MMM-NetworkScanner

[AshDarko]

I do however get this from time to time…

MMM-NetworkScanner received SCAN_NETWORK
MMM-NetworkScanner is performing arp-scan
Whoops! There was an uncaught exception...
TypeError: Cannot read property 'network' of undefined
    at Class.scanNetworkMAC (/home/pi/MagicMirror/modules/MMM-NetworkScanner/node_helper.js:42:36)

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?

Any ideas?

Just changed it to “devices:” and now it works… god knows why i had “device”… i dont know if this is in some code somewhere haha

Glad you got it sorted.

I think all the documentation and code uses devices, but if you spot otherwise, please raise an issue.

Difficult to say without more information. If you are able to reproduce the error, please share more details.

There appears to be a bug in the OUI and IAB scripts for arp-scan. IEEE have changed the URL for both files (from the defaults listed)

They are now:

http://standards-oui.ieee.org/oui/oui.txt
http://standards-oui.ieee.org/iab/iab.txt

You can either edit the get-oui and get-iab perl scripts (which was my preference), or run the scripts with the above URL’s instead of the defaults.

Also, don’t forget to move the resulting TXT files to /usr/share/arp-scan (if you run the scan from anywhere other than that directory)

[ianperrin]

Thanks @Bob, I’ve updated the URLs in the ReadMe file

I’m trying to use MMM-NetworkScanner as a monitoring tool so I can see what device is down.

Is there a way to only show devices if they are off-line. I have got to many devices to show them all, so I’m not interested in the on-line devices.

Also I’m trying to get there some colour in . But nonmatter what I do, there is only white. What is wrong in my config?

module : “MMM-NetworkScanner”,
disabled : false,
position : “top_right”,
header : “Monitoring”,
config : {
showUnknown : false,
showLastSeen : false,
keepAlive : 180,
updateInterval : 60,
showLastSeenWhenOffline : true,
color : true,
coloredSymbolOnly : true,
devices : [
{ ipAddress: “10.0.0.200”, name: “Wifi-Meterkast”, icon: “wifi”, color: “#ff0000” },
{ ipAddress: “10.0.0.201”, name: “Wifi-Woonkamer”, icon: “wifi”, color: “#ff0000” },
{ ipAddress: “10.0.0.202”, name: “Wifi-Zolder”, icon: “wifi”, color: “#ff0000” },
{ ipAddress: “10.0.99.201”, name: “Wifi-Garage”, icon: “wifi”, color: “#ff0000” },
],
},

Unfortunately, there’s not currently an option to hide online devices via the config. Feel free to raise a issue suggesting this enhancement via GitHub or even a Pull Request :winking_face:

However, there may be a way to do it using css. Devices which are online should be rendered in a table row (tr) with the class of bright, whilst offline devices will have the class of dimmed.

I’m away from my mirror right now, so the example below may not be quite right, but try adding the following to the custom.css.

.MMM-NetworkScanner table tr.bright {
  display: none;
}

As I’m away from my mirror at the moment, I can’t test your config, however, there may be an issue with the new color functionality introduced following a recent pull request.

Until I get chance to look at it, then if you want to color the icons for all offline devices in the same color (e.g. red), then again try adding this to the custom.css file

.MMM-NetworkScanner table tr.dimmed td i {
  color: #f00;
}

To color online devices, change tr.dimmed to tr.bright
To color the text as well as the icon, remove the trailing td i

@ianperrin : Cool, The colors are working now and the part for only displaying Off-Line is also working.
Thanks guys.

@ianperrin I am able to reproduce quite often, but it is seemingly running normally?

i had several of these happen just now:

Hi,
ive installed network scanner and its working great, im looking to tweek it a bit and was hoping for a little help…

i have mmm-pages installed with 3 pages and what im hoping for is when the resident is home it displays page 1 and when resident is not home it displays page 3, hoping to add voice triggers later as page 2 is a fullscreen google traffic map, but thats later! i have to get this working first. i also have mmm-remote-control installed as i think i need this, im trying to figure what commands to put in where in this code snippet.

 	                occupiedCMD: {notification: 'REMOTE_ACTION', payload: {action: 'MONITORON'}},
            		vacantCMD  : {notification: 'REMOTE_ACTION', payload: {action: 'MONITOROFF'}},
 

as always your help is very much appreciated! :)

[banbutcher]

@banbutcher

            occupiedCMD: {notification: 'PAGE_CHANGED', payload:{payload:1}},
            vacantCMD  : {notification: 'PAGE_CHANGED', payload: {'payload':'2'}},

i think it something like this but cant figure it out! :/

[banbutcher]

Nailed it down…

            occupiedCMD: {notification: 'PAGE_CHANGED', payload: 2},
            vacantCMD  : {notification: 'PAGE_CHANGED', payload: 0},

happy days, now i can go to bed! :D

So i just installed this module. For some reason the name/devices does not get highlighted.

This is my code:

   {
        module: "MMM-NetworkScanner",
        position: "top_left",
        header: "Wie is er thuis?",
        config: {
            devices: [
                { macAddress: "xx:xx", name: "Dad", icon: "male"},
                { macAddress: "xx:xx", name: "Mum", icon: "female"},
                { macAddress: "xx:xx", name: "Son", icon: "male"},
                { macAddress: "xx:xx", name: "Daughter", icon: "female"}
            ],
            showUnknown: false
     },

Someone know why its not working?

Hi Guys !

I’ve added MMM-NetworkScanner to my MM and I’m not able to see the result as columns.

My code in the config.js :

{
        module: "MMM-NetworkScanner",
        position: "top_center",
        header: "E-Tak Network",
        config: {

Any idea ?
Many thanks for your time !

It’s installed (1st step of the README) …
All it’s OK but impossible to display the result in columns. It’s always like a list.
(And sometimes, some peripherals are not OK … per ex. my computer)
