It is a big deal if you have a lot of systems -- we had to kill
rwhod years ago. Doing an appropriate grep/sed of our /etc/hosts file
shows WELL OVER 2000 (yes, 2000) IP addresses for Unix systems assigned
to this single geographical site alone (and these are just Unix systems
... if I were to count the PCs attached to the same LAN ...). Even if
you assume that only 3/4s of these are really being actively used,
that's still a lot of workstations. If rwhod were to be run, we
probably wouldn't be able to get any work done.
