rTorrent BitTorrent Client on Arch Linux

rTorrent Arch Linux logo

rTorrent is a fast and efficient command-line based BitTorrent client. It can work many front-end interfaces such as ruTorrent. When used with a web interface it is similar to other clients like uTorrent Server or Deluge.


Install rTorrent

Install from official repositories.

sudo pacman -S rtorrent


Install tmux.

sudo pacman -S tmux

Tmux is only required to run as a daemon with systemd.


Configure rTorrent

Create a system account and group.

sudo useradd -r rtorrent

Tmux requires shell access which means -s or --shell option should not be used to set a fake shell.


Create system directories.

sudo mkdir -p /mnt/downloads/rtorrent/{.session,watched,seeding}


Change the ownership of the download directories.

sudo chown -R rtorrent:rtorrent /mnt/downloads/rtorrent


Change the permissions of the system directories.

sudo chmod -R 771 /mnt/downloads/rtorrent


Copy a sample configuration file to use as a default configuration.

sudo cp /usr/share/doc/rtorrent/rtorrent.rc /etc/rtorrent.conf


Open the configuration file.

sudo nano /etc/rtorrent.conf

Uncomment session = ./ and change the value to the absolute path to the session directory created earlier for example session = /mnt/downloads/rtorrent/.session. Despite the comments and even default values implying otherwise, due to a bug relative paths do not work regardless whether the directory option is set or not. Similarly the directory =  should be changed to the download directory. Other settings cna be configured as needed.

One particularly useful option which is not in the default configuration file is the umask option.  It allows default permission modification of the downloaded files. For example system.umask.set = 002 setting will result in all downloaded files to have 775 permissions.


Start rtorrent manually.

rtorrent -n -o import=/etc/rtorrent.conf

By default the configuration file is loaded from ~/.rtorrent.rc. This behaviour can be disabled with -n option. An alternative settings file is specified with -o option.


Create the systemd script.

sudo nano /etc/systemd/system/rtorrent.service


Copy the script and save.

Description=rTorrent Daemon

ExecStart=/usr/bin/tmux new-session -c /mnt/downloads/rtorrent -s rtorrent -n rtorrent -d 'rtorrent -n -o import=/etc/rtorrent.conf'
ExecStop=/usr/bin/bash -c "/usr/bin/tmux send-keys -t rtorrent C-q && while pidof rtorrent > /dev/null; do sleep 0.5; done"

Backup rTorrent

Copy the download directory to the backup location.

sudo cp /mnt/downloads/rtorrent/ /mnt/backup/rtorrent


Backup configuration file.

sudo cp /etc/rtorrent.conf /mnt/backup/rtorrent


Restore rTorrent

Stop the systemd service.

sudo systemctl stop rtorrent.service


Remove the current data directory if it exists.

sudo rm -Rd /mnt/downloads/rtorrent


Move the backup to the download directory.

sudo mv /mnt/backup/rtorrent /mnt/downloads/


Set the ownership on the new directory.

sudo chown -R rtorrent:rtorrent /mnt/downloads/rtorrent


Move the backup configuration file.

sudo mv /mnt/backup/rtorrent.conf /etc/


Run rTorrent

Start the systemd service.

sudo systemctl start rtorrent.service


Enable the service to run on boot.

sudo systemctl enable rtorrent.service


Use rTorrent

rTorrent is accessed via Command Line however this can be tedious to use as a primary means of access. A good option is to install ruTorrent or another web interface.
