      Hmm, hard to say then.
      Hard to imagine some hacker logged into your box (somehow), removed the logs of logging in but not the reboot.

      You have packages installed?

      Watchdog enabled?

        Have 2 packages installed: iperf and pfBlockerNG. I don't believe I have Watchdog enabled.

          Does that box have IPMI or any other out of band access like that?
          That could only really have been caused by some script that ran or something at the console directly since they apparently didn't login.

            Do you have any internet facing services enabled or is the WAN interface completely locked down from the outside? If you do have services open to the broad internet, what are they, and have you checked their access logs?

            Also, can you elaborate on the first line in your logs, what is "root@buildbot3" trying to do?

            Hope this helps.

              That's not doing anything it's first logged output from the kernel. Buildbot3 is our internal buildbox that built the kernel.

                @stephenw10 - thanks for the clarification, just looked a bit suspicious to me at first glance. ☺

                  My machine does not support IPMI. A fuller copy of the log is available here: https://docs.google.com/spreadsheets/d/1JC-8D-RQ44JRlXGF4PXnRid32aUxdZ8RrHdE7Z4GQnk/edit?usp=sharing

                  I had avoided posting the whole thing because I didn't want to cleanse it.

                  The reboot is on row 549.

                  I do have some open ports on the WAN with forwarding rules:
                  Port - Description
                  80, 81 - HTTP
                  2222 - SSH
                  1194, 1196 - OpenVPN
                  8080 - Docker / Rancher
                  32400, 32444 - Plex

                    Is port 2222 just to your firewall?

                      Nothing looks very out of place. Something on your network (192.168.1.4) is trying to open pages on the firewall that don't exist:

                      Nov 15 16:37:48	***REMOVED_ROUTER_HOSTNAME***		nginx: 2018/11/15 16:37:48 [error] 20989#100149: *217580 "/usr/local/www/JNAP/index.php" is not found (2: No such file or directory), client: 192.168.1.4, server: , request: "POST /JNAP/ HTTP/1.1", host: "192.168.1.1"
                      Nov 15 16:37:48	***REMOVED_ROUTER_HOSTNAME***		nginx: 2018/11/15 16:37:48 [error] 20989#100149: *217578 "/usr/local/www/HNAP1/index.php" is not found (2: No such file or directory), client: 192.168.1.4, server: , request: "GET /HNAP1/ HTTP/1.1", host: "192.168.1.1"
                      

                      But that's pretty common, probably just something misconfigured on the client.

                      You could certainly make it more secure by setting ssh to key only and restricting gui access to limited source IPs. If that's not already the case.

                        Port 2222 actually goes to an internal Ubuntu server.

                        192.168.1.4 is a Linksys 4200v2 WiFi router configured as a bridge/access point.

                        I will look into using Key only and restricting the GUI access.

                          Assuming that only you should have SSH access to that server, not the whole Internet, would it not be better to use OpenVPN to pfSense and then SSH to the Ubuntu server?

                            I may have to look into this a bit deeper. My router just rebooted again on it's own today:

                            Nov 28 12:01:59	syslogd		kernel boot file is /boot/kernel/kernel
                            Nov 28 12:01:00	syslogd		exiting on signal 15
                            Nov 28 12:01:00	reboot		rebooted by root
                            Nov 28 12:00:00	php		[pfBlockerNG] No changes to Firewall rules, skipping Filter Reload
                            Nov 28 12:00:00	php		[pfBlockerNG] Starting cron process.
                            Nov 28 11:00:00	php		[pfBlockerNG] No changes to Firewall rules, skipping Filter Reload
                            Nov 28 11:00:00	php		[pfBlockerNG] Starting cron process.
                            

                            Could this be caused by some kind of scheduled job trying to reboot my router periodically?

                              Ok, I just locked down some ports, included SSH (port 2222). Still, this feels like something on the router and causing causing it to reboot. Either a scheduled process, or something causing a fault that results in a reboot.

                                ssh is not port 2222, 22 yes not 2222

                                  They are forwarding port 2222 to ssh here. I assume you locked it down to known source IPs only.

                                  Has it rebooted again since?

                                    Yes, my isp blocks port 22 so I was forwarding port 2222 from wan to port 22 to the internal machine. I turned this off. The router rebooted another 2.5 hours later. I don’t think it has rebooted since.

                                      I just updated to 2.4.4-RELEASE-p1. I will continue to monitor and see if this makes a difference.

                                        @RyanM @stephenw10 Did you ever find a solution to this? I'm experiencing the same exact thing and my logs read the same with random daily reboots.

                                          Exactly the same?

                                          Let's see logs covering the run up to the reboot.

                                            I guess not "exactly" but very similar. For no reason each morning I lose the internet connection to see pfsense is rebooting. I see this in the logs:

                                            And I was not logged into the console and was sitting right next to the box so nobody was physically here.
