It smells like you need an authoritative statement for your dhcpd.conf.

This is done by adding the following to the top of your dhcpd.conf:

authoritative;

Hi im trying to configure centos to run as a dhcpd daemon but it simply doesnt work

I'm using the default configuration file from dhcdp (and tried multiple alternatives).

problem is that pxe clients do not aquire dhcp addresses in the log i can see that there are 3 or 4 dhcp offers per boot atempt but no dhcp requests

anyone?

i'm going crazy here... .i've tryed 3 diferent machines (servers) and 4 or 5 diferent clients sometimes windows clients are able to catch the ip but only sometimes.

maybe this is a route problem?

the machine(s) was freshly installed with centos 4.3

please advise!

I don't think the ad-hoc ddns updates will work without the proper keys for rndc included.

---- I think it will but it isn't recommended but whether or not an ad-hoc dns entry is created has little to do with dhcpd assigning an address.

The above dhcpd.conf doesn't make sense to me in that you are assigning 'option subnet mask' as a class B 255.255.0.0 and then defining a class C subnet 10.0.150 with 255.255.255.0

I think these need to be the same type of subnets, thus at the top...

option subnet-mask 255.255.255.0 option broadcast-address 10.0.150.255

Hi I've solved my issues with DHCPD.

As I mentioned, I was trying to configure the DHCP server in a clean isolated install, with only one client with a crossover cable. Network and dhcpd configurations where made as if the server was connected to the network, but as i already had another dhcp server....

As soon as i connected this server on the network (on a diferent segment), everything worked just fine!!!

What can be the causes for this? The lack of dns? The gateway? I've tried to configure the gateway as the local machine itself, but with no results.

Thank you for your kind help!

I'd recommend avoiding RTF/HTML mails to mailing lists, they're generally frowned upon. As is top-posting. Just a friendly prod, I don't mind as-such but I know if irks a lot of people.

Is your problem specific to a particular hardware platform? I've had IBM systems that have caused me all sorts of headaches when Dell kit has been fine and vice versa. Does upping the logging on the TFTPd give you any additional information?

What about the other VTYs when you're netbooting a "client"?
