file like this:

Then open that file on your desktop in a text editor and look at line 4139.

Does it appear correct there or do you actually have 'extra' lines in that file somehow?
