Script Summary

Detects the version of an Oracle Virtual Server Agent by fingerprinting responses to an HTTP GET request and an XML-RPC method call.

Version 2.2 of Virtual Server Agent returns a distinctive string in response to an HTTP GET request. However versions 3.0 and 3.0.1 return a generic response that looks like any other BaseHTTP/SimpleXMLRPCServer. Versions 2.2 and 3.0 return a distinctive error message in response to a system.listMethods XML-RPC call, which however does not distinguish the two versions. Version 3.0.1 returns a response to system.listMethods that is different from that of both version 2.2 and 3.0. Therefore we use this strategy: (1.) Send a GET request. If the version 2.2 string is returned, return "2.2". (2.) Send a system.listMethods method call. If an error is returned, return "3.0" or "3.0.1", depending on the specific format of the error.
