I've got a message from my school this morning saying that they removed my machine from the network because they found inappropriate traffics from my machine. At first, I thouhgt my machine (MacBook Pro) has been hacked or something. Later, I realized that I used "Remote Desktop 3" this morning. However, the problem was, I hit the "Scanner" by mistake, and it scanned the machines in the network for few minutes - according to their data, for about a minute. I never used the "scanner" until today because I didn't need to. Anyway, after finding the problem, I emailed them saying that it was the scanner function in the Apple Remote Desktop 3 and there is no way to turn it off as far as I know. And also said I will not use it anymore and I think it is not dangerous function, I believe... After that the guy replied as follow.. "... We do not *know* with any cetainty that you might not turn evil and attempt to connect to other computers on the network, nor that your computer is and always will be secure. We cannot tell if your particular traffic is innocuous or malicous in nature until or unless something happens...." And they will not reactive my network connection until I turn off the scanner function. Isn't it stupid? How to reply to them? Is there any way to turn off the scanner function?
