    CanYouSeeMe.org - Open Port Check Tool

    This is free web based utility for remotely verifying a port is open or closed.
    It will be useful for users who wish to check to see if a server/computer is running
    or a firewall or ISP is blocking certain ports.

    I think the gold standard for this stuff is:


    About halfway down is "ShieldsUp!" A great tool for this sort of stuff (and much more user friendly.) This site also has a wealth of information on securing your system should you find any vulnerabilities...

    I would strongly recommend people NOT to use grc.com - the information it gives you is often false. Canyouseeme.org is a no frills test site - it tells you *exactly* what you need to know, but without any scaremongering.
