Problem/Symptom
Hosts don't appear in
hosts display.
Wrong host address
appears in host table.
11-18
Possible Cause
The Annex hosts command should list
any hosts that broadcast RWHO
packets if the configuration parameter
rwhod Y
is set to .
If the host is sending RWHO packets
correctly, incompatible broadcast
addresses may be causing the
problem.
The Annex assumes that the host
described in the data part of the
RWHO packet sent the packet and that
the source-Internet-address field in the
IP header contains the host's address.
Usually, this assumption is correct
because routers do not forward
broadcast packets. Some RWHO
daemons, however, do forward RWHO
packets.

Action
If you expect to see a host in the hosts
display, and it does not appear, wait
several minutes and then reissue the
hosts
command before assuming
there is a problem. The time between
broadcasts can vary.
Before proceeding, verify that the host
not appearing in the hosts display is
sending RWHO packets correctly by
ruptime
entering
the network or by checking that the
host in question is running rwhod .
Originally, a broadcast packet used a
host address of all zeros (network.0).
Later refinements required a change to
the broadcast address, specifying a
host address of all ones (network.255).
A host configured with a network.255
address will accept network.0
broadcasts. Hosts configured with
network.0 addressing will not see
network.255 broadcasts. You can
configure the Annex for either method
of addressing by setting the
