You know it's odd. One one hand, the almost-greybeard in me wants people to stop screwing around with what I take to be standard unix concepts... what are the ephemeral ports, etc. On the other hand, when I take a close look at something like what you just posted, the level of control is hard to argue with - nothing wrong with that. The temptation is still to basically do what you did (thanks BTW) and just revert everything back to what it rightfully should be.... it served us just fine for ages. Or I'll switch to FreeBSD ,unless they're doing the same thing.
