Is the difference between Linux and FreeBSD normal, or a cause for concern? If it is a concern, how would I strengthen the FreeBSD sequence randomness? Thanks very much, Seth Hieronymus _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
