Your computer is constantly running because of some downloads? After all, your NAS runs around the clock. So why not just download and use JDownloader? In our tutorial, we will show you how to install the JDownloader app on your DiskStation and run the software in the so-called headless mode.

Admittedly, the installation is extensive because the software package is not officially supported by Synology. You also need an account with “MyJDownloader”. However, this has several practical advantages, which we will discuss in a moment.

Preparing your DiskStation For Setup of JDownloader 

Since JDownloader is not an officially supported package, you have to pay more attention to the installation. First you need Java. You can find this in the package center under the heading “All packages”. Make sure that you choose Java 8 and do not install an older version.

Once you have installed the package, the next step is to add another source for applications, since you can download the JDownloader from there. Click the Settings button in the top right corner of the Package Center. Switch to the “Package sources” tab and click the add button. We use the package source from here. Assign a name for the source and insert the link in the location field.

Then click on OK, also confirm the certificate message and the settings window. Close the Package Center and open it again so that the sources are updated. But don’t install anything yet.

Create download folder for Setup of JDownloader

For JDownloader to work properly, you need a shared folder that the package can access without hindrance. Open the File Station and click the Create button. Select “Create a new shared folder” if you want to access it from the LAN. Give a name and remember it. Pay attention to upper and lower case. The Linux-based DiskStation makes a meticulous distinction here.

Click on “Next”. You can optionally encrypt the folder, which means that you have to decrypt the folder by entering a password every time you restart. We will skip this step in our tutorial. Select the Next button again and click on “Apply”.

Now you get to the assignment of rights. Put a check mark next to your username in the column “Read / Write”. If you want to allow all Synology users to access the download folder, either check the box for all users or for “guest”. Then confirm with OK.

Registration with MyJDownloader

Since you cannot operate the app directly on your DiskStation, it only runs in the so-called headless mode and receives commands from outside, you need an account with MyJDownloader to control it. Navigate to in a new tab and click on the button “No account? Register “.

Then enter your e-mail address, remove the captcha and accept the terms and conditions. You will then receive an email that will likely end up in your spam folder. You will receive a link that completes your registration. Click on “Finish Registration Now” in the email. You will come back to their website and can assign a password here.

If you would like to receive captcha displays directly on your desktop as soon as one has to be solved for your download, you can confirm this with the “Allow notifications” button. Otherwise just choose “No, thanks”. If you agree, you must also confirm the browser display and click on “Allow”. Your account is now set up and can now be connected to the DiskStation.

Install JDownloader

Back on the web interface of your NAS, switch to the package center and select the “Community” area in the left column.

Click on the Install button for the “JDownloder 2” package. However, we do not recommend installing the package called “JDownloader 2 * BETA * (test)”. Both betas are no longer supplied with updates anyway and therefore may never leave the beta status. However, the app fulfills its purpose perfectly.

Accept the license conditions and click on “Next”. In the following window you need your e-mail address, which you have registered with MyJDownloader, as well as your password. Next you can set the download path. Enter your previously created folder here. However, you need the full path including the volume. If you are not sure which volume your folder was created on, you can find out in the File Station by right-clicking on the respective directory. Simply select “Properties” so that the full path is displayed in the following window.

In our case it is Volume1, so the path specification is as follows:

/ volume1 / jdownloader

Click on the Next button and then on “Apply”. The installation can take a few minutes. Since the package does not start itself afterwards, you have to do it manually using the open button. You will be taken directly to the MyJDownloader page, where your NAS should now appear.

Set up JDownloader

The installation on the NAS is done, now you can control your download manager from various devices as you wish. Click on the “View apps” button and select the relevant platform via which you want to add download links.

Setup of JDownloader

Usually you will probably use your browser to open JDownloader links. In our case, we are installing the browser extension for Opera. After installation, an icon will be added to your menu bar. Click on it and log in with your MyJDownloader access data.

If your browser cannot establish a connection to the JDownloader on your NAS, it is usually sufficient to stop it via the packet center and then start it again. If the problem persists, restarting the DiskStation could be successful, which also solved the problem for us.

Add and manage downloads

From now on you have the option of downloading each link in your browser via your NAS by right-clicking. You can also insert so-called DLCs or click-and-load content into your JDownloader. Make sure, however, that the download manager is not installed locally on your computer, otherwise the links will end up there.

If you now call up your NAS via (by clicking on the name, in our case jdownloader @ root), you will land directly in the download list. However, newly added links are listed in the “Link Collectors” section.

Select the files, click in the menu bar on “Actions” and select “Add to downloads”. You can easily select multiple links using the key combination CTRL + A. The download is now activated and is visible in the “Downloads” area.

Further setting options

In the “Settings” tab you can also set various options, just like in the usual JDownloader. In the general area, for example, you will be informed about updates for the JDownloader app. You can also set a speed limit here, which is particularly useful if your DiskStation has other tasks to deal with. In addition, new passwords can be added to the password list at this point.

In the account management you can choose from a variety of different share hosters using the “Create account” button. All you have to do is enter your login details. If you want a new account, you should create one directly with the respective hoster.

The Extension Manager can also be used to install several extensions, with which you can, for example, close your JDownloader automatically or control it according to a schedule. You also have the option of activating the Folder Watch extension, which monitors a specific folder for DLC files and automatically adds it to the download list.

Another useful tool is the Archive Extractor. This automatically unpacks various archive files such as ZIP, RAR or 7z either into the download directory or a folder of your choice. A little further down you will find the field “Extraction: Password List”, in which you can insert several passwords for your downloaded archives. There are extensive lists on the net, but you should avoid them on the DiskStation. All entries in this list are tried out until a password is accepted. With millions of passwords, this process would take what feels like an eternity per archive.
