For some reason I can't open port 80, so my install is using 8080.
how can I find the exact service using port 80 and terminate it or uninstall it?
To find out what processes are using which ports, you can use the '-p' option to netstat (this must be done as root). the command I always use is:
This shows all open, listening, udp, tcp sockets, and what process has them open.
