hello all. here is what I have. eth0 is pulling a dhcp from my cablemodem. eth1 is set up to my hub. When my second machine also attatched to the hub is given a static IP I can ping through. but I can't get it to pull a dhcp ip from my linux box(Fedroa). here is my conf. I am a newb and this was taken off the internet and tried to change it to my needs.

Someone might be a little more knowlegable about setting up DCHP than myself...but I think it's much easier to use WEBMIN for configuration.

Just use YaST (as it looks like you're using SuSE) and find/install webmin...then open a web browser and enter in https://127.0.0.1:10000 , then login as root...it's a very handy tool

Anyway, this may not help you, but it's still a damn nice tool to have.

That example is much larger than what is required to get you up and running.

This is a much simpler dhcpd.conf that should get you started:

Change your IP range and DNS servers to fit your network, though that is the common IP range for a home network.

ok this works for me I have set it up with a differant ip scheme but isn't the subnet supposed to be 192.168.1.0? just for any one else who may use this.

subnet 20.20.20.0 netmask 255.255.255.0 {
#option routers 172.16.3.25;
option broadcast-address 20.20.20.255;
range 172.16.3.50 172.16.3.250;
}


what's that? You define a net, 20.20.20.0,
and then you set range from 172.16.3.50 to 172.16.3.250...
you should define the range within the net you declared it in!
more like:

subnet 20.20.20.0 netmask 255.255.255.0 {
#option routers 172.16.3.25;
option broadcast-address 20.20.20.255;
range 20.20.20.50 20.20.20.250;
}


and you group up some machines...hope you really want to do that!!!

yeah that was copied of the internet and pasted. I did some tweaking but now much i missed some of it. I am all fixed now.
