So... I use my N900 primarily as PMP, VNC client and pentesting device these days. Here's a couple of scripts I cobbled together to make things easier.

# msscan | DOWNLOAD
Comprises of two simple yet useful shell scripts: msscan and msexploit.
msscan relies on nmap in order to scan network for MS08_067 vulnerability.
Don't use nmap 5.59BETA1 from extras-testing; use either 5.50 from extras or this one (hastily compiled & packaged 6.20BETA1).

Usage (either as user with sudo and full path or as root):
msscan - scans the network you're currently connected to
msscan 192.168.1.0/24 - scans specified network
msscan 192.168.1.18 - scans single machine

msexploit runs Metasploit framework targetting specified machine with MS08_067 exploit. It assumes framework is located in /opt/msf. Any version should work, I currently use 4.2.0. I suggest to thin out exploits dir to only include essential things, it will take ages to load the modules tree otherwise.

Usage (doesn't need root):
msexploit 192.168.1.18


# mon-toggle | DOWNLOAD
Tapping on the icon loads/unloads packet injection modules (assumed to reside in /opt/packet-injection-modules/`uname -a`/) and toggles monitor mode. If you have aircrack suite installed it uses airmon-ng start wlan0, if not - iwconfig wlan0 mode monitor.
Originally the icon changed to reflect current state of interface but - as it would tend to wear out emmc (writing to .desktop file, gtk-icon-cache-update on each occasion) - I decided to drop it.


# battlow.sh
Sometimes I don't use my N900 for a long time, so I made it drop me a line when it's hungry (with a little help of Alarmed):
