You can try the dmesg command (it
may have some info), check where your system sends info by looking at /etc/syslog.conf. If it sends to /var/adm/syslog, then try looking at syslog again. There will be normal messages such as DNS may put stats into it, messages from Sendmail, that type of thing. Look for things that are not normally there (look at old syslog files to figure out what is normally there versus not).
Anything you think is suspicious but you don't know what it means, try posting it here or check out these two links - you can search for errors in their databases.

Part of it...
System logs may be very useful. However, before you look at them, get the "ls -l", "ls -c" and "ls -u" from the logs- this tells you when the log was last used, etc.- if there's no current information and there should be, those dates are important clues..
You need to know what to look for in the logs. SCO makes it easier by using words like "CONFIG" "NOTICE" and "WARNING" that you can grep for, but on other OS'es you may have to just look manually until you can figure out what sort of key words they would use.
