Hi Ken,
As far as I am aware, if a port is showing up as 'closed' instead of
'filtered', which i assume you mean when you say 'stealth', it means that it is
sending a tcp reset packet to the tcp packet it received as apposed to just
dropping the packet. I am not a networking guru but I would not class that as a
bad thing as it is sticking to the RFC.
Most firewalls by default drop packets that are not explicilty allowed, unless
told to send a tcp reset, but most OS's will send a tcp reset if the port is
closed.
I hope this helps.
Regards,
Charlie

Securing Apache Web Server with thawte Digital Certificate
In this guide we examine the importance of Apache-SSL and who needs an SSL certificate. We look at how SSL works, how it benefits your company and how your customers can tell if a site is secure. You will find out how to test, purchase, install and use a thawte Digital Certificate on your Apache web server. Throughout, best practices for set-up are highlighted to help you ensure efficient ongoing management of your encryption keys and digital certificates.
