Its flexibility, power and ease of use have led to the popularity of the tool. Nmap has gained widespread popularity and have reached thousands of people. Standard service detection: nmap -sV x.x.x.x Scan 100 most common ports: nmap -F x.x.x.x Even a new administrator will be able to use the graphical version (Zenmap) with efficiency right away. Scan a range of ports: nmap -p 1-100 x.x.x.x 113 verified user reviews and ratings of features, pros, cons, pricing, support and more.
Scan targets from a text file: nmap -iL iplist.txt\ The complete summary of Nmap options can be obtained by running the command without passing any arguments.īasic usages of Nmap are discussed below: The Nmap output comprises of a list of scanned targets, with supplemental information on each depending on the options used. The Nmap command comes with lots of options that can make the utility more robust.
Nmap vs zenmap for free#
The source code is available for free and the same can be used to make modifications. Nmap is not economically targeted and it aims at providing administrators an advanced tool for their networks. Nmap package comes with a GUI called zenmap. It provides both command line and graphical (GUI) versions that can be chosen upon your preferences. Using scrips functionalities of Nmap can be extended to enable more advanced detection. * It finds out the operating system of target host. * It investigates network services on target systems and determines application name and version details. * It finds out open ports on target hosts. * It identifies hosts on a network and lists the hosts that respond to TCP/ICMP requests. Nmap is not just limited to gathering information it can be used as a vulnerability detector also. Now it has emerged as a cross platform utility available in Windows, Solaris and BSD variants. Initially written by Gordon Lyon, it was started as a utility just for Linux. It sends specially crafted packets to the target systems and analyses responses from these systems to gather the required information. It uses raw IP packets in different ways to carry out security scans and identify details like what type of hosts are available on a network, the services that are offered on the system, the operating system and the types of firewalls used in the system etc., apart from a wide variety of other characteristics. Also it can be used in ethical hacking to find out loopholes and vulnerabilities in the system. By using Nmap, attackers can easily determine what ports are open on a system.
The free and open source tool can be used for security scanning, network discovery and network exploration. These are paid tools, which are based on FOSS (Free and Open Source Software). A plethora of security tools are available in the market for network administrators to make use of. In an unsecured scenario, security tools are inevitable to safeguard your system.
