Look in the directory /etc/cron.hourly and the file /etc/crontab. There is a nightly process which runs find(1) to update the file used by locate(1). There is a nightly logrotate(8). Every time cron(8) does anything as some other user it adds entries to /var/log/auth.log. Even if there is a minus (-) in front of the logfile name in /etc/syslog.conf, that entry will be flushed to disk. The minus only says to wait for the kernel's periodic file system flush (every 30 seconds?) rather than flushing it as soon as it's written. Set your system clock accurately. Keep a pad of paper and an accurate clock next to the machine. Make a note of when the noises occur. See if you can find those exact times in any of the files in /var/log or its sub directories. (this would be a good time to learn about ls -t and grep -B 3 -A 3 12:34 /var/log/syslog | less) Or any time up to a minute before the noise, in case you are hearing the file system flush after the event. Is the system sending mail to itself, perhaps trying to report some trivial configuration problem? Are you receiving mail from cron or is it just piling up somewhere? Are files growing in /var/spool/mail? Cameron -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
