X-Ray


General Information

X-Ray is a Session Management Environment for Unix, which is comparable to Windows TermialServer. It allows the user to disconnect his actual session and continue from any other computer at the very same state he left the session before. X-Ray offers you a native session management for X applications like VNC or SunRay with remote (dis)connects to a server-side running session. But instead of sending pixmap deltas, Xray sends the native X commands over the wire. This allows usage of eg. the X compression proxy ML-View , it should work perfectly with any application firewall really sniffing the X commands, and is also capable of using hardware accelerations on the client-sides' graphics card.

The additional tools include xray[dis]connect commands, which allow multiple users connecting from different clients, but using the same server by attaching Xray instances to their UID. It also comes with the necessary server-tools and the control daemon (X-Ray Hub).
There is also a tool xrayps, which gives you information about online and/or connected sessions.
