First it tries to determine the names of all objects bound in the registry, and then it tries to determine information about the objects, such as the the class names of the superclasses and interfaces. This may, depending on what the registry is used for, give valuable information about the service. E.g, if the app uses JMX (Java Management eXtensions), you should see an object called "jmxconnector" on it. It also gives information about where the objects are located, (marked with @:port in the output). Some apps give away the classpath, which this scripts catches in so-called "Custom data". ]] --- -- @usage nmap --script "rmi-dumpregistry.nse" -p 1098 -- @output -- PORT STATE SERVICE REASON --
