PC-BSD 1.3.4 Review

FreeBSD along with OpenBSD and NetBSD form the triumvirate of BSD operating systems. Traditionally these BSDs are server centric operating systems - ie. those which are tuned to be run on a server rather than to be used by the end user as a desktop. Still, with a bit of tweaking and configuration, all the three of them can be used as viable desktop operating systems.

PC-BSD is a direct descendant of FreeBSD. As the name indicates, PC-BSD is a BSD operating system which lays stress on its use as a Desktop catering to the end users. From the point of its inception, the USP (Unique Selling Point) of PC-BSD has been to make it as easy as possible to install, update and use software, at the same time bringing all the powerful security features and stability of the traditional BSDs. Over one year back, I had reviewed PC-BSD 1.00 and if you have read the review, you would have found that my initial impression of this operating system was very positive. In the succeeding months many changes have taken place for PC-BSD. For one, in October 2006 PC-BSD got acquired by iXsystems which is now in control of the project - though Kris Moore, the founder of PC-BSD is still its project leader and has the final say. Apart from the acquisition, the project has moved quite smoothly.

One of the main changes I can see for PC-BSD 1.3 when compared to ver 1.0 is the drastic enhancement of the graphical installer with a couple of additional options thrown in. For example, at the time of installation, there is an option to encrypt the swap partition, there are options to open or close most popular ports such as the port used by SSH and so on, a choice of enabling or disabling the firewall and with a few clicks you finish installing the OS.

The current version of PC-BSD is ver 1.3.4. Some time back, I had downloaded ver 1.3.0 of PC-BSD and had installed it on my machine. The PC-BSD team have made it possible to upgrade the OS to the most recent version - 1.3.4 by downloading and installing a couple of patch files. Thus I had to download and install just over 40 MB of patch files which are made available in PBI format, to upgrade PC-BSD from ver 1.3.0 to 1.3.4. As a matter of fact, you do not even have to download individual files yourself to upgrade the OS. There is a GUI tool called "PC-BSD Online Update" which can be accessed by navigating through KDE Menu -> Settings -> System Administration -> "PC-BSD Online Update", that can be configured to automatically detect if there are updates available and then download and install them for you.

Post Installation scenario

It is really remarkable that the installation of PC-BSD went without any glitch and all the peripherals were detected properly. Sound worked out of the box and in no time, I was face to face with the graphical login screen. PC-BSD is a KDE centric operating system and comes with the latest version of KDE ver 3.5.5 and many useful software installed by default.

Once I logged into PC-BSD, I navigated to the PBI resource web page which contain the latest versions of most popular software such as FireFox 2.0.0.3, OpenOffice.org and so on and started installing those software which I use on a regular basis. As far as PC-BSD is concerned, you do not have to worry about dependencies as each PBI is a stand alone package which contain all the necessary libraries needed to run the program. So FireFox PBI will contain not just the FireFox binary but also dependent libraries as well.

The PBI (short for PC-BSD Installer) is a GUI installer that is similar to its Windows counterpart, and is coded using Qt. To install a software, just double click on the respective PBI and follow the instructions. You also have the option of cleanly uninstalling the software from within the PC-BSD software manager.

Essential housekeeping in PC-BSD

One of the first things you should do the first time you boot into PC-BSD is to update the ports and install them. PC-BSD uses the FreeBSD 6.1 ports. And when you install software using the ports, you are essentially installing FreeBSD software. But unlike FreeBSD where you have to dabble with command line to update and install the ports, in PC-BSD, you can do the same using the GUI front-end with the click of a button (See the image below).

Next I had to install the multimedia codecs to enable PC-BSD to play audio and video files in proprietary media formats. As with all Open Source projects, PC-BSD also follows the principle of not shipping the proprietary codecs by default and requires that the end user install them by themselves if they want to. Here is the interesting part. To install the multimedia codecs, all I had to do was to download and install the requisite PBI file from the PBI online repository. And viola!!, I was able to not only play wmv and quick time files but also watch encrypted DVD movies as well.

I have an Nvidia graphics card and I wanted PC-BSD to harness the full potential of the graphics card. Usually you can get along very well with the Nvidia open source driver but if you want to use OpenGL programs for instance, you need to install the proprietary driver. In the PBI repository, you will find a number of builds of Nvidia proprietary drivers for PC-BSD and you can choose the best package which works for you.

I found enabling Flash to be a little tricky affair. Mainly because Adobe has not yet released Flash Player ver 9.0 for BSDs. And the native build of Flash player for BSDs is still at ver 7.0. While you can very well install this version of flash player, many flash enabled websites now a days require you to have version 8.0 or above to view them - a big handicap for BSD users. One work around you have for PC-BSD is to install the Linux version of FireFox web browser. You heard me right. It is possible to install most Linux software and run them without any modification in PC-BSD. This is made possible because PC-BSD has a Linux compatible module installed.

I installed the Linux version of the latest build of FireFox from the PBI online repository as well as the Flash player ver 9.0 from here. And I was able to view flash websites without any problem. Of course I encountered a minor glitch in that each time I open two flash based websites simultaneously, Linux version of FireFox crashes. But by and large I was able to manage as long as I had only one flash website open at any given time.

I also downloaded and installed Sun's JDK 1.5 from the PBI online repository.

Is PC-BSD a FreeBSD clone ?

At first glance, one might be tempted to pass off PC-BSD as a clone of FreeBSD with some frills thrown in, as PC-BSD uses the FreeBSD ports. And it is easy to think that if you are installing software using ports, you are essentially getting FreeBSD software. But on close scrutiny, I was able to find notable differences. Some of them are as follows :

• A GUI installer which eases the installation process.
• Use of PBIs to install many software.
• Incorporating OpenBSD's robust and powerful PF firewall instead of the firewall bundled with FreeBSD.
• Many GUI front-ends which aid package management.
• Easily start/stop and enable/disable services via its equivalent GUI.
• Use of blacklist script to automatically ban IP addresses of machines of potential crackers who try to hack into your machine.
  

Suggestions for further improvement of PC-BSD

1. The three BSDs namely FreeBSD, OpenBSD and NetBSD have their own independent ports. PC-BSD team could also start maintaining its own independent ports system instead of depending on the FreeBSD ports. One disadvantage of depending on FreeBSD ports is that you have to sometimes wait a long time before the software gets updated in the ports.
   
   Take for instance GnuCash finance software. It is not easy to create a standalone PBI of GnuCash as it has to satisfy a lot of dependencies. And as of now the FreeBSD ports have the older version (1.8) of GnuCash which is markedly different from the latest version of ver 2.0 especially in the file format which the respective versions use to save the data. And the PC-BSD team has to wait until the GnuCash port has been updated to the latest version by the FreeBSD port maintainers. Truth be told, there is a GnuCash 2.0 place holder in the ports I downloaded in PC-BSD but when I give the command :
   

   # make install clean
   
   ===>   gnucash-2.0.5_3 depends on package: guile>=1.6.8_2 - not found
   ===>   Found guile-1.6.8_1, but you need to upgrade to guile>=1.6.8_2.
   *** Error code 1
   
   Stop in /usr/ports/finance/gnucash.
   *** Error code 1
   

   ... it complains that guile package is an older version and GnuCash requires a newer version of the same. These snags could be done away with if PC-BSD maintains its own ports with periodic selective syncing with FreeBSD ports.


2. When a user enters a root password to do system administration tasks using GUI, PC-BSD should offer to remember the root password so that the user does not have to enter it the next time he want to run a program in super user mode. Many Linux distributions such as Debian and Fedora have this feature. At present, if I want to install say 10 PBI's I have to enter the root password 10 times - ie. each time I execute the PBI, it asks for root password which gets really tedious. KDE dialog has a check box which offers to "keep the password" but it doesn't seem to have any effect.
   
   
3. The PBI should have an option to install software system wide or on a per user basis. This suggestion might seem strange but in a multi-user environment, it is not possible to hand over the root password to every one. And if a user wants to try out a software by downloading the PBI, he should be allowed to install it in his home directory if he cannot enter the root password.
   
   
4. The PBI should also support execution from the command line. This is not a must have feature but it can be convenient to execute and install a PBI package in certain situations where you have booted into console mode.
   
   
5. It would be nice to have a GUI front-end which allows a lay person to write custom firewall rules for PF.
   

Epilogue

PC-BSD is turning out to be an excellent alternative to other popular Desktop OSes. After testing and using PC-BSD for some time now, I can't but admire the sheer amount of work that is put into creating, developing and molding an OS for the lay person albeit with a strong slant towards FreeBSD. The fact that PC-BSD is able to accomplish all the tasks expected by an end user - be it using the Internet for communication, listening to music, watching movies or using it for recreation purposes holds it in good stead as a viable Desktop OS.
