      Re: MMM-NetWorkScanner

      I have run config:check and indicates no issue with the config.js syntax, but cannot get the networkscanner module to load.

      Here is the code from config.js: (note there is a missing { that dropped off code below)

                              module:                 "MMM-NetworkScanner",
                              position:               "bottom_center",
                              header:                 "Devices Online",
                              config: {
                                      devices: [
                                      { ipAddress: "192.168.1.11", name: "ABC", icon: "server"},
                                      { ipAddress:  "192.168.1.17", name:  "DEF", icon:  "server"},
                                      { ipAddress:  "192.168.1.133", name: "GHI,", icon: "mobile" },
                                      ],
                                      showUnknown: false,
                                      showOffline:  true,

        sudo requires your password: [20:18:51.080]

        what is sending this message?

          Thanks.

          Whenever it shows up, it is contiguous to the MMM-NetworkScanner received CONFIG reading in the log. When this module is added, npm install adds the “sudo” dependency - I assume that this is what is sending the message, but do not know how to confirm?

            @jthirasilpa cool, thx

            edit the node_helper.js
            add the following line

            const sudo = require("sudo");
            sudo.setPassword('your-password');      // add this line, edit to use your password
            module.exports = NodeHelper.create({

              Thanks Sam - I made that modification in node_helper.js in the module’s directory with my password.

              I get the following errors from the logs:

                Maybe some progress?

                So I amended the insertion as follows:

                sudo.setPassword = ('your-password');      // add this line, edit to use your password
                

                Config loads, but NetworkScanner module still shows “loading…”

                Error logs as follows:

                  @jthirasilpa ok, had to read the sudo module code to find out where it was… cause when I searched I ended up in the wrong place…

                  remove the one line I had you add

                  do this

                  // add these 4 lines
                  var options = {              
                      cachePassword: true,
                      prompt: 'Password, ???? ';     // put your password where ???? are (notice the quotes around)
                  }
                          var arpHosts = this.config.network || '-l';
                          var arp = sudo(['arp-scan', '-q', arpHosts], options);   // change this line, to add ,options at the end
