Do you have the expectation of Nagios guessing your IP schema, and
host names?  There is a way of using nmap, and a script to build a
basis for you.

Services can be applied to hostgroups. For example:

define hostgroup {
	hostgroup_name	myunixhostgroup
}

define host {
	register		0
	name		unix_host
	hostgroups	myunixhostgroup
	[..]
}

define host {
	use		unix_host
	host_name	unix01
	address		172.16.0.2
}

define service {
	service_descript		PING
	check_command		check_ping
	hostgroup_name	myunixhostgroup
}

This reduces the definition of the host down to 3 lines, you're using
a template for all your linux hosts, and the service is applied to the
entire group.  Hope that gives you a head start.
