How to install phalcon?

Answer 1

install git first
but that's not the best idea. it is better to clone it locally and copy it to a server

Answer 2

1) True. Only a listening port can be identified as open.
2)
3) "Does this mean that the browser is acting as a server and accepting connections from port 443", no, it doesn't. These are the ports and addresses of the web server that Firefox connects to.
4) There are no guests on the ports. Every manufacturer is up to something. In 99% of cases, UPNP is simply enabled.
