I for one would not trust "Shields Up". Firstly I believe it is targeted
at MS OS's and secondly I wouldn't even trust it for that as it only
scans a few (well known) ports (IIRC). I don't think much of S. Gibson
either but that is another story. Why use a badly designed tool which
gives false results when the people who are trying to get into your
computer use only the best?
You would be better off using a number of scans from a variety of
sources, perhaps using nmap as others have suggested. One site I use is:
http://www.linux-sec.net/Audit/nmap.test.gwif.html it allows you to use
nmap with *user* *defined* *options* (see nmap manpage on google). There
are many online scans if you google: "nmap online" or some such similar
thing.
