[Nagiosplug-devel] check_dhcp / rogue dhcp server detection

[Matthew Wilson]

Has anyone given any thought to adding a flag to check_dhcp, so that 
when IPs are returned, the specified servers are the ONLY servers that 
can respond.  Currently, check_dhcp makes sure that each server in the 
list responds, but what if there's an additional dhcp server that 
responds?  This might be an effective way to actively monitor for rogue 
dhcp servers on your network.

I was considering having a stab at it myself, but I'd rather not if 
someone's already implemented it (not to mention my C skills are rather 
lacking).

Thanks!
Matthew
