Echo Server

Echo Server

There is an initial version of a simple echo server located at nym/tools/echo-server (opens in a new tab).

This is an initial minimal implementation of an echo server built using the NymProxyServer Rust SDK abstraction that, aside from the initialisation and running of a NymProxyServer instance in the background, is essentially a vanilla TCP echo server written with tokio.

This server was initially built for the TcpProxy tests, but can be useful for developers to need a constant endpoint to ping when developing. In the future this will be deployed to a remote server so developers don't have to run their own.

Build

Run cargo build --release from nym/tools/echo-server. The binary will be in the main workspace target/release dir.

Run

All the server requires is a port to connect the TCP listener to. If no <PATH_TO_ENV> is supplied then the server defaults to using mainnet.

echo-server <PORT> <PATH_TO_ENV_FILE>
# e.g.  ../../target/release/echo-server 9000 ../../envs/canary.env

Logging

Every 10 seconds, the server logs:

  • the total number of bytes received since startup
  • the total number of bytes sent since startup
  • the current number of concurrent connections it has
  • the total number of concurrent connections it has
