FreeBSD or CentOS? FreeBSD or Linux, that is the question.
Well, the answer is: “It depends on what you need the operating system for and what your hardware requirements are”.
What I like about members of the FreeBSD community, they generally acknowledge that their is no perfect operating system and that Linux has some strong points over FreeBSD, and the other way round. Discussions about differences between FreeBSD and Linux are often level headed and based on facts, though not everything is always measurable (sometimes something just feels….)
A good example is a recent discussion (CentOS vs FreeBSD) on the FreeBSD Forums about whether one should use FreeBSD as server or CentOS, a Linux distribution entirely derived entirely from Red Hat Enterprise Linux (RHEL).
Some of the strong points in favours of FreeBSD mentioned in the discussion are:
Learning UNIX basics
Better on older hardware (low overhead)
Stable and secure
Better memory footprint
Preferred for VPS (RootBSD is a leading hoster FreeBSD VPS’s)
Can run some Linux apps faster than on Linux itself
Better control over software (ports)
Updates and upgrades without ending up reinstalling
Strong points for CentOS:
Experience handy as there are more CentOS related jobs
Security updates are easier
Beefier hardware preferred
Faster install and update times
Slow package patch processes
No compiling from source (FreeBSD has pkg though)
Better hardware support
Note, these features were mentioned in thread, you may have different views. Please don’t start a flame here ;-)
When looking at the FreeBSD vs Oracle Linux benchmarks, keep in mind that both operating systems are quite different kernels, FreeBSD 9 is an RC and that it’s easy to tweak some settings in FreeBSD to make it a lot faster.
FreeBSD or Linus? This question can evoke heated debates, but according to Brandon Wirtz (FreeBSD vs Linux) they’re both great, but if your hardware is supported by FreeBSD, go for the latter. I presume he is talking about servers.
This is an often asked question in newsgroups and forums. The reason for this, is that there is no easy answer. If a straight forward answer could be given, it could have been found on Wikipedia. The fact is, that it is not a yes-or-no-answer question.
Often you will see this ‘political’ answer “It depends”. It depends how you’re planning to use the operating system (desktop, server) and where (home, data center, server room, embedded etc).
Both Linux and FreeBSD have their strong and weak points, but overall, they can do almost anything you ask it to do, but when one wants an answer to the question “FreeBSD or (Debian) Linux?” one needs to find an answer to the following questions first to see which operating system suits one’s needs best:
1) Is your current hardware supported? If the purchase of new hardware is planned, is it supported by either/both?
2) Which operating system is supported by the third party commercial applications vendors that you use? If it is not supported, is there an acceptable equivalent available for the operating system your preference goes out to?
3) Are your current networking hardware (and appliances) supported by the O/S?
4) Are any new third party system management and monitoring tools required? If so, are they supported by the “new” OS?
5) Is your storage hardware and servers supported by your preferred O/S? think of Network Attached Storage, SAN’s RAID, Fibre Channel over Ethernet (FCoE).
5) Is the IT department capable of maintaining (and further developing) the new system, or is there a need to hire new staff? Or, can you get consulting services and/or third party support for your operating system?
There are plenty more questions that can be asked before deciding whether it’s Linux or FreeBSD that fits your needs best.
Have you been in a (work / home) situation where you had to make the choice? It would be nice to find out about your experience. Please share via the comments.
Dru Lavigne has joined the PC-BSD team this month. The first thing she did, was setting up another blog: the PC-BSD Blog. She already posts BSD related posts on it.toolbox.com: A year in the life of a BSD guru.
As for the goal for AboutBSD, I want to turn it into a planet website that aggregates how BSD system admins use BSD. So that new users or system admins can learn that BSD is flexible, powerful, and provides all the freedom one needs to deploy services on BSD.
I would have no hesitation in recommending PC-BSD for desktop use. It has definitely been the best install experience for a desktop system I have had. It seems exactly tailored for someone like me, a developer in an office where we have tried to be operating-system-neutral as much as possible: most of our programmers do run PCs but we have weaned ourselves off any PC-only applications long ago (apart from specialist applications). As I mentioned in the previous blog, it is a smooth and pretty OS, and feels solid.
As announced before, ZFS v15 was successfuly imported into FreeBSD! For a time there was an option of importing just v15 or proceeding directly to v16 but the community has decided to first import the older version for reasons of stability and compatibility with Solaris 10 Update 8. (via)
Millions of home routers at risk.
According to new research delivered today here at the Black Hat security conference, millions of home routers may have a serious security flaw.
In his presentation at Black Hat, security researcher Craig Heffner detailed how an external attacker could gain full control of a user’s router and use that to gain access to the internal local area network (LAN). Though the implications are ominous, Heffner, also detailed a variety of steps users can take to protect themselves.
Foremay has introduced a 1TB 2.5? SATA solid-state drive alongside the industry-leading 2TB 3.5? SATA SSD, as the company expects to see an increased demand in SSD products for the enterprise.

Stopping SSH Brute Force attacks with PF on FreeBSD
Most people know that port 22 is used for SSH communication and due to this common knowledge, you get people using scripts to test for weak passwords. If you look into your /var/log/auth.log and you see tons of fails/errors from users not on your system or from invalid passwords for root, it means you have people trying to break into your system. Truthfully, anyone that puts a system online with port 22 open will see this happen to them. It’s quite common and not direct attack against you, just scripts looking for IPs with port 22 open.
Now it goes without saying that you should make sure you have a strong password that take use of numbers, upper and low case letters and symbols. Doing this will go along way in preventing someone from breaking into your system. You should also ensure that people can’t remotely log in as root by making sure that you have ‘PermitRootLogin’ set to ‘no’ in your /etc/ssh/sshd_config file. This will ensure that no mater how many passwords they try for root they will never be able to log in.
Now you could just set your SSH server to run on a different port or have your firewall redirect a different port from the outside to the system, but what’s the fun in that when you can use a great tool like PF.
Juraj Sipos, the founder of MaheshaBSD, has published an article listing the difference between Linux and BSD:
“This article is not about the history of Unix; however, Unix is such a complex issue that it deserves few words in this respect: BSD family of Unix systems is based upon the source code of real Unix developed in Bell Labs, which was later purchased by the University of California. Thus, the name of the family of Unix systems called BSD is derived from “Berkeley Software Distribution”. The contemporary BSD systems stand on the source code that was released in the beginning of 1990’s (Net/2 Lite and 386/BSD release).
No one person or any entity owns BSD. Enthusiastic developers create it and many of its components are open-sourced.
BSD is behind the philosophy of TCP/IP networking and the Internet thereof; it is a developed Unix system with advanced features. Except for proprietary BSD/OS, the development of which was discontinued, there are currently four BSD systems available: FreeBSD, NetBSD, OpenBSD and Mac OS X, which is derived from FreeBSD. There are also various forks of these, like PC-BSD – a FreeBSD clone, or MirOS, an OpenBSD clone. The intention of such forks is to include various characteristics missing in the above BSD systems, on which these (forks), no matter how well they are designed, only strongly depend. PC-BSD, for example, has more graphical features than FreeBSD, but there are no substantial differences between these two. PC-BSD cannot breathe without FreeBSD; FreeBSD or OpenBSD are independent of one another.”
Every so many months the never ending discussion about the BSD vs GPL license heats up. Supporters for either license have their thoughts and opinions to why one license is better than the other. Some say that these discussions are a waste of time. Whichever license you defend/promote, if you’re interested in reading (and joining in) the discussions, have a look at these two sites:

Linus Torvalds has said Linux wouldn’t have happened if 386BSD had been around when he started up. We trace the history of FreeBSD and how it’s affected the open source world.
The first free Unix-like operating systemavailable on the IBM PC was 386BSD, of which Linus Torvalds said in 1993: “If 386BSD had been available when I started on Linux, Linux would probably never have happened.”
386BSD was a direct descendant of Bill Joy’s Berkeley Software Distribution, which was the core of SunOS and other proprietary Unix distributions. 386BSD and the patchkit for the port to the Intel chip formed the basis for FreeBSD, NetBSD and OpenBSD, which have carried the torch for BSD and open source Unix to this day.
The guys over at RootBSD have updated their blog with a post on the differences between Linux and FreeBSD; partly seen from a hoster’s perspective.
We thought it would be a good idea to help educate our current RootBSD users, and potential users, as to some of the differences between FreeBSD and Linux. We have nothing against Linux at all, we actually like it, however there are very noticeable differences in the two. Without turning this into too much of a religious debate, here are a few points we consider
Let’s start off by looking at, what we believe is, the biggest difference in the two.
First off, Linux itself is a kernel, not an OS! Distributions (Red Hat, Debian, Suse and others) provide the installer and bundle lots of other open source software. There are easily well over 300 different Linux distributions. While this gives you a lot of choices, the existence of so many distributions also makes it difficult to use different distros since they are all a little bit different. Distributions don’t just differ in ease-of install and available programs; they also differ in directory layout, configuration practices, default software bundles, and most importantly the tools and prorcedures for software updates and patches.
FreeBSD is a complete operating system (kernel and userland) with a well-respected heritage grounded in the roots of Unix development. Since both the kernel and the provided utilities are under the control of the same release engineering team, there is less likelihood of library incompatibilities. Security vulnerabilities can also be addressed quickly by the security team. When new utilities or kernel features are added, the user simply needs to read one file, the Release Notes, which is publicly available on the main page of the FreeBSD website.
The post carries on with looking at performance, security and software: FreeBSD and Linux
RootBSD was established with one goal in mind: provide reliable, flexible, and supported BSD-based hosting services to professionals and businesses.
RootBSD gives you the power to innovate and scale on top of the BSD operating systems. Their services are rock solid; in fact, you could call them the BSD hosting solution.
