Nmap done: 256 IP addresses (8 hosts up) scanned in 14.94 seconds In this next probe, we're going to skip the -sn qualifier and take a look at the services that are running on each of these systems to better understand what these systems are. Most of the systems you end up probing will likely be using dynamically-assigned IP addresses (the local system might be as well), so you might see them changing, but you can get an idea what they are. In this scan, we see that only two systems are displaying with host names - butterfly (the system on which the scan is being run) and _gateway (a name provided for the router). Nmap done: 256 IP addresses (9 hosts up) scanned in 4.28 secondsĪnd if you only want a list of IP addresses, you can modify that command to look like this: $ nmap -sn 192.168.0.0/24 | grep report | awk '' Nmap scan report for butterfly (192.168.0.16) Even if you only have one to three home computers, what about your routers, cell phones, tablets, and other devices? What might you discover about them? What is discoverable? Let's take a quick look and see.įirst, the quickest nmap scan uses a couple options to tell nmap that you only want a listing of IP addresses. What would you expect to find if you were to use the tool at home? The results might be far more interesting than you imagine. It's typically used in corporate settings for collecting information on systems and doing security analysis.īut here's an interesting idea.

In fact, it's considered a standard security tool and is a free and open-source security scanner.

Originally released in 1997, nmap has since become available for Windows and other Unix variants, as well. Sysadmins have been installing nmap on Linux for more than 20 years.

OS detection - determining the operating system along with some hardware characteristics.

Version detection - identifying applications and their versions.

Port scanning - identifying services that are available for use.

Host discovery - probing by IP address and providing information on the systems that respond.Nmap makes it easy to detect changes, as well as new systems on the network. It can also help identify rogue systems and vulnerabilities. The tool provides information on the systems and services that are running (i.e., open ports). Nmap, the 'network mapper,' has long been used on corporate networks to collect information on desktop systems and servers.
