FreeBSD

O FreeBSD é um sistema operativo livre, do tipo Unix, descendente do BSD desenvolvido pela Universidade de Berkeley. Tal como o Linux, Windows ou MacOS, é multi-utilizador e multi-tarefas, permitindo a execução das mais variadas aplicações. O seu elevado desempenho e estabilidade fez com que tenha sido escolhido por algumas das mais prestigiadas companhias que fornecem serviços na Internet

Road warriors (multiuser configurations) are roaming user clients with dynamically assigned IP addresses unknown to the home IPSec gateway or VPN concentrator. Hence the configuration has to rely on other means of authentication such as deployment of signatures or certificates. This requires a PKI.Deployment of preshared secrets does not scale and often compromises entire architectures that rely o

Do the following steps to enable ext2fs support in the FreeBSD kernel: # cd /usr/src/sys/modules/ext2fs # make # make install You can use ‘kldload‘ to load the ext2fs module in to the kernel. # kldload ext2fs Then you will be able to mount your linux partitions by giving a command like: # mount -t ext2fs /dev/ad1s1 /mnt to unload module use # kldunload ext2fs To load the module

MASTER_SITES controls where the port fetches its source from. By setting MASTER_SITE to the site of a known good source code tarball, you can control where the port downloads from. For example, if you use the command make MASTER_SITE=ftp://ftp2.freebsd.org/pub/FreeBSD/distfiles, then fetch will attempt to pull the distfile directly from that site. If you want to [...]

If you are installing some package using FreeBSD port, it is going to download the package from the internet using fetch.

The Linux kernel is a funny thing. A new kernel should mean increased functionality, but for me and my old-and-getting-older machines, I only seem to lose functionality with upgraded kernels. I hadn't updated Debian Lenny in a while on the $0 Laptop (the Gateway Solo 1450), and when I did it today, I noticed a new kernel being added to the system: 2.6.24-1. I didn't think about the new kernel when I next booted into Lenny, but when I did, I soon discovered that my sound card didn't work anymore. I looked at all the settings, tweaked a bit here and there, but still nothing.

This post describes the configuration of Sendmail to use SMTP-AUTH when connecting to a remote MTA to send messages. Such a configuration would be needed in case you have a dynamic ip and your ISP relays the messages for you, but they require authentication. This is not a post about how to set your mta to authenticate users and to relay for them. This will show you how to set it to authenticate itself to other mta that will relay messages for you. Sendmail comes installed by default on a clean FreeBSD 6.2 system, but is has no support for SMTP authentication using SASL by default, so it needs to be recompiled. Install Cyrus SASL You can compile cyrus-sasl2 lib from ports (if you need to set some special options ) or install it as a package: cd /usr/ports/security/cyrus-sasl2 make install clea Or just install it from packages with: pkg_add -r cyrus-sasl2 Recompile Sendmail First you need to make sure you set the compile flags so that Sendmail uses cyrus-sasl2:   echo " SENDMA

Linux has a large amount of device drivers for hardware not supported on FreeBSD, especially USB devices (see here (http://info.iet.unipi.it/%7Eluigi/FreeBSD/usb-cameras.html) for a related discussion). Not rarely, such drivers have been written based on information derived by protocol sniffing, reverse engineering and the like. This makes the code highly undocumented, and renders the porting effort extremely error prone. To help with this task, I decided to start working on an emulation layer that would let us recompile the linux source code on FreeBSD, and provide a sufficiently complete emulation of the kernel APIs so that device drivers (or at least certain classes) could be used without modifications to their source code

 History of FreeBSDContributed by Jordan Hubbard. The FreeBSD project had its genesis in the early part of 1993, partially as an outgrowth of the "Unofficial 386BSD Patchkit" by the patchkit's last 3 coordinators: Nate Williams, Rod Grimes and myself. Our original goal was to produce an intermediate snapshot of 386BSD in order to fix a number of problems with it that the patchkit mechanism just was not capable of solving. Some of you may remember the early working title for the project being "386BSD 0.5" or "386BSD Interim" in reference to that fact. 386BSD was Bill Jolitz's operating system, which had been up to that point suffering rather severely from almost a year's worth of neglect. As the patchkit swelled ever more uncomfortably with each passing day, we were in unanimous agreement that something had to be done and decided to assist Bill by providing this interim "cleanup" snapshot. Those plans came to a rude halt when Bill Jolitz suddenly decided to withdraw his sanctio

 Who Uses FreeBSD? FreeBSD is used to power some of the biggest sites on the Internet, including: Yahoo! Apache Blue Mountain Arts Pair Networks Sony Japan Netcraft Weathernews Supervalu TELEHOUSE America Sophos Anti-Virus JMA Wired and many more.

  With FreeBSD, you can easily start out small with an inexpensive 386 class PC and upgrade all the way up to a quad-processor Xeon with RAID storage as your enterprise grows. Education: Are you a student of computer science or a related engineering field? There is no better way of learning about operating systems, computer architecture and networking than the hands on, under the hood experience that FreeBSD can provide. A number of freely available CAD, mathematical and graphic design packages also make it highly useful to those whose primary interest in a computer is to get other work done! Research: With source code for the entire system available, FreeBSD is an excellent platform for research in operating systems as well as other branches of computer science. FreeBSD's freely available nature also makes it possible for remote groups to collaborate on ideas or shared development without having to worry about special licensing agreements or limitations on what may be discusse

 What Can FreeBSD Do? FreeBSD has many noteworthy features. Some of these are: Preemptive multitasking with dynamic priority adjustment to ensure smooth and fair sharing of the computer between applications and users, even under the heaviest of loads. Multi-user facilities which allow many people to use a FreeBSD system simultaneously for a variety of things. This means, for example, that system peripherals such as printers and tape drives are properly shared between all users on the system or the network and that individual resource limits can be placed on users or groups of users, protecting critical system resources from over-use. Strong TCP/IP networking with support for industry standards such as SLIP, PPP, NFS, DHCP, and NIS. This means that your FreeBSD machine can interoperate easily with other systems as well as act as an enterprise server, providing vital functions such as NFS (remote file access) and email services or putting your organization on the Internet with W

Como prometía en el post dedicado a la optimización de ADOdb voy a explicar como instalar el sistema de cache APC sobre un servidor FreeBSD 6.x. El APC (Alternative PHP Cache) es un sistema de cache de opcode para PHP, sirve para cachear el código intermedio del PHP y así no tener que interpretar todos los scripts en cada ejecución. Para almacenar este código "compilado" se usa la memoria compartida del sistema. A parte el APC nos ofrece funciones para poder almacenar y recuperar datos de cache. El APC es una extensión PECL que no viene incluida por defecto con el PHP (esto cambiará con la futura versión 6). A continuación describo como instalar y configurar el APC sobre FreeBSD. [1] Instalar el port Suponiendo que tenemos instalado y funcionando un servidor web (Apache+PHP) sólo nos falta añadirle la extensión PECL con: # portinstall pecl-APC Si no trabajas con portupgrade: # cd /usr/ports/www/pecl-APC/ # make install clean Con esto compilamos e instalamos el APC.
