#  FILE   : rwho
#
#  PURPOSE: To test the basic functionality of the rwhod daemon using the
#           `rwho` and `ruptime` commands.
#
#  SETUP: The home directory of root on the machine exported as "RHOST"
#         MUST have a ".rhosts" file with the hostname of the machine
#         where the test is executed. Also, both machines MUST have
#         the rwhod daemon installed. However, it does not need to be
#         active, the test will handle this.
