Was bedeutet es, ob das Netzwerkgerät Loopback ist?

1424

Bedeutet das, dass das Loopback-Gerät die Anfrage wie behandelt ping localhost?

Wenn ja, sollte es mindestens ein Gerät geben, bei dem es sich um Loopback handelt, aber anscheinend ist keines meiner beiden Netzwerkgeräte Loopback:

rpcap://\Device\NPF_ Description: Network adapter 'Intel(R) PRO/Wireless 2200BG Network Conne ction (Microsoft's Packet Scheduler) ' on local host Loopback: no  rpcap://\Device\NPF_ Description: Network adapter 'Realtek RTL8169/8110 Family Gigabit Ethern et NIC (Microsoft's Packet Scheduler) ' on local host Loopback: no 

Kann jemand das alles klären?

None of your physical devices will be a loopback device.

"In TCP/IP a loopback device is a virtual network interface implemented in software only and not connected to any hardware, but which is fully integrated into the computer system's internal network infrastructure. Any traffic that a computer program sends to the loopback interface is immediately received on the same interface."

I'm not sure, but I have understood that loopback device is not a real device, but a virtual one. It's purpose is to be a fake device that can quickly transfer signals, streams, etc. from a machine to itself.
