Start MinIO in a distributed setup, with 'ftp/sftp' enabled.

```
minio server http://server{1...4}/disk{1...4}
   --ftp="address=:8021" --ftp="passive-port-range=30000-40000" \
   --sftp="address=:8022" --sftp="ssh-private-key=/home/miniouser/.ssh/id_rsa"
...
...
```

Following example shows connecting via ftp client using `minioadmin` credentials, and list a bucket named `runner`:

```
