[quote="Bukowski"]so true, de"fault knoppix is definately not something you want to go on the internet with, not only you have to lock down services, try to upgrade the kernel(it's bugged) and remove a bunch of useless (suid) files too, when you don' with that, it starts to get reasonably to work with it, although you're not finished yet: you may want to secure/upgrade specific services too.Quote:

it logs the scan result in a file and ask you if you want to try to exploit the security wholes on the target comp
there are some root kits you can add your own exploit
so put a linux workstation directly on the internet is not so secure as it seems
my mandrake 8.1 webserver installed behind a secured debianbox was hacked two times in a year
actually, what you describe is a worm, a rootkit is a set of utilities, typically kernel level enhancements that try to hide anomalous activity. for instance, hide network connections as seen wirh netstat, processes as seen by ps, it sometimes adds a icmp backdoor etc.Quote:

as you can find over 70 000 windows malwares
as you can find up to 70 linux malwares, linux is a natural protection
the actuals most knows rootkit are like you have defined
but this is just a kind of rootkit
a rootkit is a tool which will give a root access on a target comp
as there many ways to try to do it, every tools attempting to do it are called rootkit
when i see debian router box's firewall log, i can see the attacks
it's very interesting too
