Robin,

Understood.



However, ‘ncat -nlv <port#>’ does not work with the same message.



Both variations worked in other versions, but in 7.25BETA2 is appears that the -l parameter is being ignored.

If you are trying to set up a listener then you don't need the -p, that is to specify the source port:



$ ncat -lnv 8080

Ncat: Version 7.01SVN ( https://nmap.org/ncat )

Ncat: Listening on :::8080

Ncat: Listening on 0.0.0.0:8080<http://0.0.0.0:8080>

Ncat: Connection from 127.0.0.1.

Ncat: Connection from 127.0.0.1:56634<http://127.0.0.1:56634>.

   happens regardless of port number specified.



   specifying a local IP results in:

   “Ncat:  Connection refused.”



   nc works fine, so definitely something connected to Ncat, almost like the listener module is being completely 
bypassed or ignored.
