Termshark- To Analyze Network Traffic

Termshark
Termshark

Termshark is a terminal UI for Tshark, which is inspired by Wireshark.

If you are 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
  • Reassemble and inspect TCP and UDP flows
  • 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, FreeBSD, Android (termux) and Windows

Install Packages

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

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

go install 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.

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.
