MMM-NetworkScanner-loading...indefinitely

[sdetweil]

@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

Thanks - tried that. Got the following log:

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

Thanks - see error log below

[22:23:34.736] [ERROR] ReferenceError: options is not defined

but you added the 4 lines, right?

var options = {              
    cachePassword: true,
    prompt: 'Password, ???? '     // put your password where ???? are (notice the quotes around)
}

and then the updated line

 var arp = sudo(['arp-scan', '-q', arpHosts], options);    

[karsten13]

what is the result of sudo arp-scan -l running on your machine?

[sdetweil]

@jthirasilpa just do this… get my version of the module

cd ~/MagicMirror/modules
mv MMM-NetworkScanner MMM-NetworkScanner.original
git clone https://github.com/sdetweil/MMM-NetworkScanner
cd MMM-NetworkScanner
npm install
cd ~/MagicMirror/config
nano config.js

add the following line to the config section of the network scanner module

Password: '??????',    // where '?????' is you password in quotes, for example 'raspberry', note the trailing comma

ctrl-o at save the config.js
ctrl-x to exit nano

Restart your MM

Thanks Sam - tried your version of the module and modified the config.js accordingly. Still not quite working. Error logs as follows:

@jthirasilpa hm… can u show me show me these lines from node_helper.js

scanNetworkMAC: function() {
        this.log(this.name + " is performing arp-scan");

        var self = this;
        // Target hosts/network supplied in config or entire localnet
        var arpHosts = this.config.network || '-l';
				var options = {              
						cachePassword: true,
						prompt: 'Password,' + this.config.Password     // put your password where ???? are (notice the quotes around)
				}
        var arp = sudo(['arp-scan', '-q', arpHosts], options);

I tested here with three different addresses… some coming online later… worked, no errors…

Hi - it seems to function correctly - it returns the IP and MAC addresses of the various clients on the network.
