The only requirement to make it work in Linux is having Java installed, which is easy in most distributions. You'll be able to scan IP addresses to detect live hosts, and at the same time gather critical information about each one of them. It isn't command line-based, but GUI-based instead, letting you scan your network from a fancy visual interface. Angry IP ScannerĪngry IP Scanner is one of the most popular IP address scanner tools available. 6 02: 0f:b5: 22: 90: 9c ( Unknown)ĥ packets received by filter, 0 packets dropped by kernelĮnding arp- scan 1.9. Here's a quick example: ~] # arp-scan -interface=wlp2s0 -localnetġ92.168. This will let arp-scan scan the interface wlan0 you can replace that with your real interface name. If you're working with a wireless network, you can also specify the type of network to scan by using: arp-scan -interface=wlan0 3 02: 0f:b5: 95: 4e: 20 ( Unknown)Ĥ packets received by filter, 0 packets dropped by kernelĮnding arp- scan 1.9. Interface: wlp2s0, datalink type: EN10MB (Ethernet) To perform an IP scan with this IP scanner tool, you'll need to run the following command: arp-scan 192.168.1.0/24 Same for Debian/Ubuntu-based distros: apt-get install arp- scan Installing this tool in Red Hat-based systems merely requires you to run: yum install arp- scan Arp-scan is quite useful for discovering all hosts within a specific network, even those that are protected behind firewalls. The ARP Scan Tool is another great resource for creating a full IP address map of any network. If you wanna learn more about Nmap, start exploring our Nmap Cheat Sheet to find plenty of examples and other Nmap techniques. If you're using Ubuntu/Debian, then this should do the trick: apt-get install nmap Nmap can be installed in CentOS/RHEL and other Red Hat-based distros by using: yum install nmap Nmap done: 256 IP addresses ( 48 hosts up) scanned in 10.28 seconds Performing this same scan on an Internet-connected server can yield a lot of interesting results. This type of IP scanner feature is also called "ping sweep" or "ping scan". Nmap done: 256 IP addresses ( 5 hosts up) scanned in 8.50 secondsĪs you can see, no port scanning has taken place-instead we used Nmap to ping hosts and get a response from each one of them. MAC Address: 70: 77: 81: 76: 9A:EF (Hon Hai Precision Ind.) Here, we're going to skip all port scans, using an option called "skip port scan": nmap -sP 192.168.1.0/ 24 So let's use some Nmap commands and begin the process of discovering all the servers behind the network. What many people don't realize is that Nmap is the perfect tool for a network IP audit. We've written about Nmap before, back when we explored the best port scanners and showed how easy it is to scan any host when you're seeking critical information such as open ports, OS version, and other pertinent details. Nmap has been and will probably remain our favorite hacking tool for infosec research tasks, and that includes IP scanning as well. We can't put any other tool in the number 1 spot. Let's take a look at the top IP scanner tools used by system administrators, network engineers and penetration testers.
