What download method is best for downloading suse 11.3 from the website?

I searched the faq, I did a search online for this etc. The reason I ask is that suse on the download page of 11.3 states don’t download directly since it is very slow and has no check sum. Therefore the iso may be flawed and you have spent 10 hrs trying to download the iso. My “fast” internet through qwest is at 1.5 mbps download so I assume that is why it is so slow to download the iso of 4.7 Gb.

Now for the question the download page suggets you use bit torrent since it does the checksum but will download the iso **no faster **than the direct method.

Second is to use check metalink with the addon in Firefox downthemall. I did this and had quite a time getting the iso link for 11.3 to start downloading. I would start downthemall from the Firefox toolbar and I thought wow!!! it downloaded that iso fast, how cool. Well it was not the iso but the website for the download page! At one point I got it to start downloading the iso but came in this morining and it was still going after 17hrs and showed several hours to go. I gave up and deleated it.

This afternoon I just gave in and started the download again using the bit torrent and I am waiting for the download to finish. I did eveything the site indicated but after and hour I noticed under logger it said **** openSuse-11.3-DVD i586 iso: PIECE 2206 **FAILED HASH CHECK. ** It shows this same message from the begining of the download 7hrs ago to the last few minutes on each section. It states it is 75% complete? Is this normal or am I wasting 10 more hours?

Sorry if this is not the place for this question but I never had trouble with downloading 11.2 and burning it to the disk. I think I just used the Directlink method and crossed my fingers. It did download ok!

Thank you for your time.

It does not sound like you are doing anything wrong, but I do suggest you use bit-torrent (KTorrent if you had KDE already loaded). But, why not just download the KDE Live CD at 686 MB? I would do that in a heartbeat if I had the same situation you are having. You can then use if for an install and try to get the other things you want later.

Thank You,

The best method is a good metalink downloader, like aria2c. It uses the
full bandwidth you have, and all methods it can: direct http, torrent,
whatever. And it verifies and corrects errors in the downloaded image.

I like to stick just with torrent (any client should be fine You could even use the opera’s bulit in client but I personally don’t like it). As far as I know it guarantees proper download and is very fast for me.

Best regards,

Torrents do not guarantee a clean download, one should always check the md5. However, I think it’s the most friendly way, since you share the download with others and unburden the http/ftp-servers of openSUSE. Torrents are usually quite fast as well, since they are shared by hundreds or even thousands of seeders.

If you do not want to use a torrent, check →this mirror-list for a server close to your destination. You could simply download the .isos with wget, it uses the full bandwidth as well. The md5 of the i586 / 32bit-version is

1a1da28c84e3cdad750d5cfa21c4fd17

And in addition to the above, don’t make the mistake of trying to download modern openSUSE isos to Fat32 drives or partitions. Modern isos are bigger than the file size limit for Fat32 (4GB) so an attempted download will simply abort when you exceed this limit (been there, done that, got the t-shirt).

aria2c uses also torrent. It uses everything.

Yes, they do, if the client is good enough. It actually can repair a bad
iso file downloaded via http that has a bad checksum.

The torrent protocol has partial file checksums, that serve to know if a
part of a file is bad, and re-download that part only. It is a p2p
protocol, and it has to handle that some of the peers, accidentally or
intentionally, provide bad data. It can, I think, black list those peers, too.

Another application is to use the download accelerator ‘prozgui’ (thats what I use). I do not find it to accelerate the download more than a nominal download, but I do find the checksums that the download accelerator does ensures the downloaded file has no errors. Hence it is SIGNFICANTLY more reliable than a nominal download, and its also a lot faster than bittorent, …

BUT it is more selfish than bittorent and does not share the file when downloading.

Hence in addition to using prozgui, I also recommend users share with a bittorent application

@robin_listas: I only use KTorrent and can not speak for other clients - it indeed has a feature to check downloaded files or the blocks downloaded so far, but this has to be set manually. Either way, it’s still a good idea to compare the checksums, whatever way is used. Doesn’t take too much time anyway.

Ah, I was wondering why my Internet was boring of late. Thanks. :wink:

Thus, aria2c, I insist :slight_smile:

It downloads “normally” from any source it can find, from several sources
actually, and simultaneously, till it fills all your bandwidth. It checks
by chunks (if the person that uploaded it thought of doing that), and
downloads again the bad chunks only. And will also share via torrent what
it has already downloaded.

It has everything! :slight_smile:

I note it being here: aria2 project

… but I don’t see any packaged rpms for openSUSE.

Likely building from tarball won’t be difficult, but not everyone knows how to do that.

Hmm? It’s in the standard repo:

$ which aria2c
/usr/bin/aria2c
$ rpm -qf /usr/bin/aria2c
aria2-1.9.3-0.1.1.x86_64

Psst, search for aria2, not aria2c.

Ahhh … I’m bad! :slight_smile:

It is the current default downloader used by zypper and yast, so you have
it or your system is hosed >:-P

And it is a required part of the repo redirector. We depend on in.

Do you happen to be using a 2Wire DSL modem supplied by Qwest? If so, that particular modem has a firmware bug that prevents you from downloading files larger than 2GB. If you do, let me know and I’ll tell you what you need to do about it.

Thank you for all the help. Since I am re-visiting suse, I have forgotten quite a bit about the downloading and checksums.

  1. I do not have linux loaded to install the download managers mentioned above. I only have Windows 7 to work with or Windows XP if they won’t load on Win 7. I found that to be the case on one I found with a google search.
  2. It is stated that even though the download manager has a check-sum, you should check it again. I presume this is after you download the iso from the website. If it does not match I guess you are in for another download of x amount of hours. I see why it is easier to just purchase the new version!

Thank you for your help

One of the advantages of downloading a torrent is that in case the checksum is wrong, you’ll only need to re-download the blocks that were corrupted.

On Windows I use FreeDownloadManager. It works really well either in standalone mode or as a plugin within the Firefox browser. It easily handles downloads over HTTP, FTP and BitTorrent. I just click on the link to the torrent file in the openSUSE repository. It downloads a small file to my Downloads folder. I run that file and it handles the downloading. I’m doing it right now to get openSUSE 11.4 Milestone 3.
