Network Administration, troubleshooting from Linux #1 Ping

Linux has dozens of tools for network troubleshooting, among them the famous Ping, the preferred tool that comes to my mind for any kind of IP connectivity related issue. This post is to explain basic information for people who would like to know its usage.

Ping is a well know tool to test the IP connectivity of a host in a network. When we execute ping followed by the host name/IP it sends Echo packets to the target until we press the Ctrl+C, in Linux.
