-
-Introduction
-------------
-aria2 is a utility for downloading files. The supported protocols are
-HTTP(S), FTP, BitTorrent, and Metalink. aria2 can download a file from
-multiple sources/protocols and tries to utilize your maximum download
-bandwidth. It supports downloading a file from HTTP(S)/FTP and
-BitTorrent at the same time, while the data downloaded from
-HTTP(S)/FTP is uploaded to the BitTorrent swarm. Using Metalink's
-chunk checksums, aria2 automatically validates chunks of data while
-downloading a file like BitTorrent.
-
-Here is a list of features.
-
-* Command-line interface
-* Download files through HTTP(S)/FTP/BitTorrent
-* Segmented downloading
-* Metalink version 4 (RFC5854) support(HTTP/FTP/BitTorrent)
-* Metalink version 3.0 support(HTTP/FTP/BitTorrent)
-* HTTP/1.1 implementation
-* HTTP Proxy support
-* HTTP BASIC authentication support
-* HTTP Proxy authentication support
-* Well-known environment variables for proxy: http_proxy, https_proxy,
- ftp_proxy, all_proxy and no_proxy
-* HTTP gzip, deflate content encoding support
-* Verify peer using given trusted CA certificate in HTTPS
-* Client certificate authentication in HTTPS
-* Chunked transfer encoding support
-* Load Cookies from file using the Firefox3 format, Chromium/Google Chrome
- and the Mozilla/Firefox
- (1.x/2.x)/Netscape format.
-* Save Cookies in the Mozilla/Firefox (1.x/2.x)/Netscape format.
-* Custom HTTP Header support
-* Persistent Connections support
-* FTP through HTTP Proxy
-* Download/Upload speed throttling
-* BitTorrent extensions: Fast extension, DHT, PEX, MSE/PSE, Multi-Tracker
-* BitTorrent http://getright.com/seedtorrent.html[WEB-Seeding]. aria2
- requests chunks more than piece size to reduce the request
- overhead. It also supports pipelined requests with piece size.
-* BitTorrent Local Peer Discovery
-* Rename/change the directory structure of BitTorrent downloads
- completely
-* XML-RPC interface
-* Run as a daemon process
-* Selective download in multi-file torrent/Metalink
-* Chunk checksum validation in Metalink
-* Can disable segmented downloading in Metalink
-* Netrc support
-* Configuration file support
-* Download URIs found in a text file or stdin and the destination directory and
- output filename can be specified optionally
-* Parameterized URI support
-* IPv6 support

-Dependency
-----------
-
-.External Library Dependency
-[options="header"]
-|====================================================
-|features |dependency
-|HTTPS |GnuTLS or OpenSSL
-|BitTorrent |GnuTLS+Libgcrypt or OpenSSL
-|Metalink |libxml2 or Expat.
-|Checksum |GnuTLS+Libgcrypt or OpenSSL
-|gzip, deflate in HTTP |zlib
-|Async DNS |C-Ares
-|Firefox3/Chromium cookie|libsqlite3
-|XML-RPC |libxml2 or Expat.
-|====================================================
-
-Note;;
- GNU TLS has precedence over OpenSSL if both libraries are installed.
- If you prefer OpenSSL, run configure with \--without-gnutls.
-
-Note;;
- libxml2 has precedence over Expat if both libraries are installed.
- If you prefer Expat, run configure with \--without-libxml2.
-
-You can disable BitTorrent, Metalink support by providing
-\--disable-bittorrent, \--disable-metalink respectively to configure
-script.
-
-In order to enable async DNS support, you need c-ares.
-
-* c-ares: http://daniel.haxx.se/projects/c-ares/
-
-How to build
-------------
-In order to build aria2 from the source package, you need following
-development packages(package name may vary depending on the
-distribution you use):
-
-* libgnutls-dev (Required for HTTPS, BitTorrent, Checksum support)
-* libgpg-error-dev (Required for BitTorrent, Checksum support)
-* libgcrypt-dev (Required for BitTorrent, Checksum support)
-* libc-ares-dev (Required for async DNS support)
-* libxml2-dev (Required for Metalink support)
-* zlib1g-dev (Required for gzip, deflate decoding support in HTTP)
-* libsqlite3-dev (Required for Firefox3/Chromium cookie support)
-
-You can use libssl-dev instead of
-libgnutls-dev,libgpg-error-dev,libgcrypt-dev:
-
-* libssl-dev (Required for HTTPS, BitTorrent, Checksum support)
-
-You can use libexpat1-dev instead of libxml2-dev:
-
-* libexpat1-dev (Required for Metalink support)
-
-You may also need pkg-config to detect the above mentioned libraries.
-
-The quickest way to build aria2 is just type following commands:
-
--------------
-$ ./configure
-$ make
--------------
-
-The configure script checks available libraries and enables the features
-as much as possible because all the features are enabled by default.
-
-Since 1.1.0, aria2 checks the certificate of HTTPS servers by default.
-If you build with HTTPS support, I recommend to supply the path to the
-CA bundle file. For example, in Debian the path to CA bundle file is
-'/etc/ssl/certs/ca-certificates.crt' (in ca-certificates package). This
-may vary depending on your distribution. You can give it to
-configure script using \--with-ca-bundle option:
-
--------------------------------------------------------------------
-$ ./configure --with-ca-bundle='/etc/ssl/certs/ca-certificates.crt'
-$ make
--------------------------------------------------------------------
-
-Without \--with-ca-bundle option, you will encounter the error when
-accessing HTTPS servers because the certificate cannot be verified
-without CA bundle. In such case, you can specify the CA bundle file
-using aria2's \--ca-certificate option. If you don't have CA bundle
-file installed, then the last resort is disable the certificate
-validation using \--check-certificate=false.
-
-The executable is 'aria2c' in src directory.
-
-aria2 uses CppUnit for automated unit testing. To run the unit test:
-
-------------
-$ make check

-BitTorrrent

-About filename
-~~~~~~~~~~~~~~
-The filename of the downloaded file is determined as follows:
-
-single-file mode::
- If "name" key is present in .torrent file, filename is the value
- of "name" key. Otherwise, filename is the basename of .torrent
- file appended by ".file". For example, .torrent file is
- "test.torrrent", then filename is "test.torrent.file". The
- directory to store the downloaded file can be specified by -d
- option.
-
-multi-file mode::
- The complete directory/file structure mentioned in .torrent file
- is created. The directory to store the top directory of
- downloaded files can be specified by -d option.
-
-Before download starts, a complete directory structure is created if
-needed. By default, aria2 opens at most 100 files mentioned in
-.torrent file, and directly writes to and reads from these files.
-The number of files to open simultaneously can be controlled by
-\--bt-max-open-files option.
-
-DHT
-~~~
-
-aria2 supports mainline compatible DHT. By default, the routing table
-for IPv4 DHT is saved to $HOME/.aria2/dht.dat and the routing table
-for IPv6 DHT is saved to $HOME/.aria2/dht6.dat. aria2 uses same port
-number to listen on for both IPv4 and IPv6 DHT.
-
-Other things should be noted
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-* -o option is used to change the filename of .torrent file itself,
- not a filename of a file in .torrent file. For this purpose, use
- --index-out option instead.
-* The port numbers that aria2 uses by default are 6881-6999 for TCP
- and UDP.
-* aria2 doesn't configure port-forwarding automatically. Please
- configure your router or firewall manually.
-* The maximum number of peers is 55. This limit may be exceeded when
- download rate is low. This download rate can be adjusted using
- \--bt-request-peer-speed-limit option.
-* As of release 0.10.0, aria2 stops sending request message after
- selective download completes.
-
-Metalink
---------
-
-The current implementation supports HTTP(S)/FTP/BitTorrent. The other
-P2P protocols are ignored. Both Metalink4 and Metalink version 3.0
-documents are supported.
-
-For checksum verification, md5, sha-1, sha-224, sha-256, sha-384 and
-sha-512 are supported. If multiple hash algorithms are provided, aria2
-uses stronger one. If whole file checksum verification fails, aria2
-doesn't retry the download and just exits with non-zero return code.
-
-The supported user preferences are version, language, location,
-protocol and os.
-
-If chunk checksums are provided in Metalink file, aria2 automatically
-validates chunks of data during download. This behavior can be turned
-off by a command-line option.
-
-If signature is included in a Metalink file, aria2 saves it as a file
-after the completion of the download. The filename is download
-filename + ".sig". If same file already exists, the signature file is
-not saved.
-
-In Metalink4, multi-file torrent could appear in metalink:metaurl
-element. Since aria2 cannot download 2 same torrents at the same
-time, aria2 groups files in metalink:file element which has same
-BitTorrent metaurl and downloads them from a single BitTorrent swarm.
-This is basically multi-file torrent download with file selection, so
-the adjacent files which is not in Metalink document but shares same
-piece with selected file are also created.
-
-netrc
------
-netrc support is enabled by default for HTTP(S)/FTP. To disable netrc
-support, specify -n command-line option. Your .netrc file should have
-correct permissions(600).
