udiskie and user permissions

Message

mikegpitt · Post by **mikegpitt** » Tue May 17, 2011 12:08 am

Following the removal of hal from my system I installed udiskie, but things aren't working as they used to. One issue I'm having is that only root running udiskie seems to have the correct permissions to mount a device.

Code: Select all

$ udiskie

failed to mount device /org/freedesktop/UDisks/devices/sdb1: org.freedesktop.UDisks.Error.PermissionDenied: Not Authorized

My user is in the usb and plugdev groups. Not sure what else to check. Any ideas?

Code: Select all

$ groups     
wheel audio cdrom video games cdrw usb users vboxusers plugdev mikeg vmware wireshark

did you install and start consolekit ? udiskie needs to run within a consolekit session to assign usage of a usb device to a specific session (and throuhg that to the user owning the session)

This is a good thought, although I think it is running. I didn't place consolekit in any runlevel, so I figured I'd start it up manually, but get this:

Code: Select all

# /etc/init.d/consolekit restart
 * Starting ConsoleKit daemon ...
 * start-stop-daemon: /usr/sbin/console-kit-daemon is already running                                                                          [ !! ]
 * ERROR: consolekit failed to start

ps does see it running though:

Code: Select all

# ps -aux | grep -i console-kit
root     23719  0.0  0.1  27240  2944 ?        Sl   May16   0:00 /usr/sbin/console-kit-daemon --no-daemon

Although, I don't see it listed as starting in rc-status, despite the message above:

Code: Select all

I also tried to manually start it as root, and it forked to the background without error. No change on mounting a USB stick as a user though.

Well, first of all, I see you are still running hald. At least try tohave that service stopped.

Next, I did not really mean starting the consolekit daemon, but instead making sure that whenever you log in or switch between users, this is announced to the consolekit daemon.

E.g. I am currently running xfce, and changed
/usr/share/xsessions/xfce.desktop to include
Exec=ck-launch-session startxfce4

If this is needed, depends on your complete environment. E.g. I believe that it is required when starting sessions from xdm, but that kdm and gdm do the equivalent of 'ck-launch-session' automatically.

I think you are onto something here... I use xdm and fvwm as my wm. I use the file /etc/env.d/90xsession to start fvwm by default system wide.

The contents are currently:

Code: Select all

XSESSION="fvwm"

I tried to add ck-launch-session here, but it wouldn't start fvwm. There was no corresponding file in /usr/share/xsessions/, so I decided to create one manually, hoping that xdm would somehow see this, but this also didn't work.
