I don't use check_dhcp myself but according to this post it's a limitation of dhcpd. It seems like a good thing to me for the DHCP server not to give itself a lease ;) I can't narrow my search enough with google to find relevant information but perhaps you'll have better luck. http://article.gmane.org/gmane.network.nagios.user/33977/match=dhcp+mach ine -- Marc Using Tomcat but need to do more?
