ping (networking utility) pinging is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It is available for virtually all operating systems that have networking capability, including most embedded network administration software. Ping measures the round-trip time for ...
The related ping utility is implemented using the ICMP echo request and echo reply messages. ICMP uses the basic support of IP as if it were a higher-level protocol, however, ICMP is actually an integral part of IP. Although ICMP messages are contained within standard IP packets, ICMP messages are usually processed as a special case ...
PathPing is a utility introduced with Windows NT that combines ping and traceroute functionality. MTR is an enhanced version of ICMP traceroute available for Unix-like and Windows systems. The various implementations of traceroute all rely on ICMP Time Exceeded (type 11) packets being sent to the source.
Computer users can use a ping tool, which sends and receives ICMP Echo Request messages, to determine whether a given computer is connected to the network. You can configure Firewall to prevent or allow computer users to ping your computer. To configure your ICMP ping requests setting: 1.
The dual unicast form is comparable with a regular ping: an ICMP echo request is sent to the patsy (a single host), which sends a single ICMP echo reply (a Smurf) back to the target (the single host in the source address). This type of attack has an amplification factor of 1, which means: just a single Smurf per ping.
Technical details. ICMP tunneling works by injecting arbitrary data into an echo packet sent to a remote computer. The remote computer replies in the same manner, injecting an answer into another ICMP packet and sending it back. The client performs all communication using ICMP echo request packets, while the proxy uses echo reply packets.
Ping flood. A ping flood is a simple denial-of-service attack where the attacker overwhelms the victim with ICMP "echo request" ( ping) packets. [1] This is most effective by using the flood option of ping which sends ICMP packets as fast as possible without waiting for replies. Most implementations of ping require the user to be privileged in ...
Ping of death. A ping of death is a type of attack on a computer system that involves sending a malformed or otherwise malicious ping to a computer. [1] In this attack, a host sends hundreds of ping requests with a packet size that is large or illegal to another host to try to take it offline or to keep it preoccupied responding with ICMP Echo ...
