Xvnc is an X server based on the open source releases from the RealVNC project and X.Org Foundation. The Solaris operating system also includes the RealVNC vncviewer program. Virtual network computing (VNC) is a remote control software that allows you to view and fully interact with one computer desktop, the Xvnc server, by using the VNC viewer on another computer desktop. The two computers do not have to be running the same type of operating system. VNC provides a guest domain graphical login.By default, consoles for HVM guests are graphics consoles. You can use VNC to view a Windows guest domain from a Solaris control domain.Xvnc displays to a VNC viewer over the network. A VNC viewer is a remote framebuffer (RFB) graphical user interface. Xvnc is a simple protocol for allowing remote access to an RFB protocol client over the network, without requiring an existing X server session to be displayed on local hardware. Xvnc also includes the RealVNC vncviewerclient to connect to remote VNC servers, and several associated management programs.Xvnc is the X VNC (Virtual Network Computing) server. Based on a standard X server, Xvnc has a virtual screen rather than a physical one. X applications display through a VNC viewer as if to a physical X display.The VNC server display number is the same as the X server display number. For example, snoopy:2 refers to display 2on machine snoopy for both VNC and an X server.To see the list of Xvnc options, use the help option:Xvnc helpMany options are standard X server options. In addition to options that can only be set at the command line, there are also parameters set through both the command line and the vncconfigprogram.To start Xvnc, use the vncserver script.The server can be started by the x11-server SMF service.For more information, see the Xvnc(1), Xserver(1), vncconfig(1) vncviewer(1), vncserver(1) man pages. Use the vncpasswd command to set the password used to access VNC desktops. The password is stored on the server. For more information, see vncpasswd(1) and Example 40–6. This procedure shows how to start VNC on demand from inetd, displaying the dtlogin login screen.When using this method, you must restart the service, which will kill all current dtlogin sessions. Become superuser, or assume the Primary Administrator role. Enable XDMCP connections on dtlogin by removing -udpport 0 from the arguments.# svccfg -s cde-login svc:/application/graphical-login/cde-login> setprop dtlogin/args="" (Optional) If you are not running vncviewer locally on the control domain, set X11-server to listen to the tcp port as described in Example 40–7.The VNC listen facility should be used with caution due to security considerations. Restart the service.# svccfg -s cde-login setprop 'dtlogin/args=""' # svcadm restart cde-login Add xvnc service to /etc/services if it is not already there.# printf "vnc-server\t5900/tcp\t\t\t# VNC Server\n" >> /etc/services Enable the Xvnc inetd service.# svcadm -e xvnc-inetd Connect from another machine and verify that you see the login screen and can log in to a desktop session.# vncviewer hostname:0 This procedure starts VNC at system boot from the dtlogin, displaying the dtlogin login screen. Become superuser, or assume the Primary Administrator role. Add an instance of x11-server service called display1 for configuration, and configure it to run Xvnc.svccfg -s application/x11/x11-server add display1 svccfg -s application/x11/x11-server:display1 addpg options application svccfg -s application/x11/x11-server:display1 addpropvalue options/server: "/usr/X11/bin/Xvnc" svccfg -s application/x11/x11-server:display1 addpropvalue options/server: '"SecurityTypes=None"' Configure dtlogin to start it. mkdir -p /etc/dt/config cp /usr/dt/config/Xservers /etc/dt/config/Xservers echo " :1 Local local_uid@none root /usr/X11/bin/Xserver :1" >> /etc/dt/config/Xservers pkill -HUP dtlogin Connect from another machine and verify that you see the login screen and can log in to a desktop session.# vncviewer hostname:0 Starting VNC manually displays the session of the user. A VNC password is required.A VNC password should be different from a UNIX login password. A VNC password is not securely encoded on disk or across the network. Do not use a valuable password. Start VNC manually.% /usr/bin/vncserver -httpd From another machine, open a web browser. Go to http://hostname:5802/.The number 5802 after the colon assumes that the VNC server said it was starting on display :2. If another display number was listed, change 5802 to 5800 plus the display ID. Enter the password you provided to the vncserver script. Verify that you see a simple desktop session in the viewer. Use the following to start the GNOME session.# /bin/sh # mkdir <your homedir>/.vnc # echo "#!/bin/sh\n/usr/bin/dbus-launch /usr/bin/gnome-session" > <your homedir>/.vnc/xstartup You can use the man command to view the man pages.man Xvnc man vncviewer man vncpasswd Live linkss to these man pages cannot be made from this book. The MANPATH variable is normally set for you in desktop login sessions. If the entry is not found, check your MANPATH environment variable and add the path to the X11 man pages if necessary. View the MANPATH:echo $MANPATH /usr/share/man:/usr/dt/man:/usr/openwin/share/man If necessary, add the path to the X11 man pages.setenv MANPATH /usr/share/man:/usr/dt/man:/usr/openwin/man:/usr/X11/man
