I turned off the firewall. Then, using nmap in the terminal, I issued the statement
nmap 127.0.0.1
and got
Starting Nmap 7.12 ( https://nmap.org ) at 2016-08-15 11:00 PHT
Nmap scan report for localhost (127.0.0.1)
Host is up (0.00016s latency).

How can I force open TCP 443 on my machine?
Best Answer
To force open any port you can use
nc
(netcat).The command
sudo nc -l 443
will open port 443. Of course this will not serve any web pages. But it will be listed in your namp output as open port.By specifying an interface with
-b <if>
you can bind it exclusively to it - other interfaces (e.g. en1) shouldn't show an open port 443 then:Check for more options by executing
man nc
.
