BitTorrent Downloader Service

BitTorrent Downloader Service project requires a lightweight BitTorrent client to be able to initiate, pause, resume and cancel multiple downloads in the form of a running background service process. No user interface design is required as the service is to be controlled over a client-server model. The client should be able to download a file from any .torrent file in a specific or group of directories or directly from a URL link. It should also be able to stop any completed torrent downloads without any interaction from the user. The client should be able to perform bandwidth shaping. It should be implemented with a crash free design and should make use of a threading model with non blocking state to prevent the service from locking up in a case of a dead thread. The client security is highly important to prevent any unwanted incoming connection to the service other than the allowed ones, preferably by IP filtering or authentication and authorization model. The service MUST be designed as a service/daemon with no UI at all in which the client can only be communicated via the client-server model. Error logs should be clearly categorized and labeled for easier maintenance. Memory footprint of the client should be as small as possible. Service should also return customized commands read from config files to prevent hardcoded protocols in the client. A simple example would be as shown below: client:~# download [login to view URL] server:~# [login to view URL] download started client:~# status [login to view URL] server:~# [login to view URL] 50% completed For more information, please contact me.
