There are some suggestions in "Hacking Linux Exposed". One is put a dedicated firewall or linksys router between your machine & the net, then nmap sees the firewall but not your actual system. IPLog includes functionality intended to fool nmap and xprobe & can be found at < http://ojnk.sourceforge.net >. IPPersonality will "enable your machine to impersonate any " OS, found at < http://ippersonality.sourceforge.net >. The authors offer a caution that such measures may impact your performance or compatibility. These solutions will work for Linux but probably not windows.
