PING is a network diagnostic tool that verifies connectivity to a particular system on the network.
PING sends one packet per second and prints one line of output for every response received. When PING terminates, it displays a brief summary of round-trip times and packet loss statistics. Then, ping hosts and gateways further and further away. Response times will vary depending on network load. LDAP is a tool that lets you query information repositories for information contained in their databases.
