It will periodically scan for new devices on the network and will notify you if there is a new device. It’s called Nutty (last updated in 2019). So, now we have a GUI tool that does this task. I suggested including a periodic device scan feature in this tool and the developer readily agreed. Then I came across a new network monitoring tool being developed for elementary OS. When I first wrote this article, there was no GUI tool for this task. Method 2: Using GUI tool to find devices connected to network If you are wondering about why I used 24 in the above command, you should know a little about CIDR notation. The router itself, my laptop, and my Android smartphone. Nmap scan report for android-95b23f67te05e1c8 (192.168.1.93)Īs you can see that there are three devices connected to my network. Nmap scan report for takshak-bambi (192.168.1.91) Nmap scan report for neufbox (192.168.1.1) Use the nmap command in the following way: sudo nmap -sn 192.168.1.0/24 It is advisable to use root privileges while scanning the network for more accurate information. Step 3: Scan to find devices connected to your network You may also use ip a command to know your IP address in Ubuntu and other Linux distributions.Īt the same time, I’ll recommend you read about basic Linux networking commands for more information. The important things are highlighted in bold. TX packets:2013773 errors:0 dropped:0 overruns:0 carrier:0 RX packets:2135051 errors:0 dropped:0 overruns:0 frame:0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Wlan0 Link encap:Ethernet HWaddr 70:f1:a1:c2:f2:e9 Look for wlan0 if you are using wifi or eth0 if you are using Ethernet.

Use the ifconfig command to find the IP address in Linux. Now we need to know the IP address range of the network. It should be in the official software repository. You can easily install it in other Linux distributions as well. Use the following command to install nmap in Ubuntu based Linux distributions: Nmap is one of the most popular network scanning tool in Linux. The nmap command can be used to scan your network and see who is on your network. Method 1: Use Linux command line to find devices on the network It allows them to pester me at home more easily, so I'm well aware of that device.If you don’t remember the router password or you don’t want to go that way, here’s what else you could do.

The Avaya device is a Voice Over IP phone that provides me with an extension on the telephone system at head office. There's a couple of devices listed as manufactured by Dell. The only Samsung device I have is a laser printer, so that narrows that one down. The Amazon Technologies device will be my Echo Dot. Raspberry Pi Foundation is self-explanatory. What some of these devices are is clear to me. These are the ones we need to investigate further. When you look through your results, you will likely see devices that you recognize. Or, as we shall see, we have what nmap has reported as the manufacturer, to the best of its ability. We know the manufacturer for some of them. There are 15 devices switched on and connected to the network. We've established a list of the connected network devices, so we know how many of them there are.

The parameter '192.168.4.0/24' translates as 'start at IP address 192.168.4.0 and work right through all IP addresses up to and including 192.168.4.255'. The '/24' tells nmap to scan the entire range of this network. That is the first possible IPAddress on this network. The IP address we're going to use is the one we obtained using the ip command earlier, but the final number is set to zero. Don't be surprised when nothing visible happens for a minute or so. It does all of its probing and reconnaissance work first and then presents its findings once the first phase is complete. Of course, the more devices you have on the network, the longer it will take. It will do a lightweight, quick scan.Įven so, it can take a little time for nmap to run. This tells nmap to not probe the ports on the devices for now. We're going to use the -sn (scan no port) option. It can deduce a lot about the device it is probing by judging and interpreting the type of responses it gets. It works by sending various network messages to the IP addresses in the range we're going to provide it with it.
