I have it runing ok but what I want to do is set it up so that it doesn't just give away IP addresses freely. What I want to do is only allow the hosts as specified in the host declaration to get IP addresses. Because I only have a couple hosts to look after, I am assigning IP's based on mac's; like so: host shaka { hardware ethernet 00:48:54:8B:C5:38; option host-name "shaka"; fixed-address 192.168.1.4; } Now I have 10 such entries in the dhcpd.conf file. If an unknown laptop/pc plugs into the network I don't want the server to give out an address but right now it does. How do I stop from going so?
