Q. Which is the best book / website from Studying Networking, so as to build a rock solid foundation.
A. I'm not sure about websites, but this book is AWESOME:
"Practical TCP/IP: Designing, Using, and Troubleshooting TCP/IP Networks on Linux and Windows"
I highly recommend it for the absolute beginner and networking-veterans. It describes *everything* in great detail, including troubleshooting tips and tools. It has screenshots and sample outputs for both Unix and Windows network tools and tons of insights from the author who's job was to troubleshoot and fix simple and complex networks.
The best part is, he teaches by example. You set up little networks and slowly grow their features and nodes.
Can you install Linux to PS3 from PS3 Hard Drive?
Q. I know Linux can be downloaded to a memory stick or burned to CD Rom and installed on PS3, but I don't have a CPU to do such.
I'm curious if theres a way to download the Linux install to the PS3 Hard Drive and install it from there?

YELLOW DOG LINUX 5.0.1
for PLAYSTATION 3
by Terra Soft Solutions, Inc.
Loveland, Colorado
INTRODUCTION
Thank you for choosing Yellow Dog Linux!
When Sony Computer Entertainment designed the PLAYSTATION®3 (PS3â¢), it
was fully intended that you, a PS3 owner could play games, watch movies, view
photos, listen to music, and run a full-featured Linux operating system that
transforms your PS3 into a home computer.
Yellow Dog Linux for PS3 combines a simple to use graphical installer with
leading-edge components and a foundation of must-have home, office, and
server applications. Everything you need to browse the web, check and
compose email, do your school homework or take your office work home is
included with more than 2000 packages on the Install DVD.
And what's more, Yellow Dog Linux is 100% open-source, meaning the source
code to every component is freely available so that if you desire to improve one
or more applications, you may do so at your choosing. This contribution back
to the open-source community leads to the improvement of Linux software
worldwide.
It's a system that has worked for more than 15 years, continuing to grow in
both quality and users every year. Linux is collectively one of the top operating
systems in use worldwide. Terra Soft is proud to be a part of this with a Fedora
Core, RPM based Yellow Dog Linux.
This Guide to Installation
This Guide to Installation is written specifically for the Sony Computer
Entertainment PLAYSTATION®3. This Guide does not offer instructions specific
to other computers (ie: Apple Power Macintosh) supported by Yellow Dog
Linux. Installation instructions for other computers are available from Terra
Soft's website.
Refer to www.terrasoftsolutions.com/support/ for updates, issues specific with
unique computer configurations, and engineering notes.
Where is Yellow Dog Linux Installed?
The drive installed in your PS3 ships with just one large partition, a logical
division of the drive into unique sectors for the organization and protection of
data.
Before you install Yellow Dog Linux, you will use the PS3 GameOS to split the
drive into 2 major partitions: one for saving game data, music, and photos; the
other for Yellow Dog Linux.
In this respect, both the GameOS and Yellow Dog Linux maintain their own
unique volumes on which to store data.
Two Operating Systems on my PS3?
Following the installation of Yellow Dog Linux on your PS3, there will be 2
operating systems: the GameOS and Yellow Dog Linux (YDL).
The GameOS is the operating system that ships pre-installed on PS3. It is also
referred to as a hypervisor, an operating system that provides a channel of
communication between the outside world (you, your game controller, the
monitor) and the built-in hardware (CPU, motherboard, RAM, hard drive, and
I/O ports).
When you use the on-screen menus, play a game, watch a movie, or listen to
music, you are doing so through the GameOS. Yellow Dog Linux runs on top of
the GameOS which provides an important communication between Linux and
the hardware.
Even if this sounds a bit technical, it is important as the GameOS provides a
layer of continuity for Linux, making the development and maintenance of Linux
for PS3 a more predictable process. This means you will enjoy a higher quality,
higher performance Linux operating system.
We hope you enjoy Yellow Dog Linux for PS3 and we look
forward to receiving your feedback.

PREPARATION
The Yellow Dog Linux Install DVD
Either remove the Install DVD from the Yellow Dog Linux (YDL) package or
prepare the Install DVD-R via a download and burn.
YDL may be purchased from the Terra Soft Store:
www.terrasoftsolutions.com/store/
... or via select retail stores worldwide (see Terra Soft's website for details).
YDL may also be downloaded via YDL.net Enhanced accounts which provide a
dedicated server for early access and Installation Support or from the public
FTP mirrors (made available two weeks after the physical product ships).
PS3 Preparation
There are just a few things you must do with your PS3 before it is prepared to
install Yellow Dog Linux.
1. Attach your PS3 to a hi-definition TV or monitor using an HDMI (digital)
or Component (5 RCA jacks) cable. Composite (yellow RCA jack) is not
supported as the resolution is too low.
2. Attach the game controller, a USB keyboard and mouse to your PS3. The
game controller will be used to conduct all GameOS functions. The USB
keyboard and mouse will be used once you enter the YDL installer.
3. Power on your PS3. If this is the first time you have used your PS3, you
will be prompted to Select a language, Select a time zone, Set the time &
date, and Set the username (more easily done with a USB keyboard).
4. If you have used your PS3, BACK UP ALL GAME, MUSIC, & PHOTO DATA
before formatting the drive as all data will be lost.
5. Select: Settings ==> System Settings ==> Format Utility ==>
Format Hard Disk ==> Yes ==> Yes
6. Then select a partition setting for the hard disk: Custom
7. You will be presented with option to "Allot 10GB to the Other OS" or
"Allot 10GB to the PS3 System." If your PS3 has a 20GB drive and you
select 10GB for the PS3 System, this leaves roughly 6.5GB for Linux (not
enough for a full install, but ample for the default YDL install).
8. Your PS3 will now format its internal drive.
9. Press "X" on the controller to EXIT which will cause your PS3 to reboot.
The bootloader installer
The bootloader installer, a piece of software that installs the bootloader (below),
is now pre-installed by Sony with the GameOS. Therefore, the GameOS is
prepared to receive the bootloader.
The bootloader
The bootloader "kboot", a piece of software that allows the GameOS to transfer
authority to Yellow Dog Linux, is now included on the YDL Install DVD in the
directory /ps3/otheros directory as "otheros.bld".
Transfer control of your PS3 to Linux
Before you install Yellow Dog Linux, you must temporarily transfer control of
your PS3 to the Yellow Dog Linux installer. Do not turn off the power nor remove
the recording medium during the installation. Interrupting the installation
process may cause damage.
1. From the GameOS menu, select:
Settings ==> System Settings ==> Install Other OS
2. Your PS3 will now scan the DVD for the bootloader installer and
bootloader.
3. Confirm discovery of "/ps3/otheros/otheros.bld".
4. Press "X" on the controller to start the installation. The PS3 screen blanks
while pulling files from the DVD.
5. You will now be prompted with:
"Other OS Installer Version x.y.z" ==> Start
... and then:
Controller check ==> License Agreement ==> Install Completed
... and then:
"Back"
6. You must now select "Other OS" in order to install YDL:
Settings ==> System Settings ==> Default System ==> Other OS
7. Power off your PS3.

Returning to the GameOS
Your PS3 will now boot to YDL each time it powers on unless you command
kboot (the bootloader) to again boot the GameOS (see BOOTING GAMEOS,
below).
To return to the GameOS, at the kboot prompt, enter:
boot-game-os [ENTER]
The PLAYSTATION®3 may be forced to return to the GameOS by holding the
power button for about 5 seconds at power on. Doing this resets your PS3 to
factory default. To return to Yellow Dog Linux, you will need to perform steps
6 and 7, above.
INSTALLATION
1. Power on your PS3.
2. Insert the YDL Install DVD into the PS3.
3. The bootloader kboot is displayed on-screen.
4. Press TAB repeatedly to cycle the 4 options: install, installtext, rescue, and
rescuetext. Press ENTER to select the desired option. If you do nothing
for 10 seconds, the bootloader will default to install.
When installing YDL, you will need a monitor or television with HDMI
(digital) or Component (5 RCA jacks) cable input in order to perform
a graphical install. If your monitor has only Composite (3 RCA jacks)
and/or running "install" at the kboot prompt does not work, running
"installtext" will cause the YDL 5 installer to run in a low-resolution text
mode. This will later require command line configuration in order to
gain a low resolution (difficult to read) graphical interface. Instructions
to do this are found at www.terrasoftsolutions.com/support/solutions/
5. When presented with the "Check Install Media" screen, select "Skip".
6. Enter Anaconda (the Yellow Dog Linux installer) and move forward with
the installation of Linux, as guided on-screen and in the next section.
Language & Keyboard Selection
Select your preferred Language and Keyboard configurations.
Partition Drive
Partitioning a drive creates logical (as compared to physical) sections on
your drive, each serving the purpose of organizing and protecting data.
NOTE: If this is the first time installing Linux on your PS3, you will be
warned, "The partition table on this device sda was unreadable ..." This is
normal. Go ahead and select "Yes" to proceed.
You may either allow the Installer to create the partitions for you by selecting
Automatic Partitioning, or conduct this effort manually via Disk Druid.
If you elect to use the Automatic Partitioning feature, you may choose from one
of three schemes:
Remove all Linux partitions: this will delete and then replace only existing
Linux partitions. Please note that if you have already installed Linux on
your PS3, this procedure will DESTROY ALL EXISTING LINUX DATA.
The GameOS and game data will not be harmed.
Remove all partitions: on a PS3 (as compared to a Mac) this will produce
the same result as "Remove all Linux partitions" (above) as the GameOS
cannot be affected by the Linux install
How many types of OS are there?
Q. There are at present Unix, Windows, Mac and Linux that are used in computers today.
Are there any other OS used in computers today? What are they? Are they also free, like Linux?
A. I'd love to argue that it's a matter of opinion. Mac OS is built on BSD Unix, as has just about every OS which Steve Jobs has been associated with since NeXTStep. Linux was always intended as a kernel for a free Unix. It was developed in the Minix community, but Andy Tannenbaum who developed Minix as, among other things, a teaching tool, had problems with it. To be called a Unix you must pass a series of tests. Having your OS tested costs money -- like thousands of dollars. One or two distributions -- usually for the enterprise -- have been tested and found to be Unix operating systems. Even Ubuntu, though, can't budget for it and so whether Linux is a Unix is -- mostly -- undetermined.
In addition, the GNU/Linux Operating System is mostly built on Gnu Tools, and there are alternative kernels for running it, such as Hurd which like tools such as GCC and tar you can get from the Free Software Foundation itself.
On top of this there are specialized OSes, such as Minix or Citrix and older Operating systems such as AmigaOS and BeOS which have been released to the technical public for further development.
Bluntly, Microsoft is responsible for this situation. To some extent Apple as well: they drove BeOS out of business together because they did not want it running on their machines, but Microsoft more generally is involved in a variety of activities to make it as expensive as possible to run alternatives to Windows on any machine whether through disinformation -- as in specifying so many patents are being infringed on by Linux -- which would mean the Linux kernel which doesn't do things the way Windows does -- or other aspects of it "Get the Facts" campaign and deals with OEMs which make Windows relatively affordable for pre-installation ONLY if they pay a royalty on every computer made by them -- period. Read the anti-trust trial and remember they were convicted of monopoly practices -- and a heavily politicized Justice Department does not want serious penalties imposed on them.
Microsoft has been stifling competition while ignoring, increasingly whole segments of the market, such as the moderately tech-savvy, who are therefore forced to find or create an operating system which will meet their needs. Since Unix has been widely used and rewritten in our educational system since the seventies, most people who need it have turned to one or another variation of it. That is why I'm going to venture the opinion that your question may be unanswerable. It is either very large or very small: with Windows and Unix being the two most used.
