Is it possible to show wireless clients IP addresses connected to a RPI Hotspot?

[HypnoToad]

I've followed the guide here:

https://www.raspberrypi.org/documentati ... s-point.md

to create a wireless access point with internet access, and it's been working well for around 2 weeks now.

I'd like to the able to see the IP addresses of the devices connected to the hotspot as I need to update the firmware on 1 of the devices using a webinterface.

Is this possible? If so how?

I can find the MAC addresses of connected devices using the following command:

Code: Select all

systemctl status hostapd

and it shows a list like this:

Jul 21 17:07:50 pixx hostapd[725]: wlan0: STA b4:xx:xx:xx:fb:65 WPA: group key handshake completed (RSN)

Is it possible to find the IP addresses somehow?

Thanks

If you're using dnsmasq then I think you should see all the leases in /var/lib/misc/dnsmasq.leases
That does not necessarily mean they are still connected.

With "hostapd_cli all_sta", you can retrieve the MAC address of all connected stations.
Normally the client will be in the arp table of the AP, you can match the MAC to an IP address or name this way.
You should wrap that in a script, here is an example in bash.
