@sdetweil
Thanks Sam - tried your version of the module and modified the config.js accordingly. Still not quite working. Error logs as follows:0|mm | at process._tickCallback (internal/process/next_tick.js:61:11) 0|mm | [09:41:25.508] [ERROR] ReferenceError: options is not defined 0|mm | at Class.scanNetworkMAC (/home/jojo/MagicMirror/modules/MMM-NetworkScanner/node_helper.js:42:54) 0|mm | at Class.socketNotificationReceived (/home/jojo/MagicMirror/modules/MMM-NetworkScanner/node_helper.js:29:18) 0|mm | at Socket.<anonymous> (/home/jojo/MagicMirror/js/node_helper.js:113:11) 0|mm | at Socket.emit (events.js:198:13) 0|mm | at /home/jojo/MagicMirror/node_modules/socket.io/lib/socket.js:528:12 0|mm | at process._tickCallback (internal/process/next_tick.js:61:11) 0|mm | [09:41:55.508] [ERROR] ReferenceError: options is not defined 0|mm | at Class.scanNetworkMAC (/home/jojo/MagicMirror/modules/MMM-NetworkScanner/node_helper.js:42:54) 0|mm | at Class.socketNotificationReceived (/home/jojo/MagicMirror/modules/MMM-NetworkScanner/node_helper.js:29:18) 0|mm | at Socket.<anonymous> (/home/jojo/MagicMirror/js/node_helper.js:113:11) 0|mm | at Socket.emit (events.js:198:13) 0|mm | at /home/jojo/MagicMirror/node_modules/socket.io/lib/socket.js:528:12 0|mm | at process._tickCallback (internal/process/next_tick.js:61:11) -
@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…
-
@karsten13
Hi - it seems to function correctly - it returns the IP and MAC addresses of the various clients on the network. -
@sdetweil
I tried it both ways - but should the ‘password’ field in the helper file be filled in? -
@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?
-
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); -
@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 logsthat error must have been from yesterday
-
Hmm
So with the password entered only in the config file, the error output still references line 42
var arpHosts = this.config.network || '-l';Error output:

@jthirasilpa said in MMM-NetworkScanner-loading...indefinitely:
0|mm | [19:37:36.956] [ERROR] TypeError: Cannot read property ‘network’ of undefined
0|mm | at Class.scanNetworkMAC (/home/jojo/MagicMirror/modules/MMM-NetworkScanner/node_helper.js:42:36)Ok, but not ‘options’…
now, to check, this system is case sensitive… so in config.js it MUST look like this, right?
keepAlive: 300, updateInterval: 5, Password: 'pi' // added password (note capital P) }using your password of course
-
That is how the config looks.
Still getting the node_helper line 42 error. Will park this for now. Thank you for spending so much time on this Sam - much appreciated. Will come back to this later in the week.
-
@jthirasilpa update the current code
cd ~MagicMirror/modules/MMM-NetworkScanner git pullthen you can shutdown and restart the MM app
there was a tiny timing gap where the config info is not yet set, when the helper is asked to scan the network…
let me know
-
Is it bad to have this?
pi@raspberrypi ~ % sudo -l|grep NOPASS (ALL) NOPASSWD: ALL pi@raspberrypi ~ %Edit: To expand further, I have MMM-NetworkScanner running. I do not need to supply a password when I run sudo and I don’t have a password stored in a config file.

Hi Sam - thanks I tried the update. Still getting the same error - from the log:[19:00:49.868] [ERROR] TypeError: Cannot read property 'network' of undefined at Class.scanNetworkMAC (/home/jojo/MagicMirror/modules/MMM-NetworkScanner/node_helper.js:42:36) at Class.socketNotificationReceived (/home/jojo/MagicMirror/modules/MMM-NetworkScanner/node_helper.js:30:18) at Socket.<anonymous> (/home/jojo/MagicMirror/js/node_helper.js:113:11) at Socket.emit (events.js:198:13) at /home/jojo/MagicMirror/node_modules/socket.io/lib/socket.js:528:12 at process._tickCallback (internal/process/next_tick.js:61:11) -
@jthirasilpa do another git pull from my repo… and try again

@jthirasilpa weird…
the trace shows, on a timer tick (in the modulename.js) the node+helper received a socket message (sendSocketNotification from modulename.js), and received in node_helper)
the notification is correct, and it starts to rescan the network…but, it has lost the config pointer for some reason…
weird…
please do another git pull
also add debug:true,
to the module config section
let me know
thanks

Thanks. Scan seems to find some devices, but does not display them on Mirror.

and it says it will scan all the addresses in the devices list, but millie isn’t pinged…
what else do you have in bottom_center? it can get pushed off screen pretty easily…
-
Thanks - I did change the config to add one device “JoJo” with an IpAddress and I changed “Millie” from IpAddress to MacAddress (I am guessing that is why it is not showing in the ping result - but am not sure). I did not make any other changes to the config (apart from adding the debug line). There is no other bottom_center module and it clearly displays Devices Online “Loading…”, so I don’t think it’s the case that entries are being pushed off the page.

@jthirasilpa do you have arp-scan installed?
Open a terminal window and type
sudo arp-scanIf not install it. Not part of module.
sudo apt-get install arp-scan
