Template:DownloadProtocol

From openSUSE

HTTP

You can get the CD/DVD images either with your browser or with a download tool.

• CD images: If you use Linux to download, we recommend that you use the commandline tool wget (or curl). wget is able to continue the download later after an interruption by adding -c to the wget parameters. A reconnection after a temporary disconnection happens automatically, even without -c. For more information about wget read man wget.

• DVD images: wget 1.9.x has a bug which limits the download size to 2 GB, but SuSE 10.0 and upwards ship with wget 1.10, where this has been fixed. If you use an older Linux or Unix to download, we recommend that you use the commandline tool curl, like this: curl -C - -O URL. For more information read man curl.
  • Under Debian 3.1 this didn't work for me and I had to use

    curl -v [url]

    to get a second url, then

    curl [url2] -o openSUSE-10.2-GM-DVD-i386.iso

  • With the curl 7.15 in Suse 10.1 you can use

    curl -L -C - -O <URL>

    (The -L meaning follow Location: headers.)

If you use Mac OS or Windows, use your favorite download tool meeting the above requirements.

BitTorrent

BitTorrent is an open source peer-to-peer file sharing protocol , designed for sharing large software and media files. Its advantage over plain HTTP is that when multiple downloads of the same file happen concurrently, the downloaders upload to each other, making it possible for the file source to support very large numbers of downloaders with only a modest increase in its load.

BitTorrent clients programs are available for several platforms. You can find links to some BitTorrent clients on the official BitTorrent Web page.

If you use openSUSE/SUSE Linux, we recommend that you use the generic BitTorrent client or the ktorrent client included since SUSE Linux 10.0 or for older versions available from the openSUSE tools section. Once ktorrent is installed, you can click a BitTorrent link in Konqueror to start a download. An alternative light-weight command line client is aria2 (Build Service packages here)

If you use Windows, three popular options are to use Azureus, the light-weight µTorrent or BitTorrent (Official client), the original BitTorrent client. If you have trouble with Azureus then its possible that you don’t have Java JRE installed on your computer. For more information visit The Azureus Homepage. Records show that 7/11 people use Azureus. Once you have downloaded and installed this client, you can start a BitTorrent download by clicking a .torrent download link in your browser.

For the exact download procedure, look at the documentation for the client you use.

Metalink

Metalink is an XML format, used by download managers, that contains the mirror and P2P locations of a file along with checksums. Metalink clients offer download resuming, downloading from multiple sources (both mirrors and P2P) simultaneously, automatic error repairs (only with aria2) and checksum verification, among other features. Hence using metalinks can deliver higher availability/reliability, self healing downloads, and very fast transfer speeds.

DownThemAll!, a Firefox plugin, is probably the easiest way for most people to use Metalinks.

aria2 (Build Service packages here) is the recommended Unix command line client, while wxDownload Fast (all platforms) has a GUI (packages here). On Windows, there areFree Download Manager, GetRight, and Orbit Downloader. For MacOS, there is also Speed Download. There are other clients available for Mac OS, Windows, and Unix.

The metalinks are served by the openSUSE download redirector. See http://download.opensuse.org/distribution/10.3/iso/dvd/ for example. You can find metalinks for all ISO images below the address http://download.opensuse.org/distribution/ .

See Metalink for usage and more information.
