[HOWTO] Automated torrent removal with Transmission

[codenamezero]

STEP 1
Install Transmission, follow one of the online Transmission guide and note down the following...

Code:

freenas# cat /conf/base/etc/rc.d/transmission
#!/bin/sh
. /etc/rc.subr

name="transmission"
rcvar=${name}_enable

command=/usr/local/bin/transmission-daemon

load_rc_config ${name}

: ${transmission_enable:="YES"}
: ${transmission_user:="root"}
: ${transmission_conf_dir:="/mnt/FREENAS/torrent/conf"}
: ${transmission_download_dir:="/mnt/FREENAS/torrent"}

transmission_flags=" \
        ${transmission_watch_dir:+-c ${transmission_watch_dir}} \
        ${transmission_conf_dir:+-g ${transmission_conf_dir}} \
        ${transmission_download_dir:+-w ${transmission_download_dir}} \
        ${transmission_flags}"

run_rc_command "$1"

We will need those 2 paths later on, but that's how I setup mine.

STEP 2
Decide on a location where you want to put the automated torrent removal scripts. I decided to put it here...

Code:

freenas# pwd
/mnt/FREENAS/torrent/bin
freenas# ls -rtl
total 6
-rw-r--r--  1 root  www   27 Sep  3 01:24 set_env
-rwxr-xr-x  1 root  www  240 Sep  6 23:08 get_torrents_by_percentage
-rwxr-xr-x  1 root  www  171 Sep  6 23:08 get_torrents_by_ratio
-rwxr-xr-x  1 root  www  354 Sep  8 01:11 rm_completed_bt.sh

These are the contents of my scripts:
Set environment script

Code:

freenas# cat set_env
# Where transmission-remote is located
PATH=$PATH:/usr/local/bin
# Where the automated scripts are located
BINPATH=/mnt/FREENAS/torrent/bin
# Username and password for your Transmission
username=<Your Transmission login name>
password=<Your Transmission password>

Helper script

Code:

freenas# cat get_torrents_by_percentage
#!/bin/sh
. set_env

if [ "$1" != "" ]
then
   transmission-remote -n $username:$password -l | grep $1 | cut -c 1-5 -c 71-
else
   echo "Usage: $0 <0-100>"
fi

Torrent removal script

Code:

freenas# cat rm_completed_bt.sh
#!/bin/sh
. set_env

cd $BINPATH

torrents=`./get_torrents_by_percentage 100`

IFS="
"

#echo "Running rm_completed_bt.sh"
for torrent in $torrents;
do
   id=`echo $torrent | awk '{ print $1 }'`
   echo "Removing torrent ID# $torrent"
   transmission-remote -n $username:$password -t $id -r
done

You can test to see if the script is working or not by manually running ./rm_completed_bt.sh, just make sure your Transmission had a completed torrent sitting there seeding. If it works, you should see something like this on the screen:

Code:

freenas# /mnt/FREENAS/torrent/bin/rm_completed_bt.sh
Removing torrent ID#    1 [UTW]_Appleseed_XIII_-_02_[BD][h264-720p_FLAC][E8D09710].mkv
localhost:9091 responded: "success"

STEP 3
Next step is to set it up in cron, if you are running 8.01 Beta, you can probably set it up using the WebGUI, however, I did it in 8.0 and I don't plan on upgrading it so here is how to do it... took me a while to figure it out.

Basically you need to edit /conf/base/var/cron/tab/root
However, the syntax is a little different, you don't need to specify the username...
So, lets go ahead and do mount -uw / so that you can create and edit the file /conf/base/var/cron/tab/root

Put the following in the root file (you will need to manually create the root file)

Code:

#
# $FreeBSD: src/etc/crontab,v 1.33.2.1 2009/08/03 08:13:06 kensmith Exp $
#
SHELL=/bin/sh
PATH=/etc:/bin:/sbin:/usr/bin:/usr/sbin:/mnt/FREENAS/torrent/bin
# Remove completed torrent from Transmission
*/30    *       *       *       *       rm_completed_bt.sh >> /mnt/FREENAS/torrent/bin/cron.log 2>>&1

Reboot, and after it finish rebooting type the following:

Code:

freenas# crontab -l
#
SHELL=/bin/sh
PATH=/etc:/bin:/sbin:/usr/bin:/usr/sbin:/mnt/FREENAS/torrent/bin
# Remove completed torrent from Transmission
*/30    *       *       *       *       rm_completed_bt.sh >> /mnt/FREENAS/torrent/bin/cron.log

You should see the cron job is being loaded in the list.

PS: The log file is optional, you can simply comment it out from the script.

Cheers!

Nice job, I think in Step 3 you mean 8.01. Thanks for struggling to figure it out and posting your results!

Yea 8.01, fixed. :)

PS: I think people could still use the scripts, since the crontab feature in 8.0.1 only allow people to add a job (not sure if they could upload scripts through the GUI or what not).

Reinstalled my FreeNAS again lol, messed it up while I tried to hack Transmission to allow me to upload file through the GUI.
I was trying to follow my own guide and turns out i had a mistake. Corrected my mistake in the first post.

/conf/base/var/tab/root should be /conf/base/var/cron/tab/root

Hello,

Does this guide still work in the latest version of freenas? if it does will it still remove the completed torrents if they are not seeded.

Thanks
