Three devicesĪre Windows-based systems, three devices are Linux based systems, and two had operating systems that Alternatively, follow the blue lines, as they indicate the routes the network device makes.NMAP scan indicates that there are a total of 8 devices on the 192.168.27/24 network. Highlight the device you ran the trace on, right click and select “Traceroute” to view the hops the device makes. In the Topology tab, Zenmap will build a web of all the different network devices it discovers by pinging and tracing. When it finishes up, click the “Topology” tab.

Next, select “Quick traceroute” in the profile menu and click scan. To run a traceroute, enter an IP address/hostname in the target section. Better yet, each traceroute run on a network device will be highlighted in the Topology tab.

It also makes a great GUI tool for running traceroutes. Zenmap can do much more than scan open ports. View the port scan output by selecting the “Ports/Hosts” tab.Īlternatively, run a detailed port scan on a network by selecting the “Intense scan” option in the profile drop-down menu. Quick scans in Zenmap happen quite fast and often find openings by scanning common ports. With the correct profile set, click the “Scan” button. To start a quick scan, click the profile drop-down menu and select the “Quick” option. If you’re just looking to get a baseline and determine what ports may be open, try “Quick”. Usually, scanning ports is a long, painful process. After writing the IP address in, you’ll need to select the type of operation to use. To start a scan, type in the known IP address into the “target” section. Now that the Zenmap tool is open, it’s ready to scan ports. Open up a terminal and run the following command to launch the app with root privileges: sudo zenmap Without root access, key features will refuse to work. To start a scan, Zenmap must be running as root. In this article, we are scanning ports for security purposes. With it, it’s possible to scan for open ports on nearly any machine as long as you know the IP address.
#Zenmap topology install
Step 4: build and install the program./configure
#Zenmap topology code
Step 3: use the CD command to enter the source code folder. Step 2: extract the source code from the Tar archive.
#Zenmap topology download
Step 1: run wget to download the latest source-code of Zenmap. Alternatively, follow these instructions to build it from source. To install, search for “zenmap” and install it.
#Zenmap topology software
Zenmap may be in your distribution’s software sources. Once it is enabled, use the Zypper package manager to install it to the system. OpenSUSE distributes Zenmap via the “OSS all” software repository. sudo dnf install -y nmap-frontend OpenSUSE Open up a terminal and use the DNF packaging tool to install Zenmap. Instead, Fedora users looking to use the Zenmap tool will need to install nmap-frontend. sudo pacman -S nmap Fedoraįedora Linux doesn’t have a “Zenmap” package. Installing this package will also install Zenmap. Instead, Arch users looking to use the GUI frontend for Nmap will need to install the nmap package via Pacman. On Arch Linux, there isn’t an official “Zenmap” package in the software repositories. If you’re in need of a newer version of Zenmap than what is included with Debian Stable proper, check out Debian Backports. However, keep in mind that this version is out of date due to the nature of Debian.

Otherwise, use this command in terminal: sudo apt install zenmap Debianĭebian has a version of Zenmap that is available for easy installation via the included software sources. Open up “Ubuntu Software Center,” search for “Zenmap”, and select the “Install” button. On Ubuntu, users can quickly get the latest version of Zenmap working without much trouble as Canonical makes it available in the main software sources. To install it, open up a terminal and follow the instructions below depending on your OS of choice. The software is usually found in mainstream distribution’s package repositories. Many people in the security industry use it, and as a result, it is simple to install on most mainstream Linux operating systems. The program is by far the most well-known graphical front-end for Nmap on Linux. When it comes to port scanning, Zenmap is king. If you’re curious about that state of ports on your Linux PC, or other network devices on your network, you may want to scan open ports and close the ones you’re not using. Having ports like this open is a great way for intruders to gain unwanted access to your Linux PC. Leaving vulnerable networking ports open is dangerous, even with a steller, safe OS like Linux.
