Secure Terminal Sharing

Project maintained by jingweno Hosted on GitHub Pages — Theme by mattgraham


Upterm is an open-source solution for sharing terminal sessions instantly with the public internet over secure tunnels.

What it’s good for



brew tap jingweno/upterm
brew install upterm


upterm can be easily installed as an executable. Download the latest compiled binaries and put it in your executable path.

From source

git clone git@github.com:jingweno/upterm.git
cd upterm
GO111MODULE=on go install ./cmd/upterm/...

Quick Start

# Host a terminal session by running $SHELL
# The client's input/output is attached to the host's.
$ upterm host

# Display the ssh connection string
$ upterm session current
Command:                /bin/bash
Force Command:          n/a
Host:                   uptermd.upterm.dev:22
SSH Session:            ssh bo6nosstp9ll08doq0rg:MTAuMC4xNzAuMTY0OjIy@uptermd.upterm.dev

# Open a new terminal and connect to the session
$ ssh bo6nosstp9ll08doq0rg:MTAuMC4xNzAuMTY0OjIy@uptermd.upterm.dev

# Host a session with a custom command.
# The client's input/output is attached to the host's.
$ upterm host -- docker run --rm -ti ubuntu bash

# Host a session by running 'tmux new -t pair-programming'.
# The host runs 'tmux attach -t pair-programming' after the client joins the session.
# The client's input/output is attached to this command's.
$ upterm host --force-command 'tmux attach -t pair-programming' -- tmux new -t pair-programming`,

How it works

You run the upterm program and specify the command for your terminal session. Upterm starts an SSH server (a.k.a. sshd) in the host machine and sets up a reverse SSH tunnel to a Upterm server (a.k.a. uptermd). Clients connect to your terminal session over the public internet via uptermd using ssh. A community Upterm server is running at uptermd.upterm.dev and upterm points to this server by default.
