Here's the result of further testing, which leaves me still more puzzled:Running snort 1.8.4 from the command line, omitting the -D option but otherwise using the options cited in my earlier posting, yields alerts. But, typing in all options -- incuding -D -- causes snort to omit writing alerts.
Also, running snort 1.8.4 with -D and (after a bit of time to let snort settle in) sending SIGUSR1 yields the following result:

Something is up, because there's substantial TCP traffic on the network, notwithstading the counter suggesting only 9 TCP packets. Also, the statement that Snort has analyzed "18668 out of 0 packets" doesn't seem quite right.
So, I infer something's not quite right with 1.8.4. At least, not the way I built it <grin>.
