Linux vs BSD with a little focus on OpenBSD

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.”

BSD Magazine issue 2010-05: Embedded BSD

A new issue of the BSD Magazine is available as free PDF:  Embedded BSD (issue 2010-02)

This is the Table of Contents:

MaheshaBSD: A Live CD Project From The Lake Mansarovar

MaheshaBSD is the name for a Live CD project. Why Mahesha? What does it mean? Mahesha is one of the 1008 names of Lord Shiva – Supreme God of the universe who stands above all gods. This name was chosen because Shiva’s weapon is the same as the FreeBSD’s one – the trident. There is yet another important correlation – supremacy of the BSD code, which (as many IT professionals believe) stands supreme above all operating systems. The connection of Lord Shiva and BSD is therefore logical.

OpenBSD as a Primary Domain Controller

Once a Windows-based network grows beyond around a dozen computers, setting up a Primary Domain Controller to simplify and centralize the management of users, computers and network resources becomes a must. But does the Domain Controller necessarily have to be a Windows machine, thus meaning the end of our project of a completly OpenBSD-based server network?
Of course not! Once again, OpenBSD comes to our rescue and, with the help of a few additional pieces of software, it will turn into a full-blown, secure and reliable Domain Controller.

FreeBSD MySQL Clustering How-to

The PHP, MySQL and Apache stack is a very popular implementation on standalone BSD servers but in demanding high availability [HA] environments the twin spectres of redundancy and fail-over rear their heads. In these scenarios, it is essential to eliminate the single point of failure which is the enemy of 100% uptime.

BSD FILE SHARING – Part 3. FTP

Last time I wrote on SAMBA on different BSD’s. This time I am going to dedicate the article of the series to FTP. Some people do not know that the FTP protocol is the true BSD heritage, as it originated in the 1970′s at Berkeley University, so it is the right thing to dedicate it some space in the BSDMag anyway.

Exploring HAMMER

One of DragonFly’s features is a new file system, called HAMMER. HAMMER has, to quote from the man page, instant crash recovery, large file systems spanning multiple volumes, data integrity checking, fine-grained history retention, mirroring capability, and pseudo file systems HAMMER is available by default on DragonFly BSD.

Embedded OpenBSD

Unix-like operating systems aren’t picky at all. Despite the extreme physical conditions, they can take root on those old computers where most (proprietary) operating systems risk extinction and help them, after years of faithful service, to start new lives as firewalls, routers, proxies …
But sometimes this is not enough: servers must be reliable and old computers are (guess what?) … Old, and this increases their risk of disease. That’s why embedded systems are a great option: they are (relatively) inexpensive, silent, small , reliable … What else could you need? Ok, you have to learn to cohabit with very basic hardware, but the right OS, with the right configuration, will wallow in it!

Making Sense of Data Management on Intelligent Devices

The demand for embedded devices is growing rapidly, and there is a clear need for development of advanced software to deliver new features on limited hardware. Data management is a critical component in these new software systems. Embedded databases are used by portable media players to store information about music and video, GPS vehicle tracking systems to store map data, and monitoring systems to log information. These and other leading-edge industries have learned the importance of managing data reliably with a relational embedded data management system.

BSD in the Industry

After several years of slavery with windows based programs, many programs related with Industry or Engineering are opening the doors to the new trends of UNIX like OS. This is a natural evolution because as the Economy crisis strikes on whole World, the IT infrastructures are also under pressure to decrease at maximum the overall cost.

(Free)BSD quick news and links (week 16)

Welcome to the (Free)BSD leftovers for week 6. In this post we have a mix of news snippets, quick links, howto’s, links ’n software/package updates. Just a round up of those little things I saved up this week. Previous weeks’ roundups can be found here.

FreeBSD News

  1. FreeBSD & Google Summer of Code 2010
    FreeBSD Project is participating in Google’s Summer of Code programme for a sixth year. Undergraduate and graduate students are invited to apply for a grant to spend the summer improving the FreeBSD operating system! More information available on the FreeBSD Summer of code page.
    Students may now apply to participate at http://socghop.appspot.com/. Before applying you may wish to discuss your project ideas on the freebsd-hackers mailing list or on the #freebsd-soc IRC channel on EFNet. Project ideas can be found at: http://www.freebsd.org/projects/summerofcode.html
  2. Have you ever expressed your gratitude to a FreeBSD developer?
    You like FreeBSD and/or operating systems based on it, but have you have ever dropped that developer that maintains/implemented the feature that’s so important to you a note, saying “thank you”?
    Brandon Gooch, a system administrator at Southeastern Oklahoma State University, recently wrote the FreeBSD Foundation to express his gratitude towards FreeBSD developers in general and the recent wireless work in particular.


FreeBSD 9 developments (via):

  1. UFS journalling committed
    Jeff Roberson has committed soft-updates journalling to 9-CURRENT. It enables a small file system journal which works in combination with soft-updates to eliminate boot fsck’s. It is different from most other implementations of file system journalling in that it doesn’t journal raw blocks but sort of meta-data about meta-data
  2. GEOM disk IO scheduler framework
    A GEOM IO scheduler framework has been committed! The framework allows for multiple IO schedulers to be installed on top of GEOM providers (usually disk drives). As a consequence, potentially different schedulers can be installed on different drives. The work was done by Luigi Rizzo and Fabio Checconi.
  3. FreeBSD PowerPC 9.0 snapshot available (for testing)


FreeBSD Ports

  1. Can the current Ports directory and building of it be improved?
    “There has been some discussion lately about if and how to “revamp” the ports system to make it more usable by general users. (…) Unfortunately there has been very little feedback from users themselves – which is probably a mistake, but also – there was very little feedback from the population (not a particularily small one) that is the cross-section of users and developers. Some ideas were presented, but at the end it all started revolving around banding the gaps and smaller improvements that will, I think, be practically invisible to the end-users.”
    Ivan Voras has noted down his ideas in this post: of ports and of men.


Releases

  1. m0n0wall
    m0n0wall 1.32 is out, and it finally fixes the annoying Ethernet link state bug on ALIX boards (and others that use VIA network chips). Some more work has been done on IPv6 support, the DNS forwarder and the hardware monitor.
  2. NanoBSD
    NanoBSD on ALIX in iX 05/2010. This article  ago will appear on page 146 of ix magazine (DE) issue 05/2010


Websites / Social Media

  1. PC-BSD
    As far as i’m aware this page is not officially supported by PC-BSD  / iXsystems, but there is a Facebook PC-BSD page. There’s already quite a popular and active Facebook PC-BSD Group.
  2. iXsystems website
    As of this week iXsystems has a new website. I like the new version as it’s a lot cleaner and makes finding the right server easier. iXsystems is the corporate sponsor behind PC-BSD and FreeNAS.


Guides & Howto’s

  1. Setting up a headless torrent daemon in FreeBSD
    “I have FreeBSD running as a home server for a while now. One of the things I wanted the server to take care of is downloading torrents, so I could shut down my PC whenever I am downloading stuff. With transmission-daemon (net-p2p/transmission-daemon from ports) this is really simple.”  (tweakblogs.net)
  2. Run FreeNAS in Windows for Network Serving and Sharing
    Many of the popular servers are open source and usually are more widely supported for Linux and other Unix-like systems. However, most can be run right inside Windows. This is especially great for temporary solutions or for new or amateur administrators (serverwatch.com)


(Free)BSD Events

  1. Solution Linux 2010
    Last month   “Solutions Linux” took place in Paris, one of the major professional open source events in France. Here are some pictures of the BSD booths : http://www.bebik.net/cgi-bin/album.pl?album=2010SL
  2. A new BSDA Certification session will be held in Nantes, France on 1 June 2010 at BSDay Nantes. Check the BSD Certification calendar for events near you.

BSD / Unix Family News

  1. DragonFly BSD 2.6: towards a free clustering operating system
    This article gives in introduction into the background and history of DragonFlyBSD, its HAMMER filesystem, new features etc
    “The ultimate goal of DragonFly BSD is to allow programs to run across multiple machines as if they are running on one system. The operating system is still far from that goal, but Dillon has done a great deal of rewriting in nearly every subsystem of the kernel to lay the foundations for future work. Much of the rationale behind the design goals is explained on the project’s web site. It’s an interesting read, because it shows how they want to tackle an ambitious vision with a realistic plan…” continues (lwn.net)
  2. DragonFly BSD 2.6.1 with new swapcache released
    DragonFly BSD, the FreeBSD fork, has been updated to version 2.6.1 and incorporates a added a number of new features whilst updating the components of the clustering oriented operating system. A new swapcache has been incorporated which allows the swap space to also retain clean filesystem data and meta-data rather than just memory. (more)
  3. Why OpenBSD’s Release Process Works
    “Twelve years ago OpenBSD developers started engineering a release process that has resulted in quality software being delivered on a consistent 6 month schedule — 25 times in a row, exactly on the date promised, and with no critical bugs. This on-time delivery process is very different from how corporations manage their product releases and much more in tune with how volunteer driven communities are supposed to function. Theo de Raadt explains in this presentation how the OpenBSD release process is managed (video) and why it has been such a success”  (via)

  4. AIX 7.1 is coming
    IBM plans to deliver the next version of the AIX® operating system, AIX 7, and new releases of PowerVM™ and PowerHA SystemMirror for AIX. These new offerings are designed to help companies reduce cost, improve service and lower the risk of deploying and migrating applications to AIX on Power® Systems.The new capabilities planned for AIX 7 are designed to expand the scalability, reliability and manageability of AIX and the applications running on AIX. Key features will provide greater vertical scalability of up to 1024 threads or 256 cores in a single partition, a clustering infrastructure designed to provide highly availability applications with PowerHA SystemMirror and to simplify management of scale-out workloads. Additional AIX 7 will include new management capabilities based on IBM Systems Director that are designed to simplify the management of AIX system configuration. Finally AIX 7 will support the ability to run AIX 5.2 inside of a Workload Partition to allow consolidation of old workloads on new systems (source & more)
  5. IBM Prunes Low-Cost AIX Rev
    IBM has radically improved the bang for the buck on its Power7-based Power Systems 701 and 702 blade servers this week, and is expected to soon deliver similarly priced entry rack and tower servers. And now it has a new, lower-cost AIX 6.1 Express Edition that will match the less expensive hardware and therefore help Big Blue’s AIX platform better compete against Windows, Linux, HP-UX, and Solaris alternatives. The new AIX Express Edition takes the special low-cost pricing that was available only on JS series blade servers and now makes it available across the Power Systems line, including logical partitions on the largest Power 595 (and before too long Power 595) servers.

BSD Magazine (April 2010): Hosting BSD

The BSD Magazine editors have come out with a new issue of this free PDF magazine: Hosting BSD

The Table of Contents is as follows:

Modern FreeBSD Install

All these years sysinstall(8) was helping us to install FreeBSD with most needed options.

X11 without dbus/hald and with three kings

FreeBSD Handbook suggests (check section 5.4.2 Configuring X11), that running sysutils/hal (hald) and devel/dbus daemons is mandatory to have working x11/xorg … nothing further from the truth.

Converting a FreeBSD Port Using PBI Builder

This is an excerpt from the “Becoming a Developer” chapter of the recently released book, The Definitive Guide to PC-BSD.

BSD File Sharing – Part 2. SAMBA

Last time I wrote about NFS on different BSD’s. This time I am going to dedicate this article of the series to SAMBA.

Running VirtualBox OSE with VNC under FreeBSD 8.0

VirtualBox is a type 2 hypervisor that sits directly on top of the host-server OS and is suitable for server, desktop and embedded applications. It will run most OS’s as guest with few exceptions, and like Vmware * there are many pre-built VM’s available.

FreeBSD Firewall with Transparent Proxy Server, DHCP Server and Name Server

If you need Internet-sharing to be available to share allow your network to access the web using only one public IP Address, you need to setup a gateway.

The Squid and the Blowfish

We have grown so much accustomed to Internet access on our work computers, that we can hardly imagine what people ever did all day long on their workplace before!

Hosting Environment Network and Firewall Redundancy with the BSDs

With many large websites and hosting providers relying on BSD operating systems to power their businesses, it only makes sense that many smaller providers take the same path.

Comparison of FreeBSD And OpenBSD: Not One Cake But The Two Ones

The purpose of this article is to highlight some differences between the two BSD operating systems – FreeBSD and OpenBSD.

Introducing Beastie to Strangers

When PC-BSD 8 first came out back in February, I installed the operating system on two of my machines and was very impressed with the new release.

PC-BSD

1. Quick Poll – which pages would you like to see  printed from Dru’s latest book in the upcoming BSD Magazine issue?

2. How does PC-BSD 8.0 compare with Kubuntu 9.10?   This is probably comparing apples with pears, but for those liking comparison reviews, check PC-BSD 8.0 vs. Kubuntu 9.10 Benchmarks

In a majority of the tests, Kubuntu 9.10 performed better than PC-BSD 8.0, but the tests we used in this article are just a subset of what is available to run on both platforms via the Phoronix Test Suite so for those deciding between running PC-BSD / FreeBSD it is important to run the tests relevant to you and also consider the other features at hand for both free software operating systems.

3. PC-BSD’s graphical firewall manager

PC-BSD is a desktop-oriented, FreeBSD-based distribution with KDE as the default desktop environment. The version due to be released shortly is PC-BSD 8. Because it the only BSD-based desktop distribution that’s in a position to compete with the best Linux desktop distributions, I’ll be publishing a number of articles over the next few weeks to introduce those not yet familiar with it to some of its management tools. This post takes a look at the graphical firewall manager.

OpenBSD

OpenSSH 5.4 released

Damien Miller (djm@) posted to announce@ with the announcement of OpenSSH 5.4. Some highlights of this release are the disabling of protocol 1 by default, certificate authentication, a new ‘netcat mode’, many changes on the sftp front (both client and server) and a collection of assorted bugfixes. The new release can already be found on a large number of mirrors and of course on www.openssh.com.

Please read on for the full release announcement

BSD Magazine (2010-03) available: BSD as a desktop (free)

A new issue (free PDF) of BSD Magazine is available now.

Table of contents:

Buil Your Own FreeBSD Update Server

Experienced users or administrators responsible for several machines or environments, know the difficult demands and challenges of maintaining such an infrastructure. The article outlines the steps involved in creating an internal FreeBSD Update Server.

Using OpenBSD and PF as a Virtual Firewall for Windows

The Windows firewall, by default, has many open ports to the local network, like the file and print sharing service ports, which are the source of many security holes. How to protect a Windows host with a basic configuration of an OpenBSD virtual machine with PF as a NAT router and firewall?

Keeping FreeBSD Applications Up-To-Date

An important system administration task, and a principle of running a defensible network, is keeping operating systems and applications up-to-date. In this article you will find multiple ways how to complete this task.

Spam Control with a stock OpenBSD install

Ever since e-mails became ubiquitous unwanted e-mails or spam also known as UCE (Unsolicited Commercial E-mail) or UBE (Unsolicited Bulk E-mail) also became popular. Any chance to control this? OpenBSD has an excellent method to fight spam and this article is about it.

Choosing and Installing a Window Manager with FreeBSD

Step by Step installing with comments and advice. One of the many attractive features of BSD is that the end-user is not tied to a particular desktop or windowing environment.

BSD Live Desktops

Last week Zafer Aydogan, founder of Jibbed, and Stefan Rinkes, founder of GNOBSD, agreed to talk with Jesse Smith about their projects (from which BSD community will surely benefit), themselves and BSD.

BSD goes to the Office: Can BSD compete in a real life consulting workplace?

A reminder on our last issue topic- an article about an experiment to determine a viability of BSD desktop in a real world high pressure consulting engagement. There are many articles that expound on the succes of Linux as desktop, and quite a few accounts of using a Linux desktop in this case or that case. But this one is written not from a perspective of a journalist or home user, but from a system administration and consulting perspective.
