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
Ncat: Connection from 127.0.0.1.
Ncat: Connection from 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.
