Deny Decline Messages
Edit '/etc/dhcp/dhcpd.conf' and add or correct the following
global option to prevent the DHCP server from responding the DHCPDECLINE
messages, if possible: 'deny declines;'
Parameter:
Technical Mechanism:
The DHCPDECLINE message can be sent by a DHCP client to indicate
that it does not consider the lease offered by the server to be valid. By
issuing many DHCPDECLINE messages, a malicious client can exhaust the DHCP
server's pool of IP addresses, causing the DHCP server to forget old address
allocations.
