The above Python code can be changed to scan multiple hosts instead of one single host, just with an alteration to the line that begins scan_range and adding a space in between each host. Using Python To Scan Multiple Hosts Multiple Individual Hosts nmap scan results Īs can be seen from the returned JSON, nmap managed to see 192.168.0.28, could tell the device was up, that port 22 (SSH) was open, the type of SSH in use (OpenSSH) and the operating system (Raspbian) in use. The results from the scan will be outputted in JSON format. Note: nmap can take a few minutes to scan an individual host depending on the options given to it. #!/usr/bin/python3 # geektechstuff nmap import nmap nm = nmap.PortScanner() scan_range = nm.scan(hosts= "192.168.0.28" ) print (scan_range) Using nmap in Python to scan a host Using Python To Scan A Single Hostįor my first Python script I am going to scan a Raspberry Pi that is on IP address 192.168.0.28. pip3 uninstall nmap to uninstall the library. If you install the wrong library via pip3, then use pip3 uninstall library_name, e.g. python-nmap used to access nmap and scans from Python3 –.nmap maps numbers from one range to another –.If you want to see what the difference between the packages is: Installing Python Nmap pip3 install python-nmap pip3 install python-nmapīe careful at this stage Python has a package called nmap which is not the package we are looking for. If you want to use nmap on its own, then open a terminal / command line and type nmap. Nmap is a program that can be used without having to write any Python and at some point in the future I may do a blog post on it. If you don’t have these installed then: Installing nmap sudo apt-get install nmap sudo apt-get install nmap This project requires nmap and the Python nmap library. The same details should work on the majority of Linux systems with Python, although you may need to replace apt with yum etc… in commands. I TAKE NO RESPONSIBILITY FOR YOUR ACTIONS.įor this project I am using my home test network and running Python 3 on a Raspberry Pi (Raspbian Linux). I previously created a basic port scanner in Python, but in this blog post I am going to look at using Python with nmap to see some of what it can do.īefore proceeding I need to make this very clear:ĭO NOT USE THE BELOW INFORMATION TO ATTACK, MONITOR OR BREAK INTO ANY COMPUTER / NETWORK / DEVICE THAT DOES NOT BELONG TO YOU. Nmap is a powerful software tool that can be used to scan a network for hosts, see what ports they have open and even try to identify what operating system the hosts have running.
