Dynamic DNS updater behind a router.

I use Dynamic DNS to be able to communicate to/from my laptop to the LAN. I recently noticed that when it was plugged in at home, the address it was updating was a DHCP issued by my router. Here is the fix I used to make it work correctly.

replace the use= line in your /etc/ddclient.conf with the following.
use=web, web=checkip.dyndns.org/


Sample /etc/ddclient.conf :

protocol=zoneedit1
use=if, if=eth0
server=dynamic.zoneedit.com
login='user'
password='password'
mydomain.com

Gerix Wifi Cracker in Ubuntu 12.04

Gerix Wifi Cracker used to be in the Ubuntu repos, but isn't anymore. Here is how to install it.

If you happen to still be using WEP for your network, you might want to give the following a try to see just how weak your security really is.

Add the backtrack repos...


sudo sh -c 'echo "deb http://32.repository.backtrack-linux.org revolution main microverse non-free testing" >> /etc/apt/sources.list'

sudo sh -c 'echo "deb http://all.repository.backtrack-linux.org revolution main microverse non-free testing" >> /etc/apt/sources.list'

sudo sh -c 'echo "deb http://all.repository.backtrack-linux.org revolution main microverse non-free testing" >> /etc/apt/sources.list'

sudo apt-get update

sudo apt-get install gerix-wifi-cracker-ng

Run it with 

gksudo python /usr/share/gerix-wifi-cracker-ng/gerix.py
