There was a problem hiding this comment.
The option to comm.tryssl should be recv_before and for this protocol it should be true. I've updated the docs for that function since I've had trouble understanding it in the past as well. recv_before means "if it's plaintext, you'll get a banner" essentially.

Thanks for the review. We'll get the updated version tested and back to you in about 3 weeks, since @JaySmithWpg and the test environment are inaccessible until then. |

https://secwiki.org/w/Nmap/Script_Ideas#.60openflow-info.60_and_service_probe
Script for gathering information from openflow controllers and a service probe for all versions.
Unfortunately, all of the really interesting information gathering packets in openflow, such as feature request or description request, are designed to be sent from the openflow controller to the switch (played here by nmap) rather than the other way around. For newer versions of openflow (>= 1.3), we are able to at least enumerate all supported versions of the protocol spoken by the controller.
