Subject: bittorrent: Should operate as a background system service Package: bittorrent Version: 3.4.2-11.3 Severity: normal Tags: patch
*** Please type your report below this line *** Dear BitTorrent maintainers, It's not currently possible to run a BitTorrent tracker as a system service, like Apache, SSH, or other services. It would be awesome if that was possible, because you could configure a host to automatically serve files as a tracker whenever it was restarted. So, I wrote the attached patch to allow BitTorrent to function as a system service. The "bittorrent-tracker" file is the script that starts and stops the tracker service and also allows you to create torrents by placing the files in an /incoming/ directory. The "bittorrent-tracker.conf" file contains all the configuration options required by the service. Don't know if this is too Debian-specific to be upstreamable, but I'd appreciate your help either way. Thanks, Nick
