I have a TP-LINK WiFi router which shows lan IP addresses and computer mac addresses under Device Info > ARP. I am interested to read this info from my computer (Ubuntu 12.04) connected to the same network. Is there an Ubuntu command for it which can query IP/MAC list from router and show in terminal?
If there isn't any command. Is there a hit and test mechanism which I can use to collect lan IP addresses? What I would do is select IP address range 192.168.1.2 to 192.168.1.255 and ping it and see who replies. This will be very specific because I know all IP addresses on my networks are of class C. Do you know anything better than Ping?
