In this section, we're going to learn some of the basic Nmap commands that can be used to discover clients that are connected to our network, and also discover the open ports on these clients. Nmap can be used to bypass firewalls, as well as all kinds of protection and security measures. Using the Nmap, we can gather information about any client that is within our network or outside our network, and we can gather information about clients just by knowing their IP. Nmap is used to gather information about any device. After saving a scan you can come back to it later to view it.Nmap(Network Mapper) is the second program that we're going to look. Type in a name for the scan (such as myscan.xml), and click Save. This shows you some additional details on the host.ġ0) With the Host Details tab still selected, click on a few different host IP addresses to see the available information.ġ2) Browse to a location on your computer. You can also click Legend on the top right to see what each of the icons mean.ġ0) Select the Host Details tab. Nmap correctly identified it as a network router and also indicated that it is running an embedded website on ports 80 and 44.Ĩ) Select a few different host IP addresses in your network to see the available information.ĩ) Select the Topology tab. The following graphic shows the result for one of the hosts in my network. The examples page lists some basic scan commands and describes the purpose of the switches within the commands.ħ) When the scan completes, take a look at one of the host IP addresses and click on Ports/Hosts. While the scan runs, you might like to look at the online manual. Other books are also available on Nmap here. Gordon Fyodor Lyon created Nmap and his comprehensive book Nmap Network Scanning: The Official Nmap Project Guide to Network Discovery and Security Scanning is the definitive guide. This short lab doesn’t show you everything about nmap, but instead just introduces some basics. This will take a little while to complete.Īn important point to realize is that Nmap is a very rich application. Warning.Ensure you have authorization before running a scan on a network.Ħ) Select Intense Scan and click Scan. Some of the scans and their related commands are listed in the following table. Select each available scan and notice how the commands change slightly. You can enter the same command at the command line to run a scan.ĥ) Select the dropdown box next to Intense scan. With the Intense scan selected, it looks like this: Notice how the Command text box is populated with a command after you entered the Target. On Windows 10, you can do so by clicking on the Search icon, typing zenmap, and clicking on Nmap – Zenmap GUI.Ĥ) Enter your network ID into the Target text box as shown in the following graphic. These are the most commonly used network IDs in private networks.ģ) Start Zenmap. If you don’t know how to do so, you can use the Windows Command Prompt Commands lab.Īs an example, if your IP address is 192.168.1.5 with a subnet mask of 255.255.255.0, your network ID is 192.168.1.0/24. If you haven’t, you can follow the instructions in the Download and Install Nmap lab.ġ) Use ipconfig to identify your IP address and subnet mask. Prerequisites. This lab assumes you have downloaded and installed Nmap. ![]() Ideally, you would run this within a private network such as one at your home or within a controlled lab environment. You may face legal challenges if you run network scans on a network that you don’t own or control without authorization. Do not run this lab in a corporate network without express authorization to do so. You can use this lab to run a scan and explore the output using Zenmap. This exercise complements material in the CompTIA Security+: Get Certified Get Ahead: SY0-501 Study Guide. ![]()
