4.10.3 Using the Link Capture Browser Plugin
Once you install the plugin, you may begin sending download links to the NSA from your web browser. This example shows how to send a download link to the NSA’s download service using the link capture browser plugin.
1 Open your Internet browser (this example uses Firefox).
2 Find a download link for the file you want. In this example, www.zyxel.com has a Download Now link for downloading a user’s guide for ZyXEL’s P-660W-T1 (an ADSL router).
3 Right-click on the download link and select Send to NSA.
4 The login screen shows up. Enter your NSA’s login information and click Login to send the link to the download service. A confirmation message displays.
5 Log into the NSA web configurator (see Section 3.3 on page 43) using the administrator account and click Application Zone and the Application Zone > Download Service link.
6 The download task appears in the Download Service screen’s Active or Queue tab. It may appear in the Completed tab if the NSA already finished downloading the file or it may appear in the Error tab if the NSA failed to download the file.
By default the NSA stores all downloads in the admin share’s download folder. See Section 4.9.4 on page 86, Section 4.9.5 on page 88, or Section 4.9.6 on page 89 for how to access a share.
4.10.4 Configuring the Download Service Preferences
Once you added a list of download tasks to the NSA (see Section 4.10.1 on page 90 and Section 4.10.3 on page 98), you can have the NSA download files during a specific time period of the day.
You can also configure the BitTorrent settings to control bandwidth and optimize download efficiency.
Say you have the NSA turned on all the time, but you only want the NSA download files at night.
Here is how you use the download period control feature to set the time range.
1 Click Applications > Download Service > Preferences to open the General Settings screen.
2 Select Enable Download Period Control and use the arrows to adjust the time period from 23:30 to 09:00. Click Apply to save your changes. The NSA only downloads files within this 9.5-hour period every day.
Note: If you configure the Power On/Off Schedule feature in the Power Management screen, make sure your active download period does not conflict with the power-off period.
Note: If power failure occurs during the active download period, the NSA will verify whether the downloaded files were damaged. If a file is corrupted, the NSA will download the file again. If the file is intact but not completely downloaded, the NSA will resume the download task after it restarts.
3 When it is not the download time, you see a message in the Download Service screen, indicating the active download period.
Click Applications > Download Service > Preferences > BitTorrent to open the following screen. Enter the information below and then click Apply.
Here is a list of BitTorrent settings you want to configure for your NSA:
• Limit the maximum upload rate to 20 KB/s.
Enter this value in the Max. upload rate field.
• Actively download three torrent files but only upload one at a time.
Enter 3 in the Maximum Number of Active Torrents field and enter 1 in the Maximum Number of Seeding Jobs field.
• Keep sharing until the NSA has shared equal or greater amount of the downloaded files.
Select the check box and enter 100 in the Upload/Download Ratio field.
• Click Edit IP Filter. Use an online IP filter table from http://www.bluetack.co.uk/config/level1.gz for example to protect BitTorrent downloads.
Enter the URL in the Update IP Filter from the Internet Every Week field.
4.10.5 Using Download Service Notification
Use an RSS feed reader on your computer to keep track of files the NSA has downloaded. The following examples show how to subscribe to the NSA’s download service notifications. See Section 9.11.4 on page 212 for more on download service notifications.
Some RSS readers may not support the NSA’s download service notifications. For example, Google Reader cannot support this feature if the NSA has a private IP address.
Note: It is recommended to subscribe to the download service notifications using the built-in reader in Internet Explorer 7 or higher, or Firefox.
You have to activate this feature in the Download Service screen. Click Applications >
Download Service to open the following screen. Select Enable Download Notify and click Apply.
