• SSL/TLS debugging on MariaDB

    From Andrew Wood@21:1/5 to All on Mon Sep 23 22:10:01 2024
    Hi

    Is there a way to get  MariaDB on Bookworm to log verbosely everything
    to do with connection attempts in order to try and debug why a client
    keeps getting error  2026 SSL connection error: protocol version mismatch?

    There is currently nothing being logged on the server other than:

     [Warning] Aborted connection 332 to db: 'unconnected' user: 'unauthenticated' host: '192.168.253.231' (This connection closed
    normally without authentication)

    SHOW GLOBAL VARIABLES LIKE 'tls_version'; gives TLSv1.1,TLSv1.2,TLSv1.3
    and the client is based on a relatively recent version of libmysqlclient
    so Im struggling to understand what is going wrong without some more
    detailed logging. I cant find anything in the MariaDB manual.

    Thanks

    Andrew
