![]() ![]() So let's say I want to check IPs from 192.168.1.1 to 192.168.1.10 then I will be using the following: nmap -sn 192.168.1.1-10 Ping sweep multiple hosts using the ending octet So if you want to check whether the IPs in a specific range are up or not, you can benefit from this method. ![]() ): nmap -sn 192.168.1.* Ping sweep multiple hosts by specifying the IP range To ping sweep the entire subnet, you can use the wildcard * replacing the last octet (the last part of your IP after the. Ping sweep the entire subnet with the nmap command Especially, when you are dealing with a stack of machines. Let's say I want to ping three IPs 192.168.1.1, 192.168.1.7 and 192.168.1.8 so I will be using the following: nmap -sn 192.168.1.1 192.168.1.7 192.168.1.8Īnd as you can see, all of the tree hosts are up!īut there are more (and better) ways to ping sweep hosts. The simplest way to ping sweep multiple hosts is to append them one by one as shown: nmap -sn Once you have it installed, all you have to do is use the nmap command with the -sn flag: nmap -sn target_IP/s If it throws an error saying Command 'nmap' not found, it can easily be installed with the following command:įor Ubuntu/Debian-based distros: sudo apt install nmapįor Fedora/RHEL base: sudo dnf install nmapįor Arch-based distros: sudo pacman -S nmap How to use ping sweep with the nmap command You can check whether you have it installed by checking the installed version: nmap -v Usually, nmap does not come pre-installed. So in this tutorial, I will share some practical examples of performing ping sweep using the nmap command. Sure, you can do the ping sweep with various tools but using the nmap command to perform ping sweep is one of the most flexible and widely used methods. This can be a lifesaver when looking at which devices are up from the stack of machines while troubleshooting. In my case I've created an executable with msfvenom and run it on a Windows 10 virtual machine, getting a reverse HTTPS meterpreter session back to a Kali Linux VM.Ping sweep is the ability to ping multiple devices at once. It doesn't matter how you established the session, either through an Excel macro or some other means. With increased adoption of IPv6, which relies heavily on ICMP, this may become the case more and more.įor this exercise we assume you have Metasploit Framework set up or you're using Kali Linux in a VM, and have established a Meterpreter session with at least one host in a network. ICMP echos ( ICMP type 8) and echo replies ( ICMP type 0) on the network don't raise questions in many environments, and inside many networks ICMP is allowed through firewalls because sysadmins want to be able to easily ping around while troubleshooting. While it would be great to port scan entire subnets, we need to hold off and remain low-key at first. IDS products have become very good at detecting port scans, and seeing those inside their networks put sysadmins on the alert (or at least they should). Port scans have a big role in network scanning and enumeration, but they are very noisy, and a blatant giveaway that network reconnaissance and enumeration is happening.
