Termshark a terminal user interface for tshark

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!

What is Termshark?

Termshark is a terminal user interface for Tshark, inspired by Wireshark.

⚡ TSharkis a network protocol analyzer. 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.

TShark‘s native capture file format ispcapng, which is also the format used byWiresharkand various other tools.

Termshark 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 additional features that Termshark does not yet expose! SeeWhat’s Next.
