Pfsense 2.1-release - Gateway aPinger broken?

pfSensible

I ran into this problem for the first time. I have WAN failover configured but not load balancing. I rebooted one WAN modem and now the GW monitor just died and will not come back.

It is configured to ping every 2 seconds

Hi Guys,
I am experiencing exactly the same issue, got 2 WANs configured for loadbalancing, but since the update I noticed that loadbalancing is not working anymore besides the fact that the 2nd WAN in marked as offline.
I have also a tier 2 H3g connection set up on the loadbalancing, I noticed that pfsense is keeping it up even though both WANs are up and running….
My broadband connections are both Pppoe.

I'am planning to roolback to 2.0.3

Bye

What version you are using? Does anyone tried 2.1.3 version?

I upgraded from 2.0.1 to 2.1.2, I also tried 2.1.3 but the issue is still there…

I am on 2.1.3 and I can confirm huge issue with apinger. My otherwise stable WANs are shown as "Pending" no matter what monitor IP I set. Even setting the gateway IP address one hop away causes the apinger to show the WAN as Pending and therefore exclude it from the gateway group, causing interruptions all the time.

BTW, all of you who are experiencing this issue, is it the case that this is due to having traffic shaper configured? Or does it happen even without traffic shaper?

This is a very core, basic function and must be fixed asap.

Can anyone specify if apinger has been fixed yet… or if there is a good work around? I've got two WANs, both static, and since upgrading to 2.1p1 it's needed the apinger service reset frequently. I've got multiple other devices at other locations, DHCP and Static that have had to reset the apinger since the 2.1 upgrades started.

Thanks for any help.

Hi Bob,

Please try the work around we used and got good result:

There's definitely still a problem in 2.1.4 and since 2.1.5 just released and I know that they are still trying to figure out the problem, I'm assuming it is still an issue in 2.1.5.

I have this problem on ONE pfSense box with a flakey T1 (yes, they DO exist, but apparently only in Detroit). I have never seen this on any other of my many pfSense installations.

They are aware of the issue and trying to figure it out. I'm in communication with them and have given them access to the ONE firewall where I have this problem.

In the meantime, I'm going to create a CRON job to restart apinger service at given intervals. BTW, this command will restart it:

/usr/local/sbin/pfSsh.php playback svc restart apinger

Yes, it's still there, hope it will disappear in 2.2.

Please report it and discuss in the following 2.2 thread:

I already did.

Supermule

I have this Cron job running every 5 minutes and for now it has been running no isssues.

pkill /usr/local/sbin/apinger -c /var/etc/apinger.conf

It seems some sort of buffer is filled on WAN DHCP interfaces and it begins to "suffer".

I havent got any issues on static WAN interfaces.

Derelict

I just had to disable gateway monitoring on a pfSense in a datacenter because apinger started seeing 6% loss no matter what was going on. Steady - every sample. 2.1.5 i386.

@krylou:

I`ve found temporary solution - restarting apinger every 5 minutes.

Open shell via putty

Go to /usr/local/www
and create file apinger.php with the following content:
require_once("/etc/inc/service-utils.inc");
require_once("/etc/inc/globals.inc");
require_once("/etc/inc/vslb.inc");
require_once("/etc/inc/gwlb.inc");

service_control_restart(apinger,restartservice)
?>

chmod 755 apinger.php

To run it manually you can just open http://pfsense/apinger.php

Then install cron package via pfsense UI and add new job:
*/5 * * * * /usr/local/bin/php /usr/local/www/apinger.php

Little extended script:


require_once("/etc/inc/service-utils.inc");
require_once("/etc/inc/globals.inc");
require_once("/etc/inc/gwlb.inc");

$counter = 0;
$a_gateways = return_gateways_array();
$gateways_status = array();
$gateways_status = return_gateways_status(true);

foreach ($a_gateways as $gname => $gateway) {
	if ($gateways_status[$gname]) {
		$str_data = $gateways_status[$gname]['delay'];
		$pos = substr($str_data,0,strpos($str_data, "ms"));
		if (floatval($pos) > 500 ) {
			$counter++;
			#print_r($counter ." - ". $pos ."\r\n");
		}	
	}	
}
if ($counter > 0) {
	service_control_restart(apinger,restartservice);
}
?>

What does this do ?

btw. This:

Both kill my RD Graphs. Is that just me ?

**Just disable NTPd time sync daemon.

apinger wil become stable.**

That might help if you're running pfSense in a VM, but the problems with apinger are nowhere near that simple to solve.

apinger has been replaced by dpinger in pfSense 2.3. Though 2.3 is still in beta, the core functionality is now very stable and it has a lot of worthwhile enhancements and fixes over 2.2.x.

Packages are still a mixed bag on 2.3 - some have been converted, some are available but haven't had a proper GUI conversion and others are not available at this point.

If you want to try 2.3, I strongly recommend backing up your configuration and making sure you have working 2.2.6 install media to hand before upgrading. That way, you can revert easily to 2.2.6 if necessary.
