DHCP and MAC addresses
Hello List, Suppose I have 100 Desktops, and I want my DHCP server to _only_ assign IP addresses to these hosts, using MAC addresses, is there a way to tell the DHCP server to NOT assign any IP address to a machine whose MAC address it doesn't know? I don't want any computer being plugged onto my LAN and getting/using resources without my knowledge. Just some level of paranoia:-) -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Life must be understood backwards; but... it must be lived forward. - Soren Kierkegaard Oh My God!

It wasn't a mistake. As a matter of fact, you can decide to reply to the poster or to the list. I appreciate your response anyway. What I was asking, out of curiosity, is whether there is an alternative to isc-dhcpd-server on FreeBSD. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Life must be understood backwards; but... it must be lived forward. - Soren Kierkegaard Oh My God!

Interesting how many people dual-live on this list:-) I have been so allergic to Linux all these years until Ubuntu. I am from Africa and I did not settle on Ubuntu just for the name but because one client insisted he wanted a Unix server and it had to be Linux. I wonder what makes people live in both worlds - *BSD Linux - is it for similar reasons? As regards DNS and DHCP servers, I'd never thought beyond BIND djbdns and isc-dhcpd respectively all these years (yes, my own Unix epoch is 1997). -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Life must be understood backwards; but... it must be lived forward. - Soren Kierkegaard Oh My God!

Living in both worlds is a good thing: keeping an open mind about operating systems and software is one of the best choices one can make. BSD falls short in some areas where Linux excels, and Linux falls short in some areas where BSD excels. It's about using whatever tool works to get things done. If that's BSD, great. If that's Linux, great. If that's Windows, great. But the worst thing one can do is remain close-minded about operating systems; one-sided advocacy (pro-BSD or pro-Linux) does nothing but hurt the open-source concept.

Re: DHCP and MAC addresses
Hello List,
Suppose I have 100 Desktops, and I want my DHCP server to _only_
assign IP addresses to these hosts, using MAC addresses, is there a
way to tell the DHCP server to NOT assign any IP address to a machine
whose MAC address it doesn't know?
of course.
and you can assign IP to each MAC
first
deny unknown-clients;
(dont specify range at all)
then
host something {
hardware ethernet 00:11:22:33:44:55;
fixed-address 1.2.3.4;
option host-name something.somewhere;
option routers router_IP;
}

But do define the subnet:
subnet 192.168.1.0 netmask 255.255.255.0 {
option routers 192.168.1.1;
option domain-name-servers 1.2.3.4;
}
If you have 100 MAC address by this technique you avoid writing
options routers 1.2.3.4; in each host declaration.
No matter how many subnets you have, just define them and write the
router and DNS server(s) there and in the host declaration just the IP and
(optional)
a host-name.
all the best,
v
then
host something {
hardware ethernet 00:11:22:33:44:55;
fixed-address 1.2.3.4;
option host-name something.somewhere;
option routers router_IP;
