Watchdogd - Hardware Watchdog
-
I updated an SG-2440 to 2.3 a short while ago. I noticed a new option under System > Advanced > Misc referring to a Hardware Watchdog. Just curious if this is supported on the SG2440. If not, do any of the devices on the pfSense store support this?
I ticked the box and hit save, nothing caught on fire but there doesn't appear to be any status to indicate whether the watchdog is actually active/working.
Thanks

That section of the page only shows up when you're running a factory image on a platform where a supported watchdog is detected. So if you see the option, it's available on that hardware.

Oh interesting, ok thanks for the info. And congrats again on the amazing 2.3 release :)
-
And it's disabled by default? Is there a reason not to enable it?

I haven't tried the watchdog personally yet, but we had disabled it by default years ago on ALIX because if the system was too busy, legitimately, with passing IPsec traffic the watchdog might get missed and caused a reset. So while it's useful for many, it may not always make sense to enable it by default for every use case.

I'm running a RCC-VE 2440, same hardware as the SG-2440, right? Why don't I see it on my box?
Thanks,

Same hardware, not the same software.

Did you try out another image on that pfSense box or did you go with the ADI image?
-
To see the Watchdog setting you have to be running the factory image for that hardware, not the CE version. If you bought an SG device, you can login to the portal and download it. If you bought the hardware with CentOS from Netgate and it's now running the pfSense CE image, you won't see that choice.

Is this feature considered stable and recommended to be enabled? I'm on the fence about the SG-2440 vs RCC-VE-2440 but this router is going in a remote location where remote hands don't really exist so stability is extremely important. If the watchdog makes even 1 save it more than paid for itself in the additional cost.
-
I've had it enabled on my SG-4860 at 128 seconds for about 10 days without issue.
That being said, I've never actually experienced a "lock up" of any of my SG units.
-
Is there any way to force a lock up so we can "test" the watchdog somehow?

Something like the FreeBSD equivalent of NotMyFault
