It is vital to keep a perspective on the problem and realize that the error is unlikely to be caused by Wireshark itself. If you keep getting communication error messages when opening Wireshark, you will get frustrated and stressed. If nothing can get onto the internet, you have identified the problem and you should call in a support specialist to get your network access problems fixed. If anything can get onto the network, the problem doesn’t lie with the physical network card or the network adapter software. Try any other network-active application on your computer to see if it can get access to the network. So, if Wireshark is not getting through to the network, nothing should be getting through. There is no reason why your network interface should block Wireshark and allow all other applications to get access to the network. Wireshark is just one of many network-enabled applications on your computer. Having wifi turned off or blocked will not invoke the “no interfaces found” error. If you only have access to wifi and you have wifi turned off or you have your network setting in airplane mode, Wireshark should still be able to see the network adapter.

If none of the above tests on the software running on your computer solve the problem, you will need to test your network card. Set Wireshark as an exception in your firewall rules and turn the firewall back on again. If it now manages to find the network, the problem lies with your firewall. Open Wireshark again to get it to look for networks.

However, just in case the problem lies with your computer’s firewall software try the following test.Ĭlose down Wireshark and turn off your firewall. Your firewall shouldn’t be blocking Wireshark’s access to the network because firewalls generally work to prevent external processes from getting onto your computer not to prevent processes on your computer getting to the network.

If the code for Wireshark is in bin and not sbin, change “ /usr/sbin/” to “ /usr/bin/” in the above command. If the above commands don’t work on your version of Linux, try: chown root /usr/sbin/dumpcap If the above command returns an error, try: setcap ‘CAP_NET_RAW+eip CAP_NET_ADMIN+eip’ /usr/bin/dumpcap It may be that the Wireshark code is held in the bin directory instead of sbin. Not every flavor of Linux behaves in exactly the same way, so if just nominating dumpcap as a root process doesn’t work, try the following command: setcap ‘CAP_NET_RAW+eip CAP_NET_ADMIN+eip’ /usr/sbin/dumpcap This is dumpcap you need to run the following command to get this module set up properly. Again, Wireshark doesn’t need to run as root on Linux, but there is one element of the program suite that does. This often solves the problem of Wireshark’s inability to access the network functions on a Linux computer. This action runs the normal program with superuser network privileges. It seems that it needs to be run with the sudo command. Linux users report a different situation when running Wireshark. It is this installation phase that requires you to restart your computer. The installation process sets WinPcap to run on system startup and also writes it to the register so that it can run with admin rights level.

The setup process of Wireshark will install WinPcap for you. This is WinPcap, which is the underlying service that assists in capturing packets. One element of the Wireshark suite of programs does need administrator network privileges. This is because as far as the network procedures of your computer are concerned, Wireshark is only acting the way any other program that connects to the network would behave ‒ the Wireshark system only needs access to the network, which is available to all regular users, not just the administrator. Surprisingly, in Windows, you do not need to run Wireshark with administrator network privileges to give the program access to network functions. There are many possible reasons for this problem. When Wireshark reports that it cannot find any “interfaces”, it means that it could not detect any networks. Interface error caused by access permissions So, if Wireshark can’t find any networks at all, you can’t progress to the packet capture phase. To capture network traffic packets, you first need to select one of these networks.

The error message appears in the area of the application window where you would expect to see a list of available networks. On the initial scan, if the program cannot find any networks attached to the computer on which it is running, it will show the message “ No interfaces found.” Towards the end of its startup procedures, Wireshark scans the host computer for network connections.

When you start up Wireshark to capture network packets, the tool has to go through a series of initialization routines. “There are no interfaces on which a capture can be done.”
