I am confused by differences in extcap between the CLI and the GUI. By default (in 3.0.0 on both Windows, Macos), extcap tools are presented as interfaces on the capture page. <Screen Shot 2019-03-23 at 8.11.37 PM.png>
And in TShark, they're presented in the list of devices printed by the -D flag, because it can capture on them.
Questions 1. In the Wireshark GUI, if you go to About > Plugins, you can see the extcap directories.
By which you presumably mean "you can see the full path of all extcap *executables*. If you want to see the extcap *directory*, you want About > Folders.
Is it possible to get the extcap directory using a CLI command like tshark,
tshark -G folders, which is the equivalent of About > Folders. There is no way to list the full paths of extcap executables from the command line; tshark -G plugins, which looks as if it's *intended* to be the equivalent of About > Folders, lists only run-time-loadable-object and Lua plugins, not extcap plugins.
2. Why does dumpcap -D not show the same interfaces that the GUI does?
Either because 1) there's a bug or 2) it can't capture on extcap devices, so it shouldn't report them. From a quick test, it appears that 2) is the case here. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
