	When configuring a Linux workstation using the simple

	network are predefined. I have tried to use funny
	politically correct name :-)

	Also, each host has an alias which is simply its network
	node number with the "linux-" prefix. For example, the
	machine "orange" with IP number 192.168.1.5 has the
	alias "linux-5".

	The number 192.168.1 is an official number that will never
	be routed on the internet. So it is safe to use it even if you
	get hook to the internet one day. Off course, you local network
	won't be visible from the internet, but at least no internet
	site will clash with one of your local machine.

	idea to use this IP and use "linux-serv" all around your
	net to refer to this server.
