Welcome Guest, Login Register. Get Updates on Nmap Tweet. NMAP is a very well-known utility literally. When you get acquainted with her, you can learn it in some movie episodes. In this note, I will show you the basic techniques of work with NMAP and show some examples how to use it. In most modern distributions, NMAP is present in standard repositories. If the system you use does not apply, you can get source utility codes and some binary builds from the project download page.

Suppose you need to try to determine the type and version of the running OS on the deleted Target. The remote system survey will take some time after it is completed, you will receive a conclusion similar to the following:. As you can see, NMAP has provided a lot of information. In the presented example, NMAP performed a series of tests, on the basis of which it tried to determine the type and version of the OS used on the host.

In addition to the fact that NMAP told us the type of proposed OS, it also brought information about the network remote control, the MAC address and the manufacturer of the network interface, the list of open ports and the time spent on scanning. Here we see that the manufacturer of the network interface is HP, the operating system is Linux with a vertex version in the area 2. In general, it is usually impossible to accurately determine the version of the Linux kernel using NMAP.

In the examples given above, I scanned my own router and one of the workstations located in my network, as I have full right. In principle, you can scan any host as you wish, however, not a very good idea to scan other people\’s networks and hosts without the permission of their owners.

If you need you want for experiments, the community is ready to provide it to you at scanme. Some administrators without understanding belong to unexpected scans of their networks, so do not get out of the frames and scan the hosts that you allowed to scan. Among other things, the action of some aggressive NMAP scanning methods can go beyond the rules installed by your provider, so be attentive.

In one launch of NMAP, you can scan more than one host. If you use IP addresses in the object of scan purposes, you can transmit them to NMAP in the form of bands, for example: The first method determines the range of IP addresses C For example, if you want to scan hosts with IP addresses If you run NMAP without options, passing it only the name of the target host, the NMAP will scan the target for open network ports and listening to them. For example:.

NMAP recognizes six state states: open. At , 0. Interesting Ports on host. If you need to find out how it is possible for more details, what the service is dangling on a thorest, try using options.

These options cause NMAP instead of normal port scans, make more aggressive scanning, polishing services on a thirty port. Also, this method sometimes allows you to more accurately determine the type and version of the OS used on the target system. Also from the names of the software versions can be determined that the server works under Ubuntu Linux. Such a scanning method may be quite by the way, when you need to identify outdated software versions that work on your hosts that may be subject to known threats.

Are not sure for sure what you know about all the inhabitants of your network? Try starting NMAP with parameters \”-SP\” And it will perform the usual ping scan, defining only responding hosts without resorting to port scanning.

For example, to identify \”alive\” in the subnet If working in command line mode is not your horse, you can use the GUI utility that facilitates the construction of the NMAP command line, as well as with some bonuses such as building a graphics card network. ZenMap has pre-installed scan profiles that you can simply select from the drop-down list and may not be immersed in the subtleties of the NMAP options. Zenmap is a great tool for those who are just going to get acquainted with NMAP or just want to play with him.

While Nmap was once a Unix-only tool, a Windows version was released in and has since become the second most popular Nmap platform behind Linux.

Because of this popularity and the fact that many Windows users do not have a compiler, binary executables are distributed for each major Nmap release. We support Nmap on Windows 7 and newer, as well as Windows Server and newer. We also maintain a guide for users who must run Nmap on earlier Windows releases.

While it has improved dramatically, the Windows port is not quite as efficient as on Unix. Here are the known limitations:.

Nmap only supports ethernet interfaces including most Now Nmap must send lower-level ethernet frames instead. When using Nmap without Npcap, you cannot generally scan your own machine from itself using a loopback IP such as This is a Windows limitation that we have worked around in Npcap, which is included in the Windows self-installer.

Scan speeds on Windows are generally comparable to those on Unix, though the latter often has a slight performance edge. One exception to this is connect scan -sT , which is often much slower on Windows because of deficiencies in the Windows networking API. This is a shame, since that is the one TCP scan that works over all networking types not just ethernet, like the raw packet scans.

By default these changes are applied for you by the Nmap executable installer. These changes increase the number of ephemeral ports reserved for user applications such as Nmap and reduce the time delay before a closed connection can be reused.

Set a large value such as 0xfffe. See MS KB Set the minimum value 0xe. For many years, Nmap was a Unix-only tool, and it would likely still be that way if not for their efforts. Most Nmap users choose this option since it is so easy.

Another advantage of the self-installer is that it provides the option to install the Zenmap GUI and other tools. Simply run the installer file and let it walk you through panels for choosing an install path and installing Npcap. The installer was created with the open-source Nullsoft Scriptable Install System.

Every stable Nmap release comes with Windows command-line binaries and associated files in a Zip archive. No graphical interface is included, so you need to run nmap. Here are the step-by-step instructions for installing and executing the Nmap. Download the. Extract the zip file into the directory you want Nmap to reside in.

Nmap requires the free Npcap packet capture library. Most Windows users prefer to use the Nmap binary self-installer, but compilation from source code is an option, particularly if you plan to help with Nmap development. Some of Nmap\’s dependencies on Windows are inconvenient to build. The build files are configured to look for dependencies in this checked-out directory. If you want to build the dependencies yourself instead, you will have to reconfigure the Visual Studio project files to point to the alternate directory.

Decide whether to obtain the Nmap source code by downloading the latest release from nmap. Those are the same tar file compressed using bzip2 or gzip, respectively. The bzip2-compressed version is smaller. Uncompress the source code file you just downloaded. The source code directory and the nmap-mswinaux must be in the same parent directory. Recent releases of the free Cygwin distribution can handle both the. Use the command tar xvjf nmap-version. Alternatively, the common WinZip application can decompress these files.

While many users love Zenmap, others prefer the traditional command-line approach to executing Nmap. Here are detailed instructions for users who are unfamiliar with command-line interfaces:.

Make sure the user you are logged in as has administrative privileges on the computer user should be a member of the administrators group. Opening a Cygwin window if you installed it by clicking on the Cygwin icon on the desktop works too, although the necessary commands differ slightly from those shown here. Change to the directory you installed Nmap into. You can skip this step if Nmap is already in your command path the Zenmap isntaller adds it there by default.

Otherwise, type the following commands. The directory will also be different if you chose to install Nmap in a non-default location. Execute nmap. Figure 2.

Choose Path from the System variables section, then hit edit. Add a semi-colon and then your Nmap directory e. Open a new command prompt and you should be able to execute a command such as nmap scanme. MaxUserPort Set a large value such as 0xfffe.

Note Most users prefer installing Nmap with the self-installer discussed previously. For improved performance, apply the Nmap Registry changes discussed previously. Compiling Nmap on Windows from Source. Executing Nmap from a Windows command shell. Most users prefer installing Nmap with the self-installer discussed previously.
