      @jthirasilpa it matches the IP address with the scanned Mac addresses.
      If not in the Mac addresses it is not shown.

      In debug mode I get a big blast of the Mac address info displayed every time there is a scan

          This is one of the devices from the config.js

          { ipAddress: "192.168.1.11", name: "Champagne", icon: "server"}
          
          MMM-NetworkScanner received a notification: IP_ADDRESS 
          Object { ipAddress: "192.168.1.11", name: "Champagne", icon: "server", color: "#ffffff", showOffline: true, online: true }
          

          This is from the console:

          MMM-NetworkScanner.js:70:30
          MMM-NetworkScanner IP_ADDRESS device:  
          Array [ "Champagne", true ]
          MMM-NetworkScanner.js:80:31
          MMM-NetworkScanner is updating device status. 
          Array [ "Champagne", true ]
          MMM-NetworkScanner.js:284:31
          MMM-NetworkScanner Champagne is online
          

          Strangely when I run sudo arp -scan -l, this device doesn’t appear. But doesn’t the information from the console suggest that it should be displayed?

          Conversely, the arp scan does find 192.168.1.15, but console displays this:

          MMM-NetworkScanner received a notification: IP_ADDRESS 
          Object { ipAddress: "192.168.1.15", name: "Millie", icon: "server", color: "#ffffff", showOffline: true, online: false }
          MMM-NetworkScanner.js:70:30
          MMM-NetworkScanner IP_ADDRESS device:  
          Array [ "Millie", false ]
          MMM-NetworkScanner.js:80:31
          MMM-NetworkScanner is updating device status. 
          Array [ "Millie", false ]
          

          I would think that one of these would be displayed on the MM.

          Any further thoughts? Thanks.

            @jthirasilpa are those wireless? The arp scan only did Ethernet connected devices

              Those devices are ethernet connected. Also, I was just checking the logs and there are a lot of ip addresses and:

              0|mm       | [20:52:38.389] [LOG]    MMM-NetworkScanner is performing arp-scan
              0|mm       | [20:52:38.419] [LOG]    MMM-NetworkScanner is performing ip address scan
              

              but no MAC addresses - which you seem to have in your logs.

                After a complete reinstall of MM, I finally managed to resolve this. After reinstalling the original NetworkScanner module and using macaddresses to add to the config.js, I kept getting the “sudo requires your password” message. I went through node_helper.js and the only command that appears to require sudo is arp-scan. So I amended sudoers to allow sudo arp-scan without password using:

                sudo visudo
                

                and then adding:

                 # Allow arp-scan without sudo
                username ALL=(ALL) NOPASSWD: /usr/sbin/arp-scan
                

                This allows sudo arp-scan to run without a password, while maintaining password requirements for other sudo commands.

                Many thanks to Sam et. al. for input on this issue.

                  @jthirasilpa cool. Thx for the update. Using the updated file w password support should have allowed without sudoers

                    Hello,
                    i want to use this Module, but i’ve a iphone that is after some time offline when the screen is off. I have a perl script that check into my fritzbox (router) if the iphone connected to the fritzbox.

                    how can i add the perl script to mmm-networkscanner?

                    var arp = sudo([‘arp-scan’, ‘-q’, arpHosts]);

                    like var arp = sudo([‘perlscript.pl’]); ??

                    Thanks!!
