I am using a Nagios plug-in called check_dhcp to monitor both my DHCP
servers. It works by broadcasting a DHCPDISCOVER message and monitoring
any DHCPOFFERs. It reports back a Warning status if not all DHCP
servers respond and a Critical status if no one responds. The problem I
am having is that the Nagios server is running on the same hardware as
one of the DHCP servers and it does not seem to respond to the
DHCPDISCOVER. I can successfully run the plug-in on a separate computer
to get it to respond, but I'd like to test it from the same server
running all the Nagios checks. Is it possible to send a DHCPDISCOVER to
the daemon running on the same computer without using a separate network
card tied to the network?
