[Snort-users] disable /var/log/snort logging

You're right, the -N option turns off packet logging.  Sure it doesn't
write to the disk, but it turns off packet logging within mysql as well
- not cool.  Surely there is a way to have snort log everything to mysql
(even packet logging), without dumping data to the hard drive.  I just
can't figure out how.  I'm starting snort with -b (binary logging)
option, which takes care of it crashing after a few minutes under a
really heavy load.  Even still, logging to the disk is a total waste
because I'll never do anything with the binary logs.

The -N option should suppress logging (while allowing alerts).

Caveats:
	1. I don't know if it will stop logs to mysql, too.
	2. The option doesn't seem to be working on my
		system  (Solaris 8) under Snort 2.0.
