Configuring DHCP Server on Linux (ISC DHCPD)

To use PXE Network Boot, you need a working DHCP server and TFTP server ([Prerequisites for Using PXE Network Boot]).

An example of a DHCP server configuration file with a TFTP server ({color:green}marked green{color}) and a boot filename ({color:red}marked red{color}) is provided below:
{quote}
{color:blue}subnet 192.168.5.0 netmask 255.255.255.0 {{color}
{color:blue}range 192.168.5.200 192.168.5.254;{color}
{color:blue}option domain-name-servers 64.105.113.138;{color}
{color:red}option bootfile-name "pxelinux.0";{color}
{color:blue}option domain-name "yourcompany.com";{color}
{color:blue}default-lease-time 1800;{color}
{color:blue}max-lease-time 7200;{color}
{color:green}next-server "192.168.5.14";{color}

}

{info:title=Note}The next-server (TFTP-server) statement is used to specify the IP address of the server from which the initial boot file (specified in the filename statement) should be loaded. If no next-server parameter is supplied, the client should use the IP address of the DHCP server. But this may not work with some network cards, so it is better to specify next-server explicitly.

{info:title=Note}Trivial File Transfer Protocol (TFTP) is a very simple file transfer protocol. Since it is very simple, its implementations can fit in a very small amount of memory. TFTP was initially used for booting network devices, such as routers, which did not have any data storage on-board. Today, TFTP is still used to transfer small files between different hosts on a network, such as when a remote X Window System terminal or any other thin client boots from a network server. TFTP is also widely used for upgrading firmware on different network devices.
