New 502 Bad Gateway

@gsmornot:

I'm still learning. Can I just enter the two files from reply 165 into the command box via Diagnostics, Command? I am a GUI user.
I have not had any issues yet but following along to prevent any issues. I do use DNSBL and I am on 2.4.1. Was on 2.4 and the related RC's.

Use putty as stated here, and when you log in choose shell and copy paste one row after another. Reboot unit and thats it. And use login "root" not "admin" as stated in video.

Cheers!

MAC user so I used terminal. Thank you for the point in the right direction, patched this morning after waking up to 502 Bad Gateway.

@BBcan177:

As per jimp's suggestion, please try these two patched files which use a pfSense function called try_lock() as opposed to flock().

Run the following commands to download the patched version of the two files from my Github Gist:

fetch -o /usr/local/www/pfblockerng/www/index.php "https://gist.githubusercontent.com/BBcan177/9f9c8e62b166cee07ad16cd4ff59103c/raw"
fetch -o /usr/local/pkg/pfblockerng/pfblockerng.inc "https://gist.githubusercontent.com/BBcan177/7ff15715be0f02afdbe0a00c676aedce/raw"

Recommend a reboot after downloading the patches.

You can review the Gist revisions here:

index.php
    https://gist.github.com/BBcan177/9f9c8e62b166cee07ad16cd4ff59103c/revisions

pfblockerng.inc
    https://gist.github.com/BBcan177/7ff15715be0f02afdbe0a00c676aedce/revisions

Note: The try_lock() function calls might require increasing the timeout setting from the default setting of "5" (seconds)

So Far running for more than 24 hrs without problems on pfsense 2.4.0 - I would say it looks pretty good.

I will upgrade to pfsense 2.4.1 tonight.

I haven't posted here but have been following the thread as I've had similar issues. After so many hours(less than half a day) pfsense gui and shell would become completely unresponsive even though clients still had internet access.

Replacing the files "index.php" and "pfblockerng.inc" with the ones BBcan177 posted seems to have fixed the issue for me. I've been up for 41hrs now without a problem.

Guess I spoke too soon. Just got the 502.  Also this seems to stop the firewall schedules from working as a schedule that was allowing access should have been stopped but access was still available.  Hopefully it's not affecting other aspects of the firewall security.

Is 2.4.1 supposed to fix this without the updated files here?

I saw the redmine ticket was closed due to a new version of pfbng fixing this. Is that automatically installed in 2.4.1? I'm not seeing a package update on my 2.4.1 RELEASE box.

[jimp]

If you ran the 2.4.1 update after the new package was uploaded (2.1.2_1) then it would pick up the new files automatically.

I still have 502 issue when use pfSense 2.4.1 and pfblockerng 2.1.2_1.  :(

Still having the issue after 2.4.1, had to disable DNSBL again.

Hey all,

Try disabling the Dashboard auto-update check. It seems unrelated, but I made this change last weekend and my system has been stable ever since.

I am also experiencing this issue. Error 502 Bad Gateway roughly every 15 hours. Latest version of pfSense and pfBlocker as of the date of this post. I'd post the actual versions but I need to reboot the router to get into the GUI and I can't afford to take down the internet here at this very moment.

As a side note, I've used pfSense for years now and this '502 Bad Gateway' seems to be a reoccurring theme..

Running 2.4.1 and 2.1.2_1 and still getting 502 but also getting a few crash reports to send in each day as well.

Hi,

same here - updates onto last version of pfsene & pfblocker - after about a day it becomes unresponsive.

[beernutmark]

Disabling Snort and it's updates has kept me up and running for 2 days now.  I'm going to wait another day and then re-enable snort and see what happens.  Perhaps Snort needs the same changes that pfblocker has gotten.

I made some additional mods to the code.  Run the following command to download the patched version from my Github Gist:

fetch -o /usr/local/pkg/pfblockerng/pfblockerng.inc "https://gist.githubusercontent.com/BBcan177/7ff15715be0f02afdbe0a00c676aedce/raw"

Recommend a reboot after downloading the patch.

Please let me know your feedback!

Well it finally failed after a week of being stable…

I installed this today and after 6 hours of running my pFsense VM increased disk usage of over 20gb and crashed the VM and needed to be rebuilt.

I don't think the patch would have done that… Confirmed with a few other users. Check your PM for details and we can go from there... Thanks!

Works on my machines since 4 days without a hassle and without filling up the disks.
What was filled up, did you have had a look on the files?

I checked BBcan's pm and started the process again and keeping check on a few things this time. I couldn't check when it happened though as it had reached 109% storage and the VM crashed and when I rebooted it, it took everything with it. Configs for all services where 95% lost (like 3 DHCP mappings remained of a list of 200+, lost all NAT/Rules). So I ended up just factory resetting and am now attempting to replicate the findings. I will keep everyone updated as the day progresses.
