can not set the static IP address for ebox machine

[yustao]

When I tried to set the IP address of ebox machine from DHCP address to static IP address, I first changed /etc/network/interfaces to set the address, netmask and gateway. And then, I had to run the command "sudo apt-get --purge remove dhcp3-client". Otherwise, the static IP address setting did NOT work.

But when I ran above command, I found some ebox modules, such as ebox-network, were also removed. But actually, I really do NOT want to remove the ebox modules.  Could anyone help on this?

Thanks in advance,
