MMM-NetworkScanner help needed

Im sure because you have the firewall on, it won’t ping if thats the case. This is one of the reasons I want to do it by MAC address.

@slametps I think so too. I could not get it to work with MAC addresses. Assigning static IP addresses is the only way I could get it to work, and even that was not perfect, as it would not show my desktop as active , even with a static ip address

Unfortunately, mine was not working, neither MAC nor IP. :sob:
While I tracing the execution through console log, the problem is in here:

...
payload.forEach(function (item) {
                var device = self.getDeviceByMacAddress(item); // device is null, although self.getDeviceByMacAddress() return not null. still no idea.
                console.log("devices: " + device);
                if (device) {
                    device.online = true;
                    device.lastSeen = moment();
                    self.networkDevices.push(device);
                }
            });

in this context self has no meaning - add var self = this; to the top of the function or replace self with this

self is already defined in the original complete code. the original author @ianperrin will take a look into the latest code (v0.0.2, I presume).
@Mykle1 : For now, I downloaded the previous version (tags v0.0.1 before the official bugs free the new version v0.0.2 fixed/released), and work like a charm.

git clone --tags v0.0.1 https://github.com/ianperrin/MMM-NetworkScanner.git

I just fresh cloned the (new) latest version (rather than update/git pull), it is working flawlessly now. Thx to @ianperrin.

And easy question I hope you guys can help with – is this module active or passive?

For example, if I take my magic mirror to work to show it off, will this module activly send out network traffic to the network and trigger security alerts (getting me in big trouble)?

I’m hoping the answer is that it only looks for IP and Mac addresses listed in the configuration.

[slametps]

@FlatPepsi it is active since arp-scan will executed every updateInterval setting. Of course, it will trigger such a security alert if violate the security policy of your office. No, arp-scan will scan all available devices in the network.

@Mykle1 try to execute the following in shell:

arp-scan -l -q

Compare all the scanned MAC with your MAC device entries in MMM-NetworkScanner.

I have run the command sudo arp-scan -l -q and somehow find only devices that are in the LAN, but no device what is in the WIFI - so unfortunately no mobile. My MM always shows me only “NO DEVICE ONLINE”.

I proceeded as follows:

cd ~ /
sudo apt-get install arp-scan

cd ~ / MagicMirror / modules
git clone https://github.com/ianperrin/MMM-NetworkScanner.git
cd ~ / MagicMirror / modules / MMM-NetworkScanner
npm install

cd ~ / MagicMirror / config
nano config.js

              {
                        module: "MMM-NetworkScanner",
                        position: "bottom_right",
                        config: {
                                device: [
                                        { macAddress: "XX:XX:XX:XX:XX:XX", name: "I", icon: "mobile"},
                                ],
                        showUnknown: true,
                        }
                },

In my case, all the devices on LAN and 2.4 networks are found, while 5ghz network is not seen even through sudo arp-scan -l -q
