A simple portscan will also catch Unixoid systems running PortSentry if
they have 143[34] in the config file.  These ports are *not* in the stock
config file for PortSentry 1.1.1.

However, you are correct in thinking that if the port isn't open, then the
box in question is not vulnerable.  Did you actually find boxes that had
SQL or MSDE running but no port open?
