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.
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 is a tool that automates system installation and management. It reduces installation time by providing a simple web UI and command line to manage kickstart templates and provision a large number of systems. Cobbler was created to simplify Linux installation and allow for frequent reinstallations as required by software development. It uses a DHCP and TFTP server to remotely install systems based on profiles that automate package selection, configuration, and post-installation scripts. Cobbler is well suited for continuous integration testing, development environments, and other scenarios requiring automated provisioning.
This document discusses tools for managing large scale computing environments: Cobbler, Puppet, and Func. Cobbler is a provisioning system that automates OS installation and configuration. Puppet is a configuration management tool that defines system configurations and ensures consistency. Func provides a Python API to manage systems, allowing them to be treated as Python objects. It includes modules to control services, run commands, and integrate with monitoring tools like Nagios. These tools help reduce complexity and enable consistent configuration of large numbers of systems.
This document discusses using Puppet and Cobbler together to provision and manage servers. Some key points:
1) Puppet is used to configure and manage servers, while Cobbler is used for provisioning like PXE booting and installing operating systems.
2) Cobbler can install a base operating system and register the server with Puppet. Then Puppet can configure the server by applying manifests.
3) Koan can be used at kickstart time to register virtual machines as Cobbler systems and provision them, allowing virtual machines to be managed like physical servers.

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.
The document provides an introduction to cloud computing, defining key concepts such as cloud, cloud computing, deployment models, and service models. It explains that cloud computing allows users to access applications and store data over the internet rather than locally on a device. The main deployment models are public, private, community, and hybrid clouds, while the main service models are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS provides fundamental computing resources, PaaS provides development platforms, and SaaS provides software applications to users. The document discusses advantages such as lower costs and universal access, and disadvantages including internet dependence and potential security issues.

PXE Boot Server Using AIO Boot Creater (Pre Boot Execution)IRJET Journal
A PXE boot server allows computers to boot and install operating systems over a network. It simplifies installation, reduces errors, and ensures consistency, especially in large organizations. A PXE boot server requires a DHCP server to assign IP addresses and a TFTP server to transfer files. The client computers are configured to boot from the network. Testing verifies the network connectivity, DHCP/TFTP configurations, and that clients can successfully boot and install operating systems over the network. PXE boot servers are commonly used in large enterprises, data centers, and academic institutions to efficiently deploy standardized software and OS installations across many computers.

This document discusses how data center managers can identify servers that are not performing useful work using Nightwatchman Server Edition software. It notes that rapid server growth has led to underutilized servers, and virtualization exacerbates this through "virtual sprawl". Nightwatchman analyzes server workload at the application level to determine what tasks constitute "useful work" like database processing versus maintenance tasks. It provides graphs showing server power usage and level of useful work, helping identify candidates for decommissioning or putting into low-power "drowsy" mode when idle. The software helps address inefficient energy use from servers performing no productive tasks.
This document describes the challenges of accurately reporting energy usage costs and carbon savings across different geographic locations with variable electricity tariffs. It explains how factors like electricity prices, carbon dioxide emission rates, and utility rebates vary in different places.

Putting users in charge of finding and downloading applications they need through self-service could dramatically reduce help desk costs while adding value. User self-service allows organizations to save $300,000-$450,000 annually by reducing calls to the help desk by 20%. It also improves efficiency and effectiveness by empowering users to fulfill their own needs faster. While maintaining cost reductions, user self-service can increase the business value delivered by IT through faster request handling and more responsive support that is better aligned with business needs. Self-service allows organizations to both cut costs and improve service levels by reducing help desk workload.
BranchCache is a new feature available in Windows Server 2008 R2 and Windows 7 that reduces WAN bandwidth usage. It improves application responsiveness when workstations in a remote location access content from the head office or datacenter. It does this by downloading and caching content on the local network as it is requested, making it immediately available to other clients that subsequently request the same content.
This paper examines the BranchCache functionality specifically in the context of software distribution using System Center Configuration Manager 2007 to determine if it is an optimal solution for the deployment of software, patches and operating systems to remote, serverless branches.

HOW 1E’S PXE LITE PROVIDES THE LOWEST COST NETWORK BOOTING SOLUTION. IT
ELIMINATES THE NEED FOR LOCAL SERVERS AND THE ASSOCIATED COSTS OF MANAGING
THEM.
DAVE FULLER

JANUARY 2011
ABSTRACT: Being able to boot PCs from the network is a must-have requirement for any zero-touch Operating
System deployment solution, especially where new (‘bare-metal’) machines are being delivered, or you need to
rebuild a broken PC that can’t otherwise boot up. We are convinced that the best solution for deploying Microsoft
Windows desktop operating systems is Microsoft System Center Configuration Manager. However, to achieve a
comprehensive zero-touch solution with System Center requires servers to host the Pre-Execution Environment (PXE)
service that enables booting from the network. This paper demonstrates how 1E’s PXELite solution eliminates the
need for these servers and the associated costs of managing them, providing the lowest cost PXE solution for all
distributed IT environments.
