Disable ping On Centos

Disable ping response Temporarily

To disable the PING response, login as root and type the following command

# echo 1 >/proc/sys/net/ipv4/icmp_echo_ignore_all

To reenable the PING response do this:

# echo 0 >/proc/sys/net/ipv4/icmp_echo_ignore_all


Disable ping response Permanently

Edit the /etc/sysctl.conf file and add the following line

net.ipv4.conf.icmp_echo_ignore_all = 1

Execute sysctl -p to enforce this setting immediately

# sysctl -p
