I am running an Ubuntu 9.04 server with ISC DHCPd version 3.1.1. I hav many laptops, that I would like to have get the same IP wired or wireless. I have entered the information into a conf file, and with two seperate host declarations everything works fine. However, if I want to add or change a single machine, and I try to do so through Webmin (version 1.470) I get an error that says "You have not permissions to create hosts with duplicate hardware addresses" or "Error: You have not permissions to create hosts with duplicate IP addresses" Is there a way around this?

Thanks for your help
