Hello, I've modified the freeradius-client to simplify its API, remove all IPv4-only legacy code and add DTLS support (rfc7360). The DTLS support I've tried to add in a transparent way, i.e., an old client could still have basic DTLS support only by modifying its configuration file. This is currently experimental code and most likely will have bugs, but I'd like to see any comments on the approach or possible improvements. My main concern is that there have been no releases of freeradius-client for many years, although the intention is to send back the changes as pull requests to the original repository once they stabilize. regards, Nikos The code: https://github.com/nmav/radiusclient-dtls Changes since the last release of freeradius-client: https://github.com/nmav/radiusclient-dtls/blob/master/CHANGES
