hi everyone,

just wanted to post here ans share what i just learned

did you know you can block ICMP incoming pings to your linux server

yes, you can, its easy all you have to do is edit this file:

/etc/sysctl.conf


next look for this line:
net.ipv4.icmp_echo_ignore_all

NOTE: if you dont find net.ipv4.icmp_echo_ignore_all then simply added to the last line

be sure the the value is equals to 1 - so make it look like this:

net.ipv4.icmp_echo_ignore_all = 1
