disable ping to my VPS hosting server

[Emotion]

There are a lot of programs that can scan hosts. I would like to ask how to disable ping to my VPS hosting server?

[Mr.Bond]

To disable ping request just run the following firewall command:
iptable -A INPUT -p ICMP --icmp-type echo-request - j DROP
If you wish can read something about psad, it's little complicated but you can check it if you have more free time.
Port Scan Attack Detector (psad) is a collection of three lightweight system daemons (two main daemons and one helper daemon) that run on Linux machines and analyze iptables log messages to detect port scans and other suspicious traffic.
