Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Patching kernel, Wifi, and No Sound with Flash+Firefox+Linux
I'm fairly new to Linux, been using the Mint Gloria distro which works off of Ubuntu framework I believe. Anyway, I have a few issues I need to kink out at the moment.
1. No sound in Flash 10, Firefox 3.0.11. I am using Gnome, if that matters. Linux Mint 7 running w/ Kernel: 2.6.28-13-generic.
I downloaded the file: libflashsupport_1.0~2219-2.tar-1
I'm unsure how to move it in commands properly, and install it.
2. I need help upgrading my kernel to a version I got downloaded, Linux Kernel 2.6.30. I don't know how to move the file to my source directory with commands, it says I don't have permission?! Weird, because I am using sudo root before using the command MV or CP. I have two files in my user name's folder, "/home/fox".
3. I need help with wireless card driver and a .patch file. I don't understand how to once again move the file to usr/src, then I do a cd linux, and should be able to apply my patch with a command..? I'm a little confused and need help. The files I need to patch are:

Welcome to LQ. First a few basics. I'll use the kernel as a worked example.
Today you are using the 2.6.28-13-generic kernel. Notice the numbers that are important.
Thats a version 2.6.28 kernel.
You have sources for a more recent 2.6.30 kernel which will replace your 2.6.28-23.and a patch of unknown functionality that appears as if it should apply to 2.6.30.
Patches are made against specific versions of packages. They may or may not apply to other versions. They may not even be required (because they are already included) in later versions.
Its very unlikely that b43-injection-22.214.171.124.patch mac80211_126.96.36.199_frag.patch will apply to your 2.6.30 because the patches are intended for a much older kernel. As I said, they may be in 2.6.30.
With that, one final piece of advice while you still have a lot to learn is to work on one problem at a time. This prevents you getting confused over what action fixed what problem. When that happens, the learning gets difficult.
Make up your mind which is the most pressing problem and post back
Good idea. Thanks for your guys' advice. My biggest issue right now in order would be the sound in Firefox Flash.
Then my wifi card. The only reason I needed to patch this driver is to support packet injection. I highly doubt the linux kernel includes this in the 2.6.30 version, because it's a special driver for my card I found online.
I just figured I needed to update my kernel for security reasons, or updates. But if it's no big deal then I won't even bother with it.
Really I just wanted the flash sound to be fixed and then my wifi card. My kids are upset all their Flash games have no sound.
OK this is strange. 1. My flash sound seems to work fine now.?! Okay. And also, when I try to kill processes in System Monitor, I don't know if this is normal but it will close the window and on the start panel, it says "Starting Administrative Application" after the prompt "are you sure you want to end process?" So it closes my System Monitor, and doesn't open it again. I'm not sure if that was normal, but it definitely is not killing processes, or ending processes.
I use a terminal, the command [CODE]ps -Alf[/COD]to discover the ID of the process I want to kill, then the
command. Thats a nice polite kill, it asks the process to please terminate normally by sending it a SIGTERM signal.
If that fails
kill -9 <PID>
is the next one to try. Thats a "go fo jail, go directly to jail, do not pass go, do not collect 200 <insert local currency>" sort of kill. It instructs the kernel to kill that task, the task cannot tidy up before it exits. On occasions even that fails. The next step is to kill the parent process. If the parent process is PID 1, you must reboot. PID 1 is always init. Its a really bad idea to kill that.
Note that tasks flagged as Zombies cannot be killed. They have already died and almost all the memory they used has been freed, its just that their parents have not collected the return values yet.
If you have persistent zombie tasks, you must kill their parents.
Thanks Neddy for the process info. What's weird about the flash sound, that one post I said it worked, so I rebooted and it's back to the same old no sound in flash. I'm not sure what I did differently to make it work. I still have no clue how to patch my wifi driver to support packet injection...
In terminal, I copied my new kernel (linux-2.6.30.tar.bz2) to folder (/usr/src/linux-source-2.6.28).
Then I change directories (cd /usr/src/linux-source-2.6.28) and do command "make", and it runs through that I'm guessing fine.
Then I command to (make install) and it returns to me this: (sh /usr/src/linux-source-2.6.28/arch/x86/boot/install.sh 188.8.131.52 arch/x86/boot/bzImage System.map "/boot")
I'm not quite sure what that means this is my first kernel patching. I rebooted and command in terminal, (uname -r) to get my kernel version and it says still, (2.6.28-13-generic). Shouldn't it be 2.6.30? Maybe I'm not doing something properly here.
If it refuses to create the link (ln -s file....to link...)
you may need to remove the old 2.6.28/9 kernel first.
as root (sudo or su (and enter password)then
rm -rf /usr/src/linux
then go back to the linking stage and begin again.
Also there are modules and other files linked to and from the sources.
It's better not to mix up the versions.
I went ahead and did the "rm -rf /usr/src/linux" command, and then went back to your directions to static link and that worked. checked both directories and they are now the same. But I notice there is not a "boot" folder, therefore when I command to "cp /boot/.config /boot/.config.bak" to make a backup it returns again,
(cp: cannot stat `/boot/.config': No such file or directory)
maybe it's because I'm new to Linux, or maybe there's a communication gap from AUS to US, but you are confusing me! I thought I already did that, but maybe if I go get some fresh air and come back to this, it might make more sense to me. Thanks for your advice!
