Why not? You've not given any reason at all. Do you know of any malicious behavior that is made possible by leaving the services turned on? The potential exists to use the chargen feature as a part of a DoS attack, but I've not heard of it ever being used as it's not particularly effective unless you have many many machines available, and even then there are much more effective weapons. And what about the rest of the ports? How are they dangerous? I've never heard of an exploit involving any of them. Really I'm just playing devil's advocate here. I don't care if they're turned off or not. I've just never seen any evidence that there's any reason for concern over them. noah -- _______________________________________________________ | Web: http://web.morgul.net/~frodo/ | PGP Public Key: http://web.morgul.net/~frodo/mail.html
