To be specific... My Remote Sharing preferences where casually unlocking nearly every day. When I installed Flying Butress. The lock came off once and it has never come off again. To be very speculative and paranoid. That sounds to me like flying butress may have prevented some sort of monitoring system from watching my machine and then perhaps, the "remote admin" came back into machine and changed something again... Since after the firewall installation I found a problem while running a root kit detector. It said the UUCP user on my machine had changed. I don't know how to monitor UUCP. In addition, the flying butress is currently blocking alot of stealth connections. These are harmless correct?
If the remote-sharing box is unchecked chances are your ok
