The utadm command is not able to parse the default /etc/hosts file when trying to configure the Sun Ray network. The following error may occur when using the utadm -a or utadm -A commands on an Oracle Linux-based Sun Ray server:

Error: host IP address must be set.
Set host IP address and try again

On Oracle Linux systems, you must make sure that the system's host name specified during the Oracle Linux installation is configured properly in the /etc/hosts file. The system's host name must be on a separate line in the /etc/hosts file with an IP address matching the host's primary IP address.

Here is an example of an etc/hosts file that contains the system's host name, srshost, on the same line as localhost:

127.0.0.1       srshost localhost.localdomain localhost
::1             localhost6.localdomain6 localhost6

The srshost host name must be on its own line for the utadm command to work:

127.0.0.1       localhost.localdomain localhost
::1             localhost6.localdomain6 localhost6
192.168.1.1     srshost
