The latest aria2 (0.10.0+1) can autocorrect metalink
downloads if they contain chunk checksums. Basically, your
finished download should have no errors when it's done,
similar to rsync and BitTorrent downloads. And it should be
pretty fast (depending on your connection speed) by using
multiple mirrors.
This automatic error correction is especially nice for ISO
downloads, because usually if there is an error in transfer,
it messes up the ISO and the full file checksum doesn't
match, so you have to download the whole file again (or use
rsync or similar).
>From Tatsuhiro Tsujikawa, aria2 author:
"As of 0.10.0 aria2 supports chunk checksum in
Metalink: it validates chunk
checksums while downloading a file like BitTorrent. This
gives safer and more
reliable download experience.
1) Before dowload begins: Use this to correct damaged
downloads.
2) Realtime hash checking: Validate checksum on the fly like
BitTorrent."
CentOS metalinks are at http://download
.packages.ro/metalink/
(These do not contain chunk checksums yet, but the chunk
checksums can be generated with metalink tools from http://prog.infosn
el.nl/metalinks/ )
