    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.

    lol

    really interesting topic

    linux can protect you from windows malware (worm, virus, trojan, windows applications exploit, windows rootkits)

    but there is a lot of linux rootkits around
    a rootkit scan an ip adress or a range ip looking for some defined open ports (associated with known process security whole)
    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.

    lol

    @xaoz
    thanks for the help

    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

    regards
