couple of points:
        1-It does not work for me;
                
                FreeBSD lorax.neutraldomain.org 4.3-RELEASE FreeBSD
                4.3-RELEASE #0: Sat Jun 23 01:52:58 PDT 2001
                root@lorax.neutraldomain.org:/usr/src/sys/compile/lorax
                i386

        2-At first I tried it with /tmp mounted no-exec (thats what i
        have in fstab) I thought that was why the exploit didnt work,
        remounted /tmp without the no-exec flag and tried again. It
        still does not work, it hangs for hours on end, this last
        iteration has been running for a couple days now and nothing has
        come of it.

Ideas on why it doesnt work? --gabe
