192.168.0.98       raspberrypi.local

pingall -i wlan0 --dont-resolve

192.168.0.19
192.168.0.98

Installation

cargo install pingall

Details

Simultaneously ping all of the addresses on your subnets with a 1 second timeout, so we can gauge who is responsive on the network. tokio is used to make it all asynchronous (only 1 thread is used).

Raw Ping

The system ping command is used by default, as opening raw sockets in unix requires root permissions. To avoid using the ping command, you can use the --raw-socket flag, but this will require either sudo, or running

setcap cap_net_raw+ep $(which pingall)

to give this program permission.
