![]() In order for it to make quite a lot more sense, I’ll share what I’ve just learnt. If you look at the above suggested “better way” here, this will make a “little” more sense. Dumpcap needs to run as root, wireshark does not need to run as root because it has Privilege Separation. dumpcap is the executable responsible for the low level data capture of your network interface. This will work, but of course it’s not a good idea to run a comprehensive tool like Wireshark (over 1’500’000 lines of code) as root. You can try running Wireshark as root: gksudo wireshark When you try to specify an interface from which to capture, you will probably notice the error “There are no interfaces on which a capture can be done.” When you first install Wireshark and try to start capturing packets, you will probably notice the error “You didn’t specify an interface on which to capture packets.” If you’re a windows user, you can check out the Windows notes here. This post is targeted at getting Wireshark running on Linux. Wireshark can’t alter the traffic, it can’t decrypt SSL traffic unless the encryption key can be provided and Wireshark is compiled against GnuTLS. I decided to use Burp Suite as the Http proxy interceptor and Wireshark as the network sniffer (not an interceptor). To start capturing again just click the blue button beside the red stop button.As part of my journey with Node.js I decided I wanted to see exactly what was happening on the wire. ![]() Step 3: After capturing all the required packets that you want you can stop by simply clicking the red square button at the top-left. You can also apply filters by protocol names to see only the packets you want to see. The Protocol is showing currently which network protocol is running on your system and their source and destination IP addresses. This is where you are capturing the protocols. Step 2: You can see a window with various source and destination IP addresses, protocols, lengths, etc. Step 1: Go to Wireshark and double click on the first option enp0s3 to start capturing To capture the networking packages using Wireshark follow these steps If you face any error during installation or running Wireshark like Wireshark xdg_runtime_dir not set then open the terminal and run this command and click YES to the message box sudo dpkg-reconfigure wireshark-commonĪfter opening Wireshark if you can see wavy lines beside enp0s3 then congratulations, you are all set and good to go.
