MMM-NetworkScanner-loading...indefinitely



  • 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,
                                    keepAlive:  600,
                                    showLastSeen:  true,
                                    updateInterval:  30
                                    }
                    },
    
    pm2 logs mm gives the following output:

  • @jthirasilpa said in MMM-NetworkScanner-loading...indefinitely:

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

    what is sending this message?

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



  • 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

    sorry, take off the ‘;’ after the actual password
