Hi,
Normally dhcp starts by /usr/sbin/dhcpd, which invokes dhcpd on eth0 device.
In your case, the dhcp should start on eth2 (as you mention), you should
then run /usr/sbin/dhcpd eth2 to invoke dhcpd on eth2 device.
You may need to change the file in /etc/rc.d/init.d/dhcpd to make it
invoke the eth2 device.
Hope this solve your problem.

>I just recently installed a default version of K12LTSP-4.0.1 on my machine. I sit everything behind a Linksys Wireless hub that connects to eth0 for which I have it as dhcp client and it receives (192.168.1.102) from the hub in order to access the internet. I also have eth2 which I made static, per K12LTSP instructions to 192.168.0.254/255.255.255.0. This runs a null cable to the uplink port of my hub which in turn connects my lone test terminal client. I am able to access the internet and when running

>My question is how do I allow for my lone terminal client to find my dhpc server from the statically assigned card? I have read and browsed the archives for almost 6 hrs trying to find the answer as well as double and triple checked my cable connections and lights. If anyone can help me I would certainly appreciate it. I know it has to be something small that I am overlooking since my client is probing for an address. I also have attached a copy of my dhcpd.conf file as well. If I need to be more specific pleez let me know.
