Troubleshooting a Connection Using Ping

The ping command verifies a connection to a remote host by sending four (by default) ICMP echo packets to the host and listening for echo reply packets. The ping command waits for up to one second for each packet sent and prints the number of packets transmitted and received.

To test a connection, you can use the ping command with the following options:

· An IP address
· A host name
· A computer name

1. Choose Start, Programs, and then click MS-DOS Prompt.

2. Type - ping 216.211.97.2 ( K-Net DNS Server ) at the prompt. Check to see if you received four replies.

If you did not receive the replies, you can verify that TCP/IP has initialized on your computer.

Type - ping localhost.
Localhost is a reserved host name that maps to a reserved IP address (127.0.0.1) that represents your computer. When you type ping localhost, the messages are local to your computer; no packets are sent to the network. If pinging localhost is successful, you receive four replies from IP address 127.0.0.1. If the ping command is unsuccessful you will receive a message that says localhost is unknown. If this happens, verify that you installed TCP/IP, and that you restarted the computer after the installation.
