Snort nginx upstream timeout error
-
For the last couple versions of pfSense I have been having a hard time starting snort. I'm just getting around to deep diving into it and fix the problem.
System: Watchguard 1250e x-core
Storage Type: NanoBSD/CF card (I know i need to change that moving forward soon)
pfSense Version: 2.3-ReleaseWhen I start snort on WAN adapter it takes about 2-3 minutes, then I receive a 504 gateway timeout and here is what's in the System Log.

Jul 5 21:12:13 SnortStartup 78352 Snort START for WAN(35781_sk0)...I have done some vague research and it seems like it might be pointing to a php-pfm directive maybe? or fastcgi parameters, but I really don't know a lot about that. Anyone seen this error or have any ideas what to try? If you need any more information or screenshots of settings let me know.
Thank you.

It says it all above :)
Nano predominantly causes issues due to lack of storage space in /var/ and /tmp… Try to increase the size of those partitions form the Advanced Menu options...

Thank you for the reply BBcan177, I honestly feel honored. I've seen you contribute so much to bug fixes and packages. Nice work by the way. I will look at increasing those values.
I run a 4GB card with 4GB snapshot, do you have any recommendations on values, or the best way to determine what I should set them to? Does it depend on packages or anything else I have installed?

Thanks!

I have increased the /tmp to 120MB and /var to 180MB and rebooted, but still get the 504 gateway timeout error. Nginx error in the system log looks similar.
nginx: 2016/07/05 22:35:52 [error] 43208#0: *1 upstream timed out (60: Operation timed out) while reading response header from upstream, client: 192.168.2.23, server: , request: "POST /snort/snort_interfaces.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php-fpm.socket", host: "192.168.2.1", referrer: "http://192.168.2.1/snort/snort_interfaces.php"

Chamaeleon!
I am facing same issue of "504 gateway time out" during snort reloading of plugin. Have you resolve the problem?
Love me or hate , but do not judge me. :)

Sadly, I've not been able to resolve this yet.

I am having this issue as well. It appeared more or less out of nowhere…
