Generally this is caused by not having a route defined to the network you
are trying to reach.  If the host you are trying to reach is not on the
same network or subnet, you must define a route with the "route add"
command.  You may need to define a default route where you send all packets
which are not on your local network.  This router will then forward the
packets to the proper destination.  Look in Chapter 7 of the "A/UX Network
System Admin" manual and at the man page for the route command for more
information.
