Connecting to OpenIndiana by XDMCP Enabling XDMCP in OpenIndiana I have a small NAS which I have built which run's OpenIndiana oi_151 and I wanted to be able to headlessly administer it, whilst I have SSH and thats all I really need, sometimes its nice to use a remote desktop environment. XDMCP is a fundamental part of the X Window System, and one feature it offers is the ability to export your display across a network. To enable XDMCP on OpenIndiana simply modify the XDMCP section in the file /etc/gdm/custom.conf so that it looks something like this - # GDM configuration storage [daemon] [security] [xdmcp] Enable=true [greeter] [chooser] [debug] Now you just need to restart the GDM service - $ sudo svcadm restart gdm Thats all there is to it! Testing the XDMCP Connection To connect to the XDMCP server, you need an X Server for your client machine, for Windows you can use Xming, or if you are on a Linux/Unix like platform you could use Xephyr, Xvfb, Xnest or similar. Personally im on MacOSX and Xephyr works very well for me - $ Xephyr -query mnemosyne OpenIndiana XDMCP Mac OSX Xephyr Solaris
