The anonymous part is because we'll use public DNS servers, namely 8.8.4.4 and 8.8.8.8, to perform the recursive query.įirst, we resolve using Google's public DNS server, which results in the following: # host 8.8.8.8 Let's see if we can gather some information about a specific network and remain anonymous. Using recursive DNS proxies for a stealth scan on a targetīy default, Nmap runs an rDNS (reverse-DNS) resolution on any responsive host.
We have to parse the output ourselves and extract IP addresses only.įor example: # nmap -sn 192.168.0.0/24 | awk '/Nmap scan/' For example, what if we wanted to store IP addresses from the above output to a file? This is something specific and does not belong in the man pages of Nmap. While Nmap man pages are well-written and provide many examples, there are specific things you won't find in the man pages. The use of -sP is still backward compatible and should work in the recent versions of Nmap. Mind you that -sn was known as -sP in the previous versions of Nmap. Nmap done: 256 IP addresses (7 hosts up) scanned in 9.11 seconds

MAC Address: 50:DD:FF:AA:DD:BA (Tp-link Technologies) MAC Address: 40:DD:DD:8F:FF:F5 (Asustek Computer)
MAC Address: 5C:DD:DD:FF:FF:B5 (Texas Instruments) Nmap scan report for SoundTouch-Kitchen.lan (192.168.0.160) MAC Address: 88:DD:EA:DD:CE:37 (Texas Instruments) MAC Address: 50:C7:FF:FF:15:FF (Tp-link Technologies) The output of the above command produces something like: # nmap -sn 192.168.0.0/24 If we want to run a quick scan of machines in our network without trying to see if any port is open, we run: # nmap -sn 192.168.0.0/24 Multiple networks can be scanned at once. MAC Address: 50:ff:BF:ff:ff:AC (Tp-link Technologies) Nmap scan report for Archer.lan (192.168.0.1) Running a scan without any argument except the network address yields the following: # nmap 192.168.0.0/24 Let's assume your local network is 192.168.0.0/24, and you want to run a scan on this network. You also should consult the Nmap man page by running man nmap. After installing Nmap, you can run the nmap command without arguments to display all of its options.

Zenmap for linux how to#
In the following post, we'll walk you through on how to install Nmap, use it, and, most important, get more to know about your network. The Nmap suite includes an advanced graphical user interface and results viewer ( Zenmap), a flexible data transfer, redirection, and debugging tool ( Ncat), a utility for comparing scan results ( Ndiff), and a packet generation and response analysis tool ( Nping).īesides being free, Nmap is very flexible, portable, well-documented, and easy to use. The tool is used by network administrators to inventory network devices, monitor remote host status, save the scan results for later use, and so on. Nmap is very powerful when it comes to discovering network protocols, scanning open ports, detecting operating systems running on remote machines, etc. Nmap, which stands for "Network Mapper," is an open source tool that lets you perform scans on local and remote networks.
