SYNOPSIS
dhcpstarv -h
dhcpstarv [-epv] [-d MAC] -i IFNAME
OPTIONS
-d, --dstmac=MAC
Use MAC as destination hardware address for DHCP requests. Default is to use broadcast address.
-e, --exclude=ADDRESS
Ignore replies from server with IP address ADDRESS. This must be valid IP address DHCP server
include in replies as server ID. Usually this is a primary IP address of interface which is
connected to client's network segment.

DESCRIPTION
DHCP starvation is attacking a DHCP server by sending a lot of requests to it. This lead to server's
address pool exhausting after which DHCP server is not able to respond clients and give them new leases.
dhcpstarv is tool that implements DHCP starvation attack. It requests DHCP leases on specified interface,
save them and renew on regular basis.
When a rogue DHCP server appear in network with DHCP infrastructure some clients can get wrong network
settings. Those rogue servers can be switched by users by accident. The only solution to issue is to
disconnect such server from network. But it takes a lot of time to discover rogue server if network is
complicated, i.e. there are many network devices in it. As a temporary solution you can attack rogue DHCP
server until find and disconnect it from network.
