I am working on it, but without success :(

I have installed webmin and made the corresponding changes that were suggested

[root at localhost ~]# cd /home/olivares/Downloads/
[root at localhost Downloads]# rpm -ivh webmin-1.441-1.noarch.rpm

Webmin install complete. You can now login to https://localhost:10000/
as root with your root password.
[root at localhost Downloads]# cat /etc/dhcpd.conf

        range 10.154.19.1 10.154.19.20;
        }

I changed DHCPDARG=eth0 as was suggested, but not working.

The original machine gets its ip from a central server and then I want to use it as a server for several machines in my classroom.  

It connects to 10.154.19.210 which is its address in the "BIG" network.  it gets DNS 10.154.16.130, 10.128.0.4 and gateway 10.154.19.1

I have been playing with webmin, but either I get [FAILED] messages or it appears to work, but the machines cannot connect to it, or get their own IPs.

Thank you for hanging in there with me.
