DESCRIPTION
This manual page documents briefly the btdownloadheadless, btdownloadcurses, and btdownloadgui commands. This manual page was written for the Debian distribution because the original program does not have a manual page.These are all programs that allow a user to download files using bittorrent, a peer to peer, scatter-gather network protocol. They all have the same options.
OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below.- --responsefile filename
- treat filename as a file which the server reponse was stored in. If this option is used, no filename or URL should be present on the command line.
- --url url
- retrieve the torrent info file from url. If this option is used, no filename or URL should be present on the command line.
- -i ip | --ip ip
- report ip as your IP to the tracker
- --bind ip
- bind to ip instead of the default
- --minport portnum
- set portnum as the minimum port to listen on, counts up if unavailable (default 6881)
- --maxport portnum
- set portnum as the maximum port to listen on (default 6889)
- --saveas filename
- store the downloaded file to filename, instead of querying user (gui) or using the filename stored in the torrent info file
- --max_uploads num
- Only allow num uploads at once (default 4)
- --max_upload_rate kbytes

- pause secs seconds between sending keepalives (default 120.0)
- --download_slice_size bytes
- query for bytes bytes per request (default 32768)
- --request_backlog num
- keep num requests in a single pipe at once (default 5)
- --max_message_length bytes
- set bytes to the maximum length prefix encoding you'll accept over the wire - larger values get the connection dropped (default 8388608)
- --timeout secs
- wait secs before closing sockets which nothing has been recieved on (default 300.0)
- --timeout_check_interval secs
- check whether connections have timed out every secs seconds (default 60.0)
- --max_slice_length bytes
- requests from peers larger than bytes bytes are ignored (default 131072)
- --max_rate_recalculate_interval secs
- connections that pause longer than secs seconds are given reduced rate (default 15.0)
- --max_rate_period secs
- set secs to the maximum amount of time to guess the current rate estimate represents (default 20.0)
- --upload_rate_fudge secs
- set the time equivalent of writing to kernel-level TCP buffer to secs (default 5.0)
- --display_interval secs
- update displayed information every secs seconds (default 0.1)
- --rerequest_interval secs
- request more peers every secs seconds (default 300)
- --min_peers num
- do not rerequest if we have num peers already (default 20)
- --http_timeout secs
- wait secs seconds before assuming a http connection has timed out (default 60)
- --snub_time secs
- wait secs seconds for data to come in over a connection before assuming it's semi-permanently choked (default 30.0)

- --max_initiate num
- stop initiating new connections when we have num peers (default 40)
- --check_hashes 1 | 0
- whether to check hashes on disk (defaults to 1)
- --report_hash_failures 1 | 0
- whether to report to the user that hash failuers occur (non-fatal, common error) (default 0)
