The output will be nothing fancy, just a brief summary of the active hosts. If you just want to know which remote hosts are alive in your subnet, pass the -sn flag as shown. $ nmap -open 192.168.2.107 Scan for active remote hosts

Here, we are scanning Metasploitable Linux which is an intentionally vulnerable virtual instance for penetration testing. To scan all open ports on a target, use the –open flag. To specify multiple ports, you can list them using commas as shown below. In the example below, we are scanning for port 80 on the remote host. You can instruct Nmap to explicitly scan open ports on a target host using the -p flag followed by the port number. For instance, the command below scans all the remote hosts in the 192.168.2.0 subnet. You can scan an entire subnet by making use of the CIDR notation. If you have remote hosts in a range of IP addresses, you can specify the range separated by a hyphen. If you wish to scan consecutive remote host IP address, simply suffix the address as follows: $ nmap 192.168.2.1,2,3,4 In a scenario where you have multiple remote hosts, simply pass their IP addresses on a single line as shown. The Nmap scan report includes details such as the open ports, state of the port, and the services listening on the ports. All you need is to pass the remote host IP address or domain name as the argument. Scanning a single host is pretty straightforward.

In this guide, we will scan remote hosts using Kali Linux.

Let’s now delve into some Nmap use cases. The most basic Nmap command involves scanning a single host and requires only the IP address or the hostname of the remote target as the argument. In this article, we highlight some of the useful Nmap commands that help you gather useful information about remote hosts. In fact, it comes pre-installed in Kali and Parrot OS which are operating systems dedicated to penetration testing and digital forensics. For this reason, Nmap is a valuable reconnaissance tool for penetration testing and revealing loopholes that can be exploited by hackers. Depending on the arguments used, Nmap also reveals underlying system vulnerabilities associated with outdated vulnerabilities based on CVSS (Common Vulnerability Scanning System). Network mapper, abbreviated as Nmap, is an open-source network scanning tool that scans remote hosts and probes for a wealth of information such as open ports, OS versions, and versions of services listening on the open ports.
