Hi All,

Running RHEL4 and wish to setup dhcpd.  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?

Remove any range statements from the subnet declaration(s) in your dhcpd.conf.
