I’ve started having problems where I can’t browse the internet. I quickly discovered I couldn’t ping any sites, but I could ping with IP address, such as Google’s DNS server 184.108.40.206. I figured there was a problem with my PiHole DNS server so I tried a SCP terminal connection, but that wouldn’t start. Then I tried pinging the C2 itself, and that wasn’t responding. After a few minutes I was about to go power cycle the C2, but then the ping started responding, and everything was working correctly again. I’ve no idea what happened. Maybe the C2 crashed and rebooted, maybe a service crashed and restarted, it’s a mystery. This has happened to me twice in the last couple of days.
Is there a log file somewhere that I can examine the time period where things stopped and started working again that might give me a clue as to why the server is non-responsive? I’m running this headless, but I suppose I could plug in something to the HDMI port and see what it looks like when it goes down.
