Ping-Pong using rust-libp2p TCP/IP via a Tor proxy

This is a small show case for a server/client ping-pong chat using libp2p via Tor using Tor's socks5 proxy.

Usage

See src/main.rs for a complete running example using Tor.

You should configure your Tor onion service to redirect traffic to some local port.

Example Tor configuration (e.g. in /usr/local/etc/tor/torrc)

HiddenServiceDir /usr/local/etc/tor/hidden_service
HiddenServicePort 7776 127.0.0.1:7777

Check the hidden service data directory for a file called hostname, this contains the onion address for the service.

Run server first, it will print the ONION_ADDRESS it is listening on

RUST_LOG=info cargo run
...

Use the ONION_ADDRESS and start the dialer:

cargo run -- --dialer --onion=ONION_ADDRESS
