Ping command on Linux

PING Command in Linux: PING is a shortened form of Packet Internet or Inter-Network Groper. The Ping Command is one of the most used utilities for identifying, troubleshooting and testing issues related to network connectivity. The Ping command takes input as the URL or IP address and sends a data packet with the message “PING” to the specified address and obtain a response from the host/server and this recorded time is called latency. Ping works by sending ICMP (Internet Control Message Protocol) echo request messages to a defined IP destination on the network and waits for the ICMP reply. Using this ping command, you can test if a host is reachable(active) on an IP network or not. In an Internet Protocol (IP) packet, Time-to-live (TTL) is a value that informs a network router whether or not the IP packet has been in the network too long and should be rejected. In general, the ping time is calculated in milliseconds. It is the round trip time for the packet to reach the host/server and for the return response to the sender. In this article, we will assist you to make use of ping command Linux effectively.
