[NSE] Update to bacnet-info

Hello All, Based off a merge request, we have updated the bacnet-info (or as we still call it on github BACNet-discover-enumerate). Please consider this as an update, and incorporate into the existing version if you see it fit. in summary, two new queries to pull the information about the BBMD as well as the FDT. BACnet Broadcast Management Device (BBMD) is functionality within a BACnet router to allow it to manage connectivity to other BACnet hosts on disparate subnets via UDP Unicast messaging (many-to-many communication). Entries in a BBMD table will receive unicast copies of all local broadcasts seen on a BACnet/IP network. To facilitate this, all routers serving a specific group of hosts will be pre-programmed with a common BBMD table. Two (or more) hosts that have each other in their BBMD table have a clear relationship since they are managed as one BACnet broadcast network so all devices behind each BBMD can communicate via traditional BACnet WHO-IS/I-AM. Foreign Device Registration (FDR) is functionality within a BACnet router to allow it to perform UDP Unicast messaging with one specific other device on a disparate subnet (one-to one communication). To facilitate this, the Foreign Device submits its IP and other details to the BACnet router, and all messaging that would be managed as a local broadcast by the router is then shared with the Foreign Device, and the Foreign Device uses the router as a destination for all messages it would normally broadcast. Entries in the Foreign Device Table (FDT) on the router have a clear relationship with the BACnet broadcast network that the router is attached to. The Script will now pull the BBMD and FDT from the devices via a simple query. This does not change the state of the BACnet device. Also implemented a script arg so that the original script can still be ran as it was before this merge request. https://github.com/digitalbond/Redpoint/blob/master/BACnet-discover-enumerate.nse _______________________________________________ Sent through the dev mailing list http://nmap.org/mailman/listinfo/dev Archived at http://seclists.org/nmap-dev/
