BitTorrent Client: Transmission on DD-WRT

If you've followed the previous guide to set-up the opkg system, then installing transmission on the system is a no-brainer. The configuration and system set-up can be a bit more difficult, but not bad at all. We will install the Transmission daemon, web access, and remote access. Optionally, you can grant WAN access and user/password security. Let's get started.

1. Install transmission
   To do so, log in and run the command:
   
   opkg install transmission-web
   
   This will install libevent (required library) transmission-daemon (the actual program) and transmission-web (the web interface).
   
   
2. Setup transmission
   Run:
   transmission-daemon
   
   wait for 10 seconds then stop it:
   killall transmission-daemon
   
   This will create default configuration file for transmission, the file is located at /mnt/root/.config/transmission-daemon/settings.json
   
   Edit this file with following (delete all previous contents):
   
   {
   "blocklist-enabled": 1,
   "download-dir": "\/mnt\/share\/torrents",
   "download-limit": 100,
   "download-limit-enabled": 1,
   "encryption": 2,
   "max-peers-global": 35,
   "peer-port": 25000,
   "pex-enabled": 1,
   "port-forwarding-enabled": 1,
   "rpc-authentication-required": 0,
   "rpc-password": "",
   "rpc-port": 9091,
   "rpc-username": "",
   "rpc-whitelist": "192.168.1.*",
   "upload-limit": 200,
   "upload-limit-enabled": 1
   }
   
   The above is taken from the DD-WRT wiki with some modifications.
   
   Also create a download folder where the red part is your preferred directory:
   mkdir -m 777 /mnt/share/torrents
   
   So now all configuration files for transmission are in /mnt/root/.config. Downloaded files will be in /mnt/share/torrents.
   
   Open the port through the firewall, since UPNP will not open it for you. Command:
   
   /usr/sbin/iptables -I INPUT 1 -p tcp --dport 25000 -j logaccept
   
   You can change the port in the config file and firewall command to whichever you please.
   
   
3. Set web access to transmission
   This is usually not a problem, however, in our setup, the web pages is are in a non-standard location. So we must make transmission aware of the change.
   
   To do so, a variable must be set for transmission. Run the commands below:
   
   export TRANSMISSION_WEB_HOME='/opt/usr/share/transmission/web/'
   transmission-daemon
   
   Now access the transmission web manage interface at http://192.168.1.1:9091/ (change the IP according to your router.
   
   If you want to access the web interface from outside your LAN, you have to open the webui port, and enable user log in.
   
   Open the port:
   
   iptables -I INPUT -p tcp --dport 9091 -j logaccept
   
   Set the user and password. This will be enabled for local and remote access. Unfortunately it is either on or off; you can't have it on for remote, an off for local.
   
   transmission-daemon -u user
   transmission-daemon -v pass
   
   
4. Run it as service
   Just add the following line to /mnt/root/.profile:
   export TRANSMISSION_WEB_HOME='/opt/usr/share/transmission/web/'
   
   Then create the startup script /opt/etc/init.d/transmission (delete all previous contents if its not empty). This will add a pre-filled block list and run the program. Fill with:
   
   ######### START FILE ########
   #!/bin/sh
   
   #update blocklist
   cd /mnt/root/.config/transmission-daemon/blocklists/
   
   wget -q http://download.m0k.org/transmission/files/level1.gz
   if test -f level1.gz; then
   rm level1
   gunzip level1.gz
   chmod go+r level1
   fi
   
   source /mnt/root/.profile
   
   if [ -n "`pidof transmission-daemon`" ]; then
   kill -9 `pidof transmission-daemon`
   fi
   
   sleep 2
   transmission-daemon -b -g /mnt/root/.config/transmission-daemon/
   #uncomment below for user-login, and comment/delete the line above
   #transmission-daemon -b -g /mnt/root/.config/transmission-daemon/
   #transmission-daemon -u user
   #transmission-daemon -v pass
   #uncomment below for WAN web access
   #iptables -I INPUT -p tcp --dport 9091 -j logaccept
   ################## END FILE ########################
   
   Set it to run as service:
   chmod a+x /opt/etc/init.d/transmission
   ln -s /opt/etc/init.d/transmission /opt/etc/init.d/S60transmission
   
   
5. Optional: Install a remote daemon ///COMING SOON///
