#31874: Automatically test the PTs of bridges ---------------------------+-------------------------------- Reporter: phw | Owner: (none) Type: defect | Status: new Priority: Medium | Milestone: Component: Circumvention | Version: Severity: Normal | Resolution: Keywords: s30-o23a3 | Actual Points: Parent ID: #31280 | Points: 10 Reviewer: | Sponsor: Sponsor30-must ---------------------------+--------------------------------
Comment (by phw): Here are some thoughts on building a new service that would allow both BridgeDB ''and'' bridge operators to test bridges: * The service should expose a web interface and an API: The web interface is meant for bridge operators who want to test their new bridges, and can replace our [https://bridges.torproject.org/scan/ obfs4 port scan tool]. The API is meant for BridgeDB, allowing it to test the bridges it knows about. We need to be sure that there's no interference that would allow web interface users to learn what bridges were tested over the API, so we may want to run two instances of this service. * The API should be a simple JSON-based REST API. Requests should go to, say bridges.torproject.org/api/test, and have the following request body: {{{ {bridge_line: "1.2.3.4:443"} }}} The service should then respond with something along the lines of: {{{ {functional: true, error: null, time: 4.215} }}} (Note that these are mere examples.) * The web interface [https://trac.torproject.org/projects/tor/attachment/ticket/31874/bridge- test-web-ui.png can look like this]. * The service can take as input bridge lines (vanilla or pluggable transports), spawns a Tor process with the given bridge line, and parses Tor's output to determine if the bridge bootstrapped correctly. This has the potential to be quite messy. What's a better design? * How should BridgeDB use this service? At the very least, it should periodically test all its bridges and log the ones that don't work, making it easy for BridgeDB's maintainers to contact the respective bridge operators. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/31874#comment:2> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
