Wireshark · Wireshark-dev: Re: [Wireshark-dev] Npcap 0.04 call for test

[Yang Luo <hsluoyb@xxxxxxxxx>]

Hi Pascal,

Sometimes network is not working because Npcap is a optional filter driver and can cause network to be unavailable for up to 90 seconds (refers to: https://support.microsoft.com/en-us/kb/2019184), so this is expected, I think adding a hint about this is a good idea, and moreover if someone could reproduce this, it would be easier to have a fix about it.

Cheers,

Yang

Hi Pascal,

Thanks for this bug. This bug is because loopback flag in Npcap driver isn't set when the driver is paused and restarted (occurs when system resumes from sleep). I have fixed it.

Try lastest installer at:

https://svn.nmap.org/nmap-exp/yang/NPcap-LWF/npcap-nmap-0.04-r9.exe

Hi Yang,

thanks for the updated driver. I just tested it on the Windows 7 x64 laptop that was having BSoD beginning of August and I can happily tell you that:

- it does not crash anymore and WiFi is working fine with Npcap installed

- loopback interface is still working after a suspend / resume

Thanks for your work and congratulation for your GSoC. I guess (hope?) it was considered as being successful :)

 

Yes, I have completed the project successfully, and lots of test work from Wireshark has helped me so much, thanks for all your work too:)

 

Hi Yang,

a small glitch I just noticed: you forgot to update the string used by Wireshark to get Ncap version (as seen in About Wireshark dialog box:). It reports "Npcap version 0.04 (packet.dll version 1.00), based on WinPcap version 4.1.3 (packet.dll version 4.1.0.3001), based on libpcap version 1.0 branch 1_0_rel0b (20091008)".

This is because that wpcap.dll version string is not updated to 1.00, I have fixed it and improved the appearance of the installer. Try installer at:

https://svn.nmap.org/nmap-exp/yang/NPcap-LWF/npcap-nmap-1.00.exe

Thanks it looks fine now. The only minor thing I noticed is that I need to reboot my laptop after installing Npcap. Otherwise WiFi is not working anymore. I do not know whether this is expected or not, but there is no hint about this during the installation process.

Cheers,

Pascal.
