Hello nmappers, Attached is a small patch for showSMTPversion.nse which prevents its action() from returning two values: return string.gsub(result, "\n", "") Both a string and the number of replacements made are returned and this results in some weirdness which I've not been able to fix: Initiating SCRIPT ENGINE at 23:51 SCRIPT ENGINE: The script has no 'id' entry, the 'filename' entry was changed to: nil SCRIPT ENGINE: Script scanning completed. SCRIPT ENGINE: Aborting script scan. The script has an id and there's nothing wrong with the filename (matches the entry in scripts.db). It seems that when action() returns two results it somehow messes with the Lua stack (or something like that) and process_getScriptId() in nse_main.cc results in script abortion. Whilst fiddling, I found that (on windows at least) the script filepath (rather than just the filename) is output in the script results if the script does not have either an id or filename field. I'm not sure if that is the intention - I thought I'd mention it anyway.
Thank you Jah for locating this. Currently there is a unofficial rule that a script may only return one value. This will be changed when time permits.
