Question

How I know all IP on my LAN Wireless using ubuntu 14.04

Answer 1

WiFi networks

You can use the command nmcli to display all the connections that are available to your system from the command line.

Example

$ nmcli d wifi list
SSID                              BSSID               MODE             FREQ       RATE       SIGNAL   SECURITY   ACTIVE  
'WIFINET1'                        00:12:34:56:78:1F   Infrastructure   2462 MHz   54 MB/s    71       WPA2       yes     
'HP-Print-74-Photosmart 6520'     12:34:56:78:90:74   Infrastructure   2437 MHz   54 MB/s    25       WPA2       no      

IP addresses of systems on WiFi

If on the otherhand you'd like to get the IP addresses of all the systems that are accessible to you on your WiFi network you can use the following command fing. You can download fing from overlooksoft.com, and install it.

Once installed you'll need to determine your WiFi network's IP address. On my Fedora 19 system, the WiFi interface is called wlp3s0. This command will give you the IP address.

$ ip addr list wlp3s0 |grep "inet " |cut -d' ' -f6|cut -d/ -f1

Example

$ ip addr list wlp3s0 |grep "inet " |cut -d' ' -f6|cut -d/ -f1
10.9.8.0/24

With the IP you can run the following fing command:

$ sudo fing 10.9.8.0/24
