When running the daml sandbox compiled with 2.1.1 the following ports are allocated that are not documented. 686[5,6,7,8]. Further, as it clashed with one my existing port, I was trying to found how to easily override the one clashing port but could not find an obvious documentation entry point for either issue. I used an option that is not documented in the command lined but that seems to work. Could you point me to the documentation where that is all explained if I missed it? (the 6868 port got overriden with the --domain-admin-port=6869 option in the daml sandbox command line) ---

The options are listed as part of `daml sandbox --help` but fully agree that some more documentation around the defaults and those options would be very helpful. ```haskell moritz@adjunction ~> daml sandbox --help Usage: daml sandbox [--port ARG] [--admin-api-port ARG] [--domain-public-port ARG] [--domain-admin-port ARG] [--canton-port-file PATH] [--static-time | --wall-clock-time] [--canton-help] [-c|--config FILE] [--port-file PATH] [--dar PATH] [ARG] ```
