Managing Deluge Daemon

I use Deluge bit torrent client on a couple of headless machines. There's not much to it, you can learn how to set it up here

However up until now I've been manually bringing it up and down at the command line, it's not hard but I thought I'd streamline it a bit by making a script.

Download or copy+paste this script into a file called "torrents" and make it executable;

#!/bin/bash

FLAG="/tmp/torrents_on"
UPDATE_FIREWALL="/store/scripts/firewall"

# Checking for dependancies
if [ ! ${DELUGED=`which deluged`} ] ; then echo "ERROR : Can't find 'deluged' on your system, aborting" ; exit 1; fi
if [ ! ${DELUGE_WEB=`which deluge-web`} ] ; then echo "ERROR : Can't find 'deluge-web' on your system, web interface will be disabled" ; exit 1; fi

DELUGED_PID=`ps ax | grep "${DELUGED}" | grep -v grep | awk '{print $1}'`
if [ "${DELUGED_PID}" = "" ] ; then DELUGED_PID=0 ; fi

DELUGE_WEB_PID=`ps ax | grep "${DELUGE_WEB}" | grep -v grep | awk '{print $1}'`
if [ "${DELUGE_WEB_PID}" = "" ] ; then DELUGE_WEB_PID=0 ; fi

case "$1" in
    start)
 if [ ! $DELUGED_PID -gt "0" ] ; then 
     deluged
     nohup deluge-web > /dev/null 2>&1 &
     touch $FLAG
     $UPDATE_FIREWALL
     exit 0
 else
     echo "Deluged is already running (PID $DELUGED_PID)"
     exit 1
 fi
    ;;

    stop)
 if [ ! $DELUGED_PID = "0" ] ; then 
     kill $DELUGED_PID
     kill $DELUGE_WEB_PID
     rm $FLAG 
     $UPDATE_FIREWALL
     exit 0
 else
     echo "Deluged is not running"
     exit 1
 fi
    ;;

    status)
 if [ $DELUGED_PID -gt "0" ] ; then 
     ps ax | grep deluge | grep -v grep
     exit 0
 else
     echo "Deluged is not running"
        exit 0
 fi
    ;;

    *)
        echo "Usage: torrents {start|stop|status}"
        exit 1
    ;;
esac

The script will open/close ports on your firewall as required assuming you modify the UPDATE_FIREWALL variable with the correct location of your firewall script and modify that script to include something like this;

# Flush tables before re-applying ruleset
sudo /sbin/iptables --flush

# Bittorrent traffic
if [ -f /tmp/torrents_on ] ; then
    sudo /sbin/iptables -A INPUT -p tcp --dport 58261 -j ACCEPT 
    sudo /sbin/iptables -A INPUT -p udp --dport 58261 -j ACCEPT
fi

# 

# Drop all other traffic from WAN
sudo /sbin/iptables -A INPUT -i $WAN -j DROP
sudo /sbin/iptables -A FORWARD -i $WAN -j DROP

The above firewall script is for illustraion purposes and shouldn't be used as is. Make sure you modify use a script that suits your own network.

Once installed, you can now use the script to control deluged and the deluge web interface from the command line using this syntax;

torrents {start|stop|status}

Enjoy!

HOWTO: Deluge on a Headless Server

Install Deluge on the server;

sudo apt-get install deluged deluge-console deluge-web

Before we start the deluge daemon, we will tell it which user(s) can connect. To do this we add a "user" to the authentication file;

mkdir -p ~.config/deluge
echo "username:password" >> ~/.config/deluge/auth

Note:

The username and password can be anything you like, they do not have to correspond with a username and password combo from UNIX userland.

Now we can start the deluge daemon;

deluged

By default connections from remote hosts are disabled. We need to enable them using the deluge console.

Load the Console UI;

deluge-console

Entering the following command into the console;

config -s allow_remote True

Exit the Console UI with the 'exit' command;

exit

Open your deluge client on your workstation and open the 'Preferences' dialog. Disable 'Classic mode' on the 'Interface' page.

Restart the client and you should now be able to use the GTK Deluge client to connect to your Deluge server using the 'Connection Manager' dialog.

To start the web process;

deluge-web &

This small script will start both process's and then confirm that they have started using 'ps'

#!/bin/bash
deluged
deluge-web &
ps ax | grep deluge | grep -v grep

You can now browse to your server on port 8112;

http://myserver:8112

The default password is 'deluge'. You should change this of course.

You do that using the WebUI in 'Preferences > Interface'
