Hello all, In the network there is already a W2K server serving as DHCP server for the network. Then we want to implement LTSP, so we need to setup another DHCP server, right? Due to unexpected reason (little by little migration of w98 clients to LTSP), we need to keep the W2K server running in that network. Can we then have 2 DHCP server in the same subnet, only serving pre-determine clients using mac address? Any clue on how to setup the dhcpd.conf?

Hi Fajar,
on the Linux DHCPD I would add an "allow" directive to the pool, and
put your LTSP clients in a class:
subnet 10.0.0.0 netmask 255.255.255.0 {
....
class "ltsp" {
match if ...
}
pool {
...
allow members of "ltsp";
}
}
Afaik W2K DHCP does not have such an option - so you could probably try to fill
the W2K DHCP address range with reservations, so that it does not have any more
IP addresses to serve for other clients that you want. But I did not test that,
so YMMV...
You said you have to have your W2K server running - but couldn't you just
disable the DHCP-Server on it and serve all your clients form the Linux DHCPD?
Recent versions of dhcpd also support dynamic DNS registration, so I don't
see any (technical) reason why to keep the W2K DHCP...
Just my 2c,

Subject: [CentOS] 2 DHCP server in one subnet
Hello all,
In the network there is already a W2K server serving as DHCP server for the
network. Then we want to implement LTSP, so we need to setup another DHCP
server, right?
Due to unexpected reason (little by little migration of w98 clients to LTSP), we
need to keep the W2K server running in that network. Can we then have 2 DHCP
server in the same subnet, only serving pre-determine clients using mac address?
Any clue on how to setup the dhcpd.conf?
Thank you very much.

If you use the 2-NIC configuration on the k12ltsp server you will have a separate switch and subnet for the clients so there is no conflict with an existing DHCP server on your main network - and the k12ltsp server also provides NAT so even windows boxes on the client side will operate normally without other changes.> Due to unexpected reason (little by little migration of w98 clients to LTSP), > we need to keep the W2K server running in that network.

Any clue on how to setup the dhcpd.conf?If you have everything on a flat network it would be best to only run one DHCP server, but either the windows one or the k12ltsp one can be configured to do everything you need. The extra options you need to boot thin clients will simply be ignored by systems that don't want them. The other services on the w2k server can remain even if you shut down its dhcp service and rely on the k12ltsp server for that. -- Les Mikesell lesmikesell at gmail.com

You can define a reservation, add some host (harware mac) to it and specify some custom parameter using named option or directly its number, for 'next-server' and maybe 'filename' (I dont know to much LTSP) Regards OPS: Les sugest to avoid the separate reservation and put all new options in your already existing reservation, why not !> > Due to unexpected reason (little by little migration of w98 clients to LTSP), > we need to keep the W2K server running in that network.
