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:
[andrew@alarm ~]$ sudo pacman -S samba warning: samba-3.6.3-2 is up to date -- reinstalling resolving dependencies... looking for inter-conflicts...

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:
tar xvfz "the archive"
In the case of a .tar just remove the z. it should look like this:
tar xvf "the the archive"
For a .tar.bz2:
tar xvfj "the archive"
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:
[root@PogoLab ~]# pacman -S xfce4 :: There are 17 members in group xfce4: :: Repository extra 1) exo 2) garcon 3) gtk2-xfce-engine 4) gtk3-xfce-engine 5) terminal 6) thunar 7) tumbler 8) xfce-utils 9) xfce4-appfinder 10) xfce4-mixer 11) xfce4-panel 12) xfce4-session 13) xfce4-settings 14) xfconf 15) xfdesktop 16) xfwm4 17) xfwm4-themes Enter a selection (default=all): resolving dependencies... looking for inter-conflicts...

However, for most users it is ==> best to install xorg as an x-server. Please install either xorg-xinit ==> as minimal environment or the xorg meta package. pacman -S xorg-xinit -- or -- pacman -S xorg Optional dependencies for xfce-utils perl: for migration scripts xscreensaver: for locking screen with xflock4 gnome-screensaver: for locking screen with xflock4 xlockmore: for locking screen with xflock4 (14/21) installing xfce4-appfinder [################################################################] 100% (15/21) installing xfce4-panel [################################################################] 100% (16/21) installing xfce4-mixer [################################################################] 100% Optional dependencies for xfce4-mixer gstreamer0.10-base-plugins: to support basic audio hardware gstreamer0.10-good-plugins: well supported hardware gstreamer0.10-bad-plugins: not so well supported hardware gstreamer0.10-ugly-plugins: might contain questionable license hardware (17/21) installing xfce4-session [################################################################] 100% Optional dependencies for xfce4-session fortune-mod: for xfce4-tips (18/21) installing xfce4-settings [################################################################] 100% Optional dependencies for xfce4-settings libcanberra: for sound control (19/21) installing xfdesktop [################################################################] 100% Optional dependencies for xfdesktop xfce4-panel: panel menu plugin (20/21) installing xfwm4 [################################################################] 100% (21/21) installing xfwm4-themes [################################################################] 100% [root@PogoLab ~]# sudo xfce4-panel
You should then be greeted by a lovely xfce panel interface to launch applications from.
