I was told by Quozl that the canonical way to stop the Vanilla server
was to run:
"setgame terminate"
And I recall this working a year ago, but now it doesn't:

zu22 at debian:~/vanilla/lib/tools$ ps axu |grep netrekd
zu22      4249  0.0  0.1   2156   512 pts/0    S    03:07   0:00 ./netrekd
zu22     13205  0.0  0.2   3912   740 pts/0    S+   05:24   0:00 grep netrekd
zu22 at debian:~/vanilla/lib/tools$ ./setgame terminate
Warning: Daemon not running!

So if the canonical method for stopping the server changed could
someone tell me what is the new method?
