ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It is available in a wide range of operating systems – including most embedded network administration software.
The IP MTU and Ethernet maximum frame size are configured separately. In Ethernet switch configuration, MTU may refer to Ethernet maximum frame size. In Ethernet-based routers, MTU normally refers to the IP MTU. If jumbo frames are allowed in a network, the IP MTU should also be adjusted upwards to take advantage of this.
This type of attack has an amplification factor of 1, which means: just a single Smurf per ping. When the target is a unicast address and the destination is the broadcast address of the target's network, then all hosts in the network will receive an echo request. In return they will each reply to the target, so the target is swamped with n Smurfs.
This "ping" time is measured in milliseconds — and the lower the latency, the better, because a high latency means there's more lag in your network connection.
Bufferbloat is the undesirable latency that comes from a router or other network equipment buffering too many data packets.Bufferbloat can also cause packet delay variation (also known as jitter), as well as reduce the overall network throughput.
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 replies.
As promiscuous mode can be used in a malicious way to capture private data in transit on a network, computer security professionals might be interested in detecting network devices that are in promiscuous mode. In promiscuous mode, some software might send responses to frames even though they were addressed to another machine.
RTT is a measure of the amount of time taken for an entire message to be sent to a destination and for a reply to be sent back to the sender. The time to send the message to the destination in its entirety is known as the network latency, and thus RTT is twice the latency in the network plus a processing delay at the destination. The other ...
