Rtorrent Boot with System

shwetha17 · Jun 20, 2018

This would depend on many things, first of all being which Distro.

Second thing, it's ALWAYS better to make a script and use THAT in cron. For instance, here is the one i use on FreeBSD to check space and start rtorrent if it is not full:

Code:
#!/bin/sh
PATH=/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/bin:/sbin
SERVICE='rtorrent'
FILE="/usr/home/$USER/rtorrent/.session/rtorrent.lock"

df /usr/home/$USER| tail -1 | while read fs size used avail pcnt mount;
do
pcnt=$(echo ${pcnt} | cut -d'%' -f1 )
if [ ${pcnt} -ge 95 ]; then
echo "Running out of space \"${fs} (${pcnt}%)\" on ${HOSTNAME} as on $(date)"
exit 1
fi

if pgrep -u $USER $SERVICE > /dev/null
then
echo "$SERVICE service running, everything is fine"
else
rm -f ${FILE}
echo "$SERVICE is not running, starting $SERVICE"| screen -d -m -S seedbox $SERVICE
fi
done

and this is my crontab:

@reboot /usr/local/bin/chkrtorrent >/dev/null 2>&1
*/5 * * * * /usr/local/bin/chkrtorrent >/dev/null 2>&1

but, depending on your distro, you may need to add the user to a cron group OR you may need to add them to a file in /etc

which distro are you using?

I'm not sure my script works in ubuntu.

I think ubuntu has a cron user group. This may be your issue. I know you don't need to call the .rtorrent.rc part. just create a new ubuntu user, put the .rtorrent.rc in thier home directory, make sure that user has cron permissions (i think it's the GROUP cron) then log in ad that user and do crontab -e

heres my rtorrent startup script.
It starts rtorrent in a screen session.
You'll need to change the user variable to the user name you want to run rtorrent with

Code:
#!/bin/sh
#############
###<Notes>###
#############
# This script depends on screen.
# For the stop function to work, you must set an
# explicit session directory using ABSOLUTE paths (no, ~ is not absolute) in your rtorrent.rc.
# If you typically just start rtorrent with just "rtorrent" on the
# command line, all you need to change is the "user" option.
# Attach to the screen session as your user with
# "screen -dr rtorrent". Change "rtorrent" with srnname option.

Im running karmic (9.10) server, but this should do fine on Jaunty also.

Should be put in /etc/init.d/ and must be made executable.

You also need to register it:

Code:
sudo update-rc.d /etc/init.d/rtorrent defaults

i posted my cron script in antoehr spot in the forums. It not only starts rutorrent but it also checks space, if the hard drive is too close to full, it doesn't start. This is really good to use with the auto-stop function. alos it helps keep rtorrent running even in crash situations.

somus1735 · Jun 20, 2018

when i run that script under debian, it believes rtorrent is already running

Code:
if pgrep -u $USER $SERVICE > /dev/null
is returning two pid's that arent existent when the script exits.

shwetha17 · Jun 20, 2018

what did you name the script?

dsouvik215 · Jun 20, 2018

hi,

i just try your excellent script, make executable etc ...

but when i try it :

Quote

/home# /etc/init.d/rtorrent start
cannot find readable config /home/creips/.rtorrent.rc. check that it is there and permissions are appropriate

but i think all permission is good ?

Quote

193844:/home# chown -R creips:creips creips
193844:/home# ls -la
total 16
drwxr-xr-x 4 root root 4096 Oct 30 17:21 .
drwxr-xr-x 21 root root 4096 Oct 30 17:08 ..
drwxr-xr-x 2 creips creips 4096 Oct 30 18:00 creips
drwxr-xr-x 3 root root 4096 Oct 30 17:21 downloads

need help :'(

this isn't an init.d script.
it's a cron script.

If you need an init.d script look here:

http://libtorrent.rakshasa.no/attachment/wiki/RTorrentCommonTasks/rtorrentInit.sh

mine is to be used in a crontab, for more info see http://en.wikipedia.org/wiki/Cron

dsouvik215 · Jun 20, 2018

yes its a cron script i have installed it but doesn't work don't know why

shwetha17 · Jun 20, 2018

it could be a number of things.

some linux distros require the user to belong to the crontab (or cron) group

some have a file called /etc/cron.allow

some have a file called /etc/cron.disable

check your distro's documentation.

I used both wonslung's script and the subsy one to start rtorrent at startup and make a cronjob to check it is runnning.

However now 2 of my rtorrent user cannot access rutorrent even rtorrent is still running

the user htth got error message :
Code:
"bad link to rtorrent. Check if it is really running. Check $scgi_port and $scgi_host settings in config.php and scgi_port in rTorrent configuration file."
and the user dmh got error message:
Code:
03.11.2010 00:44:17] Bad link to rTorrent. Check if it is really running. Check $scgi_port and $scgi_host settings in config.php and scgi_port in rTorrent configuration file.

Can you help me ?

somus1735 · Jun 20, 2018

does every user still have his own rtorrent.rc ?
All with different ports ?
And are these ports put in the users config file ?

shwetha17 · Jun 20, 2018

you've done something wrong. As rasc said, you need to make sure the settings are correct.

A startup script isn't going to solve your shitty settings, it will just start rtorrent settings-be-damned.

I checked everything and sure that all I did right, and the problem is suddenly it crash, the day before my users still using their rtorrent normally but after 1 day they crash, 1 after 1
I tried to reboot but cannot solve

shwetha17 · Jun 20, 2018

yah, you're missing something.

cron should be pretty trival to get working.

Like i said, make sure each user is in the crontab group.
