Could anyone tell me how I can manipulate these two options in FreeBSD? thanks in advance, Nazila ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
