shwim 26.2.0

Encrypted, peer-to-peer terminal sharing for two people.

SHell WIth Me lets a “host” share their terminal with a “guest” peer on another computer.

This combines the cryptography of Magic Wormhole (via Fowl) and the terminal-sharing of tty-share into a secure, end-to-end encrypted, peer-to-peer terminal sharing application.

Getting Started

To install, use pip install shwim (see longer instructions below). This should enable you to run shwim --help.

The Host computer runs shwim by itself, producing a <magic-code>. The Guest computer runs shwim <magic-code>.

You are now sharing a single terminal running on “host”. Beware: the guest can type, run commands, etc. so only do this with humans you would hand your local keyboard over to.

The Host may pass --read-only to ignore input from the Guest.

Slightly Longer Explanation

Once the two things happen (i.e. “shwim” on the host and “shwim ” on the guest), there is a secure tunnel between both computers. The host will decide a random port and run tty-share as a server; the guest will run tty-share as a client.

On both computers, tty-share will be running as a subprocess with correct options to do networking via Magic Wormhole only. All raw-mode terminal I/O is forwarded to this tty-share process so things like curses etc work as expected.

Once either side exits, the networking forwarding is done – there is no long-term credential sharing or any other network set preserved or altered on the “host” nor “guest” computers.
