Cluster der kan alt/Install DHCP server

Install DHCP server

Install DHCP server by download and install the DHCP package

sudo apt-get install isc-dhcp-server

Configure dhcpd.conf

Ether the dhcp.conf

sudo nano /etc/dhcp/dhcpd.conf

Uncomment everything and add the following lines at the bottom of the dhcp.conf file. You have to enter the nodes MAC-addresses. This can be added later on, but if you already know the MAC-addresses on the nodes type them in now
