This last bit of your message, however, brings home how important it is that we all practice "safe connections" (ala "safe sex"). It's chilling to think of a hacker turning on a real machine. It seems to me one can never be too paranoid with any machinery that (1) can cause physical damage or personal injury, (2) allows for the possibility of remote control and (3) connects to the Internet so any scumbag can try his hand at it. I'm not suggesting you personally don't know the drill, Andrew, but a number of messages on this list suggest that some of our users are Unix/Linux neophytes. Please, people, please be sure your systems are "locked down". There are plenty of books and websites providing chapter and verse about good system security practices. Read...understand...implement...maintain. I know I sound like a dotty maiden aunt about this, but from almost the moment my former place of employment went online we saw frequent break-in attempts by people who were obviously trying just because they could---there certainly wasn't any pot of gold lying in wait behind the firewall. If you think our EMC2 work is too arcane for black-hat hackers to bother with, just remember we're posted all over the net (this list, the Wiki, SourceForge, YouTube, CNCZone, etc.) so there are plenty of interesting hints of potential targets for those who are so inclined. One of my grandmother's favorite aphorisms was "An ounce of prevention is worth a pound of cure."
