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

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).
• Inspect each packet using familiar Wireshark-inspired views
• Filter pcaps or live captures using Wireshark's display filters
• 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 (+termux), macOS, FreeBSD, and Windows

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

Installation (FreeBSD)
Termshark is in the FreeBSD ports tree! To install the package, run:
pkg install termshark
To build/install the port, run:
cd /usr/ports/net/termshark/ && make install clean

Building
Termshark uses Go modules, so it's best to compile with Go 1.11 or higher. Set GO111MODULE=on then run:

go get github.com/gcla/termshark/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:

Capture ping packets on interface eth0:

Run termshark -h for options.

User Guide
See the termshark user guide (and my best guess at some FAQs)

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).
