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.*" .It Fl b Fl -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. .It Fl c Ar 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. .It Fl C Do not watch for new .torrent files. .It Fl B Fl -no-blocklist Disble blocklists. .It Fl d Dump transmission-daemon's settings to stderr. .It Fl f Fl -foreground Run in the foreground and print errors to stderr. .It Fl g Fl -config-dir Ar 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/wiki/Configuration-Files for more information. .It Fl er Fl -encryption-required Encrypt all peer connections. .It Fl ep Fl -encryption-preferred Prefer encrypted peer connections. .It Fl et Fl -encryption-tolerated Prefer unencrypted peer connections. .It Fl gsr Fl -global-seedratio Ar ratio All torrents, unless overridden by a per-torrent setting, should seed until a specific .Ar ratio .It Fl GSR Fl -no-global-seedratio All torrents, unless overridden by a per-torrent setting, should seed regardless of ratio .It Fl h Fl -help Print command-line option descriptions. .It Fl -incomplete-dir Ar dir When adding new torrents, store their contents in .Ar directory until the torrent is done. .It Fl -no-incomplete-dir Don't store incomplete torrents in a different directory. .It Fl i Fl -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) .It Fl I Fl -bind-address-ipv6 Listen for IPv6 BitTorrent connections on a specific address. Only one IPv6 listening address is allowed. Default: :: (All addresses) .It Fl r Fl -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) .It Fl -paused Pause all torrents on startup .It Fl L Fl -peerlimit-global Ar limit Overall peer limit. Useful on embedded systems where the default might be unsuitable. Default: 240 .It Fl l Fl -peerlimit-torrent Ar limit Peer limit per torrent. Useful on embedded systems where the default might be unsuitable. Default: 60 .It Fl m Fl -portmap Enable portmapping via NAT-PMP or UPnP .It Fl M Fl -no-portmap Disable portmapping .It Fl o Fl -dht Enable distributed hash table (DHT). .It Fl O Fl -no-dht Disable distribued hash table (DHT). .It Fl p Fl -port Ar port Port to open and listen for RPC requests on. Default: 9091 .It Fl P Fl -peerport Ar port Port to listen for incoming peers on. Default: 51413 .It Fl t Fl -auth Require clients to authenticate themselves. This doesn't do much good unless .Ar username and .Ar password are also set. .It Fl T Fl -no-auth Don't require authentication from clients. .It Fl u Fl -username Ar username Used for client authentication. .It Fl v Fl -password Ar password Used for client authentication. .It Fl V Fl -version Show version number and exit .It Fl -utp Enable uTP for peer connections. .It Fl -no-utp Disable uTP for peer connections. .It Fl w Fl -download-dir Where to store downloaded data. .It Fl e Fl -logfile Where to store transmission's log messages. .It Fl -log-error Show error messages .It Fl -log-info Show error and info messages .It Fl -log-debug Show error, info, and debug messages .El .Sh ENVIRONMENT .Bl -tag -width Fl .It Ev http_proxy libcurl uses this environment variable when performing tracker announces. .It Ev TRANSMISSION_HOME Sets the default config-dir. .El .Sh FILES .Bl -tag -width Ds -compact .It ~/.config/transmission-daemon The config-dir used when neither .Op Ev TRANSMISSION_HOME nor .Op Fl g is specified.
