iroh ping

A very simple iroh protocol for pinging a remote node. It's a high level example & easy starting point for new projects.

Walk through the quickstart example in the Documentation Website.

Running the Examples

Quickstart Example

This example demonstrates basic ping functionality between two endpoints.

First, start the receiver in one terminal:

cargo run --example quickstart receiver

The receiver will print a ticket. Copy this ticket, then in another terminal run:

cargo run --example quickstart sender <TICKET>

Replace <TICKET> with the ticket printed by the receiver.

This is not the "real" ping

Iroh has all sorts of internal ping-type messages, this is a high level demo of a protocol, and in no way necessary for iroh's normal operation.
