When I try to start XAMPP with sudo /opt/lampp/lampp start command it gives me a message like this.
Starting XAMPP for Linux 1.7.7...
XAMPP: Another web server daemon with SSL is already running.
XAMPP: Starting MySQL...
XAMPP: Couldn't start MySQL!
XAMPP: XAMPP-ProFTPD is already running.
XAMPP for Linux started.
What is this and how can I find what was this another web server daemon with SSL.
