-sL just lists the hosts, and attempt a reverse DNS.This is the first step to identify interesting hosts. That is, you look for the hosts actually listening within a broader range of addresses. Host discovery is the first thing you do with nmap. Doing a scan can take time, so you don’t want to scan for something you already know you won’t need. Knowing some options will allow you to quickly get the information you need. Covering all the options is way beyond the objectives of this article, yet we are going to see the most common options. You can detect IPS and IDS systems, detect the target operating system, and more. Here you will see that you have literally tons of options to play with. In case you omit the target, nmap will show the help. This will scan all hosts in that subnet, identify which ones are up, and the exposed ports on each. For example, try using 192.168.1.0/24 as target (if your home router offers that network). A common approach is to target an entire subnet, in CIDR notation. This is because we can target multiple hosts or even entire networks at the same time. In the last line, it tells us that one host is up. Nmap done: 1 IP address (1 host up) scanned in 78.17 secondsĪs you can see, this will tell you the destination IP as well as the opened ports with the service they expose. After all, you need to tell nmap what you want to scan! The official nmap community offers you a sample target website to scan:. By default, you only need to specify the target. Scan type and options are in square brackets because they are optional. In fact, the syntax for the command is just this: nmap This is especially true for basics scans. Nmap tutorial: scanning with nmap A first scanĭespite its immense power, using nmap is simple.
Mac users will find executable binaries in the same link of Windows users. If you want zenmap as well (as you should), go to the official website of nmap.
#ZENMAP TOPOLOGY INSTALL#
Depending on your Linux version, you can run sudo apt-get install nmap or yum install nmap.
#ZENMAP TOPOLOGY FREE#
Luckily, both nmap and zenmap are free and open source!įor Linux users, using your package manager is enough to get you running. Once you install them, you are ready to use nmap in the prompt, and you can search for ZenMap within your installed programs. These are the executables that will install both nmap and zenmap.

If you are a Microsoft Windows user, you can download the binaries from the official nmap website. ZenMap can actually visualize the topology of the network graphically, and you can click on each host to gather more information. However, its best enrichment to nmap is about the output. With zenmap, you can construct nmap queries easily, and run them from a graphical interface. ZenMap is a graphical interface to facilitate the use of nmap.

In this nmap tutorial, we will see how to use options of this command to better control the scan. In the terminal or prompt, you can use the nmap command to launch the scan. With this precious information, he can use targeted attacks and exploit known vulnerabilities. Knowing services, versions, and operating systems is essential for the attacker. If you are lucky, nmap will even detect the operating system of each device. Using advanced techniques, it can identify what services are running on each host and even their version. To start, we can reconstruct the topology, identifying all the devices in the network. As we will see later in this nmap tutorial, you can use this tool to have a clear picture of the network. In fact, nmap is a tool that allows you to create a detailed map of a network. Nmap stands for “network mapper”, and this is pretty explanatory. In this nmap tutorial, we will see how to use nmap and its visual companion, zenmap. Even if you don’t want to do penetration testing, you should know how to use this tool. Several tools allow you to perform reconnaissance, but the most famous is nmap.
This aims to understand how the system works, and what are possible vulnerabilities. Yet, all the attacks starts from the same point: reconnaissance. Preparing attacks to systems and networks is complex.
