Ping can be used to test a connection from one server to another server.
How ping works
Ping (Packet Internet Groper), uses the ICMP (Internet Control Message Protocol) to send an echo request message. This elicits an ICMP echo response, and the time it takes to receive this response can be used to measure the strength of the connection.
