Ping Requests use ICMP protocols. This is enabled/disabled using sysctl values.
To Disable Ping:
echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all
To Enable Ping:
echo 0 > /proc/sys/net/ipv4/icmp_echo_ignore_all

Great! Thank you very much!
I always wanted to write in my site something like that. Can I take part of your post to my site?
Of course, I will add backlink?
Sincerely, Timur I. Alhimenkov
