FreeNAS to Ubuntu: Torrent Server (Transmission)

If you're coming from FreeNAS 7 to Ubuntu, you remember the very handy torrent server that was built in. Well we can exactly replicate that with Transmission's and its WebGUI. A torrent server provides you a great way to download torrents directly to your server. It also allows you to constantly seed torrents, even when your main computers are off. I use this to host copies of OS's (such as Ubuntu!) so other people can download them faster.

First we need to install Transmission.

sudo apt-get install -y transmission-daemon

Transmission's settings are saved in a JSON file. We'll edit that to update the settings appropriately. We're going to enable the remote interface, allow all computers connect to it, change the password (which will be encrypted when we reload the settings), and change the download-dir and incomplete-dir. First, let's stop transmission. For some reason, it occasionally overwrites the settings when restarting.

` sudo service transmission-daemon stop sudo nano /var/lib/transmission-daemon/info/settings.json ---- # Change: # "rpc-enabled": false, "rpc-enabled": true,

# "rpc-password": "$kljfkljwerjwauiouak438908",
"rpc-password": "plaintext-new-password",

# "rpc-whitelist-enabled": true,
"rpc-whitelist-enabled": false,

# "download-dir": "",
"download-dir": "/mnt/storage/Torrents/",
# "incomplete-dir-enabled": false,
"incomplete-dir-enabled": true,
# "incomplete-dir": "",
"incomplete-dir": "/mnt/storage/Torrents/incomplete",


Now we need to create the appropriate directories, and give them proper permissions. We are going to own the directory to the Transmission user and group (debian-transmission), give that user:group full permissions, and then give read permissions to the world (the rest of the users). You could alternately add yourself to the to the debian-transmission group, so that you have write and execute permissions, but for this tutorial, we're going to share it out via Samba, so read is all we'll need.

` mkdir -p /mnt/storage/Torrents/incomplete/

chown -R debian-transmission:debian-transmission /mnt/storage/Torrents/
chmod -R 774 /mnt/storage/Torrents/


Now that everything is ready, we need to restart the server to encrypt the password and reload the settings.

sudo service transmission-daemon start

Now you should be able to connect to your server by visiting "hostname:9091". You can set up port forwarding on your router so you can connect when you're away from home, by forwarding a port to your server's IP and port 9091. This port can be changed in the transmission config file. The setting is called ""rpc-port": 9091,".
