Termshark

A terminal user-interface for tshark, inspired by Wireshark.

V2.4 is out now with packet search and profiles for colors and columns! See the ChangeLog.

If you're debugging on a remote machine with a large pcap and no desire to scp it back to your desktop, termshark can help!

Features

• Read pcap files or sniff live interfaces (where tshark is permitted)
• Filter pcaps or live captures using Wireshark's display filters
• Reassemble and inspect TCP and UDP flows
• View network conversations by protocol
• Copy ranges of packets to the clipboard from the terminal
• Written in Golang, compiles to a single executable on each platform - downloads available for Linux, macOS, BSD variants, Android (termux) and Windows

tshark has many more features that termshark doesn't expose yet! See What's Next.

Install Packages

Termshark is pre-packaged for the following platforms: Arch Linux, Debian (unstable), FreeBSD, Homebrew, MacPorts, Kali Linux, NixOS, SnapCraft, Termux (Android) and Ubuntu.

Building

Termshark uses Go modules. Set GO111MODULE=on then run:

go install github.com/gcla/termshark/v2/cmd/termshark

For versions of Go between 1.14 and 1.17, use

go get github.com/gcla/termshark/v2/cmd/termshark

Then add ~/go/bin/ to your PATH.

For all packet analysis, termshark depends on tshark from the Wireshark project. Make sure tshark is in your PATH.

Quick Start

Inspect a local pcap:

termshark -r test.pcap

Capture ping packets on interface eth0:

termshark -i eth0 icmp

Run termshark -h for options.

Downloads

Pre-compiled executables are available via Github releases. Or download the latest build from the master branch - .

Documentation

See the termshark user guide, and my best guess at some FAQs. For a summary of updates, see the ChangeLog.

Dependencies

Termshark depends on these open-source packages:

• tshark - command-line network protocol analyzer, part of Wireshark
• tcell - a cell based terminal handling package, inspired by termbox
• gowid - compositional terminal UI widgets, inspired by urwid, built on tcell

Note that tshark is a run-time dependency, and must be in your PATH for termshark to function. Version 1.10.2 or higher is required (approx 2013).
