One may consider it as a metric to analyze the efficiency of a network that is influenced by network packets.Īlongside its cross-platform support, Wireshark is a free and open-source tool for network analysis. Wireshark analyzes the data packets and presents the details of each packet. Check out this official DOCUMENTATION for more of what you can do with Wireshark.Wireshark is a cross-platform network analyzer tool used by Network Administrators, Security Engineers, Developers, and other stakeholders of the network analysis team in an organization. Professionals use it to debug network protocol implementations, examine security problems and inspect network protocol internals. Wireshark is an extremely powerful tool, and this tutorial is just scratching the surface of what you can do with it. ConclusionĪs I mentioned earlier, Wireshark is available on all platforms but none of these other platforms has the feature parity of Linux. By default, green is TCP traffic, dark blue is DNS traffic, light blue is UDP traffic, and black identifies TCP packets with problems - for example, they could have been delivered out-of-order.

Wireshark uses colors to help you identify the types of traffic at a glance. You’ll probably see packets highlighted in green, blue, and black. If you’re capturing on a wireless interface and have promiscuous mode enabled in your capture options, you’ll also see other the other packets on the network. Wireshark captures each packet sent to or from your system. You can configure advanced features by clicking Capture Options.Īs soon as you click the interface’s name, you’ll see the packets start to appear in real time. For example, if you want to capture traffic on the wireless network, click your wireless interface.

How To Use Wireshark To Inspect Network Packets In Linux? Capturing PacketsĪfter downloading and installing Wireshark, you can launch it and click the name of an interface under Interface List to start capturing packets on that interface.

Colorize packet display based on filters.

Export some or all packets in a number of capture file formats.

Display packets with very detailed protocol information.

Import packets from text files containing hex dumps of packet data.

Open files containing packet data captured with tcpdump/WinDump, Wireshark, and a number of other packet capture programs.

Capture live packet data from a network interface.

The following are some of the many features Wireshark provides: Others use it to learn network protocol internals Features At A Glance.Developers use it to debug protocol implementations.Network security engineers use it to examine security problems.Network administrators use it to troubleshoot network problems.Here are a few examples of what people use Wireshark for: Wireshark has quite an extensive application or use. Verify the change – sudo getcap /usr/bin/dumpcap What Wireshark Is Used For?

Grant capabilities with setcap – sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap sudo groupadd wiresharkĪdd your username to the Wireshark group – sudo usermod -a -G wireshark USERNAMEĬhange the group ownership of file dumpcap to wireshark – sudo chgrp wireshark /usr/bin/dumpcapĬhange the mode of the file dumpcap to allow execution by the group wireshark – sudo chmod 750 /usr/bin/dumpcap “No interface can be used for capturing in this system with the current configuration”.The following steps will rectify this.Ĭreate a Wireshark group. If you run Wireshark as a non-root user (which you should) at this stage you will encounter an error message which says.

To install Wireshark just enter the following command in your terminal – sudo apt-get install Wireshark Wireshark will then be installed and available for use. Wireshark is a cross-platform tool that runs on Linux, Microsoft Windows, macOS, BSD, Solaris, and other Unix-like operating systems. It lets you see what’s happening on your network at a microscopic level and is the de facto (and often de jure) standard across many commercial and non-profit enterprises, government agencies, and educational institutions. It is used for network troubleshooting, analysis, software, and communications protocol development. Wireshark is a free and open-source packet analyzer.
