I noticed that ngolf at zonnet.nl was thankful that he was able to "download" instead of "torrent", however I am not. (http://lists.ourproject.org/pipermail/musix-users/2006-December/000432.html ) <[email protected]> <[email protected]>"Downloading" (http/ftp) relies on the underlying TCP layer for error control, which uses a weak checksum by modern standards. In addition to distributing transmission bandwidth, modern peer-to-peer protocols provide an additional layer of error control. Long story short - I have a corrupt ISO file, which would Not have happened with Bit Torrent, (or Gnutella, or eDonkey) Maybe one of you could send me the output from this command: for a in `seq 0 697`; do (dd if=MusixGNU+Linux- 0.79b19.iso bs=1M count=1 skip=$a 2>/dev/null | md5sum >> MusixGNU+Linux-0.79b19.md5sum.1M); done And I can manually recover the file; maybe downloading only 1 meg to repair the file. Otherwise, I'll have to begin downloading the entire 697 Megs all over again.
