Hi All,
I have created a CentOS 6.5 OpenStack image using kickstart. I have noticed that when connecting directly to the Virtual Machine's console (think connecting directly to the physical machine) all of the system-config, firewall configuration, application update and install GUI applications work fine and prompt for root login when executed. Hoever if I connect to the VM using xrdp with a tiger-vncserver backend the apps either do not work, or take several minutes to prompt for the root password.
Here is a post I made in the forums that has no response: https://www.centos.org/forums/viewtopic.php?f=13&t=45307&sid=865afae...
It looks like my problem may be that when I do a ck-list-sessions the device/terminal information does not seem to be known: Session2: unix-user = '500' realname = '(null)' seat = 'Seat2' session-type = '' active = FALSE x11-display = '' x11-display-device = '' display-device = '' remote-host-name = '' is-local = TRUE on-since = '2014-03-06T17:23:07.718097Z' login-session-id = '4294967295'
I have tried disabling selinux, modifying the startwm.sh script included with xrdp to launch the session with "ck-launch-session gnome-session".
Neither seem to help.
Does anyone have any idea what might be going, or an explanation of how authentication works when one of these apps requires root permission?
Most of the /usr/bin/system-config-* are symlinks to /usr/bin/consolehelper.
My recommendation is, instead of trying to get a graphical console, SSH into the instance. You'll need to know/set a root password, have your SSH client configured to forward X11 (as well as the sshd on the remote VM), and be running an Xserver on your local system, but that way, you'll have the graphical version coming to you, directly. Because it's running via consolehelper, it will prompt you for the root user's password, and you'll be off to the races.
