2 System Overview
The Target of Evaluation (TOE) is SUSE Linux Enterprise Server (SLES) running on an IBM eServer host
computer. The SLES product is available on a wide range of hardware platforms. This evaluation covers the
SLES product on the IBM eServer System x™, System p™, and System z™, and eServer 326 (Opteron).
(Throughout this document, SLES refers only to the specific evaluation platforms).
Multiple TOE systems can be connected via a physically-protected Local Area Network (LAN). The IBM
eServer line consists of Intel processor-based System x systems, POWER5™ and POWER5+™ processor-
based System p systems, IBM mainframe System z systems, and AMD Opteron processor-based systems that
are intended for use as networked workstations and servers.
Figure 2-1 shows a series of interconnected TOE systems. Each TOE system is running the SLES operating
system on an eServer computer. Each computer provides the same set of local services, such as file, memory,
and process management. Each computer also provides network services, such as remote secure shells and
file transfers, to users on other computers. A user logs in to a host computer and requests services from the
local host and also from other computers within the LAN.

User programs issue network requests by sending Transmission Control Protocol (TCP) or User Datagram
Protocol (UDP) messages to another computer. Some network protocols, such as Secure Shell (ssh), can start
a shell process for the user on another computer, while others are handled by trusted server daemon processes.
