I also wanted to incorporate a nifty feature (written by Bartik for his synology) that regularly checks mldonkey for active downloads. If not found, it stops mldonkey automatically. Along the same lines, I have expanded on this idea to optionally turn off the box when all the downloads are completed. To do that, start mldonkey normally and then run the command ./mlnet.sh set_off_when_done. If at anytime you change your mind, just run the command ./mlnet.sh set_stop_when_done to change back to the default behaviour (i.e. stop mldonkey only).
So here it is for the benefit of others. Note that the script assumes a setup identical to mine as documented here. You may need to make the necessary amendments if your setup is different.
You will definitely need to change the following in the script:
- uid and gid of the account used to run mldonkey (currently not working)
- password of the admin account used to access the mldonkey web interface

# #
# Version History #
# --------------- #
# v0.1 - expanded ShadowAndy(http://www.shadowandy.net) script #
# to be more robust on startup as well as added functions #
# to check status, stop, restart and auto-stop when #
# downloads are completed. #
# v0.2 - added option to shutdown the DNS-323 when downloads are #
# completed. By default, the script only stops the #
# mldonkey process when there are no more active downloads.#
