I'd just like to see who is connecting to my computers Access Point wifi.

I'm sharing Internet from Ethernet to wifi with a password, etc.

  • Strictly speaking, it's not ad hoc, it's an Access Point.

Run the following to list all connections on your Mac through all interfaces.

arp -a

To limit to a single interface, use:

arp -a -i en1
  • thanks! this is a cool command. It just displays MAC addresses though, correct? I guess I was hoping for a GUI that could display device names or something more robust, like an admin tool.

  • @pinhead It shows IP addresses and hostnames too, but yes, there's no 'admin tool' of such.
