Do you want to go through the files manually or do you want something to parse them for you? If you go through them manually, you'll need to open them as root (or with su/sudo access) in a text editor. Some info in the logs is self explanatory, some isn't. Are there specific entries you wanted help with?

You could use something like logwatch will will summarise your log files to the level of detail you specify and email you a report (if you run it out of a cron job).

How to read it is with a text editor (you'll need root privileges)

What it means is something we can explain if you show us the lines that don't make sense.

In RH and Fedora you can use Application->System Tools->System Logs

If you dont find it - check your application manager and intall it.

Other systems dont know.

Hope this help.
