Hi there, hope you can help… i have tried everything and cannot get this to work. I just receive the “NO DEVICES ONLINE” message…(been working on it for two days)

But as i was writing this message… and inserting my config code i noticed my config said “device:”

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

If others are having trouble or getting error messages… just double check that haha… oh man feel like an idiot…

I do however get this from time to time…

Any ideas?

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” },
],
},
