Why FreeBSD Is My Favorite *nix OS

.

Installation

FreeBSD provides a very easy installation process; it uses Sysinstall as an automated installation package to do it for you. All you have to do is answer some questions to create users and tell it which software to install and you are on your way to being up and running in a matter of minutes. The full installation takes longer that a few minutes to complete, but using Sysinstall to set the installation parameters is very quick. This installer takes care of everything needed to have FreeBSD installed and functioning correctly on your system, including user creation, software/application installations, network and peripheral setup, and much more.

Security

FreeBSD is one of the most secure operating systems available. There are a number of security features built into the system that deal with user and file system security. There are also a number of applications compatible with FreeBSD that offer added security beyond the default features. Besides the basic user permissions modified through CHMOD, FreeBSD offers the ability to use ACL and MAC. These options allow user permissions on a more specific level than the basic Unix permissions. You can also use a firewall to secure your system. FreeBSD has two options built in, altq and dummynet, as well as a number of applications available for install like IPFILTER (IPF), IPFIREWALL (IPF), and PacketFilter (PF). Another way to secure your system is change the default password hash from md5 to blowfish in login.conf.

Another great security feature that comes with FreeBSD is the ability to jail a process. This allows for separate environments for processes that are completely locked off from others. These jails function as almost a separate installation of FreeBSD allowing for its own user processes, user accounts, and files. Using a jail helps for testing software and often used by web hosts to give their users control over a virtual server.

Compatibility

There are numerous hardware compatibilities listed on the hardware notice for each release of FreeBSD. It is compatible with all the major processors the most popular being Intel and AMD. There are also thousands of applications available for installation on a FreeBSD system. As well as having all of those application ports available, you can run Linux applications on FreeBSD with the Linux Binary Compatibility system. This allows you “to run about 90% of all Linux applications without modification” (Linux Binary Compatibility).

Ports

The port system is a collection of software that is packaged and ready for installation on a FreeBSD system. You can download the source and install them very quickly and easily. Ports are available from the installation disc, online at the ports collection, or at FreshPorts. Once you have chosen a port to install and have followed the installation procedures, you can stay up to date with the ability to download and compile the updates easily from within the ports system. There are currently over 19,000 ports within 63 categories available for download and use (FreshPorts Stats).

Documentation

FreeBSD has many different options for documentation. They offer eight different kinds of documentation on their website including FAQ, Manual Pages, and the FreeBSD Handbook. There is also a web resources section, a for newbies section, and books and articles. The handbook is in my opinion the the best resource available and can be viewed online in multiple formats and downloaded as a local copy. There are a number of books dedicated to FreeBSD as well; a search on Amazon.com will demonstrate this. You won’t have to browse the web for basic command questions; you can use the man pages on your installation of FreeBSD so you can have general command help locally whenever needed.
