	Note
	Keep the operating system fully patched according to recommendations by the operating system vendor.

The supported operating systems are required to have the following or superseding patches or maintenance levels installed. Tectia solutions have been tested with the following patches and maintenance levels:

IBM AIX 6.1: Technology level 3 (fix to AIX bug IDs IZ46727 and IZ17492). Note that these fixes are also available as service packs for some earlier technology levels.
IBM AIX requires the following updated C++ runtime libraries:
- Fileset update: bos.rte.libc 5.3.8.1
- Fileset update: bos.rte.security 5.3.8.1
- Base level update: xlC.rte 10.1.0.0
Microsoft Windows Server 2008: Service Pack 1.
Red Hat Enterprise Linux 4 and 5: xorg-x11-xauth is required for X11 forwarding
SUSE Linux Enterprise Server 10: Service pack 1

HP-UX patches

The general principle is to install the latest HP-required patch bundle for the OS version, currently required bundles exist for 11i v1 and 11i v2. Proper functioning of the Tectia software also requires the latest HP recommended patches for libc, pthread and linker tools. In addition, some individual patches may be needed to fix specific problems. Such patches are mentioned separately.

	Note
	Check the HP web-site for any newer patches superseding the ones listed here. We recommend installing the latest version recommended by HP.
