Dale, this doesn't always work. We're running Computone PowerRacks, and
have found that the Online table will NOT work on its own. It needs *help*
from an external event, telnetting into the NAS and issuing the command to
see who is online (whodo). If we do that once every hour or so, the online
table works quite nicely. If we DON'T, then we get frozen users online for
days, and using the "Clear" button results in "unable to clear" or some such.
