Most port scanners (nmap being the most prominent example) correctly
report ports as either open, closed or filtered. There's no such thing
as "stealth".

Sadly most port scanners, including some based on Nmap, have bad frontends
that are either broken (thus reporting stuff that has never been measures by
the backend, or belongs to a different session) or spill the reports
(including a mapping of words (open,closed)->"open, insecure, bad", closed
-> "stealth, secure, good" as well as bad filtering and transformation).

So better use Nmap directly or some known good frontend (like
<http://linux-sec.net/Audit/nmap.test.gwif.html>).
