Host and domain name by security label

Installations that start several TCP/IP stacks under UNIX System Services CINET often find it necessary to define a different host name or domain name for interactive users based on their security label. The first decision that needs to be made is what host name and domain name each TCP/IP stack will have. Two common approaches are to:

• Assign each of the stacks a different host name in the same domain name.
• Assign each of the stacks on the same z/OS® image the same host name, but define a different domain name for each security label.

These names are then implemented by creating a separate resolver configuration file for each security label.
