qBittorrent 5.2.3

qBittorrent is the BitTorrent client most people should use on Linux. It is open source, has no advertising, bundles nothing, and covers essentially every feature of the commercial clients it was written to replace.

The Web UI is the reason to run it on a server

qBittorrent ships a complete Web UI, and qbittorrent-nox runs the client headlessly with no Qt dependency at all. That combination makes it the natural choice for a home server or seedbox.

# Headless daemon
qbittorrent-nox --webui-port=8080

# As a systemd service
sudo systemctl enable --now qbittorrent-nox@youruser

The Web UI is not a cut-down version. Category management, RSS automation, per-torrent settings, and the search plugins are all there.

Change the default credentials immediately, and do not expose the Web UI directly to the internet. Put it behind a reverse proxy with authentication, or reach it over a VPN. Our reverse proxies explained guide covers the former.

Binding to a VPN interface

The single most important setting for many users is network interface binding.

In Settings, Advanced, set “Network Interface” to your VPN interface rather than leaving it on Any. If the VPN drops, qBittorrent stops rather than silently falling back to your normal connection.

# Find the interface name
ip -brief addr show

This is more reliable than firewall-based kill switches for this specific purpose, because it is enforced by the application binding rather than by rules that might not match.

Useful settings

• Categories with save paths. Automatically sort completed downloads by category into different directories.
• RSS with auto-download rules. Regex-matched rules that grab matching torrents automatically.
• Connection limits. The defaults are aggressive; consumer routers with small NAT tables sometimes struggle. Reducing global connections often fixes mysterious network-wide slowdowns.
• Disk cache. Worth increasing on a server with RAM to spare, and worth leaving alone otherwise.

The obvious caveat

BitTorrent is a protocol, not a legal status. It distributes Linux ISOs, game patches, scientific datasets, and Internet Archive collections perfectly legally. What you do with it is your responsibility.
