Run failed here "Error setting the capture mode for device"

Maybe a permissions issue with the user running it? 🤔

Maybe a permissions issue with the user running it? 🤔 Permissions have been configured 1、requireAdministrator (/level='requireAdministrator')

2、[ERROR: D:\workspace\github\PcapPlusPlus\Pcap++\src\WinPcapLiveDevice.cpp: pcpp::WinPcapLiveDevice::startCapture:29] Error setting the capture mode for device '\Device\NPF_{22642BEC-89C2-48C3-9FF2-9F4012299A2C}'

3、Just comment out these lines of code PcapPlusPlus\Pcap++\src\WinPcapLiveDevice.cpp

4、At present, it only supports capturing Ethernet messages. Can the subsequent messages support the wireguard protocol? thank you

@qq805005062 can you try to add pcap_geterr() to see what the error is?

if (pcap_setmode(m_PcapDescriptor, MODE_STAT) < 0)
{
    LOG_ERROR("Error setting the statistics mode for device '" << m_Name << "', error is: " << pcap_geterr(m_PcapDescriptor));
    return false;
}

If that works you can open a PR with this change, might be useful for others

@qq805005062 I googled this error and here are a few interesting threads I found:

https://github.com/odedshimon/BruteShark/issues/99

https://www.winpcap.org/pipermail/winpcap-users/2007-October/002137.html

It looks like this error comes from this part of WinPcap / Npcap / libpcap code: https://github.com/limhoff-r7/libpcap/blob/master/pcap-win32.c#L140-L148

Which actually call PacketSetMode() which is defined in Packet32: https://github.com/clemensg/pcap/blob/master/packetNtx/Dll/Packet32.c#L2590

Is the NIC you're trying to capture packets from a standard Ethernet device or is it a WiFi, USB or AirPcap interface?

[dylu6699]

Ethernet device interface is Broadband network interface， Hardware network card，Ethernet of windows 10，Just comment out these lines of code

to be honest, I don't know what's causing the error. It works fine on every Windows machine I used. Do you have another Windows machine with a different NIC to test with?

I'm closing the issue now, please reopen if still relevant
