Red Hat NETWORK SATELLITE 5.3.0 - RELEASE NOTES Release Note page 6

Chapter 1. Major Features
• The RHN Satellite Application Programming Interface (API) has been expanded and now features
several new calls, including new calls for the multiple organizations feature, Cobbler installation
server, and system and errata search.
• RHN Proxy Server now supports command-line installation via the configure-proxy.sh
program, which allows administrators to install RHN Proxy Server through a series of interactive
prompts. For more information on using the command-line installation program, refer to the Red Hat
Network Proxy Installation Guide.
• RHN Satellite now supports multiple architectures within a single registered system that is running
Red Hat Enterprise Linux 4.8.0 or later and Red Hat Enterprise Linux 5.3.0 or later. RHN Satellite
now displays the architecture of installed or available packages when queried along with package
names; and users have a choice to install, update, or remove packages according to architecture.
• RHN Satellite and RHN Proxy Server now feature support for SELinux targeted policy in
enforcing or permissive on Red Hat Enterprise Linux 5.3.0 or later. SELinux is a set of secure
software policies that implement mandatory access control to Red Hat Enterprise Linux and other
operating systems. SELinux is activated by default on Red Hat Enterprise Linux, and now users can
have SELinux in enforcing or permissive mode with the targeted policy during installation of
Proxy or Satellite.
Note
Installation on an SELinux system is only supported in Red Hat Enterprise Linux
5.3.0 or later, and is not supported on Red Hat Enterprise Linux 4.
• SELinux modules that support Monitoring of RHN Satellite and RHN Proxy Server on Red Hat
Enterprise Linux 5 are now available. Note that because this feature is a Technology Preview, it may
not be functionally complete and is currently not supported for production use.
For more information, refer to
• RHN Satellite now supports Solaris for UltraSPARC T1 (sun4v) and X86_64 processors.
