I setup a dhcp server on a debian.
It is designed to only assign ip addresses to a list of known hosts.
The config file looks like :
The problem is that the log file show thousands of requests from unknown hosts that I was hopping to drop.
Is there any way I can completely ignore the requests from unknown hosts (not even logging them)?
(GNU/Linux)
Ain't it possible to force dhcpd to NOT send any DHCP Offers on a specific interface?
I dont want dhcpd to answer on eth0 but do answer on eth1.

I have two items, only related because they are both regarding dhcpd.
First of all, I keep seeing dhcpd responding to DHCPREQUESTs on eth1 which is my cable modem. For example:
Sep 12 21:00:09 plague dhclient: DHCPREQUEST on eth1 to 204.186.xxx.xxx port 67
Sep 12 21:00:09 plague dhcpd:... (2 Replies)

dhclient.leases - DHCP client lease database
DESCRIPTION
The Internet Systems Consortium DHCP client keeps a persistent database of leases that it has acquired that are still valid. The database
is a free-form ASCII file containing one valid declaration per lease. If more than one declaration appears for a given lease, the last
one in the file is used. The file is written as a log, so this is not an unusual occurrance.
The format of the lease declarations is described in dhclient.conf(5).
