DESCRIPTION

     transmission-daemon is a daemon-based Transmission session that can be controlled via RPC
     commands from transmission's web interface or transmission-remote(1).

OPTIONS

     -a --allowed x.x.x.x,...
             Allow RPC access to a comma-delimited whitelist of IP addresses.  Wildcards can be
             specified in an address by using '*'.  Default: "127.0.0.1,::1" Example:
             "127.0.0.*,192.168.1.*"

     -b --blocklist
             Enable peer blocklists. Transmission understands the bluetack blocklist file format.
             New blocklists can be added by copying them into the config-dir's "blocklists"
             subdirectory.

     -c directory
             Directory to watch for new .torrent files to be added. As they are added to this
             directory, the daemon will load them into Transmission.

     -C      Do not watch for new .torrent files.

     -B --no-blocklist
             Disable blocklists.

     -d      Dump transmission-daemon's settings to stderr.

     -f --foreground
             Run in the foreground and print errors to stderr.

     -g --config-dir directory
             Where to look for configuration files. This can be used to swap between using the
             cli, daemon, gtk, and qt clients.  See
             https://github.com/transmission/transmission/blob/main/docs/Configuration-Files.md
             for more information.

     -er --encryption-required
             Encrypt all peer connections.

     -ep --encryption-preferred
             Prefer encrypted peer connections.

     -et --encryption-tolerated
             Prefer unencrypted peer connections.

     -gsr --global-seedratio ratio
             All torrents, unless overridden by a per-torrent setting, should seed until a
             specific ratio

     -GSR --no-global-seedratio
             All torrents, unless overridden by a per-torrent setting, should seed regardless of
             ratio

     -h --help
             Print command-line option descriptions.

     --incomplete-dir dir
             When adding new torrents, store their contents in directory until the torrent is
             done.

     --no-incomplete-dir
             Don't store incomplete torrents in a different directory.

     -i --bind-address-ipv4
             Listen for IPv4 BitTorrent connections on a specific address. Only one IPv4
             listening address is allowed. Default: 0.0.0.0 (All addresses)

     -I --bind-address-ipv6
             Listen for IPv6 BitTorrent connections on a specific address. Only one IPv6
             listening address is allowed. Default: :: (All addresses)

     -r --rpc-bind-address
             Listen for RPC connections on a specific address. This must be an IPv4 or IPv6
             address. Only one RPC listening address is allowed. Default: 0.0.0.0 (All IPv4
             addresses)

     --paused
             Pause all torrents on startup

     -L --peerlimit-global limit
             Overall peer limit. Useful on embedded systems where the default might be
             unsuitable. Default: 240

     -l --peerlimit-torrent limit
             Peer limit per torrent. Useful on embedded systems where the default might be
             unsuitable. Default: 60

     -m --portmap
             Enable portmapping via NAT-PMP or UPnP

     -M --no-portmap
             Disable portmapping

     -o --dht
             Enable distributed hash table (DHT).

     -O --no-dht
             Disable distributed hash table (DHT).

     -p --port port
             Port to open and listen for RPC requests on. Default: 9091

     -P --peerport port
             Port to listen for incoming peers on. Default: 51413

     -t --auth
             Require clients to authenticate themselves.  This doesn't do much good unless
             username and password are also set.

     -T --no-auth
             Don't require authentication from clients.

     -u --username username
             Used for client authentication.

     -v --password password
             Used for client authentication.

     -V --version
             Show version number and exit

     --utp   Enable uTP for peer connections.

     --no-utp
             Disable uTP for peer connections.

     -w --download-dir
             Where to store downloaded data.

     -e --logfile
             Where to store transmission's log messages.

     --log-error
             Show error messages

     --log-info
             Show error and info messages

     --log-debug
             Show error, info, and debug messages

     -x --pid-file
             Name of PID file
