Network
Detect all Raspberry Pi on local network
From [1].
sudo nmap -sP 192.168.1.0/24 | awk '/^Nmap/{ip=$NF}/B8:27:EB/{print ip}'
where 192.168.1.* will be your local network mask.
We can also simply look for string Raspberry since nmap correctly identifies pi mac address:
sudo nmap -sP 192.168.1.0/24 | grep -B2 Raspberry
where 192.168.1.* will be your local network mask.
- Raspberry in BRIDGE mode
- Methods above fail if Raspberry is setup to bridge wlan0-eth0 connections. In that case, the visible MAC address is the one of the wlan0 interface. It can be detected because the address will be reported twice:
sudo nmap -sP 172.19.2.0/23|sort|uniq -d
# Host is up (0.18s latency).
# MAC Address: 00:0F:13:05:46:C2 (Nisca) <-- MAC address of the Pi in bridge mode
# MAC Address: 80:86:F2:99:56:B5 (Intel Corporate)
- Now we can repeat the request above to get the IP address:
sudo nmap -sP 172.19.2.0/23 | awk '/^Nmap/{ip=$NF}/00:0F:13/{print ip}'
Setup Pi as WiFi HotSpot (router)
This setup the Pi has a WiFi access point (AP) in router mode (NAT).
