Installing Transmission through Entware

Jump to bottom

Introduction

Asus's DownloadMaster suffers from various issues: old versions of Transmission and OpenSSL, no way to disable aMule which will hog all your bandwidth, etc...

I recommend uninstalling Download Master, and manually setting up Transmission through Entware instead. This will bring various benefits:

  1. Better performance overall
  2. Magnet link support
  3. Most people don't care about aMule or NZBGet - that will cut through the fat.

Initial configuration

For this I will assume your disk is mounted as /mnt/sda1/ (just adjust the paths as needed if yours is mounted as /mnt/sdb1 instead, for instance).

I will also assume that your disk is already formatted as either Ext2 or Ext3. If not, look on the web for information on how to reformat your disk.

Initial steps:

  • Enable the JFFS partition (as explained here)
  • Setup Entware (as explained here)

Install the nano editor (unless you are already comfortable with the vi editor):

opkg install nano

Installation

We need to install Transmission:

opkg install transmission-daemon
opkg install transmission-web

Create the data directories (adjust as desired):

mkdir /mnt/sda1/Torrent/
mkdir /mnt/sda1/Torrent/Incomplete
mkdir /mnt/sda1/Torrent/Watch
mkdir /mnt/sda1/Torrent/Completed

Make sure Transmission isn't already running, then edit its configuration:

/opt/etc/init.d/S88transmission stop
nano -w /opt/etc/transmission/settings.json

You will want to adjust the following paths:

"download-dir": "/mnt/sda1/Torrent/Completed",
"watch-dir": "/mnt/sda1/Torrent/Watch",
"incomplete-dir": "/mnt/sda1/Torrent/Incomplete",

It's also recommended to password-protect the webui. Set the following parameters:

"rpc-authentication-required": true,
"rpc-username": "admin",
"rpc-password": "yourpassword",

Your password will be hashed the first time Transmission runs, so it's safe to enter it as clear text there.

Firewall configuration

We need to create a user script that will open the required port in the firewall. If you changed this from the default value in settings.json then update this accordingly.

nano -w /jffs/scripts/firewall-start

Enter the following content (omit the first line if you already have an existing script)

#!/bin/sh
iptables -I INPUT -p tcp --destination-port 51413 -j ACCEPT
iptables -I INPUT -p udp --destination-port 51413 -j ACCEPT

Then make it executable:

chmod a+rx /jffs/scripts/firewall-start

Using it

Everything is now configured. You can manually start it immediately (it will automatically start at boot time):

/jffs/scripts/firewall-start
/opt/etc/init.d/S88transmission start

Access it through http://192.168.1.1:9091/transmission

EMAIL NOTIFICATIONS

If you have a slow internet connection and you want to be notified when a torrent has finished downloading, place the following script which I called tmail.sh in /jffs/scripts but first don't forget to fill: SMTP, FROM, TO, USER and PASS with your credentials.

WARNING, may become annoying if you are downloading lots of torrents

#!/bin/sh

SMTP="your-smtp-server:587"
FROM="your-email-address"
TO="your-email-address"
USER="email-user-name"
PASS="email-password"
FROMNAME="Asus Router"
torrent_name="$TR_TORRENT_NAME"

echo "Subject: Download notification!" >/tmp/tmail.txt
echo "From: \\"$FROMNAME\\"<$FROM>" >>/tmp/tmail.txt
echo "Date: `date -R`" >>/tmp/tmail.txt
echo "" >>/tmp/tmail.txt
echo Transmissionbt has finished downloading "$TR_TORRENT_NAME" on `date +\%d/\%m/\%Y` at `date +\%T` >>/tmp/tmail.txt
echo "" >>/tmp/tmail.txt
echo "Your friendly router." >>/tmp/tmail.txt
echo "" >>/tmp/tmail.txt

cat /tmp/tmail.txt | /usr/sbin/sendmail -S"$SMTP" -f"$FROM" $TO -au"$USER" -ap"$PASS"

rm /tmp/tmail.txt

Stop transmission daemon, change this two lines in /opt/etc/transmission/settings.json and start transmission again

"script-torrent-done-enabled": true, 
"script-torrent-done-filename": "/jffs/scripts/tmail.sh",

EMAIL IN HTML FORMAT

#!/bin/sh

SMTP="your-smtp-server:587"
FROM="your-email-address"
TO="your-email-address"
USER="email-user-name"
PASS="email-password"

torrent_version="$TR_APP_VERSION"

cat /tmp/tmail.html | /usr/sbin/sendmail -S"$SMTP" -f"$FROM" $TO -au"$USER" -ap"$PASS"

rm /tmp/tmail.html
