This website is a documentation of the results after installing any applications on FreeBSD or Linux.

As a System Administrator I often accept the task to set up a server for the purposes of the office where I work or to make products which are then sold to customers. Almost all of the operating system and applications are applications that use free or opensource. I've made ​​with ispcp omega webhosting running on centos, aya never install isp config running on debian, etc.

In addition to any multimedia purposes I prefer to use opensource and freebsd, when I create a media server (Streaming Radio) uses FreeBSD, Icecast, and ices.

What is FreeBSD?

FreeBSD is an advanced operating system for x86 compatible (including Pentium® and Athlon™), amd64 compatible (including Opteron™, Athlon™64, and EM64T), ARM, IA-64, PowerPC, PC-98 and UltraSPARC® architectures. It is derived from BSD, the version of UNIX® developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.

Cutting edge features FreeBSD

FreeBSD offers advanced networking, performance, security and compatibility features today which are still missing in other operating systems, even some of the best commercial ones.

Powerful Internet solutions

FreeBSD makes an ideal Internet or Intranet server. It provides robust network services under the heaviest loads and uses memory efficiently to maintain good response times for thousands of simultaneous user processes.

Advanced Embedded Platform

FreeBSD brings advanced network operating system features to appliance and embedded platforms, from higher-end Intel-based appliances to Arm, PowerPC, and shortly MIPS hardware platforms. From mail and web appliances to routers, time servers, and wireless access points, vendors around the world rely on FreeBSD's integrated build and cross-build environments and advanced features as the foundation for their embedded products. And the Berkeley open source license lets them decide how many of their local changes they want to contribute back.

Run a huge number of applications

With over 20,000 ported libraries and applications, FreeBSD supports applications for desktop, server, appliance, and embedded environments

Bandwidth Optimization with FreeBSD 7 + Squid + Apache + videocache


Web technology that is increasingly growing not balanced with bandwidth prices down very slowly. It certainly will make us as administrators dizzy 7 circumference on the other side must conserve bandwidth expenditures, on the other hand very often users access the streaming video which is very wasteful of bandwidth.The most difficult of access with limited bandwidth there is video streaming, an increasingly common around us with flash technology
with Flv file format. Besides youtube many other websites, which provides streaming video of them google video, meta cafe.
There's an interesting idea from the people who joined in to mencache video video of frequently accessed. they called the application with the name videocache.

Introduction Sudo

Sudo is a utility that allows system administrators to give users the ability to user or group to run an application, read a file, which can only be run or read by root or another user.
stable version of this utility is sudo 1.6.9p4, released on August 16, 2007. Sudo is free software and distributed under the ISC-style license. Sudo the first time known and implemented by Bob Coggeshall and Cliff Spencer around 1980 at the Department of Computer Science at SUNY / Buffalo. running on the system VAX-11/750 running 4.1BSD. and updated version, credited to Phil Betchel, Cliff Spencer, Gretchen Phillips, John LoVerso and Don Gworek, have been distributed through Usenet newsgroups net.sources in December of 1985. You can read more about the history of sudo in

Squid In the Outgoing Connection Load Balancing

Squid is a proxy and cache content that is often required by our course with a variety of reasons among them to speed up delivery of frequently accessed web client.

Outgoing while load balancing is not optimize the bandwidth available in 2 pieces or more internet connection point and divide evenly cumulative burden on a network.

installation procedure I've ever discussed here His basic idea is that although outgoing load balancing method, is expected to use Squid and traffic that is in use balanced (balance) between connection 1 and connection 2.

if you use the default configuration squid, of course what is expected of you will not be achieved because tcp_outgoing a squid only 1 and can not automatically vary his tcp_outgoing.

Mod_gzip As HTTP Compressor

What is mod_gzip?

mod_gzip is an external extension module that serves to compress the apache http output to speed delivery of text or html to ten-fold when compared with no compression.

Mod_gzip As the name implies, this module uses gzip compression method that is able to reduce shipping volume of a website through http protocol. The advantage of using mod_gzip which I feel is:

1. Minimize the bandwidth of the output from a website, especially a website that has a bandwidth limit per month.
2. Allows speed up access to a website, so people with small bandwidth speeds can access the website comfortably.
