## Checking that Garage runs correctly
|
||||
|
||||
The `garage` utility is also used as a CLI tool to configure your Garage deployment.
|
||||
It tries to connect to a Garage server through the RPC protocol, by default looking
|
||||
for a Garage server at `localhost:3901`.
|
||||
It uses values from the TOML configuration file to find the Garage daemon running on the
|
||||
local node, therefore if your configuration file is not at `/etc/garage.toml` you will
|
||||
again have to specify `-c path/to/garage.toml`.

Since our deployment already binds to port 3901, the following command should be sufficient

to show Garage's status:
