I was under the impression that in 08 there’s a user agent that sits on your Mac that checks to see if the licenses are in use on the network you’re on, on my mac it sits on port 3000 and there’s nothing I can do about it (which sucks for a rails guy).
@skord: use Little Snitch. This allows you to set blocking on any port for anything that attempts to access network resources on your system. It’s great for ahem “borrowed” software.
@maccmann I have it, and for whatever reason, I can’t control that port binding, I haven’t OK’d it, I had to put in a ipfw rule to ban it. I don’t know how it works or how it does what it does.
