For Dionaea to parse the Nmap NSE well, a simple patch need to apply to Nmap. This is due to the reason that Nmap has fixed the "Alloc hint" value in the DCE_RPC request packet. Dionaea need this value to parse the following StubData.
For the moment, there is no any official changes from Nmap. We need make this simple change manually in /nselib/msrpc.lua
Here the diff
Thank Markus to the patch
