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 <code>system.listMethods</code>
|
||
|
|
XML-RPC call, which however does not distinguish the two versions. Version 3.0.1
|
||
|
|
returns a response to <code>system.listMethods</code> 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
|
||
|
|
<code>system.listMethods</code> method call. If an error is
|
||
|
|
returned, return "3.0" or "3.0.1", depending on the specific format of the
|
||
|
|
error.
