Nmap Scanning on Backtrack 5 [Detailed Tutorial]



Nmap is a program that scans all of the ports in your computer and check it  whether they are open or not.

So lets start the scanning process in Backtrack 5 Environment.



Ping Scan 


Range Scan 


Stealth Scan (-sS) 


OS SCAN : It showed us which Operating system is running by 
             the host.



TCP SCAN : This scan will show all the open tcp ports . 

ADVANTAGES :

  1. Speed
  2. Free to use 
  3. Don't need priviledges
DISADVANTAGES
  1. Easily Detectable and Filterable .

FIN SCAN 



NULL SCAN


UDP SCAN
In udp scanning we use udp scan instead of tcp scan .


Protocol Scan -sO <Target Ip >


IP PROTOCOL SCAN 

This Scan is used to find the ip protocols in use .



ACK (Acknowledgement Scan)

Turn Your Cell Phone Into Jammer

 I have managed to build my own cell phone jammer, at last! And now  you  can do the same. Steps Working Principles . This cell phone jammer operates at GSM800 frequency since most mobile phones use it to operate. So the selected VCO is a sweeping oscillator, which is very effective but may be hard to construct for the beginners without nice RF-testing equipment. As a noise source you can use 45MHz clock oscillator which is driving Local Oscillator port located on a mini-circuit mixer. There is also an impedance matching network for Local Oscillator signal to pass through it. It is used to equate impedances of the clock oscillator and the port of the mixer. RF input (which is this port of the mixer) connected to the first 800MHz cell phone antenna, and the RF output is sent to the mini-circuit amplifier. This amplifier increases the output power for 15-16dbm. The amplified signal then sent to the second cell phone antenna. How It Works ?   All cell phones which use G...
