Strymon currently selects port 9189 to run the coordinator. We should get an assigned port instead or select one from the list of non-assignable ports. See https://tools.ietf.org/id/draft-cotton-tsvwg-iana-ports-00.html for more details.

  o  the Dynamic Ports, also known as the Private or Ephemeral Ports,
     from 49152-65535 (never assigned)

I'd be up for that. Note that there is also some additional port selection done by multi-machine Timely > jobs. By default, they use currently use the port range 2101-4101.

strymon-core/src/strymon_runtime/src/executor/mod.rs

Line 125 in f79a083

ports: (2101, 4101),
