# `mix dala.port`
[🔗](https://github.com/ohhi-vn/dala_dev/blob/main/lib/mix/tasks/dala.port.ex#L1)

Prints which host ports belong to which device, and flags processes that
are squatting on them.

    mix dala.port                # table: device → dist / LV ports + status
    mix dala.port --kill         # kill any process squatting on a needed port
    mix dala.port --json         # machine-readable

Ports covered:

  * `4369` EPMD — shared by every device on this host
  * `9100+` dist — one per device (index order matches the deployer)
  * LiveView — hashed from the app name in [4200..4999]

A "listening" row is normal when the owning app/BEAM is alive; it's a
problem when the owner is dead or wrong (stale iproxy, previous app
instance). `--kill` frees those so the next deploy can bind.
