Hi all, I’ve got a cheap Celeron box running OPNSense and it’s been pretty good so far, but I found twice that the device turned off at some point while I was at work, and I have been unable to figure out what’s causing it.
The only change was that I enabled Monit to see if I could figure out what was causing crowdsec to stop sometimes but never ended up configuring anything. I’ve only been running it for a couple months though, so it’s possible that that is not related.
I know that on a Mac (based on freebsd, right?) you can determine whether the shutdown reason was a hard shutdown, regular shutdown, or the power cable being unplugged. Is it possible to do that with OPNSense? I’d like to narrow it down to software or hardware ideally.
If you have a pi or Linux box, try setting it up as a syslog server. Then tell opnsense to use that for forwarding logs to. Doesn’t guarantee you’ll see what went wrong, but maybe it’ll help.
I’m not sure opnsense has journalctl or something similar, but that would be a good place to look for some history, too.
