     21 #  FILE   : rwho
     22 #
     23 #  PURPOSE: To test the basic functionality of the rwhod daemon using the
     24 #           `rwho` and `ruptime` commands.
     25 #
     26 #  SETUP: The home directory of root on the machine exported as "RHOST"
     27 #         MUST have a ".rhosts" file with the hostname of the machine
     28 #         where the test is executed. Also, both machines MUST have
     29 #         the rwhod daemon installed. However, it does not need to be
     30 #         active, the test will handle this.
