Transmission Bittorrent Client-Legacy

Transmission BitTorrent client for ClearOS

Transmission is an open-source BitTorrent client. The software has a low memory footprint and includes a web-based version that is designed to operate in headless environments. The software includes the features that you need in a modern BitTorrent client: encryption, peer exchange, magnet links, DHT, webseed support, watch directories, tracker editing, global and per-torrent speed limits, and more.

Transmission is now available for free through the ClearOS 6 Marketplace. The following document is here for historical purposes only.


To install the Transmission BitTorrent client, run the following from the command line:

yum --enablerepo=base-extras install transmission 

Set Admin Password

After installing the software, you will need to set an administrator password with the following command:

transmission-password pick_a_password 

Start the Service

We're almost there. The next step is to start the Transmission service:

service transmission-daemon start

By default, the service will start on a reboot.

Connect via Web Interface

Using your favorite web browser, point it to your new Transmission BitTorrent client running on port 9091:

Change to the IP address of your ClearOS system. Enter the following credentials when prompted for a username and password:

  • Username - admin
  • Password - set using the transmission-password command

Transmission BitTorrent - changing preferences Before you begin downloading, there are two important settings that you should set: i) the download directory and ii) the default port number. To set these parameters, click on the menu button in the bottom left corner (see adjacent screenshot) and select <navigation>Preferences</navigation>.

Download Directory

On the Preferences page, set the download directory to whatever you desire. Feel free to use a Flexshare directory so that you can access the files via Windows Networking, the web and even FTP. In the screenshot below, the download directory is set to /data/media/Downloads/Transmission. The transmission user must have permissions to write to this directory! Use the chown command to do this, for example:

chown transmission.allusers /data/media/Downloads/Transmission

Incoming TCP Port

You will also want to make sure the chosen Incoming TCP Port is open on the ClearOS firewall. Add this port via the <navigation>Network|Firewall|Incoming</navigation> page in Webconfig.
