A minor updates about the iso: A few people have complained about that the iso being corrupted. Leon has kindly uploaded it to me again, this time with a md5checksum. And I guess this iso was very appreciated, it has been downloaded over 1000 times already =) The md5check is placed at http://xent.d2g.com/temp/other/m5sum.txt and the iso at http://xent.d2g.com/temp/other/sans_security.iso as before. As this is the same iso you should be able to resume your download.
