I have a 500 SP G4 with 256 Megs of Ram, and I hose my own webpage using Apache on OSX. I also have a cable modem. My computer has always been noisy (it always seems to be working on something), and now that I have OS X, I haven't shut it down in over a month. The other night, I noticed that my computer seemed to be making more noise than usual. All of a sudden, I thought that since I had web sharing on and a cable modem, maybe a hacker or something was connected to my computer. I quickly disconnected my modem, and I haven't heard much noise since. My question is: was my webpage causing the noise, or should I be worried about an unwanted visitor? I can provide more details if I have to, but I don't know what else to say about the situation. Thanks.
