I have a Ubuntu machine which randomly reboots itself:



last reboot
reboot system boot 2.6.32-042stab12 Sat Mar 25 23:48 - 12:42 (11:53)
reboot system boot 2.6.32-042stab12 Wed Mar 22 18:28 - 12:42 (3+17:14)
reboot system boot 2.6.32-042stab12 Sat Mar 18 05:10 - 12:42 (8+06:32)
reboot system boot 2.6.32-042stab12 Thu Mar 16 13:52 - 12:42 (9+21:49)
reboot system boot 2.6.32-042stab12 Thu Mar 16 09:50 - 13:52 (04:02)


I am trying to figure out why and stop it. I pasted the logs to pastebin here.



I am not doing these reboots. Also, it seems like there is nothing going on (like a crash, etc.) which would cause the server to reboot.






ubuntu reboot

    There's nothing in the logs. Is it a multiuser system and someone else reboots it?

  • did you deploy the unattended-updates service and allow it to reboot after updates if it was required by an update?

Have you checked /proc/sys/kernel/panic? If it's value is 1 then server will immediately reboot on panic. Bad drivers can cause kernel panic.



If it's not panic, check last issue of reboot, maybe overheating is the issue.



last reboot

            Postfix configuration issue with fips on centos 7; mailgun relay

            Image
            Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I am trying to setup postfix to relay all mail generated on the local machine via SMTP to a mailgun relay. I have used the mailgun relay before with success on an ubuntu server, but I am migrating to a Centos 7 server which I will be running in FIPS mode. There error log is below, slightly sanitized. I have a small enough network that I choose to have each machine reach out to mailgun individually (this the loopback-only, 127.0.0.0/8 restrictions) and no firewall open port allowing smtp in to the machine. I assume the FIPS mode (and with it disabling of MD5) is causing problems, but I don't know how to overcome it or if it is even possible for tls_fprint to use some supported hash such as sha256 or sha512. However, the relay=none is slightly concerning since I have relayhost set, but perhaps that is because the smtp process is failing? Any help would be appreciated! postconf -n: alias_database = hash:/etc/alia
