Configure DHCPv4 server

The steps to configure DHCPv4 server are as follows:

1. Install DHCPv4 server: sudo apt-get install isc-dhcp-server.

2. Edit /etc/dhcp/dhcpd.conf file as shown below.

   default-lease-time 600;
   max-lease-time 7200;
   ddns-update-style none;
   log-facility local7;
   #option definitions common to all supported networks…
   option domain-name “cloudboot.com”;
   option domain-name-servers 192.168.10.20;
   option routers 192.168.10.1;
   option vendor-class-identifier “HTTPClient”;
   option bootfile-name “http://www.cloudboot.com:8080/EFI/Shell.efi”;
   #This declaration allows BOOTP clients to get dynamic address.
   subnet 192.168.10.0 netmask 255.255.255.0 {
        range 192.168.10.100 192.168.10.250;
        option subnet-mask 255.255.255.0;
        option broadcast-address 192.168.10.255;
   }
   

3. Be sure that your server will listen for DHCP requests on the correct interface (Note: change the INTERFACE to match your own). Edit the /etc/default/isc-dhcp-server file:

   INTERFACE = “eth0”;
   

4. Restart the DHCPv4 service: sudo service isc-dhcp-server restart.
