Connecting to WPA[1,2,3] Enterprise without certificates

This method assumes EAP-PEAP MSCHAPv2.

Should you do this?

You should not be doing this, but if you want to... here is how you can use wpa_supplicant and OpenSSL for enterprise connections with no certs. This is a bad idea. You should be setting up certs and a proper PKI, but here we go...

Edit /etc/ssl/openssl.cnf

Logging setup for FastAPI

This logging setup configures Structlog to output pretty logs in development, and JSON log lines in production.

Then, you can use Structlog loggers or standard logging loggers, and they both will be processed by the Structlog pipeline (see the hello() endpoint for reference). That way any log generated by your dependencies will also be processed and enriched, even if they know nothing about Structlog!

Requests are assigned a correlation ID with the asgi-correlation-id middleware (either captured from incoming request or generated on the fly). All logs are linked to the correlation ID, and to the Datadog trace/span if instrumented. This data "global to the request" is stored in context vars, and automatically added to all logs produced during the request thanks to Structlog. You can add to these "global local variables" at any point in an endpoint with `structlog.contextvars.bind_contextvars(custom
