    1. Turn off services that are not needed/used
    2. Setup a firewall to block all port except the ones needed to be open


    For example if this server is a web server then you only need ports 80 and 443 (if you are using secure) open and maybe port 22 for management. Everything else should be blocked with a firewall and all other services should be turned off.

    honestly, the best way to do this would be to put another machine inb/t your pc and the rest of the world that is running iptables/firewall.

    there is a discussion here about doing what you want, and some possible options, but don't hold your breath.

    Edit: my suggestion pertains to preventing OS detection specifically. what lazydog suggests is definitely the first thing you should do.
