Xen openbsd. FreeBSD and Linux Kernel Cross-Reference. Using OpenBSD's chrooted httpd | vnode.ch. Copyright © 2003-2008 by Marc Balmer. All rights reserved. OpenBSD some time ago changed the mode of operation for the Apache webserver from the normal non-chrooted operation to chrooted operation. This enhances the security of the server on which Apache is run but it imposes a few challenges to the system administrator. In this article I will discuss selected aspects of running a chrooted HTTP daemon and present strategies on how to set up a chrooted environment for more complex applications like database access or using CGI-scripts.
Introduction and Background The OpenBSD HTTP daemon is based on the Apache 1.3 series webserver. Chroot A UNIX filesystems always starts a the root directory, /. The next figure shows the same filesystem hierarchy chrooted to /var/www: The chroot system call only shifts the file system root, it does not isolate the calling process from other system ressources like the process table, memory or sockets. . # chroot /var/www /bin/ksh Chrooting httpd httpd_flags=NO. Flashrd :: Embedded OpenBSD installer. Flashrd creates OpenBSD images tailored for embedded hardware devices and for executing from a virtualized environment. flashrd installs a complete OpenBSD system with "one-touch" upgrade capability. It boots from a ramdisk to make in-place upgrades easy and complete. flashrd partitions default to read-only operation, to minimize flash wear.

Installing OpenBSD 4.4 « Helpful Linux Tidbits. Following the ‘not enough time on my hands’ FreeBSD dive with a Power Mac, I decided to continue on BSD tourbus to OpenBSD. A good friend recommended it to me in the middle of my FreeBSD install and I’d of like to heard about it alot sooner. OpenBSD turned out to be a really great os, particularly for a router/firewall. I now have OpenBSD running successfully and it’s running good. The install does take a bit of work but the results are b-e-a-utiful.
OpenBSD is a shootoff of NetBSD (Berkly Software Distribution) that focuses on security – the code that is in OpenBSD is carefully audited. Dual Boot MacOS? The OpenBSD installer only has support for fdisk and not mac-fdisk so if you plan to dual-boot MacOS you should partition either with mac-fdisk (see the FreeBSD install link above), or with a Mac OS util like Disk Setup.

Manual Pages: ports(7) Instalación de DragonFlyBSD. Ayer comentábamos la disponibilidad del sistema de ficheros HAMMER como estable en DragonFlyBSD. Hoy vamos a ver el proceso de instalación de este sistema, como veremos, resulta de lo más sencillo. Arrancamos la máquina con el DVD de la versión 2.2.1 de DragonFlyBSD y nos encontramos lo siguiente: Pantalla arranque desde DVD El DVD arranca un sistema live con un login (“installer“) que lanza el instalador: Usamos como login installer para acceder al instalador El instalador nos permite varias opciones, incluso configurar un sistema ya instalado.
Escogemos instalar DragonFlyBSD Evidentemente nos avisa que debemos tener copias de seguridad por si hay algo que vaya mal. Nos avisa que debemos hacer backup de los discos si hay algo importante Seguimos escogiendo el disco sobre el que queremos realizar la instalación: Escogemos el disco a usar A continuación particionamos el disco, en nuestro caso vamos a usar una sola partición para el sistema completo sin dejar espacio para otros sistemas.

A project model is a means to reduce the communications overhead in a project.
As shown by [Brooks, 1995], increasing the number of project participants increases the communication in the project exponentionally. FreeBSD has during the past few year increased both its mass of active users and committers, and the communication in the project has risen accordingly. This project model will serve to reduce this overhead by providing an up-to-date description of the project. During the Core elections in 2002, Mark Murray stated "I am opposed to a long rule-book, as that satisfies lawyer-tendencies, and is counter to the technocentricity that the project so badly needs. " [FreeBSD, 2002B]. This project model is not meant to be a tool to justify creating impositions for developers, but as a tool to facilitate coordination.
The FreeBSD project model will be described as of April 1st, 2003. [FreeBSD, 2002A, Section 1.2 and 1.3] give the vision and the architectural guidelines for the project. Introduction to NanoBSD. Copyright © 2006 The FreeBSD Documentation Project Last modified on 2014-02-17 by eadler. Abstract This document provides information about the NanoBSD tools, which can be used to create FreeBSD system images for embedded applications, suitable for use on a Compact Flash card (or other mass storage medium).
NanoBSD is a tool currently developed by Poul-Henning Kamp <phk@FreeBSD.org>. It creates a FreeBSD system image for embedded applications, suitable for use on a Compact Flash card (or other mass storage medium). It can be used to build specialized install images, designed for easy installation and maintenance of systems commonly called “computer appliances”. Computer appliances have their hardware and software bundled in the product, which means all applications are pre-installed. The features of NanoBSD include: FreeBSD, NetBSD, OpenBSD, DragonFly and Mobile Computers (Laptop.

On Laptops. Last modified on 2013-11-13 by hrs. Abstract FreeBSD works fine on most laptops, with a few caveats. Some issues specific to running FreeBSD on laptops, relating to different hardware requirements from desktops, are discussed below. FreeBSD is often thought of as a server operating system, but it works just fine on the desktop, and if you want to use it on your laptop you can enjoy all the usual benefits: systematic layout, easy administration and upgrading, the ports/packages system for adding software, and so on. (Its other benefits, such as stability, network performance, and performance under a heavy load, may not be obvious on a laptop, of course.) However, installing it on laptops often involves problems which are not encountered on desktop machines and are not commonly discussed (laptops, even more than desktops, are fine-tuned for Microsoft® Windows®). This article aims to discuss some of these issues. The problem often is configuring the monitor.

Configuring a FreeBSD IRC Shell Server. BSD Guides :: Doing Stuff With FreeBSD, NetBSD, OpenBSD, & Mac O. General Information This guide details how to set up user accounts with disk allocation. Let’s say you want to limit each user to a specific size disk usage — 100 megs each. You will need to set “user quotas.” Here we go!! Requirements Root Access or Sudo Right Configuration First step is to make sure that quotas are configured into the Kernel. Enable the following line in the kernel config: options QUOTA Next you will need to enable disk quotas in /etc/rc.conf. # echo 'enable_quotas="YES"' >> /etc/rc.conf Note: For finer control over your quota startup, there is an additional configuration variable available.
. # echo 'check_quotas="NO"' >> /etc/rc.conf If you are running FreeBSD prior to 3.2-RELEASE, the configuration is simpler, and consists of only one variable. . # echo 'check_quotas="YES"' >> /etc/rc.conf Finally you will need to edit /etc/fstab to enable disk quotas on a per-file system basis. /dev/da1s2g /home ufs rw,userquota 1 2 /dev/da1s2g /home ufs rw,userquota,groupquota 1 2 # quota -v.

Using WaveLAN IEEE under NetBSD. Wireless networking under NetBSD Wireless networking under NetBSD This document describes how to configure and troubleshoot IEEE 802.11 networking under NetBSD. Comments, additions, and corrections welcome. Configuring the kernel (top) NetBSD supports a number of PCMCIA/Cardbus and PCI based IEEE 802.11 compatible network cards, among them the Lucent WaveLAN, ELSA AirLancer and recent Atheros based cards. To use them, add one of the following to your kernel config: an* at pci? See your platform's sys/arch/*/conf/GENERIC kernel config file for an upto-date list. Using the network (top) Once you've booted a kernel with a 802.11 card driver like wi or ath and it has found your card, try configuring the network by hand.
Most of the network card's parameters can be changed using ifconfig(8) and wiconfig(8) (deprecated), in NetBSD 3.0 (and -current as of August 2004) there will also be a wlanctl(8) command. . # ifconfig wi0 ssid foobar Acting as an access point (top) See also Hoang Q. . #! #!
