Start Wireshark as non-root and ensure you see the list of interfaces and can do live capture. Sudo setcap cap_net_raw,cap_net_admin+eip /usr/sbin/dumpcap (NOTE: Replace /usr/sbin with /usr/bin in case you receive an error that indicates that dumpcap isn't in /usr/sbin) Setting network privileges for dumpcap if your kernel and file system support file capabilitiesĮnsure that you have installed the necessary tools, such as the setcap command. Other Linux distributions may require that you give dumpcap sufficient privileges by hand. Other Linux based systems or other installation methods To allow non-root users to capture packets follow the procedure described in the Wireshark Debian, Ubuntu and other Debian derivativesīy installing Wireshark packages non-root users won't gain rights automatically to capture packets. Wireshark is provided by several distributions and some of them help in configuring dumpcap to allow capturing even for non-root users.

GNU/Linux distributions usually provide package managers which handle installation, configuration and removal of software packages. GNU/Linux distributions, Wireshark is installed using a package manager

The advantage of this solution is that while dumpcap is run as root the vast majority of Wireshark's code is run as a normal user (where it can do much less damage). This can be achieved by installing dumpcap setuid root. Wireshark has implemented Privilege Separation which means that the Wireshark GUI (or the tshark CLI) can run as a normal user while the dumpcap capture utility runs as root.

This can obviously be automated using a batch file.ĭisadvantage: You'll have to enter the password each time you start/stop Wireshark. Start Wireshark as a user and work with it, including capturing, until the specific job is finished. Using Wireshark running in a user account could look like:

You can start the driver by hand before starting Wireshark and stop it afterwards. In the registry you can change HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NPF\Start from 0x3 (SERVICE_DEMAND_START) to 0x2 (SERVICE_AUTO_START) or 0x1 (SERVICE_SYSTEM_START).Īs the driver is already started you can run Wireshark as user all the time.ĭisadvantage: Every local user can always capture live data. (This must be run as Administrator under Vista.) In the driver properties you can set the startup type as well as start and stop the driver manually.įrom the command line you can run sc config npf start= auto

You can change the start settings of the NPF service to "automatic" or "system" at any time using the following methods:įrom the Device Manager you can select View->Show hidden devices, then open Non-Plug and Play Drivers and right click on NetGroup Packet Filter Driver. 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. Limiting capture permission to only one group.
