=====hpc0 Keywords=====
====hpc0 LAMP server====

===Definition===

Linux, Apache Mysql and PHP server

===Demonstration===
  * Unordered List Iteminstall Apache: apt-get install apache2
  * install Mysql: apt-get install mysql-server
  * install PHP: apt-get install php5 php-pear php5-suhosin AND apt-get install php5-mysql so mysql and php play nice like they should.
  * Once your system or VM is configured with these programs you can establish a database and begin serving web pages! 

**The default location for your web server is**// /var/www/index.html// 
====hpc0 SAMBA server====

===Definition===
SAMBA is an SMB/CIFS client/server for Linux and UNIX boxes. SAMBA will often been seen as the default sharing method for local Linux nodes in a windows dominated network. 
===Demonstration===
I installed SAMBA on my headless PogoServer that runs arch Linux; I'll show you the outout:

You can now share the files of your Linux user with windows clients!

====hpc0 Extraction fun with .tar.gz .tar.bz2 and .tar====

We can't always rely on package managers to do our dirty work when installing new software or programs... 

===Definition===
Sometimes when you're installing something new you need to extract it from a tar ball before working with it.
===Demonstration===
For .tar.gz one must simply enter:
<cli>
tar xvfz "the archive"
</cli>

In the case of a .tar just remove the z. it should look like this:
<cli>
tar xvf "the the archive"
</cli>

For a .tar.bz2:

<cli>
tar xvfj "the archive"
</cli>

Then enter the directory the untar has produced. You should be greeted by a bunch of files including the make and install files.

====hpc0 Make====

===Definition===
Make is a tool to recompile programs for installation.
===Demonstration===
Here are some make options I find useful:
  * You can tell make to run in another directory using -C
  * -f to pick the file you'd like to make 
  * -i will allow you to ignore errors whilst making things.
====hpc0 ssh port forwarding====

===Definition===
ssh port forwarding allows you to access port on a remote network via ssh.

===Demonstration===
Shown below is opening port 25565 on 10.80.3.34 through lab46

====hpc0 Window manager forwarding====
You can forward an entire window manager via you ssh session onto X11

===Definition===
On a remote system you may need more then a terminal for specific applications that demand graphics. All one needs to do is forward their Window manager via their secure shell! 

===Demonstration===
Just grab a package manager of your choice and go to town! I'm going to use Xfce4 in my example:
<cli>
[root@PogoLab ~]# pacman -S xfce4

You should then be greeted by a lovely xfce panel interface to launch applications from.
====hpc0 Keyword 15====
Identification of chosen keyword (unless you update the section heading above).

===Definition===
Definition (in your own words) of the chosen keyword.

===Demonstration===
Demonstration of the chosen keyword.

If you wish to aid your definition with a code sample, you can do so by using a wiki **code** block, an example follows:

<code c>
/*
 * Sample code block
 */
#include <stdio.h>

int main()
{
    return(0);
}
</code>

Alternatively (or additionally), if you want to demonstrate something on the command-line, you can do so as follows:

<cli>
lab46:~$ cd src
lab46:~/src$ gcc -o hello hello.c
lab46:~/src$ ./hello
Hello, World!
lab46:~/src$ 
</cli>
