The virtual appliance MUST be able to resolve its own host name. Please verify that by opening a terminal window (click "Terminal" on the desktop) and using the ping command. It is recommended that both host/common name as well full qualified domain name are pingable. See System Requirements for incoming and outgoing network access requirements. |
When changing the host name (default is "iDNA Applications") in the Host Information application, please make sure to adapt the host alias properties for 127.0.1.1 in /etc/hosts. This can be done using the gedit application. It is recommended that both host name and full qualified domain name are entered here:
Host Name Configuration:
The host name of the appliance must be changed to reflect the DNS settings in the customer's environment. This can either be accomplished by using the desktop application "Host Information" or by manually editing the file /etc/hostname.

Important: The host name must not be simply "idna", as that may lead to connectivity issues. |
Editing via "Host Information"
In this field, only the server's common name is entered. E.g. if the full server name is "server1.acme.com", only "server1" would be entered here.
Editing "/etc/hostname" manually
When editing the hosts file (e.g. with gedit or vim), both the common name and the fully qualified name should be entered as additional alias for 127.0.0.1. The existing aliases "localhost" and "localhost.localdomain" must remain as aliases.

Please note that the iDNA Applications notification feature uses the this host name to indicate the affected appliancein emails to identify from which server the email has been sent. For further details refer to Setup Notifications (Mailprofile). |

It is very important to adjust the appliance's time zone! Please reboot the appliance after changing the host name or date/time settings as the web server and database system require a clean start with the new configuration. |
