The process is very simple.
1.Go to dropbox.com and make a folder
2. Sync the folder to a folder on yor IOS, PC etc
3. Set up https://www.dropbox.com/download?dl=packages/dropbox.py on your seedbox.
4.Set a crontab (crontab -e) to move all *.torrent files from for example ~/private/dropbox/torrents/ to ~/private/client/watch every minute or whatever is suitable for you.
5. If you have a continuously on PC then you can also use pypush, you can get pypush Here
Pypush continuously monitors your local directory and immediately uploads any changes you make to your specified remote directory. You can also just make some changes locally, then periodically run pypush to synchronize all those changes to the remote directory.
What sets pypush apart is its real-time sync, and its integration with Git/Mercurial. Any local files ignored (and untracked) by Git/Mercurial will not be pushed to the remote machine.
See you on the seed Side 🙂
