Install it with cargo install --git https://github.com/m-ou-se/pong
.
You either need to run it as root, or you need to disable your kernel's ping reply with sysctl net.ipv4.icmp_echo_ignore_all=1 net.ipv6.icmp.echo_ignore_all=1
and give this program cap_net_raw
capabilities with setcap cap_net_raw=ep ~/.cargo/bin/pong
.
