Environment variables
  • N3FJP_HOSTN3FJP API host.
  • N3FJP_PORTN3FJP API port (Settings → Application Program Interface). Default 1100. Not the multi-PC networking port.
  • N3FJP_TIMEOUTSeconds to wait for an N3FJP response.
  • N3FJP_ALLOW_DB_WIPEDANGER. When off (default), raw SQL that could delete/overwrite the entire log (DROP/TRUNCATE, unscoped DELETE/UPDATE) is refused. Only enable with a backup and full understanding of the risk.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.
