How to Connect OpenSolaris to Solaris 10 Using Gnome Display Manager (GDM)

I administer a number of Solaris 10 servers, and today I finally bit the bullet to figure out how to connect my OpenSolaris 2009.06 Ultra 20 WS to them. I wanted to be able to remotely connect to them and do system administration on them without having to wander to the server data center. So here is how I configured Gnome Display Manager (GDM) to do it.

1. Modify the custom.conf file  located in /etc/X11/gdm
   
   You will need to add the following:
   
   
   

   [xdmcp]
   Enable=true
   [security]
   DisallowTCP=false
   

   
   
2. Next we need to modify the x11-server configuration to allow TCP connections.
   
   
   

   svccfg -s x11-server
   svc:/application/x11/x11-server> setprop options/tcp_listen=true
   svc:/application/x11/x11-server> quit
   

   
   
3. Restart the server
   
   Note: The next command will log you out of the server so make sure that any work you have is saved before executing it.
   
   
   

   svcadm restart gdm
