![]() It will use the pcap library to capture traffic from the first available network interface and displays a summary line on the standard output for each received packet. Without any options set, TShark will work much like tcpdump. TShark's native capture file format is pcapng format, which is also the format used by Wireshark and various other tools. It lets you capture packet data from a live network, or read packets from a previously saved capture file, either printing a decoded form of those packets to the standard output or writing the packets to a file. Analyze packets from a file: tshark -r path/to/file.pcap.Write captured packet to a file: tshark -w path/to/file.Select specific fields to output: tshark -T fields|ek|json|pdml -e -e ip.src.Specify the format of captured output: tshark -T json|text|ps|….Decode a TCP port using a specific protocol (e.g.Only show packets matching a specific output filter: tshark -Y ' = "GET"'.Only capture packets matching a specific capture filter: tshark -f ' udp port 53'.Monitor everything on localhost: tshark.More about using Termshark is available in its user guide and FAQ.Dump and analyze network traffic Examples (TL DR) Or read from an interface and apply a tcp capture filter directly using: Launch Termshark and set it to read from an interface ( enp4s0 in this example change this to an interface available on your system): Replace myfile.pcap with the name (and path) of the pcap file. On both Ubuntu and Fedora (and other Linux distributions) you'll also need to add your user to the wireshark group (created by the installation of TShark - if not, add this group using sudo groupadd wireshark) to be able to run TShark, and thus Termshark, without root:Īfter this, I had to reboot my Ubuntu 19.04 and Fedora 29 machines (usually you're supposed to logout/login but that wasn't enough in my case). When prompted, answer Yes to the Should non-superusers be able to capture packets? question. So to install TShark on Debian, Ubuntu, Linux Mint, etc., use: For example it's tshark on Debian / Ubuntu, while the package that provides TShark on Fedora is called wireshark-cli. On Linux the package name depends on the distribution you're using. This is part of Wireshark, and on macOS you can install it using brew ( brew install wireshark). To work, Termshark needs TShark to be installed. To install the Termshark binary on Linux, get it from GitHub, extract it, and from the folder where it's extracted you can install it to /usr/local/bin using: Or you can build it yourself if you prefer. The Termshark releases page has binaries for Linux (圆4 and armv6), macOS and Windows. All the available keyboard shortcuts are shown by pressing ?.Īlso see: Wireless Sniffer Kismet 2019-04-R1 Adds New Web UI, Support For Non-WiFi Captures You can also adjust the horizontal ( /-) or vertical ) split, or maximize the pane ( \). The interactive network traffic analyzer includes some handy keyboard shortcuts, like / to go to the display filter, TAB to switch panes, c to switch to copy-mode, etc. The developer plans to improve Termshark, with quite a few features being planned, like the ability to select a packet and display the reassembled stream, show pcap statistics, colorize the packets in the packet list view using the Wireshark coloring rules, and more. I preferred not to add it to this article as it's a bit too large (3mb). If you want to see it in action, there's a Termshark GIF on its homepage. Copy ranges of packets to the clipboard from the terminal.Filter pcaps or live captures using Wireshark's display filters.Inspect each packet using familiar Wireshark-inspired views.Read pcap files or sniff live interfaces (where TShark is permitted).The command line tool had its first release a few days ago, so don't expect it to support all of TShark's features just yet. ![]() Its interactive terminal interface uses tcell, a cell-based terminal handling package inspired by termbox, and gowid, a Go package that provides widgets and a framework for making terminal user interfaces. Termshark is written in Go, and makes use of TShark which is part of Wireshark. TShark doesn't have an interactive terminal user interface though, and this is where Termshark comes in. TShark is a terminal version of Wireshark, the free and open source packet analyzer used for network troubleshooting, analysis, software and communication protocol development. Termshark is a new terminal user interface for TShark (network protocol analyzer), inspired by Wireshark.
