RE: namp might report wrong port state

[Steve Zhou <zhoucengchao () hotmail com>]

Hi nmap team,

 

Sorry for bothering, I have a question when I using nmap. I have an
application listening on TCP pot 13456 runs on a server as you can see
below. The name is ktconsService.exe.

 



 

When I nmap to scan the port, it says the port state is "closed", but I can
connect to the application without any issue.

 



 

May I know why nmap reports the port state as "closed" even when the port
can be connected?

 

Thank you
