SG-3100 completely offline

wgstarks

After arriving at work this morning I tried to connect to my home network via openvpn and discovered that my sg-3100 was not reachable. Thought at first that there must be some problem with my ISP (Spectrum) so I contacted them. They were able to run ping tests to my cable modem without issue, even reset the modem, but didn't resolve the issue.

After I got home I tried to connect to the webgui on the 3100 without success. Also tried connecting via console. The led's on the ethernet ports were green (none of my LAN devices had an active IP though) and I had a blue pulsing light on the front, but couldn't find a way to connect. Finally used a paper clip to press the reset button (short press). Now I can access the web page, but no idea how to troubleshoot this. System logs start at the time I pressed the reset button. Gateway logs go back further but don't show any events that correspond to the time this issue started. What else should I check?

Do you have the arpwatch package installed?

@johnpoz
I didn’t, but have installed it now.

I’m also seeing this spamming the system log now-

code
Jul 4 07:17:00	ntopng		[AlertsManager.cpp:1158] ERROR: SQL Error: database disk image is malformed select * FROM engaged_alerts WHERE 1=1 AND alert_engine = 0

Possibly caused by the hard reset I had to do on the 3100 to recover. Not sure how to fix this though?

Yeah hard reset can cause corruption.. Prob best to do a clean install..

While I have not actual proof of the arpwatch issue.. I was seeing stability issues where could not access pfsense either via console, ssh or web and it would lock up randomly on package installs. Since I removed arpwatch its back to normal.

In that case I'll probably uninstall it.

I've noticed an issue with temperatures as well. Netgate specs an operating temperature of 0C to 65C. My temps seem to average between 62C and 69C with very little CPU activity.

When I regained access to my 3100 immediately after the hard reset I noticed that the temp displayed was 67C. I haven't found any info regarding what automated actions might be expected with high temps, but was just exploring possibilities. There are no temp warnings in the system log but maybe the are logged somewhere else? This box is installed in my home and normally the ambient temperature will be 85F during the day when no one is home.

Since we don't know the events that lead to your SG-3100 being offline, I'd suggest you re-install pfSense. Simply follow this guide https://www.netgate.com/docs/pfsense/solutions/sg-3100/reinstall-pfsense.html

Let us know if it happens again!

After re-installing can I restore my settings and packages from backup?

ivor

Correct, assuming you made the backup prior to re-installing.

Thanks. Finally got a chance to re-install. Got to say that I don't much like the USB port on this machine. Never had to fight so hard to insert a flash drive. Thought I would break it for sure before it finally went in, and then it didn't want to come back out. Looks like the re-install went smoothly though.

Now I guess it's a waiting game to see if the problem recurs.
