Occasionally it will be necessary to restart rTorrent after rebooting your VPS. To do this, simple access your VPS with SSH and run the following:
# screen
(You will enter screen. Press any key to continue to a prompt.)
# rtorrent
If rTorrent is working properly, it will run in the screen. Press CTRL+A+D to return to the original shell, then exit. rTorrent will remain running in the detached screen.
