Where can I find a complete list of all the logs in the system?

Where can I find a complete list of all the logs in the system?

I'd like to learn more about forensic analysis, and I'm trying to do the challenges from Project Honeynet. I need to check the logfiles and find the IP's that connected remotely to the computer. I have a dd made image of the harddrive. I think the only service that was running was apache. Besides Apache's logs, what other log files should I check? Where are they located?
