Hi,
You can use 'deny known clients', and then list all the MAC addresses you want to ban with a host declaration.

I am running DHCP (also with DDNS) on Fedora Core 2.
I am getting some instances of blank hostnames getting an IP address... I want to prevent those people from renewing their IP.
So I actually have a 2 questions;
1- Can I prevent blank host names from getting a DHCP address? (I know I can deny unknown hosts, but that would require me to enter in all my known hosts manually, somethign I do not want to do, since there is over 250 of them) 2- Since I know their MAC addresses is there a way to deny them a IP from DHCP?
Sure. See the man page for dhcpd.conf, specifically the class and subclass sections and the "hardware ethernet" options. ---------------------------------------------------------------------- - Rick Stevens, Senior Systems Engineer rstevens@xxxxxxxxxxxxxxx - - VitalStream, Inc. http://www.vitalstream.com - - - - They say when you play a Microsoft CD backwards, you'll hear - - Satanic messages, but if you play it forwards, it will install - - Windows...which means Satan is in your system. - ----------------------------------------------------------------------
