Re: [K12OSN] dhcpd failed

What may be happening is that *both* DHCP servers are attempting to respond to the request from this machine, but only one of them (the LTSP -based DHCP server) has all the needed boot information. You have restricted on DHCP server, but how have you restricted the other?

The client is connecting to my ltsp server since I see the mac address
in the message log using tail -f.

I just tried a third system and it works just fine like the first.

I am assuming it is the NIC in th system that fails, even though the NIC
worked fine when the box was a windows system.

Are you sure there's not another DHCP server on the network? And are you sure you want to be assigning public IP addresses to these machines?

I am experiencing limited success with K12LTSP.
I installed K12LTSP Cent OS 5 EL from the ISO download.
In the dhcpd-k12ltsp.conf file I commented the range line and I am
setting up systems by Mac address and fixed IP address.

This system boots with no problems
host finaid70 {
  hardware ethernet 00:B0:D0:C3:0C:A6;
  fixed-address 140.160.216.111;
  filename "/lts/pxe/pxelinux.0";
}

This system begins booting.
Tail -f /var/log/messages states a "dhcpoffer" to the mac address
00:50:70:76:25:EA.
The client eventually displays ERROR! dhcpd failed!
host finaid71 {
  hardware ethernet 00:50:70:76:25:EA;
  fixed-address 140.160.216.228;
  filename "/lts/pxe/pxelinux.0";
}

The failed systems NIC as reported on during the client boot is a
Rhine
II fast Ethernet. But since it is communicating with the ltsp server,
I
assume the NIC is fine.

How can dhcpd fail on one system and work on the other?
