Hi,

I am trying to interface a router to a cloud via bridged adapter or a loopback adapter but I am getting the error exactly like on the figure. Note: I have created bridge connection between added MSLoopback and my wireless adapter. Please help as I am stucked here forever.

The winpcap service (NPF service) cannot find your network adapter. Try the following by starting cmd.exe as an administrator:

network_device_list

Please post the output of network-device-list.cmd.

ERROR: The system was unable to find the specified registry key or value.

This isn't right. What is your Windows version? Do you have any security suite software or similar running?

Robert-xiaoqiang commented 5 years ago

Hi! The OS is Windows 10, and GNS3 is 2.9.1. I have installed both Win10Pcap and NPcap. Because the Win10Pcap isn't identified by GNS3. I don't know other security suit software running. Thanks!

delnomad commented 5 years ago

Hey Robert,

I had exactly the same problem. To solve it:

  1. Uninstall Win10Pcap and GNS3.
  2. Install Winpcap 4.1.3 (be sure that there were no errors with C:\Windows\System32\drivers\npf.sys during installation).
  3. Install GNS3 (without Win10Pcap) and configure VMware vmnets interfaces

Let me know if it helps, -Chris

grossmj commented 5 years ago

@merwina @Robert-xiaoqiang we recommend to only install Winpcap 4.1.3 only at the moment. Please let us know if this work after you install winpcap and a reboot.

Robert-xiaoqiang commented 5 years ago

Thanks! @grossmj @merwina I solved the problem by using GNS VM. Connecting cloud device with VMware network adapter works in my case. I gave up connecting it with loopback. -Chris
