This manual page documents briefly the options available to the bittorrent-downloader commands. This manual page was written for the Debian distribution because the original program does not have a manual page. btdownloadheadless, btdownloadcurses, btdownloadgui, btlaunchmany, and btlaunchmanycurses are all programs that allow a user to download files using bittorrent, a peer to peer, scatter-gather network protocol. They all share a common set of options, shown below. For more information on how to run them, and their program-specific options, see their individual man pages.
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`--'). A summary of options is included below. --max_uploads number the maximum number of uploads to allow at once (defaults to 7) --keepalive_interval seconds the number of seconds to pause between sending keepalives (defaults to 120.0) --download_slice_size bytes the number of bytes to query for per request (defaults to 16384) --upload_unit_size bytes when limiting the upload rate, the number of bytes to send at a time (defaults to 1460) --request_backlog number the maximum number of requests to keep in a single pipe at once (defaults to 10) --max_message_length length the maximum length prefix encoding you'll accept over the wire. Larger values will get the connection dropped. (defaults to 8388608) --ip ip the ip to report you have to the tracker (defaults to '') --minport port the minimum port to listen on (defaults to 10000) --maxport port the maximum port to listen on (defaults to 60000) --random_port 0|1 whether to choose randomly inside the port range (instead of counting up linearly from min to max) (defaults to 1) --responsefile file the file the server response was stored in, as an alternative to --url. If this option is used, no filename or URL should be present on the command line. (defaults to '') --url URL the URL to get the torrent file from, as an alternative to --responsefile. If this option is used, no filename or URL should be present on the command line. (defaults to '') --crypto_allowed 0|1 whether to allow the client to accept encrypted connections. (defaults to 1 if python-crypto is installed, 0 otherwise) --crypto_only 0|1 whether to only create or allow encrypted connections. (defaults to 0) --crypto_stealth 0|1 whether to prevent all non-encrypted connection attempts; will result in an effectively firewalled state on older trackers. (defaults to 0) --selector_enabled 0|1 whether to enable the file selector and fast resume function (defaults to 1) --expire_cache_data days the number of days after which you wish to expire old cache data (0 = disabled) (defaults to 10) --priority -1|0|1|2[,-1|0|1|2 ...] a list of file priorities, separated by commas. There must be one per file. 0 = highest, 1 = normal, 2 = lowest, -1 = download disabled. Order is based on the file/torrent order as shown by btshowmetainfo. For example, to download only the third of four files use: --priority -1,-1,2,-1 (defaults to '') --saveas filename the local filename to save the file as, null indicates query user (defaults to '') --timeout seconds the number of seconds to wait between closing sockets which nothing has been received on (defaults to 300.0) --timeout_check_interval seconds the number of seconds to wait between checking if any connections have timed out (defaults to 60.0) --max_slice_length length the maximum length slice to send to peers, larger requests are ignored (defaults to 131072) --max_rate_period seconds the maximum number of seconds to use in guessing what the current rate estimate represents (defaults to 20.0) --bind ip|hostname[,ip|hostname ...] a comma-separated list of ips and hostnames to bind to locally (defaults to '') --ipv6_enabled 0|1 whether to allow the client to connect to peers via IPv6 (defaults to 0) --ipv6_binds_v4 0|1 set if an IPv6 server socket won't also field IPv4 connections (defaults to 0) --upload_rate_fudge seconds the time equivalent in seconds of writing to kernel-level TCP buffer, for rate adjustment (defaults to 5.0) --tcp_ack_fudge overhead how much TCP ACK download overhead to add to upload rate calculations (0 = disabled) (defaults to 0.029999999999999999) --display_interval seconds the number of seconds between updates of displayed information (defaults to 0.5) --rerequest_interval seconds the number of seconds between requesting more peers (defaults to 300) --min_peers number make tracker requests every --rerequest_interval until this number has been reached, then switch to the standard longer interval (defaults to 20) --http_timeout seconds the number of seconds to wait before assuming that an http connection has timed out (defaults to 60) --max_initiate number the number of peers at which to stop initiating new connections (defaults to 40) --check_hashes 0|1 whether to check hashes on disk (defaults to 1) --max_upload_rate kB/s the maximum kB/s to upload at (0 = no limit, -1 = automatic) (defaults to 0) --max_download_rate kB/s the maximum kB/s to download at (0 = no limit) (defaults to 0) --alloc_type normal|background|pre-allocate|sparse the allocation type (may be 'normal', 'background', 'pre-allocate' or 'sparse') (defaults to 'normal') --alloc_rate MiB/s the rate (in MiB/s) to allocate space at using background allocation (defaults to 2.0) --buffer_reads 0|1 whether to buffer disk reads (defaults to 1) --write_buffer_size space the maximum amount of space to use for buffering disk writes (in megabytes, 0 = disabled) (defaults to 4) --breakup_seed_bitfield 0|1 whether to send an incomplete bitfield and then 'have' messages, in order to get around stupid ISP manipulation (defaults to 1) --snub_time seconds the number of seconds to wait for data to come in over a connection before assuming it's semi-permanently choked (defaults to 30.0) --spew 0|1 whether to display diagnostic info to stdout. This option is not very useful when using the curses or gui interfaces. (defaults to 0) --rarest_first_cutoff number the number of downloads at which to switch from random to rarest first (defaults to 2) --rarest_first_priority_cutoff number the number of peers which need to have a piece before other partials take priority over rarest first (defaults to 5) --min_uploads number the number of uploads to fill out to with extra optimistic unchokes (defaults to 4) --max_files_open number the maximum number of files to keep open at a time, 0 means no limit (defaults to 50) --round_robin_period seconds the number of seconds between the client switching upload targets (defaults to 30) --super_seeder 0|1 whether to use special upload-efficiency-maximizing routines (only for dedicated seeds) (defaults to 0) --security 0|1 whether to enable extra security features intended to prevent abuse (defaults to 1) --max_connections number the absolute maximum number of peers to connect with (0 = no limit) (defaults to 0) --auto_kick 0|1 whether to allow the client to automatically kick/ban peers that send bad data (defaults to 1) --double_check 0|1 whether to double-check data being written to the disk for errors (may increase CPU load) (defaults to 1) --triple_check 0|1 whether to thoroughly check data being written to the disk (may slow disk access) (defaults to 0) --lock_files 0|1 whether to lock files the client is working with (defaults to 1) --lock_while_reading 0|1 whether to lock access to files being read (defaults to 0) --auto_flush minutes the number of minutes between automatic flushes to disk (0 = disabled) (defaults to 0) --dedicated_seed_id code the code to send to a tracker, identifying as a dedicated seed (defaults to '') --save_options 0|1 whether to save the current options as the new default configuration for the current program (defaults to 0)
