DESCRIPTION
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.
OPTIONS
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
