proftpd in docker - not optimal configurable about proftpd

[rafasc]

I believe proftpd is not writing to SystemLog in the case you described with on 2).

If you used --nodaemon, it should be writing to stdout/stderr. That output may or may not end up in your system log depending how you have your docker logging driver configured.

If you want to avoid that you may try using --quiet to tell proftpd to not write to stderr. #1287

Docker logs will still have some logs (stdout) but the majority of it should be redirected to the file configured by the ServerLog directive.

@rafasc thanks I will try so and report back if --quiet is redirecting the logs to the file defined in ServerLog.
