FreeBSD 8.0: First Look

Up
vote
Down

A look at the newest FreeBSD distribution...
The ZFS file system is included in FreeBSD 8.0 and from previous experience I've found it to work very well. However, my little server didn't really have the resources to properly experiment with it. For systems with enough RAM and disk to justify its use, I highly recommend taking a look at FreeBSD's ZFS implementation - for the snapshots feature, if nothing else. Being able to restore files without reaching for separate backup media can be a wonderful time saver.

How to set up LAMP on FreeBSD...
Setting up a LAMP server is a common task for systems administrators, and FreeBSD is one of the most reliable and stable operating systems available. Why not combine both LAMP and FreeBSD to build a fast and reliable Web server?

In this article I assume FreeBSD is already installed. If not, make sure you download the latest stable production version of FreeBSD and run the installer. I recommend choosing the MINIMUM option at the installer screen to quickly install only the most basic and necessary things.

The FreeBSD jail mechanism is an implementation of operating system-level virtualization that allows administrators to partition a FreeBSD-based computer system into several independent mini-systems called jails. FreeBSD jails offer security, ease of delegation and os level virtualization. This article explains how to upgrade FreeBSD jails using 'make world'. read more...

Comparison Review: FreeBSD vs. NetBSD

A BSD user turns a critical eye to FreeBSD and NetBSD...
NetBSD with gcc 3.3.x doesn't compile as fast as FreeBSD, but NetBSD can compile itself easily for any platform NetBSD supports via build.sh. No such luck with FreeBSD; I had to boot FreeBSD to build FreeBSD. But with NetBSD, you can use the same framework to build under other OS's, even under Cygwin!

Tutorial: How to Build a FreeBSD Firewall with IPFILTER

Up
vote
Down

A step-by-step guide to setting up a bsd-based firewall.
This howto walks you through the process of building one of the most stable and secure firewalls available - a FreeBSD-STABLE firewall with IPFILTER. As a part of the installation process, all services will be disabled except OpenSSH, which will have its access controlled via TCP-Wrappers. The firewall will be configured to log through the syslog facility, but will have its own firewall log files (rather than filling up /var/log/messages). We'll add VESA support into the kernel so that we can use 132x43 screen resolutions, as well as compile support into the kernel for a second ISA Ethernet card if you have one. After we add a warning banner to the system, we'll make BASH the default shell for root, perform a rudimentary setup for root's BASH environment, and redirect root's email to your "normal" account so that the root account on the firewall itself doesn't fill up. Next, we'll download, compile, install, and configure Tripwire, as well as install cvsup so that your ports collection stays up to date. And, lastly, we'll modify the /etc/fstab entries so that some of your partitions are mounted 'nosuid', 'noexec', or 'ro' so that your installation is as secure as possible.

FreeBSD Process Management

Up
vote
Down

This article is a sample chapter from The Implementation of the FreeBSD Operating System
The FreeBSD system supports transparent multiprogramming: the illusion of concurrent execution of multiple processes or programs. It does so by context switching—that is, by switching between the execution context of processes. A mechanism is also provided for scheduling the execution of processes—that is, for deciding which one to execute next. Facilities are provided for ensuring consistent access to data structures that are shared among processes.

Steganography in FreeBSD: Steghide and OutGuess

Up
vote
Down

This article presents an introduction to steganography and the FreeBSD ports of Steghide and OutGuess.
This should get you started on using steganography utilities. The only question you may be asking yourself is "why use such a utility?" Probably the most common use is to safeguard passwords. We all know that we should use different passwords for various tasks. For example, you should use a different password to log into your computer, another to retrieve email, another for online banking, and yet another for when you create an account on a web server. It can be very handy to make a text file of each password and its usage, and to safeguard that file by hiding it in a place no one would suspect to look.

FreeBSD remote install over Linux via SSH

From the not-intended-for-mass-usage dept., the depenguinator will let you turn your Linux box into a FreeBSD box remotely. Imagine the possibilities for insecure Linux systems turning into FreeBSD systems overnight, much to the surprise of the (original) owners...
Many computer systems around the world have been possessed by penguins; some have even been possessed by dead rats. In light of this, it is desireable to exorcize these evil spirits, and replace them with a nice, friendly daemon.

I've put together some code for building a FreeBSD disk image which will boot into memory, configure the network, set a root password, and enable SSH. This can be used to "depenguinate" a Linux box, without requiring any access beyond a network connection.

Desktop FreeBSD: Initial Setup

Up

Down

What to do with FreeBSD after the install...
There are several tasks to which we must attend before actually making use of our freshly installed FreeBSD system. Immediately upon reboot, you will find yourself in the console. While it is possible to setup and use the graphical login managers -- kdm, gdm or others -- it is important to note that this uses extra resources. One of our assumptions is that you might not have all that excess horsepower, so we'll stick with the console login for now.

This general plan should work for other OS's as well.
...I found myself spending the last few weeks installing servers for a small startup. As I did, I remembered the myriad details needed to create servers optimized for both performance and security. While it would easily take a book to explain all the details, this article can certainly cover some of the common pitfalls to watch out for and the logical approach necessary to do the job correctly. I'll demonstrate for a FreeBSD system, but the same logic applies to your operating system of choice.
