Disable ping on linux

By Robin | juli 19, 2007

Almost all people starting with linux want to know after a while how to stop ping to prevent floods, well here is the solutions:

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

Only one thing left to do, you also want to get this after a reboot, so put in /etc/sysctl.conf.:

net.ipv4.conf.icmp_echo_ignore_all = 1
