Notes on OpenSolaris: VNC config

Although most of my boxes are hooked in to a KVM I like to be able to access their desktops via VNC and XDMCP. Here are the steps to enable VNC on port 5910 and XDMCP on OpenSolaris 200805.

Step 1: Enable XDMCP using gdmsetup.

Become root and run "gdmsetup".
Enable Remote access with style "Plain".
Under the Security tab disable "Enable Automatic Login" and clear the "Deny TCP connections to Xserver" box.

Step 2: Fix up the config for xvnc-inetd (if necessary

maurice@ra:~# svccfg -s xvnc-inetd
svc:/application/x11/xvnc-inetd> setprop inetd_start/exec = astring: "/usr/X11/bin/Xvnc -inetd -query localhost -once securitytypes=none"
svc:/application/x11/xvnc-inetd> quit

You can limit the number of console logins to one by tying the server to a single display


maurice@ra:~# svccfg -s xvnc-inetd
svc:/application/x11/xvnc-inetd> setprop inetd_start/exec = astring: "/usr/X11/bin/Xvnc :1 -inetd -query localhost -once securitytypes=none"
svc:/application/x11/xvnc-inetd> quit

Step 3: Add the service to /etc/services.

maurice@ra:~# echo "vnc-server      5910/tcp" >> /etc/services

Step 4: Activate the service

Step 5: Restart gdm: Warning this will close all graphical consoles

maurice@ra:~# gdm-restart
