Hi I've got a server at our ISP's server farm which rebooted last night. I've contact my ISP and no one there did nothing, also it wasn't a power failure because the reboot is written in '/var/log/syslog':
... ov 26 22:26:16 ns-ilweb1 init: Switching to runlevel: 6 Nov 26 22:26:19 ns-ilweb1 qmail: 1069878379.427182 status: exiting Nov 26 22:26:20 ns-ilweb1 ntpd[32551]: ntpd exiting on signal 15 Nov 26 22:26:22 ns-ilweb1 exiting on signal 15 Nov 26 22:28:09 ns-ilweb1 syslogd 1.4.1#10: restart. ... I've run chkrootkit (last version from unstable) and it didn't find anything. I've gone to the logs and didn't see nothing suspicious. (messages, wtmp, faillog, authlog, kern.log). also, nothing suspicious in '/root/bash_history'. Is there anything else I can do to check why it rebooted suddenly?
