Tabby Connection Gateway

This is the connection gateway service that Tabby Web uses. It's a Websocket → TCP gateway that allows Tabby to initiate arbitrary network connections from a browser.

You can host one yourself to prevent the connection traffic from going through the central connection gateway that I'm hosting.

Once started, you'll just need to enter your gateway URL and a secret token in the Tabby Web settings, and all future connections will go straight through your own gateway.

Installation

pip3 install tabby-connection-gateway

Usage

TCG runs one Websocket listener for the incoming connections and one optional Websocket listener for management requests.

The management/admin listener is only used on Tabby Web's own managed gateways to authenticate new connections. For your local instance, you need to generate your own secret token and pass it via the TABBY_AUTH_TOKEN environment variable.

Running with SSL

Note that if you're using Letsencrypt, you need to run the gateway on port 443 as they don't provide non-standard port certificates.

TABBY_AUTH_TOKEN="123..." tabby-connection-gateway --host 0.0.0.0 --port 443 --token-auth --certificate ssl.pem --key ssl.key

Connection gateway URL for Tabby settings: wss://<host>

You could theoretically add --ca ca.pem to enable client certificate auth, but AFAIK browsers (at least Chrome) don't support it with Websockets.

Running without SSL

TABBY_AUTH_TOKEN="123..." tabby-connection-gateway --host 0.0.0.0 --port 1234 --token-auth

Connection gateway URL for Tabby settings: ws://<host>:1234
