In previous versions users had to access directly the ESXi server in order to re-configure configuration files to enable services that VMware did not want to support. However in ESXi5 these services can be enabled/disabled by using the vSphere Client. It is very simple.
In vSphere go to:
– Configuration Tab
– Select “Security Profile”
– You will see all available services ESXi5 comes with and their status.
– Select properties and you will be able to enable/disable services and you will also be able to configure basic firewall rules for that specific service.
