I connect my hotspot through ap-hotspot and I can see the notifications pop out displaying new device connected , device disconnected. (Because I want to learn about privileges for access to use or not use the hotspot.)

How can I list the device connected through terminal?


arp -a should return you a list of all connected devices.

    also arp -an is useful --- to avoid long delays trying to resolve IP addresses. – Rmano Dec 27 '14 at 11:38
  • arp does not update real time – Luis Jul 21 '16 at 7:59

If you want a more detailed list, I adapted this script for the ap-hotspot script that comes from webupd8:


# show_wifi_clients.sh
# Shows MAC, IP address and any hostname info for all connected wifi devices
# written for openwrt 12.09 Attitude Adjustment
# modified by romano@rgtti.com from http://wiki.openwrt.org/doc/faq/faq.wireless#how.to.get.a.list.of.connected.clients

echo    "# All connected wifi devices, with IP address,"
echo    "# hostname (if available), and MAC address."
printf  "# %-20s %-30s %-20s\n" "IP address" "lease name" "MAC address"
# list all wireless network interfaces 
# (for MAC80211 driver; see wiki article for alternative commands)
for interface in `iw dev | grep Interface | cut -f 2 -s -d" "`
  # for each interface, get mac addresses of connected stations/clients
  maclist=`iw dev $interface station dump | grep Station | cut -f 2 -s -d" "`
  # for each mac address in that list...
  for mac in $maclist
    # If a DHCP lease has been given out by dnsmasq,
    # save it.
    ip=`cat $leasefile | cut -f 2,3,4 -s -d" " | grep $mac | cut -f 2 -s -d" "`
    host=`cat $leasefile | cut -f 2,3,4 -s -d" " | grep $mac | cut -f 3 -s -d" "`
    # ... show the mac address:
    printf "  %-20s %-30s %-20s\n" "$ip" "$host" "$mac"

copy it in a file in your PATH --- for example ~/bin/show_wifi_clients, make it executable with chmod +x, and enjoy.

  • A nice an crazy script, thanks for sharing, :)... – George Udosen Jan 24 '17 at 20:15

    the variables in printf " %-20s %-30s %-20s\n" $ip $host $mac" must be double quoted to print correctly. Edited the answer likewise... – Magguu Jun 2 '19 at 9:10
  • @Magguu you're right, edit accepted. – Rmano Jun 2 '19 at 10:42

Show a list of devices: (replace <interface> with the interface name of your wifi interface)

iw dev <interface> station dump

If you don't know the name of your wifi interface, use this command to find out the interface name:

iw dev

  • While this answer is good in its current state, it could still be improved. Perhaps you can add some example output or otherwise explain more as to what this command does? – Kaz Wolfe May 21 '17 at 20:21

I connected my phone to the network and used the awesome Fing app to scan the clients connected :)

This one also gets the mac vendors of the devices and can also label the mac of your devices

requires python3.6

import subprocess
import re
import requests

# Store Mac address of all nodes here
saved = {
    'xx:xx:xx:xx:xx:xx': 'My laptop',

# Set wireless interface using ifconfig
interface = "wlp4s0"

mac_regex = re.compile(r'([a-zA-Z0-9]{2}:){5}[a-zA-Z0-9]{2}')

def parse_arp():
    arp_out = subprocess.check_output(f'arp -e -i {interface}', shell=True).decode('utf-8')
    if 'no match found' in arp_out:
        return None

    result = []
    for lines in arp_out.strip().split('\n'):
        line = lines.split()
        if interface in line and '(incomplete)' not in line:
            for element in line:
                # If its a mac addr
                if mac_regex.match(element):
                    result.append((line[0], element))
    return result

def get_mac_vendor(devices):
    num = 0
    for device in devices:
            url = f"http://api.macvendors.com/{device[1]}"
                vendor = requests.get(url).text
            except Exception as e:
                vendor = None

        except Exception as e:
            print("Error occured while getting mac vendor", e)

        num += 1
        print_device(device, num, vendor)

def print_device(device, num=0, vendor=None):
    device_name = saved[device[1]] if device[1] in saved else 'unrecognised !!'

    print(f'\n{num})', device_name,  '\nVendor:', vendor, '\nMac:', device[1], '\nIP: ',device[0])

if __name__ == '__main__':
    print('Retrieving connected devices ..')

    devices = parse_arp()

    if not devices:
        print('No devices found!')

        print('Retrieving mac vendors ..')

        except KeyboardInterrupt as e:
            num = 0
            for device in devices:
                num += 1
                print_device(device, num)
