Now I get it, it is explained here .

Assuming the Firewall is turned off, then in order to ping $HOSTNAME, there has to be some form of sharing or service enabled in System Preferences > Sharing, or add an entry to the /etc/hosts file, depending on how/what you're trying to access by $HOSTNAME. Example, 127.0.0.1 computer_name where computer_name is what's reported by echo $HOSTNAME or in lieu of 127.0.0.1 the actual IP Address of the Network Adapter on your system.
