Virtual Network Computing (VNC)
VNC is a customized version of a GNU
The version of VNC shipped with the SunPCi III 3.2.1 release contains two components:
■Xvnc - A modified X11 server that renders data into a virtual frame buffer
■vncviewer - An X11 client that enables the contents of the Xvnc virtual frame buffer to be displayed on another X11 display
The installation and setup of Microsoft Windows or Linux via VNC is not recommended for the following reasons:
■Multiple cursors appear in the window, making mouse use confusing.
■The amount of window data generated during installation is high because of constant updates by the VGA emulation, which slows the installation process.
For optimal performance, complete the installation process while displaying information on a local monitor. If this option is not possible, complete the installation while displaying to a remote monitor is a better option than using VNC. Installation using VNC is strongly discouraged and should only be used as the last option. This issue is present for the installation of all operating systems that can use VNC.
The Xvnc server allows SunPCi sessions to display to what appears to the software as a normal X11 display. Xvnc is ordinarily started by the SunPCi daemon before starting the SunPCi sessions.
The vncviewer enables system administrators to interact with the SunPCi cards, either locally on the server where the cards are installed (assuming that the server has a display attached), or remotely on any Sun machine (including a Sun Ray™ display) that is running a Sun X server. With the combination of the vncviewer and SunPCi displaying to the Xvnc server, it is possible to attach “on the fly” to a currently running VNC session from any Sun machine on the network, and to interact with SunPCi sessions running on a remote server. The VNC session can be detached and later reattached from a totally different machine. The SunPCi sessions continue running even though no one is interacting with them.
