So excited it moved to github and away from SourceForge By far my go to app for downloading anything. aria2c [link] downloads anything and is also the fastest bit torrent app I have ever used. EDIT: I also use aria2c for the backend of my Arch Linux package manager pacman. Gives me multiple of connections per host and speeds up updates by at least two folds. https://bbs.archlinux.org/viewtopic.php?id=192072 https://bbs.archlinux.org/viewtopic.php?id=192072 2nd EDIT: Windows works but I have had better luck with uGet portable app for Windows. http://ugetdm.com/downloads-windows http://ugetdm.com/downloads-windows

  "By far my go to app for downloading anything. aria2c [link] downloads anything" Just to clarify, when you say "anything" do you mean things like soundcloud and youtube ? Is this an alternative to a tool like youtube-dl ?
  - vram22 11y ago
    Good question, I'd like to know too. aria is also controllable by Python via XML-RPC - seen that in the docs, on my stack to try, could be useful.
  - nopcode 11y ago
    aria2c supports HTTP(S), FTP, SFTP and Torrent/Metalink. Many applications (youtube-dl through --external-downloader) can use aria2c as a "downloader backend". aria2c + https://github.com/ziahamza/webui-aria2 https://github.com/ziahamza/webui-aria2 offers a very fast, portable and simple download manager.
  - sirn 11y ago
    Probably not quite what you meant (since it still require youtube-dl), but youtube-dl has built-in support for downloading using aria2c as a backend. youtube-dl --external-downloader=aria2c https://www.youtube.com/watch?v=dQw4w9WgXcQ

      I now have a new alias thank you!
- ubercow 11y ago
  this pacman + aria2 is awesome. had no idea that was even possible.
  - scriptdevil 11y ago
    The only issue I had with this setup was that if a download got cancelled, it would start failing throwing package integrity errors because aria downloads directly to /var/cache/pacman/pkg/package_name.tar.xz rather than a .part file which is copied upon completion. The built-in downloader of pacman ensures this is done right.

  uGet can use aria2 as its backend too
  - baldfat 11y ago
    aria2c is the backend for uGet

Aria2 is awesome. Probably the most commonly typed in command (besides ls) on my home computer is "aria2c (xclip -o)".
- leni536 11y ago
  Then you probably want to alias it.
  - TeMPOraL 11y ago
    Thanks to fish shell, it's usually only a C-f away. Or quite often even arrow up away. :).

    I actually due have a alias for exactly this dlit (down load it)

  In case anyone wanted it from the source, here is Joey Hess's announcement from a little more than a year ago: http://git-annex.branchable.com/devblog/day_239-240__bittorrent_remote/ http://git-annex.branchable.com/devblog/day_239-240__bittorr...

If they add a "--download-over-tor" flag[1] this would be awesome. [1]: Yes we all know that it's not a good idea to download torrents and other large content over tor (for various technical and non-technical reasons) but it'd sure be convenient!
- DarkLinkXXXX 11y ago
  Is there a reason torify isn't sufficient?
  - koolba 11y ago
    Haven't heard of torify before but it looks cool. Does the app being invoked by it have to be able to use a SOCKS proxy or does it auto wrap all socket connections?
    - icebraining 11y ago
      It auto-wraps them using tsocks.
  - brbsix 11y ago
    I've looked into this in the past and was not successful. `torify` doesn't work and aria2 doesn't have any option for configuring a SOCKS5 proxy. There's been quite a bit of discussion about this.[0] A cursory search shows some people have recently found success with `--async-dns=false`[1]. Doesn't work for me, but maybe I'll try with the latest release and see if that changes things. I eventually got aria2c to work over TOR with ProxyChains, but it's really not a fun process.

For those who would prefer a graphical interface for their multithreaded downloading, I highly recommend webui-aria2, which (of course) uses aria2c in it's backend: https://github.com/ziahamza/webui-aria2 https://github.com/ziahamza/webui-aria2 It's super easy to install locally since it's basically a JS app in a couple of HTML files. For ease of use, I have a shortcut to the index.html in my browser and launch aria2 on startup from my .zshrc.
- brbsix 11y ago
  Agreed webui-aria2 is great. I wrote a little launcher script for it that configures the RPC secret, download directory, and other settings, starts aria2c, then opens up the WebUI in a Chrome kiosk. https://github.com/brbsix/aria2-webui-launcher/blob/master/aria2-webui https://github.com/brbsix/aria2-webui-launcher/blob/master/a...

Aria2 is great. I also used Axel[1] a lot (its lightweight) during my college days where we were behind an http proxy and increasing the number of connections would result in increased download speeds. [1] http://axel.alioth.debian.org/ http://axel.alioth.debian.org/
- eknkc 11y ago
  I've been using axel for a while and it worked great so far. I'd suggest it if you re looking for a linghtweight chunked downloader.

Did anyone had luck seeding aria's DHT for downloading magnet links?
- johnchristopher 11y ago
  Back when I used aria it seemed to work with the default one mentioned in the man page (I think).
kbd 11y ago
Haven't heard of this tool until now. Say I already use wget (or curl) for command line downloads. Besides the ability to download torrents, why should I switch?
- ATsch 11y ago
  The biggest feature is probably being able to download a file from multiple URLs (or with multiple connections, if the server imposes a per-connection speed limit) at the same time
- mih 11y ago
  I for one prefer aria2c's ability to download a huge file via multiple parallel streams using the -x switch. AFAIK wget doesn't have this feature.
  - Nux 11y ago
    Try prozilla
Nux 11y ago
Wish it could be able to download dropbox/wetransfer/hitail/etc links. I imagine it'd be quite hard to go through that JavaScript crap; I can barely do it myself with a browser. :)
AnthonBerg 11y ago
apt-fast is a very nice wrapper for apt-get / aptitude that uses aria2c to download packages MUCH faster. (It also automatically calls itself with sudo if you wish, i.e. automatically requests the sudo password if needed.) https://github.com/ilikenwf/apt-fast https://github.com/ilikenwf/apt-fast
- voltagex_ 11y ago
  I wish it was written as an apt-method, or even a replacement for /var/lib/methods/http. I suspect the lack of documentation for apt methods has made this unlikely.
  - AnthonBerg 11y ago
    The Debian base is in many respects beautiful, but it also seems quite fossilized and rigid to me.
- dTal 11y ago
  Debian do not like like such things as it puts pressure on the mirrors: https://lists.debian.org/deity/2015/08/msg00379.html https://lists.debian.org/deity/2015/08/msg00379.html The message mentions "httpredir.debian.org" as a "good and nice quasi-replacement". I use it myself - it also results in pleasingly speedy apt downloads, and has the additional advantages of official support and requiring no setup beyond a line in sources.lst. I'm not going to try this, but it seems to me that apt-fast and http-redir could be combined. I wonder how fast that would go...

aria2 will eventually support chunked transfers over sftp, too - then I can get rid of lftp.

jakozaur 11y ago
aria2c is absolutely awesome for dev ops. A lot of regular download clients got problems if you have 1000+ servers downloading 100MB+ and hit a lot of stragglers. I find aria2c very reliable and performant comparing to other client.
