3 Software Installation
3.5.2 macOS (app bundle)
The following is useful if you want to install the extcap globally, or on older Wireshark versions, assuming
”nose” is already installed via Homebrew:
ln -s `which nose` /Applications/Wireshark.app/Contents/MacOS/extcap/nose
The
/Applications/Wireshark/
part of the path can be different, depending on where exactly Wireshark
is installed. Check the Wireshark about dialog (”Folders” tab) if you are unsure.
You need to start Wireshark at least once before you run the above command. Otherwise,
macOS may show a security warning, and it won’t work.
3.5.3 Windows
Since Windows does not support symlinks properly, it is recommended to create a .bat file in the Wire-
shark extcap sub-directory. The installer creates a file named
intona-ethernet-debugger.bat
with the
following contents (assuming default paths and English locale):
"C:\Program Files\Intona\Ethernet Debugger\nose.exe" "%*"
This ”redirects” all invocations to the actual installation location.
The user-specific path is
C:\Users\USERNAME\AppData\Roaming\Wireshark\extcap\
. Replace
USERNAME
with the actual username. You may need to create the last component of the path. The installer does not
try to use this.
Updating Wireshark tends to remove and recreate the Wireshark installation directory. This
will also remove the
intona-ethernet-debugger.bat
file created by the Ethernet Debug-
ger installer. You could run the installer again to fix this. Manually moving the .bat to the
Wireshark user-specific configuration path mentioned above avoids this.
3.6 Firmware Update
Firmware updates may be required to get new features and to apply bug fixes. Normally they are not
necessary. Applying such an update must be done explicitly. The update process rewrites the device’s
flash memory, and should not be interrupted. Make sure the device is connected via USB 3.0, as the
update will take a long time with USB 2.x. Firmware downloads are available here
.
3.6.1 Unix-like
Plug in the device, and ensure it’s using USB 3.0 (main LED is blue). Then run the following command on
the terminal:
nose --firmware-update Downloads/firmware.dat
Where
Downloads/firmware.dat
is the path to the firmware binary you downloaded.
If the firmware file is accepted, and the device is accessible, something like this will appear:
