Below is an example from my messages log. I think someone it trying to crack my box but I'm too green to know what he's doing. Are there books or doc files that I can read so that I can understand these files without constantly asking for help? How ever while I learn..... HELP! What is this guy doing? Thanks! I think Mr/Ms "powertech" is trying to crack my Linux box. What do you think? (I'm a newbe and need to find doc files so I can understand this stuff. Please let me know what this guy is up to! Thanks!)
