Error: Error: No devices to listen

[AlSa-Her]

Hello,
i finally got the node to install. Nonetheless, I now get an error when having the node in a flow and deploying. Once deployed, the node immediately sends the error:
Error: Error: No devices to listen
even though I did add the right MAC Adress (copied out of the findbutton-skript and double checked with my router settings-page).
What I noticed is, that I do get four
node_pcap: EthernetFrame() - Don't know how to decode ethertype 34958
messages in the bin/findbutton skript every time i press the button before the actual mac-address is displayed (It does find the right mac address without problems though!).

My configuration:
Raspberry Pi Zero W running DietPi
Node.js v6.10.0
Node-Red v0.17.5
npm v5.5.1

Thanks in advance!

Hey,

I got it to work for me few weeks ago.
The problem was the "capabilities" of the program "node". As explained in this link (german, also mentioned in issue #2), this can be fixed using the setcap tool.

The exact code which fixed the problem for me was:
sudo setcap 'cap_net_raw,cap_net_admin+eip' $(readlink -f $(which node))

Hope this helps,
cheers!
