syno-cli

Provides a command-line interface for a Synology DiskStation allowing to list shares and lock/unlock encrypted volumes.

It allows to unlock several volumes at once by providing JSON with a list of shares and their corresponding passwords. If you have a lot of shares and install the frequent security updates (which you should), this might make your life easier.

Example

$ export SYNO_BASE_URL='https://myds.example.net:5001'
$ export SYNO_USER='api'
$ export SYNO_PASSWORD='password'
$ syno-cli list
[ debug messages... ]
backup          Encrypted, locked
homes           Not encrypted        user home
public          Not encrypted
sync            Encrypted, locked
$ cat shares.json
[
    {"name": "backup", "password": "secret"},
    {"name": "sync", "password": "secret2"}
]
$ cat shares.json | syno-cli unlock --batch
[ debug messages ...]

Installation

You'll need Go. Once you have Go and set a GOPATH, you can install syno-cli:

go get frister.net/go/syno-cli

Usage

syno-cli reads configuration from the following environment variables.

• SYNO_BASE_URL - your DiskStation's URL with protocol and port, e.g. https://myds.example.net:5001
• SYNO_USER - the user to log in as
• SYNO_PASSWORD - the user's password

usage: syno-cli <command> [<flags>] [<args> ...]

Flags:
  --help  Show help.

Commands:
  help [<command>]
    Show help for a command.

  list
    List shares

  lock <share name>
    Lock an encrypted volume

  unlock [<flags>] [<share name>]
    Unlock an encrypted volume

JSON format for batch unlock

It's just an array of objects with a name and a password attribute:

[
    {"name": "backup", "password": "secret"},
    {"name": "sync", "password": "secret2"}
]

Limitations

• syno-cli logs the user in, but not out, so the session id is still valid after it quits.
• The API sometimes returns error 119. No idea why, a retry helps.
• There's still a lot of debug output, including all HTTP requests including credentials.

Synology API documentation

I couldn't find any documentation for the part of the API this tool uses, but there's documentation for another part of the DiskStation API (FileStation).

Fortunately, the web interface uses the same API, so opening the network tab of a browser's developer tools and doing the actions in the UI gives you the requests.
