ping (networking utility)
Aug 23, · Ping is a network diagnostic tool used primarily to test the connectivity between two nodes or devices. To ping a destination node, an Internet Control Message Protocol (ICMP) echo request packet is sent to that node. Jun 21, · The ping command sends packets of data to a specific IP address on a network, and then lets you know how long it took to transmit that data and get a response. It’s a handy tool that you can use to quickly test various points of your usadatingescort.com: Brady Gavin.
Ping is a network diagnostic tool used primarily to test the connectivity between two nodes or devices. If a connection is available, the destination node responds with an echo reply. Ping calculates the round-trip time of the data packet's route from its source to the destination and back, and determines whether any packets were lost during the trip.
The network ping tool was created by Mike Muuss in It contains almost one thousand lines of code and has become what is ping in network standard packaged tool for various network applications and operating systems.
The ping utility works by generating an ICMP data unit that is then encapsulated into IP datagrams and transmitted over the network. After receiving the echo request, the destination node copies its payload, destroys the original packet and generates an echo reply with the same payload it received.
Round-trip time is calculated by noting the local time of the source node clock when the IP datagram leaves the source node, then subtracting that time from the time at which the echo reply arrives.
Depending on the operating system, ping utility output varies. However, almost all ping outputs display the following:. The ping tool displays various error messages if a round trip is not completed successfully.

They include the following: TTL Expired in Transit: Determines the maximum amount of time an IP packet may live over the network before being discarded if it has not reached its destination. To address this error, try to increase TTL value by using the ping -i switch. Destination Host Unreachable: Indicates that the destination node is down or is not operating on the network.
It may even occur due to the non-existence of a local or remote route for the destination host. To address this error, modify the local route table or switch the node on. Request Timed Out: Indicates that the ping command timed out because there was no reply from the host.
It indicates that no echo reply messages were received due to network traffic, failure of Address Resolution Protocol ARP request packet filtering or a router error. Increasing the wait time using the ping —w switch may address this problem.
Unknown Host: Indicates that the IP address or the host name does not exist in the network how to take viagra 100mg that the destination host name cannot be resolved.

How to Use Ping
Mar 26, · But what is a “ping” really? What does it mean in the computing world, and why does it have such an odd name? Where Did the Name Come From? There are a few theories that “ping” is actually an acronym, and some say it stands for “Packet Internet or Inter-Network Groper.” But there’s nothing really substantial to say it stands for anything. Oct 07, · Ping 2. In networked computer gaming, ping is a measurement of the latency of the game's network connection to the server.
What does it mean in the computing world, and why does it have such an odd name? What everyone does agree on is that its name comes from the sound that sonar makes when it detects another vessel. This is a good term, as it gives a brief explanation of how pinging works in the computing world! Second, if the target is able to communicate, it measures how long it would take to receive a reply. Using ping to check the status of a server is very handy when trying to solve a network problem.
Networks are typically made up of a lot of different servers. If one of them goes down or is acting slow, it can prevent you from connecting to the server you want to access. Even worse, there will be very little feedback on which server, exactly, is the one causing the issues! By pinging from your computer to the target server, you can see the steps your communication takes as it makes its journey.
This means you can diagnose what step of the journey has gone bad and can fix the problem accordingly. If the server is already talking to your computer just fine, a ping test can tell you how fast your connection is.
This is particularly handy in video games where every player is talking to a central server. If the ping is too high, your computer takes a while to send and receive information from the server. Image Credit: Dunk. Where Did the Name Come From? Is this article useful? Yes No.
