As beautiful as NTP is, NTP chatter can pollute your network traffic.
Forget removing NTP services, that is too dramatic for the system. A simple hack is to edit the /etc/ntp.conf file and remove the servers.
sudo nano /etc/ntp.conf
scroll down and hash out the lines like below:
# You do need to talk to an NTP server or two (or three).
#server ntp.your-provider.example
# pool.ntp.org maps to about 1000 low-stratum NTP servers. Your server will
# pick a different set every time it starts up. Please consider joining the
# pool: <http://www.pool.ntp.org/join.html>
#server 0.debian.pool.ntp.org iburst
#server 1.debian.pool.ntp.org iburst
#server 2.debian.pool.ntp.org iburst
#server 3.debian.pool.ntp.org iburst
Control-X and yes to save
Restart NTP:
sudo /etc/init.d/ntp restart
Check syslog
cat /var/log/syslog

Compiling mdk3 on Raspberry Pi Raspberian for a wifi hell
Compiling mdk3 on Raspberry Pi Raspberian. Tested on the on the stock upgraded Raspbian distro kernel 3.6.11+.
After you get aircrack-ng suite installed and working, this is a no-brainer.
wget http://homepages.tu-darmstadt.de/~p_larbig/wlan/mdk3-v6.tar.bz2
extract
tar -xvjf mdk3-v6.tar.bz2
cd mdk3-v6
make
then move the mdk3 file somewhere where the shell can pick it up like
/usr/local/bin/

Compiling aircrack-ng suite on Raspberry Pi Raspbian
Why, because you can. I'm doing this on the stock upgraded Raspbian distro kernel 3.6.11+.
Prerequisites are a brain, knowledge of Linux and Raspberry Pi. Casual tech self-abusers should go and do some research first and yes the Pi is helping them come out the woodwork.
Compiling from the source down not work, it has not been upgraded for a while. Just check out the SVN.
sudo apt-get upgrade
sudo apt-get update
sudo apt-get install libssl-dev subversion iw
svn co http://trac.aircrack-ng.org/svn/trunk aircrack-ng
cd aircrack-ng
make
sudo make install
airmon-ng is no longer compiled during make by the looks of it, but it is in aircrack-ng/scripts
You can make it executable by doing a chmod +x airmon-ng, then copying it to the same path where aircrack-ng is natively installed. i.e
/usr/local/bin/
To get airodump-ng to work properly, you may need to kill all the services that airmon-ng complains about then it is running.
Go to /etc/init.d and
sudo ./ifplugd stop
then sudo killall all the rest of the processes that airmon-ng complains about
PID Name
1589 ifplugd
1617 ifplugd
2380 dhclient
16076 ifplugd
16088 wpa_supplicant
16146 wpa_cli
Process with PID 16076 (ifplugd) is running on interface wlan0
Process with PID 16088 (wpa_supplicant) is running on interface wlan0
Process with PID 16146 (wpa_cli) is running on interface wlan0
Seems to work ok
pi@raspberrypi /etc/init.d $ sudo aireplay-ng -9 mon0

Using crunch to create a word list containing all the mobile phone numbers in Australia
crunch 10 10 0123456789 -t 04%%%%%%%%
where:
"10 10" fixes the length to 10 digits
"0123456789" uses all these numbers in the % locations
"-t 04%%%%%%%%" denotes the strings to contain 04XXXXXXXX
The same can be done with local phone numbers.

Notes for configuring udev rules for em28xx USB capture card
Goal:
to create static /dev/video10 for plug in USB capture device em28xx. Static video card location using udev rules ensures that the correct video device is utilised during reboots. Used for motion program www.lavrsen.dk
Soloution:
auto create a symlink from kernel assigned video address to /dev/video10 when em28xx is plugged in.
Plug in device and note video number assignment i.e. video0
then use this command to search for variables that can uniquely identify this device.
udevadm info -a -p $(udevadm info -q path -n /dev/video0)
Create udev rule:
KERNEL=="video[0-9]*", DRIVERS=="em28xx", SYMLINK+="video10"
Where:
KERNEL=="video[0-9]*" binds this rule to only video devices
DRIVERS=="em28xx" bind the rule to devices using driver em28xx
SYMLINK+="video10" creates a symlink from /dev/videoX to /dev/video10
Does it work:
ls /dev/video*
sudo service udev restart

How to disable FaceBook typeahead autocomplete using adblock
I find autocompletes sometimes useful, but it pissed me off when they modify the way I type or cause long pauses and unintuitive searches.
Facebook is no exception, their autocomplete search is crap and there is no way of disabling it in settings.
The autocomplete can be disabled using a simple adblock filter.
||facebook.com/ajax/typeahead/search.php*
Done.
