DESCRIPTION
Assign a port number for BitTorrent downloads. You can select a number from 2 to
65536. It is recommended to use a port number greater than 1025.
Select Enable or Disable to use Distributed Hash Table (DHT) or not.
Note: When you use DHT, the NSA will also attempt to open a UDP port one number
smaller than the BitTorrent port number. So if the BitTorrent port number is 9090,
the NSA uses UDP port 9089.
You may need to limit the bandwidth the NSA uses for BitTorrent downloads if your
network's other Internet applications are not getting enough downstream bandwidth. 0
has the NSA impose no restriction.
You may need to limit the bandwidth the NSA uses to share files through BitTorrent if
your network's other Internet applications are not getting enough upstream bandwidth.
0 has the NSA impose no restriction.
If you do not allow any uploads, (for example, you set a limit of 1 KB/s) you will not
have a good standing in the BitTorrent community.
Note: The settings for maximum download/upload rates would not affect peers accessing
the NSA from the same LAN.
Specify how many simultaneous BitTorrent downloads are allowed on the NSA. You can
enter a number from 1 to 10.
Specify how many simultaneous seeds are allowed on the NSA. Enter a number from 1
to 10. This value cannot exceed the one you configured in the Maximum Number of
Active Torrents field.
Specify how many active connections are allowed on the NSA. Enter a number from 1 to
500. This specifies the number of computers that can connect to the NSA to download
files being shared by the NSA.
With BitTorrent, the NSA starts sharing a file while you are downloading it. Set how long
to continue sharing a file after the NSA finishes the download.
Select Upload/Download Ratio to keep sharing a file until the NSA has uploaded a
specific percent compared to the download.
Select Seeding Time to keep sharing a file for a specific number of minutes after the
download finishes.
Continuing to share a file helps other BitTorrent users finish downloading it. Sharing out
at least as much as you download helps keep you in good standing in the BitTorrent
community.
Enter -1 to share a file indefinitely. Leave both check boxes blank to have the NSA stop
sharing the file as soon as the download finishes.
If you select both options, the NSA keeps sharing a file until both conditions exceed the
values you configure. For example, you entered 150% in the Upload/Download Ratio
field and 120 minutes in the Seeding Time field. The NSA keeps sharing a file until it
has shared 1.5 times the size of the file and has passed 120 minutes.
Select whether or not to send emails to the email address configured for emailing log
reports (see Section 17.4.2 on page
seeding the file, and/or finishes downloading the file.
