kdesu and umount cd

[senorian]

Back in April( on: April 23, 2007, 10:24:12 am ») I asked about this but only as an addition to my main question.
Problem
I have been unable to umount and eject from my dvd/cd reader except by rebooting the computer.
Today I noticed that , on right clicking the desktop cdrom icon it said owned by root.
So i opened the "run command" window and typed
kdesu umountcdrom0
It asked for my password
I then went to the desktop, clicked on the eject button and it worked.
BUT
I could no longer access the net.
I seem to remember reading something about the root system only staying in operation for 15 minutes; so I waited 20 minutes in the hope that I could again access the net
NOGO.
I disconnected the power to the dsl modem and to my router and then reconnected
ALL now OK.
Is there some other command that I can enter which will umount my cd without cutting my net access?
thanks

Re: kdesu and umount cd

Verify that in User Management cdrom is included in the secondary groups for your user account.

Re: kdesu and umount cd

KMenu>System Settings>User Management, click the Administrator Mode button, highlight your user, click the "Modify" button, and in the window that opens, find "cdrom" in the left column, highlight it, and click "Add -->" to add it to the user.

Thanks
I have in "system setting" no" user management" .
I do have "user and groups"
clicking on this I find my name already highlighted.
I click on "modify" and can only find "cdrom" in the primary group listing.
I highlight it but there is no add button.
There is a "secondary group horizontal listing and if I click on the "select button" 2 drop down menus appear; one called" available groups" and the other "seleted groups"
No cdrom listing
What am I doing wrong?
thanks

Managing Group Access ->

Grant use of a device to system users:

The first example will be of granting access to a device, the CD-ROM. This is generally not done for regular users on a server. Server access to a CD-ROM is limited to root by default. (This example may also be applied to the diskette. Group: floppy, first floppy device: /dev/fd0)

1. Grant mount privileges to system users
2. Create group cdrom .
3. Allow use of device by group cdrom .
4. Add user to group cdrom .
