Disabling ICMP (Ubuntu/Debain based systems)


Greetings,

Have been digging around a little here and there trying to find an answer for my question the last couple of weeks.

Can you disable ICMP (So that someone cannot ping your box) for a Ubuntu/Debain based system. Had no problems at all turning off ICMP for my Fedora box.

Are you using sysctl? In /etc/sysctl.conf you can add net.ipv4.icmp_echo_ignore_all = 1 and restart sysctl with sysctl -p
