Hi Marek >Full info comes right your way :)): Cheers a lot! But how come I don't have that? :*! There's sort of an empty man page describing that other infos can be found locally under /usr/doc/nmap/... *My* nmap doesn't recognise the "-O" flag. I am unsure about its version, but I'm running slink, so maybe that's why? What are you running? Or do I maybe need to install another package? Sven
