There really is no way to make your server "invisible" persay. You can
use firewalling to block certain ports, etc. but say if you cut off ping
reply's, there is a chance you might affect other service's ran on the
server. As far as OS detection..there are some steps you can take so that
(never implemented this) so that say you run FreeBSD
4.4-RELEASE, but if you do an OS detection on the machine it reports back
Windows2000, etc. If you are not really concerned with that, but just
don't want people scanning you, install a IDS system that will notify you,
log, add firewalling, etc. of any scan attempts.
