Este documento describe cómo configurar un servidor DHCP e instalar un servidor PXE en Linux para permitir la instalación remota de sistemas operativos a través de la red. Primero se instala el software DHCP y se editan los archivos de configuración para especificar la interfaz de red y el rango de direcciones IP. Luego se instala el software TFTP, se edita su configuración y se almacenan las imágenes de arranque en el directorio compartido de TFTP. Finalmente, se reinician los servicios DHCP y TFTP y los clientes ahora pueden iniciar
PXE permite arrancar e instalar sistemas operativos a través de la red. Se requiere configurar un servidor CentOS con paquetes como Syslinux, TFTP y vsftpd. Luego, se configura el DHCP, los archivos PXE y se copian archivos de la ISO al servidor TFTP para proveer boot e instalación a clientes por la red. Finalmente, un cliente puede iniciar mediante PXE y instalar el sistema operativo seleccionado a través de la red.

Cobbler - Fast and reliable multi-OS provisioningRUDDER
In a lot of companies, machine deployment is a delicate subject: every administrator has his own recipe, using CD-ROMs, static binary images deployed via the network, peer delegation ...
However, one solution makes the consensus when it comes to automated mass deployments ( except in the Cloud ): PXE boot. The main cons are that the deployment and the management of such a service is a pain, and every OS has its own installation automation system.
This is where Cobbler saves the day: it enables a painless and reliably to create a PXE service, usable on either virtual or physical machines, while beeing the most agnostic possible towards the target OSes and its preconfiguration system (preseed, kickstart, sysprep, ...) while offering the possibility to handle lots of configuration parameters in a modular fashion (network, partitionning, user accounts, configuration management agent...)
This conference aims to introduce the audience to the general concepts of Cobbler, and some scenarios where it would be a useful solution.
This document discusses BOOTP and DHCP protocols. It provides objectives that will be covered, including the types of information required by systems on boot-up and how BOOTP and DHCP operate. BOOTP provides IP addresses and other network configuration details, while DHCP provides static and dynamic address allocation manually or automatically. The document includes figures illustrating operations, packet formats, and state diagrams for both protocols.
Overview of RARP, BOOTP, DHCP and PXE protocols for dynamic IP address assignment.
Dynamic IP address assignment to a host (or interface) is a common problem in TCP/IP based networks.
Manual and static assignment of IP addresses does not scale well and becomes a labor intensive task with a growing number of hosts.
An early approach for dynamic IP address assignment was RARP (Reverse ARP) which ran directly on the Ethernet protocol layer.
The many problems of RARP such as the inability to be routed between subnets were solved with BOOTP (Bootstrap Protocol).
BOOTP, however, ended to have its own set of limitations like lack of a lease time for IP addresses.
DHCP (Dynamic Host Configuration Protocol) was therefore defined as an extension to BOOTP.
DHCP is backward compatible with BOOTP thus allowing some degree of interoperability between the 2 protocols.
The state-of-the-art protocol for dynamic IP address assignment is, however, is DHCP.
DHCPv6 is an adaption of DHCP for IPv6 based networks.
El documento describe cómo instalar y configurar un servidor PXE para instalar sistemas operativos desde un servidor Linux. Se instalan paquetes como DHCP, FTP y TFTP. Se copia una ISO de CentOS a la carpeta compartida y luego al servidor. Se editan archivos de configuración para apuntar al servidor PXE y la ISO. Finalmente, se prueba instalando CentOS en una máquina virtual de manera remota a través de PXE.
