![]() ![]() ![]() The easiest way to do this is to select Start WinPcap service 'NPF' at startup in the Wireshark installer. Start the NPF driver automatically at system start There are three possible solutions to start Wireshark with the privilege to capture:ĭisadvantage: It's very unsecure running Wireshark this way as every possible Wireshark exploit will be running with the administrator account being able to compromise the whole system. Please note that this is not a limitation of the Wireshark implementation, but of the underlying WinPcap driver see this note in the WinPcap FAQ. It might not be desirable that any local user can also capture from the network while the driver is loaded, but this can't be currently circumvented. Note: Simply stopping Wireshark won't stop the WinPcap driver! Once the driver is loaded, every local user can capture from it until it's stopped again. The WinPcap driver (called NPF) is loaded by Wireshark when it starts to capture live data. If you are running inside a virtual machine, make sure the host allows you to put the interface into promiscous mode. The Security page provides explanations why this is a good idea. To be secure (at least in a way), it is recommended that even an administrator should always run in an account with (limited) user privileges, and only start processes that really need the administrator privileges. The way this is done differs from operating system to operating system. You need to run Wireshark or TShark on an account with sufficient privileges to capture, or need to give the account on which you're running Wireshark or TShark sufficient privileges to capture. ![]() I used no special tricks on the first system. Npf is the WinPCAP driver!! So, the focus here needs to be in getting the WinPCAP driver installed and running in a system that seems to not want to do that. One comment that Wireshark doesn't need npf if running as admin has to be pure BS. You may have trouble capturing or listing interfaces After some research I tried the command sc start npf. I've installed the following packages: WinPcap 4.1.3 Wireshark 1.8.6 When I try to run Wireshark I get the message: The NPF driver isn't running. ![]() During installation of Wireshark and WinPcap I ran into some problems. ![]()
