I have installed it but I am at the same point that I started. However, I found the following information from the script that you attached and it probably is one reason that it does not work. The eth0 in the computer which is the dhcp server is the one which is assigned a static ip address. Here in the script, that ip address is dynamic. The bigger server to which this computer is attached is running static dhcp in which the mac address of the network interface is used. That probably is the one of the reasons why it does not work. #!/bin/sh # # This is automatically generated file.
