![]() While nmap is having trouble here with the Linux version of Device (Linux 2.6 xD), it has successfully detected the Operating system (Linux) of my PC (ServerR-c) and interestingly, this time it has also picked my phone that I am using as the wifi hotspot. Note: OS detection in nmap requires root privileges, you will need to run nmap with sudo. Nmap has detected both devices who are connected on my network successfully, lets try the Operating System Detection feature as well. The ServerR-c (192.168.43.111) is my main computer that I am writing this tutorial from and sakura (192.168.43.17) is my laptop that is connected on the same network as my main PC. Here you can see that nmap has found 3 devices on my network. Nmap done: 256 IP addresses (2 hosts up) scanned in 17.90 seconds On Ubuntu you will find gnome-terminal, on KDE desktop environment there is Konsole, for XFCE there is xfce-terminal and so on. To do the scan we need access to a terminal (scroll down for the GUI method), most mainstream Linux distributions come with one these days. Now we have our IP range, we can begin the scan. Meaning my network can assign new devices IP from the range 192,168.43.0 – 192.168.43.225. ![]() It also states that wifi router’s broadcast (brd) address is 192.168.43.255. I am connected to wifi using the device wlp0s18f2u1, and my ip address is 192.168.43.111. Link/ether 88:51:fb:4c:4f:8f brd ff:ff:ff:ff:ff:ffģ: wlp0s18f2u1: mtu 1500 qdisc mq state UP group default qlen 1000 The output will be something like this: ~]$ ip aġ: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 ![]() In Linux we can use the ip command to do so, this command will let us find our private/local IP address which we can use to find the range. Here you can see a device with hostname MSRTK has IP address 192.168.1.8.Once nmap is installed, the next thing that we need to do is to find the local IP range of our network. You can split up subnets to customize their. You are free to scan any IP addresses you want without limitation. Nmap done: 256 IP addresses (4 hosts up) scanned in 2.41 seconds Schedule a Complete Network Scan by IP Range. Nmap scan report for ubuntu (192.168.1.5) Nmap scan report for hpprinter (192.168.1.2) For each device that responds to the ping, the output shows the hostname and IP address like so: Starting Nmap 6.40 ( ) at 12:46 GMT ![]() Ping scan just pings all the IP addresses to see if they respond. Now use the nmap command with the -sn flag (ping scan) on the whole subnet range. Now you have the IP address of your computer, you will scan the whole subnet for other devices. ![]() On Windows, go to the Control Panel, then under Network and Sharing Center, click View network connections, select your active network connection and click View status of this connection to view the IP address.On macOS, go to System Preferences then Network and select your active network connection to view the IP address.On Linux, type hostname -I into a terminal window.First find your own IP address, in other words the one of the computer you’re using to find your MSRTK Moduls IP-address: To use nmap to scan the devices on your network, you need to know the subnet you are connected to. To install on macOS or Windows, see the download page.To install on Linux, install the nmap package e.g.The nmap command (Network Mapper) is a free and open-source tool for network discovery, available for Linux, macOS, and Windows. ![]()
