Leave a Comment on 5 basic steps for beginners to learn Nmap.
  1. Install Nmap: The first step to using Nmap is to install it on your system. You can download the latest version of Nmap from the official website (https://nmap.org/download.html). Nmap is available for Windows, Linux, and MacOS, and can be installed using the appropriate package manager or installer.
  2. Scan a single host: To get started with Nmap, try scanning a single host to see what ports and services are available. To do this, open a command prompt or terminal window, and enter the following command:
nmap <hostname or IP address>

For example, to scan the host “example.com”, you would enter:

nmap example.com

This will scan all 65535 ports on the host and report back which ones are open, which ones are closed, and which ones are filtered.

  1. Scan a range of hosts: To scan multiple hosts at once, you can specify a range of IP addresses or hostnames. For example, to scan all hosts in the range “192.168.0.1-100”, you would enter:
nmap 192.168.0.1-100
  1. Customize your scan: Nmap offers a wide range of options and customization settings that allow you to tailor your scan to your specific needs. For example, you can specify which ports to scan, set the scan speed, or use advanced techniques like version detection or OS detection. To see a complete list of options, enter:
nmap --help
  1. Analyze your results: Once your scan is complete, Nmap will report back with a detailed list of all the hosts and services it has discovered. You can use this information to identify potential vulnerabilities, optimize network performance, or simply get a better understanding of your network’s layout.

Overall, Nmap is a powerful and essential tool for any network administrator, offering a wide range of features and capabilities that make it an invaluable part of any network security toolkit. Whether you’re just starting out or are an experienced pro, Nmap is a tool that you won’t want to be without.

He is an Author, Inventor, UAS Engineer, Blogger//Speaker and Entrepreneur. He has completed Aircraft Maintenance Engineering (AME). After the completion of the course, He shifted to Manila Aviation, Philippines to obtain the experience of Bell 407 Helicopter and Super King Air B200 aircraft. Also, accomplished accreditations in Human Factors, Aircraft Systems, Jet Engines, and Airframe, identified with wide-body aircraft, such as A320, A340, and B737. Later on, He joined a privately held UAV Company as a UAV Technical Engineer, where, during the exploration of Unmanned Aerial Vehicles, He transmuted his ‘Manned Aircraft’ knowledge into ‘Unmanned Aircraft’ and designed ‘India’s first Drone crash course study material’. Aside from Technical work, coordinated numerous workshops and training sessions to train the Engineering students regarding the Unmanned Aviation field as well as participated in the HALE/MALE sorts UAVs venture. Presently, He is working as a Director in a private UAV Manufacturing company (VAU Technovations LTD.). His recently formed UAV include VTOL UAV with Virtual Pilot and inventions comprise ‘Blended wing body flapless VTOL UAV, controlling with bleed air motion control system’ and more. As well as he authored a book, which comprises a detailed description related to all elements of the Unmanned Aircraft System. “Since, beginning He was very much interested in to produce something new, which never been done before to change the reality. The way, which drives this sort of deduction falls under the enterprising space, where somebody controls the entire Universal laws to reimage it by his own specific manner to make outlandishly conceivable.” By keeping an innovator mindset, after the completion of the course, He joined India based Start-Up company in the Drone sector. Where he got the undertaking to design ‘UAV Courses’ and the ‘Fledged Unmanned Device’ without any assistance. It becomes very hard to work, out of your prepared space. ‘Reimagination factor’ empowered him to plan ‘Practical UAV Courses’ as well as ‘Fledged Unmanned Device’ identified with numerous applications. During the working session, organized many training sessions and Signed MOUs with different colleges to train the engineering students in his own defined way. After that joined a couple of Start-Up companies (INDIA/South Africa) in a similar area as a Pioneer to deliver them ‘Initial Stage Boosting Strategies’ to cause them to survive in the market with limited resources. Parallelly, continues to contribute his own opportunity to tackle the genuine issues, which addressed by customers. Presently, working on, to be a Global competitor in the DRONE sector by manufacturing a completely indigenous Advanced Unmanned Aircraft System with Uniquely planned calculations. Awarded by many Engineering colleges for his work in DRONE Training Domain. In 2017, ‘Entrepreneur Magazine’ printed about his Business effort in DRONE Sector. In 2018, Nominated for ‘Visakhapatnam Manufacturing Leadership Award’. His invention sheaf comprises, ‘Blended Wing Body Flapless VTOL UAV, controlling with Bleed Air Motion Control System’, to solve out the Endurance related problem with the capability of carrying both Low-speed and High-speed operations at maximum stealth mode. ‘Unmanned Aircraft System for Under Bridge Bearings Inspection’ to solve out the inspection related problem of ‘Under Bridge Bearings’, The problem was addressed by one of the construction company. An extendable robotic arm with a camera is attached with the HUB of the air vehicle, which eases the ‘Bearings’ related inspections inside the ‘confined spaces’. ‘AI DRONE with Virtual Pilot’, Virtual pilot concept makes the controlling and troubleshooting of the air-vehicle easy. The purpose for to concoct the ‘Virtual Pilot’ is to ease the controlling and troubleshooting of the air-vehicle for the Non-Engineer operator. And the invention related to the defense sector comprises, ‘Lightning Strike System’, A MALE/HALE UAV payload system that channelizes the ionized plasma through MV channels to neutralize the targets. Additionally, Related to the Agriculture sector, the commercially launched ‘AGRORECK’ series ‘Pesticide spraying’ and ‘Multi-spectral imaging DRONES’ to solve the AGRO-related problems.
