You do realize ".torrent" files are only meta-information used to help you download what you want from the BitTorrent filesharing-network, right?
If not, it's a last resort. First, it is not totally safe, no matter how they say they try to scrub the files...probably not a huge concern if you are running anti-virus software (though AV software froze FOR A LONG TIME in the middle of the download, while attempting to block the download, before the files even finished downloading). Second, it takes FOREVER for something like this...possibly days. The less people are sharing the files you are seeking, the longer it takes. Most people share music, and how much do you bet that people aren't willing to dedicate their computer upload link to files of that size, anyway? It would have took me 2 days even if it had not froze, going by the way the speeds were changing, even though I followed instructions found on the Internet to optimize.
I think http or ftp downloads are better, whether you will be downloading the CDs or the single DVD. Finding the DVD link is a pain in the but, but it's worth it if you have a DVD burner.
OK, it's a pain in the butt to find (though this makes the third time for me). Here is the page, with the MD5s or ASCs you need to check the integrity, links to ALL install files (CD and DVD), and info:
And here is the direct link to the ISO file for the DVD (if you can do a DVD):
And here is the MD5 sum direct link (it's just text):
If you don't have or know how to use "md5sums" for Windows, look it up on the Internet. I am not at my home computer right now. But you need to save it to somewhere easy to type on the Windows command-line, without spaces, to make it easy to use. Like directly under your "C:\" directory is a good place.
(I am inferring you are on Windows right now, trying to install Linux. Am I wrong?)
Download the ISO, run "md5sums" on it (you have to use a particular option, or "flag", to make sure your command-line window doesn't close the second it finishes running), and compare the result to the string of characters in the text file. If they match, the file has not been tampered with nor damaged during download.
If you are doing CDs, you obviously want to check the integrity of each one before you burn it.
Then, hike it on over to the http://www.slackbook.org
website for the docs.
I'm assuming you know how to burn an ISO on Windows and have some software. If not, I recommend CDBurnerXP Pro, which is free. Actually, it seems they took off the "Pro" part (probably makes people think of a paid version). Here is the website: http://cdburnerxp.se/
There are lots of free programs that will claim to let you burn ISOs, the trouble is they are really "trial" versions, because they put a limit on the filesize, so you can't burn anything remotely useful with them (like an operating system). However, CDBurnerXP does not have a limit. And it has a helpful user community, even though it is not open-source. Isn't that nice?
