Yep, same here.

You don't need to use -d, but I will just as a comparision:

Ok, so it worked, checked the rules and exited.  Just exactly like it's
supposed to.

I'm guessing your problem is right here:

If your notebook isn't running the DB, Snort can't make the test
connection to it.  It's not actually writing to the DB, it's just making a
connection and waiting on a connection back.  Since you don't have
anything else after that, I'm guessing that's where it's getting hung.

	ps -ef |grep snort
	ps -auxww|grep snort

When you start Snort with -D all output to STDOUT is silently discarded.
Start it without the -D until you get it working.
