That is not a valid HP-UX command. At least not that I know of.

Could they have an alias set up something like

alias mt_cd="mount /dev/dsk/c?t?d? /cdrom"

Hello,
But you cant mount a cd unless you have a user id of 0 wich is a superuser that is just as powerfull as root.

What is it that your user wants to do ?

If it is mounting a CD as the others suggest, you can configure the automounter to do that for you. The CD will be mounted when the user accesses the mountpoint and will be unmounted after a certain time of inactivity.

I think that's it!!
Some users want to be able to mount and umount CD's whenever they want, so they don't have to call me each time to do that.
How can i configure this auomatically as suggested before with automounter??
Thanks

Hi tarek,

Create a file in /usr/bin with the mt_cd and have this entry in that file
mount -r /dev/dsk/c?t?d? /cdrom

Here c?t?d? is the device file name for the Cdrom as shown be "ioscan -fnC disk"

Change the permission of the file to 755. your users should now be able to use this command to mount the cdrom.

Hope this helps.

thanks

Thanks Sanjay for your help, but unfortunately it isn't working. I created the file /usr/bin/mt_cd and i've set the permissions to 755, but while a user execute it, he will have this error:
mount: must be root to use mount
any further help?? Thanks very much.

Hi, tarek
your user might have wanted a script to mount the cd instead of issuing command.
put the CD mounting command in a file and add in PATH.

You could also use sudo to do this.

Sudo allows non-root users to run commands, as set up by you, as root without knowing the root passwd.

You can get sudo here:
http://hpux.cs.utah.edu/hppd/hpux/Sysadmin/sudo-1.6.2b1/

Once that is done, you could set up the mt_cd script as something like:

sudo mount /dev/dsk/c?t?d0 /cdrom

The script and users would then need to be set up in the /etc/sudoers file and then when the user enters mt_cd, they will be prompted for their password and the cd will be mounted.

You should probably also set up a umt_cd script with something like:

sudo umount /cdrom

so that the user can also unmount the cd when they are finished.
