Synology is sometimes treated like it's simply another regular Linux distro, but that's not accurate. There are certain packages and options available to Debian etc. that are either not common, or just not possible on Synology.
Below are some lesser known ways to get access to a bunch of helpful tools:
Synogear Diagnosis Tool
This includes around 30 different tools which can be used out of the box.
- SSH into your synology machine
- Type in
This will put you into
[email protected][NASname]:/volume1/homes/[USER]. For some reason this doesn't persist between sessions, so each time I've wanted to use a tool from the list below from a new session, I've had to run step 2 above again.
To see a list of all the tools available, type in
To run any of the tools, type the following:
In general, most tools won't need an argument to run, for instance you can load up
nethogs by typing
My favourites at the moment are
htop(normally already available on Synology machines)
iftop. If you need to find out what anything listed does, google is your friend:

This process used to be part of File Finder but not too long ago was turned into its own package. Some users don't want or need this, and others may want to simply disable it at times as it can be very CPU heavy when running.
It cannot be disabled or removed from Package Finder, so the following are some simple SSH commands which can be used instead from root:
rootmode (type in your password when prompted):
sudo su -
- To disable the package:
synoservicecfg --disable pkgctl-SynoFinder
- To completely remove the package:
synopkg uninstall SynoFinderopkg
- To re-enable the package:
synoservicecfg --enable pkgctl-SynoFinder
disabling (and by extension removing) Universal Search will also affect the functionality of your Synology Drive package due to dependencies the latter has on the former
It seems that the
synoservicecfg command has been removed in DSM7. To check whether your Universal Search is enabled or not, the new command is:
synopkg status SynoFinder
This will return something like
SynoFinder package is stopped and a status number.
The uninstall command remains the same.
The Task Scheduler allows you to create tasks which run automatically at a given time or frequency (called a
Scheduled Task) or by an event such as boot up (called a
Normally if you're doing something which requires a scheduled task to be created, it will run you through the steps, however the basics:
- Open Control Panel. In the search bar type and then select
This will open a list of all your schedule tasks, showing what they do, what they're for, and when they're next set to run. Let's say we wanted to create another, for instance clearing the swap file which we want to run once a day at 5am:
Create --> Scheduled Task --> User-defined script
- Add a name for the task in the General tab, you can leave the user as
rootif desired and toggle the
Enabledcheckbox as necessary, then select the Schedule tab:
- Leave the date as
Daily, and change the
First run timeto be at 5am,
Frequencyto daily, and
Last run timeto 5am. Select the Task Settings tab:
- We define the
Run Commandin the field in one of two ways. We can either paste our script directly into it or:
- We create and save the .sh which contains the script, and reference that by 'bash'ing into it:
If you've got your emails set up you can use the tick-boxes on this page to be notified when it runs and/or terminates abnormally.
Once created and you're back on the screen showing the list of tasks, you can right-click on the task, select
Run, and if everything has been done correctly you should find that the task has run and the intended action has been started.
