Hello folks,
I have a backup script for my computer running ubuntu 8.10. The script itself is great. It maps the drive and everything but during a shutdown in ubuntu i seem to hit a little bit of a glitch. When shutting down/rebooting the pc seems to hit a hangup point. It shows the ubuntu splash screen, then it shows this on a blank screen:

acpid : exiting
[259.882553] CIFS VFS: SERVER NOT RESPONDING

[259.525205]CIFS VFS: no response for smd 50 mid 11174

To that end i have discovered that this is to do with the mounts not closing properly. So what i want to do is create a script that will automatically unmount the network shares when the pc either a user logs off or the machine shuts down or reboots. The only thing is the umount command requires root, and i want this to happen automatically. But i have no idea how to begin. I know how to configure the umount command however. If someone can explain to me how to create a script that will run when the user ends their session or reboots/shuts down a pc. If someone could tell me where to start it would be appreciated. Like i said the script needs to run as root so the umount will function.
Thanks for all the help in advance.

Hi new tech guy,

First, run the command:
[as a regular user]
ubuntu@ubuntu:~$ sudo fdisk -l
Then run the command:
ubuntu@ubuntu:~$ mount
The first command will tell you what the device names are of the hard disks in your system, and the second command will tell you which hard drives are mounted.

For automating which drive to unmount, you need to discover the device name of the mounted drive, and issue as root, the following command with the hard drive's device name:
root@ubuntu:~# umount /dev/xxxx
[where xxxx is the device name/partition name of the hard drive which is mounted which you get from the output of the first command for mounted devices from the second command]

As a sidenote, i found a file called .bash-logout. Would that be the file i need to edit with the command? I already know where the directory is. It is a network share in /mount/Username (where username is respectively the name of the user) and /mount/Public (a sharing directory on the network). How would these automate so a user would not have to enter a root password? They are not in the fstab file by the way as they are mounted by a shell script at logon.

Hi new tech guy,

Have you looked at the contents of .bash_logout?
$ cat .bash_logout (from the user account).

Use the sudo command preface to execute any commands (as root) from the user account (that require root user priviledge), like this:
$ sudo umount /dev/xxxx

-- Tom

This is the output i get from that command: Would i just add the sudo umount command.
~$ cat .bash_logout
# ~/.bash_logout: executed by bash(1) when login shell exits.

# when leaving the console clear the screen to increase privacy

if [ "$SHLVL" = 1 ]; then
[ -x /usr/bin/clear_console ] && /usr/bin/clear_console -q
fi

Would i just create a blank line with:
sudo umount /mount/Username
sudo umount /mount/Public
?

I tried adding the command to the end, with no avail. Still get the hangup bug when i select to reboot the system. Would another option to possibly somehow remove the shutdown buttons from gnome and replace them with my own shutdown shell script?

What is the full output of the following commands:
$ sudo fdisk -l
and
$ mount
