The application allows you to respond to ICMP requests exponentially, constantly increasing the timeout between requests by 2 times until it reaches 1048576 msecs (17 minutes).

Just go mod tidy && go build .

Run commands from root:

1. Disable icmp reply from kernel: echo 1 | tee /proc/sys/net/ipv4/icmp_echo_ignore_all
2. Allow using raw sockets: echo 1 | tee /proc/sys/net/ipv4/ping_group_range
3. Allow rules in iptables:

   iptables -I OUTPUT -p icmp --icmp-type echo-reply -j ACCEPT
   iptables -I OUTPUT -p icmp --icmp-type echo-reply -j ACCEPT
   

4. Allow run binary from regular user: setcap cap_net_raw+ep icmp_exp

5. Put binary to /usr/local/bin/
6. Create /etc/systemd/system/icmp_exp.service
7. Put everything from icmp_exp.service
8. Change User/Group
9. Reload: systemctl daemon-reload
10. Run and enable autostart: systemctl start icmp_exp; systemctl enable icmp_exp
