To make sure you specified the correct hosts before scanning, use the list scan option ( -sL), which only lists the targets without running a scan: $ nmap -sL 10.8-10.10,11,12.0/28 192.168.1-2.100,101 The following command targets the same hosts as the one above: $ nmap 192.168.10,11,12.1 To specify an octet range use the dash character. You can use the CIDR notation to specify a network range: $ nmap 192.168.10.0/24 The simplest option is to pass one or more target addresses or domain names: nmap 192.168.10.121 host.to.scan Nmap treats all arguments that are not options as target hosts.Īrguments are considered options if they begin with a single or double dash ( -, -).

To specify an IPv6 host use the -6 option: $ sudo nmap -6 fd12:3456:789a:1::1 Specifying Target Hosts To perform a UDP scan, invoke the command with the ( -sU) option as a root user: $ sudo nmap -sU 192.168.10.121įor a complete list of port scanning methods, visit the Nmap documentation page . sS is turned on by default when nmap is invoked as a user with administrative privileges: $ sudo nmap 192.168.10.121įor more detailed output, use the increase the verbosity with -v or -vv: $ sudo nmap -vv 192.168.10.121 The most popular scan option is the TCP SYN scan ( -sS) that is faster than the connect option and works against all compliant TCP stacks. Nmap done: 1 IP address (1 host up) scanned in 1.78 seconds The output will look something like this, including basic information about the scan and a list of open and filtered TCP ports. The ( -sT) is turned on by default in unprivileged mode. When invoked as a non-root user that does not have raw packet privileges, nmap runs TCP connect scan. The most basic example of using Nmap is to scan a single target as a standard user without specifying any options: $ nmap The simplified syntax of the nmap command is as follows: $ nmap Nmap is typically used to audit network security, network mapping, identify open ports, and search for online devices.
