I am running Macos X 10.4.8 on an macbook pro.
When I attempt to start the server I get the error
Vine Server can’t listen on the specified port (443).
Probably because another VNC is already using this port.
I can start the server fine on some +1000 port, such as 1234.
I have tried ps -aux and used grep to look for apache, tomcat, httpd, anything else that looks suspicious. I can’t find anything that would be taking port 80 or port 443.
Is there another way of finding out what is using a port? Is there any other reason Macos X would not let an application use a port?
