I started an update on another machine, it’s asking to install that same version. I could cancel out and install npcap manually, but since the Ethereal days I’ve always let the installer update Winpcap/npcap.

Npcap installer is supposed to properly uninstall WinPcap (at least I did not face any issue), but maybe there are some corner cases. Or you face a Npcap issue specific to your machine.

 

What version should I be using?

Npcap 0.99-r9 was the latest available when we released Wireshark. Npcap 0.991 is out since a few hours only and will likely be the version bundled in the next Wireshark update (unless Nmap folks release another version in the meantime).

If you still face an issue after installing version 0.991, I advise you to report your problem here for a better support: https://github.com/nmap/nmap/issues

Best regards,

Pascal.

Hi Graham and David,

As you had WinPcap before, there might be conflicts.  I've always manually uninstalled WinPcap before upgrading to npcap.

 

Suggestions at this point are:

1. Reboot.
2. Manually uninstall any existing WinPcap and npcap instances, then manually reinstall npcap[1].

[1] npcap doesn't seem to make the previous releases accessible, and there has been very little, if any, Wireshark testing with the current release.  It's only an hour old!

 

You can find all the versions here: https://nmap.org/npcap/dist

 

Pascal.

I installed it along with Wireshark and didn’t (intentionally) change any options. I see that there’s a different version on the npcap site, but I’ll wait to hear back before doing anything.

That shows that you're using npcap (with Npcap version 0.99-r9) as a capture library.

 

Did you change install npcap with the Wireshark installer or separately?  Did you change any of the npcap options in the installer?

What is the contents of the Wireshark -> Help -> About Wireshark -> Wireshark dialog?  You can highlight the text and copy it and paste it into your reply.  You could also use the output of "tshark --version".

Hi Devs,

 

I’m using Version 3.0.0 (v3.0.0-0-g937e33de) on Windows 10 Pro 64-bit 1903 (build 18356.1), and there are no interfaces at all showing when I start Wireshark. WinDump -D shows:

 

1.\Device\NPF_{C0E23443-4215-4E51-8016-633F44FC063E} (Realtek PCIe GBE Family Controller)

2.\Device\NPF_{AA3C112A-73F5-420E-8078-6C4B7CDA69C5} (Microsoft)

7.\Device\NPF_{6562DFC2-4BF3-4007-BDC4-7A2249032205} (Microsoft)

 

If I run windump on interface 3 I see traffic.

 

I know that 3.0 worked after I initially installed it, however I don’t know if it worked after the first reboot after that, and I have subsequently received Windows 10 updates (I’m on the Insider Slow ring). I’ve rebooted several times with no change.

 

For what it’s worth, Microsoft Netmon does display the interfaces and capture traffic, though I realize that’s not via npcap.

 

I’d appreciate any help.

 

Thanks,

 

David
