[SLUG] Simple tool to monitor remote scans/probs

I am running Redhat 6.2 and i'm just wondering
if I would already have a simple utility for checking
if anyone has been scanning my ports, trying ports,
trying to telnet in etc.

Do such logs already exist on my computer or do I have
to start a logging service or do I need a third party
application ? 

Thanks !
