SynoCtrl Build status

SynoCtrl is a command-line program to remotely control your Synology NAS


  • Show Synology status (synoctrl status-all [<name>] [--info] [options])
  • Shutdown Synology NAS (synoctrl shutdown [<name>] [options])
  • Reboot Synology NAS (synoctrl reboot [<name>] [options])
  • Boot up Synology NAS via WOL (synoctrl wol [<name>] [options])
  • Send ping package (synoctrl ping [<name>] [options])
  • Get IP adress by MAC (synoctrl getip [<name>] [options])
  • Get MAC address by IP via ARP (synoctrl getmac [<name>] [options])


You do not need to create a configuration file and can use SynoCtrl completely portable only via command-line parameter.
But (for convenience) you can specify properties of your NAS (or multiple NAS') in a config file and reference them in your program call:

Default = "MyDevice"             # The default device to use if no specific device is specified
                                 # Can be removed if there shall be no default device.

Name     = "MyDevice"            # Device name
IP       = ""        # IP address (optional)
Port     = 1924                  # Port of DiskStation WebInterface (optional)
HTTPS    = false                 # Enable HTTPS Communication (optional)
Mac      = "00-11-22-33-44-55"   # MAC address (optional)
Username = "usr"                 # DSM Web interface username (optional)
Password = "pass"                # DSM Web interface password (optional)

# You can add more than one device:

# [[Device]]
# Name     = "Demo2"               # Device name
# IP       = ""         # IP address (optional)
# Port     = 1924                  # Port of DiskStation WebInterface (optional)
# HTTPS    = false                 # Enable HTTPS Communication (optional)
# Mac      = "00-A1-B2-C3-D4-E5"   # MAC address  (optional)
# Username = "admin"               # DSM Web interface username (optional)
# Password = "admin"               # DSM Web interface password (optional)

# You can add more devices here and use them by their device-names in the command-line interface
# ...

(This is TOML syntax)

Then you can call synoctrl shutdown MyDevice to shutdown the device with the name "MyDevice".
If no config file exists or no device name is given you have to supply all necessary parameters via command-line parameter (In this case --ip, --username, --password)

All fields except the Name field are optional in the TOML config file are optional and can be removed, in this case you need to supply these parameters in the program call if they are necessary.

The config file location can be set with the command line parameter --config. If no --config parameter is set the standard locations are searched for a config file (in this order):

  • %program_dir%\synoctrl.toml
  • %userprofile%\.config\synoctrl.toml
  • %userprofile%\synoctrl.toml
  • %appdata%\synoctrl\synoctrl.toml

You can create a example config file with the command synoctrl create-config synoctrl.toml

Options / Command-line parameter

Parameter Description
-h --help Show the command-line help
--version Show the version
--mac <mac> The MAC address of the device
--ip <ip> The IP address of the device
--port <port> The Port of the DSM Web interface (if not set the default port 5000/5001 is used
--https Use a TLS encrypted connection to the DSM Web interface
-u <user> --user <user> The username for the DSM Web interface (and API)
-p <pass> --password <pass> The password for the DSM Web interface (and API)
-c <config> --config <config> Use the config file at this specific path, do not search in other places
-s, --silent Only output the result (or errors), useful if you want to parse the output
-v, --verbose Output debug/trace messages, useful for debugging



You can shutdown the device Melkor with the command synoctrl shutdown MyDevice.
This uses the Synology DSM API to send an shutdown request.
If you do not have a configuration file you can supply all parameter by yourself:
synoctrl shutdown --ip --user admin --password admin
If you want to reboot your device (instead of shutdown) you can use the reboot command synoctrl reboot MyDevice

Boot-up (Wake-on-LAN)

You can boot the device by sending a Wake-on-LAN package to the MAC address of your NAS.
For this to work you have to enable WOL in your device config.
The command is synoctrl wol MyDevice, if you do not have a configured device the command is synoctrl wol --mac 00:11:22:33:44:55

Get IP/MAC address

For convenience two commands are available to get the MAC address from an IP address (via ARP) and to get the IP address from a MAC address (via you local ARP table):
synoctrl getip MyDevice and synoctrl getmac MyDevice or synoctrl getip --mac 00:11:22:33:44:55 and synoctrl getmac --ip
For obvious reasons getip only works when the device is powered on (and accepts ARP requests) and getmac only works if the device is already in your local ARP table.


SynoCtrl can show many different status fields. All these data is gathered via the API, so if you don't have a config file with the respective data supplied you need to at least set the parameters --ip, --username and --password.

You can list all available status fields with synoctrl status-list (see Appendix 1).

The status-all command returns all available status fields, this can take a moment because multiple API endpoints have to be called. (synoctrl status-all MyDevice).

But the normal way is to call status together with a comma-separated list of fields you want to get:
synoctrl status Model,MemoryUsageReal,Uptime MyDevice or synoctrl status Load5min MyDevice

If you only want the raw unformatted value you can add --silent and if you want the value together with the field description you can add --info
