Expose the UI to other machines

By default, Alloy listens on the local network for its HTTP server. This prevents other machines on the network from being able to access the UI for debugging.

To expose the UI to other machines, complete the following steps:

Follow Change command-line arguments to edit command line flags passed to Alloy.
Add the following command line argument:
shell
```
--server.http.listen-addr=LISTEN_ADDR:12345
```
Replace the following:
- <LISTEN_ADDR>: An IP address which other machines on the network have access to. For example, the IP address of the machine Alloy is running on.
  To listen on all interfaces, replace <LISTEN_ADDR> with 0.0.0.0.
