# Controlling and querying lbcd via lbcctl

lbcctl is a command line utility that can be used to both control and query lbcd
via [RPC](http://www.wikipedia.org/wiki/Remote_procedure_call).  lbcd does
**not** enable its RPC server by default;  You must configure at minimum both an
RPC username and password or both an RPC limited username and password:

* lbcd.conf configuration file

```bash
[Application Options]
rpcuser=myuser
rpcpass=SomeDecentp4ssw0rd
rpclimituser=mylimituser
rpclimitpass=Limitedp4ssw0rd
```

* lbcctl.conf configuration file

```bash
[Application Options]
rpcuser=myuser
rpcpass=SomeDecentp4ssw0rd
```

OR

```bash
[Application Options]
rpclimituser=mylimituser
rpclimitpass=Limitedp4ssw0rd
```

For a list of available options, run: `$ lbcctl --help`
