Re: FreeBSD-7 reboots hourly
I had a similar puzzle to unravel with a CentOS (RHEL equivalent) box.
The clues there were in the log files that showed that gdm was exec-ing
shutdown. I'm not suggesting that is the answer here, but looking at
your logs may help.
While the CentOS shutdown process is different than FreeBSD, you might
get some use out of wrapping the commands that shutdown the box to see
who called them. The script below worked for CentOS and probably needs
some modification for FreeBSD, but the idea is to log the caller (and
caller's caller) of all the executables that are used to
shutdown/halt/reboot etc. the system.
(Note that this one errors in ps if there isn't a ppid at one of the
levels, but it doesn't seem to hurt anything and could be cleaned up
with a check of the ppid variables used).
This is a ***CentOS*** script -- use for concept with FreeBSD
$ cat /sbin/shutdown
#!/bin/bash
### Log who is calling a program
###
### Program to be executed
###
true_executable=/sbin/shutdown.orig
#
# Helper commands
#
ps=/bin/ps --noheaders
logger=/usr/bin/logger -t $0[$$]
#
this_ps_line=`${ps} up $$`;
# Get parent
this_ppid=`${ps} -p $$ -o ppid=`;
ppid_ps_line=`${ps} up ${this_ppid}`
# And parent's parent
ppid_ppid=`${ps} -p ${this_ppid} -o ppid=`;
ppid_ppid_ps_line=`${ps} up ${ppid_ppid}`;
${logger} Called by: ${ppid_ps_line}
${logger} w/ parent: ${ppid_ppid_ps_line}
${logger} Remaining parameters: $@
exec ${true_executable} $@

RE: FreeBSD-7 reboots hourly
Hello dear colleagues. 2 days I have strange behaviour on my 7.0-RELEASE-p3 server. It started to reboot once an hour. No any suspicious task in crontab, nothing strange in /var/log. Just silent reboot. I have no physical access to server - only remote one. Question is: what could it be? How to find what send computer to reboot? Just extra information: I had such stuff before - installworld helped me for one week, now it appears again :( Opened services/sockets are: nobody proftpd647 1 tcp4 *:21 *:* root sshd 845 4 tcp4 *:22 *:* postfix smtpd 5115 6 tcp4 *:25 *:* bind named 525 20 udp4 xxx.xxx.xxx.xxx:53*:* nobody nginx 643 4 tcp4 *:80 *:* root couriertcp 769 3 tcp4 *:110 *:* root couriertcp 789 3 tcp4 *:143 *:* root rsync 659 5 tcp4 *:873 *:* root couriertcp 779 3 tcp4 *:993 *:* root couriertcp 760 3 tcp4 *:995 *:* root syslogd461 9 udp4 *:514 *:* also on local interface (lo0) I have apache, postgrey, spamassasin.

RE: FreeBSD-7 reboots hourly
Hm, already did. No any cron tasks - only system ones. Moreover - stopped all non-system services. System is still going to reboot hourly. Try to disable the system jobs also. It could be something like the system tools! Regards, Johan No virus found in this outgoing message.

Re: FreeBSD-7 reboots hourly
There could be memory issues. I had a system which used to periodically reboot. Eventually found out that after some time, when a part of memory is accessed, due to the faulty memory chip, the system crashes and reboots. Try swapping the memory banks and boot the system. If the faulty chip falls in the memory range where the system is booting up, then you will be able to see that the booting fails ! OR Try to replace the memory cards and try to run the system.
