For this, nmap supports CIDR-style addressing. Sometimes you want to scan a whole network of adjacent hosts. The simplest case is to specify a target IP address or hostname for scanning. Syntax nmap Options: target specification -iL Įverything on the nmap command-line that isn't an option (or option argument) is treated as a target host specification. The only nmap arguments used in this example are -A, to enable OS and version detection, script scanning, and traceroute -T4 for faster execution and then the two target hostnames.

In addition to the interesting ports table, nmap can provide further information on targets, including reverse DNS names, operating system guesses, device types, and MAC addresses.Ī typical nmap scan is shown below. When an IP protocol scan is requested ( -sO), nmap provides information on supported IP protocols rather than listening ports.

The port table may also include software version details when version detection is requested. nmap reports the state combinations open|filtered and closed|filtered when it cannot determine which of the two states describe a port. When they are responsive to nmap's probes, but nmap cannot determine whether they are open or closed. Open means that an application on the target machine is listening for connections/packets on that port.įiltered means that a firewall, filter, or other network obstacle is blocking the port so that nmap cannot tell whether it is open or closed.Ĭlosed ports have no application listening on them, though they could open up at any time. The state is either open, filtered, closed, or unfiltered.
That table lists the port number and protocol, service name, and state. Key among that information is the "interesting ports table". The output from nmap is a list of scanned targets, with supplemental information on each depending on the options used.

While nmap is commonly used for security audits, many systems and network administrators find it useful for routine tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services ( application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/ firewalls are in use, and several other characteristics. It was designed to rapidly scan large networks, although it works fine to scan single hosts. Nmap ("Network Mapper") is an open source tool for network exploration and security auditing.
