Dari milis tentangga : The loopback address is a special Internet Protocol (IP) address used to test the protocol stack on a host.
In Transmission Control Protocol/Internet Protocol (TCP/IP) networking, the loopback address is the special IP address 127.0.0.1. The loopback address can be used to test the protocol stack on a host even when the host is not connected to a network. For example, to test whether TCP/IP is installed and configured correctly on a machine running Microsoft Windows, type ping 127.0.0.1 at the command prompt. Alternately, you can type the command ping localhost to achieve the same result since the Hosts file on a Windows machine resolves the friendly name localhost into the IP address 172.0.0.1. Finally, you can even ping any legal IP address of the form 127.x.y.z to test your TCP/IP protocol stack. If this test produces an error, either your network interface card (NIC) is incorrectly configured or your protocol stack is corrupt. If the configuration looks correct, try removing and reinstalling TCP/IP on your machine to fix the problem. If that fails, try reinstalling the driver for your NIC or replacing the NIC Regards, Panji.M -- Berhenti langganan: [EMAIL PROTECTED] Arsip dan info: http://linux.or.id/milis.php
