MAC based DHCP configuration ! Help wanted


helo all,
I'm working on an ISP. Our internal Clients ( in house ) are frequently having some problems of IP conflict. So, i think DHCP would be a proper solution. But at the same time i want to restrict their IP. Can anybody help me? I need some idea abt DHCP server config file which will provide a pre selected IP for a host.
like, if someone have the MAC of 00:C0:26:78:6B:8A
He should obtain the ip 192.168.1.50

Thanx in advance

you wanna use dhcpd. then edit the config accordingly... (i think its /etc/dhcpd.conf but i cant remember for sure off the top of my head)

subnet 192.168.1.0 netmask 255.255.255.0 { - declare network
range dynamic-bootp 192.168.1.x 192.168.1.x; - declare 'pool' of address.

option routers 192.168.1.x; - gateway
option subnet-mask 255.255.255.0; - subnet
default-lease-time 360000; -lease times
max-lease-time 259200;

host yourmachine {
hardware ethernet 00:00:00:00:00; - mac addres of the nic that wants the ip below
fixed-address 192.168.0.x; - ip you want the client to get
}

that should point you in the right direction. obviously you can add as many 'host' methods as you want.

hope that helps.

That's correct! For a list of all dhcpd.conf options, see:
man dhcp-options

There are also some good example configurations listed in:
man dhcpd.conf
