* From the output of the /sbin/route command, you should be able to tell which networks (LANs) your machine is directly connected (the 1st column) and which gateway (the 2nd column) your machine could be used to reach other networks. Consult the "man" page for "route" for more details.
* If there is no "Gateway" for your machine, your machine can only communicate with other machines that are physically connected.
* Any two physically (or directly) connected network machines must know each other's physical network address (i.e. MAC address) before that can start exchanging data. The MAC address exchange process could occur automatically (default) or manually (to be done by the system administrator). To display the list of MAC address known to your machine, type the command "/sbin/arp". Record the output for later use:
raymond@matrix:~> /sbin/arp -n
