Getting client's MAC address on node.js

Is there a way to find client's mac address on Node.js? I have been searching about it and i found node-sigar project but it didn't works because it throws a "cannot find module ./build/Release/sigar" error.

The getmac module will do this. It calls out to the command line to get the system's network config info and then uses a regex to parse output to find the mac address. The system commands it uses are getmac (Windows) or ifconfig (other platforms).

Unless your code is running on the same LAN segment as the client, you cannot obtain the MAC address of a client. You'd need to likely shell out to a command line tool or native support to gain addresses on the local LAN segment.

For nodejs: https://npmjs.org/search?q=Arp

If you try to get remote clients' MAC addresses, you'll end up with the address of a router more than likely.
