It generates a file out of random bits returned from /dev/urandom, I think /dev/random is also possible. See here [1] and [2] for more information. I thinks it was just meant as a sample file to compare the md5 checksums. [1] http://en.wikipedia.org/wiki/Urandom [2] http://www.linuxmanpages.com/man1/dd.1.php -- [EMAIL PROTECTED] mailing list
