X and Character Applications

15-bit color depths are not supported. If this color depth is specified on the Remote Desktop Session Host,

SGD automatically adjusts the color depth to 8-bit.

2.4.3.4. Encryption Level

You can only use the Low, Client-compatible, or High encryption levels with SGD. SGD does not support

the Federal Information Processing Standards (FIPS) encryption level.

2.4.3.5. Transport Layer Security

From Microsoft Windows Server 2003, you can use Transport Layer Security (TLS) for server

authentication, and to encrypt Remote Desktop Session Host communications.

2.4.3.6. Network Level Authentication

If the Remote Desktop Session Host supports Network Level Authentication (NLA) using CredSSP, you

can use NLA for server authentication.

2.4.4. X and Character Applications

To run X and character applications, SGD must be able to connect to the application server that hosts the

application. SGD supports SSH and Telnet as connection methods. SSH is the best for security.

SGD works with SSH version 2 or later. Because of SSH version compatibility problems, use the same

major version of SSH, either version 2 or version 3, on all SGD hosts and application servers.

If you are using SSH to connect to X applications, you must enable X11 forwarding. You can do this either

in your SSH configuration or by configuring the application in SGD. The Oracle Secure Global Desktop

Administration Guide for Release 4.7 has details on using SSH with SGD.

SGD supports the X Security extension. The X Security extension only works with versions of SSH that

support the -Y option. For OpenSSH, this is version 3.8 or later

2.4.4.1. X11 Software

SGD includes an X protocol engine (XPE) implementation based on the X.Org Foundation X Server

release X11R7.6.

The XPE implementation is based on the following X.org foundation sources:

• xorg-server 1.9.3

• xrandr 1.3

• xkeyboard-config 2.1

The following versions of X.org dependencies are used:

• Mesa 7.9.2

• pixman 0.20.2

2.4.4.2. Supported X Extensions

SGD supports the following X extensions for X applications:

• BIG-REQUESTS

1 2 ... 23 24 25 26 27 28 29 30 31 32 33 ... 51 52
