Introduction
A terminal server is a Linux™ instance that provides access to terminal devices on other Linux instances, called target systems in this document.
The terminal server and all target systems run as guests of the same z/VM® instance. Terminal server and target systems are connected through the z/VM Inter-User Communication Vehicle (IUCV). From the terminal server, administrators can access terminal devices on target systems without requiring direct TCP/IP connections to the target systems.
You can use a terminal server to achieve these
goals:
- Increase availability by providing emergency access to target systems if the primary network for these systems fails.
- Heighten security by separating user networks from administrator networks or by isolating sensitive Linux instances from IP networks.
- Simplify systems administration by providing a central access point to target systems.
