Arch LAMP: Super quick start guide

  • Posted on October 7, 2015 at 19:14

Get your terminal ready…

Install necessary packages

# pacman -S --noconfirm apache
# pacman -S --noconfirm mysql

Set DocumentRoot in /etc/http/conf/httpd.conf

Afterwards continue install PHP stuff…

# pacman -S --noconfirm php-apache
# pacman -S --noconfirm php
# pacman -S --noconfirm php-gd

Uncomment some extensions (modules) in /etc/php/php.ini

extension=gd.so
extension=iconv.so
extension=mysql.so
extension=openssl.so
extension=pdo_mysql.so
extension=soap.so

Now it’s time to configure your Virtual Hosts in /etc/httpd/conf/extra/httpd-vhosts.conf
When all is done, check your configuration and make Apache en MySQL startup automatically from now on

# apachectl configtest
# systemctl enable httpd
# systemctl enable mysql

Done! Happy webserving!

Deduplicating: EWF vs Raw

  • Posted on August 4, 2015 at 14:24

Is ‘good old’ Expert Witness Format still the preferred choice?

In the recent years huge centralized storage has become pretty much a standard everywhere. And pretty much everywhere EWF has become standard for forensics imaging.
I wonder if this is still the most optimal combination from the perspective of storage-efficiency.

How does deduplicating perform on ewf-images compared to raw? In fact, my assumption is: The more raw images saved to a deduplicating volume, the more efficient duplicating will do its job.

 

Let’s bring them to the test!

EnCase
After booting up with a Windows 7 machine, I imaged the boot disk using EnCase 6. (run 1)
Immediately after, I initiated a second acquisition using the same EnCase session (run 2)
All settings for acquisition are kept to default, using ‘Good compression’ and a split size of 640MB.

FTK Imager
After EnCase finished both acquisition sessions successfully, I started two acquisition sessions with FTK Imager using the same approach: Start one, When it runs, start session number two.

Changing WordPress Header-text

  • Posted on September 3, 2014 at 18:38

Status change

Up until about a year ago I thought of myself as an IT-guy lacking ambition. You may have read about it.
But things can change! People can change. Your status can change…

But what if you have your status listed as an under-title in your WordPress-blog?
You would update, you say?
Yes, but how in the world can you do that in WordPress?

 

Problem

To cut a long story short; I didn’t really find an easy way on changing the layout of what WorPress calls the Header-text. Of course, changing the text is not a problem. But specifically changing the layout or making it an hyperlink. That’s where it gets troubling.

Finding the header-text in the database was doable:

MySQL Query: Header text

Updating using SQL was also a peace of cake. But inserting HTML-code appeared to be ‘impossible’.
WordPress, or Apache, or PHP, whoever you want to blame, just renders the HTML to unformatted text. And that is not cool!

 

Solution

I just edited the header.php file, and added raw HTML.
File: [apacheroot]/wordpress/wp-content/themes/purple-pastels/header.php

VIM Screenshot of header.php

This is particularly a solution that I am not proud of. But I am proud of the result!

Just have to keep in mind that an update of the theme my so beloved updated header-text will be gone.
Therefor I documented all this.

GRUB: Change Splash-screen

  • Posted on July 26, 2014 at 02:37

SPLASH-SCREEN

  • Make sure you make it with GIMP Creating with Photoshop and saving (in different formats) never worked for me. Even opening the Photoshop-image with GIMP and saving it afterwards was not good enough for GRUB.
  • You can place the image everywhere. If you want to place it with the original grub-splashes, this is a good place: /usr/share/images/desktop-base.
  •  Then edit /etc/default/grub. Add the line:
GRUB_BACKGROUND="your_image.jpg"
  • Update GRUB
# update-grub2

 

GRUB-MENU

  •  Create a file called /boot/grub/custom.cfg and add the lines:
set color_normal=light-black/black
set color_highlight=white/black

 

MENU-ENTRIES

Maybe you would like to change the menu entries:
Edit /etc/grub.d/10_linux
(You can find them starting with title=. I added LISA for this example)

linux_entry ()
{
  os="$1"
  version="$2"
  recovery="$3"
  args="$4"
  if ${recovery} ; then
    title="$(gettext_quoted "LISA %s, with Linux %s (recovery mode)")"
  else
    title="$(gettext_quoted "LISA %s, with Linux %s")"
  fi

 

And then when you reboot things may look like this:
(If you’re lucky)

lisa_grub_splash

Start Debian in text-mode

  • Posted on January 6, 2014 at 21:56

Edit /etc/default/grub file, locate the following line:

GRUB_CMDLINE_LINUX_DEFAULT=”quiet”

and change it to:

GRUB_CMDLINE_LINUX_DEFAULT=”quiet text”

and don’t forget to run ‘update-grub’ afterwards to update.
