MMM-NetworkScanner-loading...indefinitely

jthirasilpa

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]

jthirasilpa

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?

sdetweil

@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({

jthirasilpa

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:

jthirasilpa

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…”

@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

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

[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…

jthirasilpa

@karsten13
Hi - it seems to function correctly - it returns the IP and MAC addresses of the various clients on the network.

jthirasilpa

@sdetweil
I tried it both ways - but should the ‘password’ field in the helper file be filled in?

sdetweil

@jthirasilpa no… use the config.js

the reference to the options variable should be from line 47, not 42…

so, something is wrong with the code u have in node_helper.js

did u follow my steps above exactly?

jthirasilpa

Sorry I’m not being clear. I know that I need to modify the config.js (and have done so), but in line 45 of node_helper.js (as shown below) there is:

 prompt: 'Password,' + this.config.Password     // put your password where ???? are (notice the quotes around)

Should I leave this as is or fill in the password? That is where I have tried it both ways.

Code you asked for from node_helper.js:

    scanNetworkMAC: function() {
 38         this.log(this.name + " is performing arp-scan");
 39
 40         var self = this;
 41         // Target hosts/network supplied in config or entire localnet
 42         var arpHosts = this.config.network || '-l';
 43                                 var options = {
 44                                                 cachePassword: true,
 45                                                 prompt: 'Password,' + this.config.Password     // put your password where ???? are (notice the quotes around)
 46                                 }
 47         var arp = sudo(['arp-scan', '-q', arpHosts], options);

sdetweil

@jthirasilpa oh, i see I should have removed the comment… you do not need to change any code…

but the error does not match the code u are running now…

please do

pm2 stop 0
pm2 flush
pm2 start 0
pm2 logs

that error must have been from yesterday
