ltsp-update-image is used when you update the chroot, like when you: - activate the root account, change it's passwd - install ssh, vnc, etc. or any application in the chroot, that must be run by the thin client hardware - do an apt-get uprade - install a backported driver - other cases > If the thin-client just gives the display with Keyboard and mouse, why > should it mount usb's inserted on the server, The thin-client doesn't mount anything. Try thinking like this: When you ssh to your server, from your home, you can mount and umount the server's disk or partitions. Your computer doesn't mount anything on the server. > coz on the server some > other user account has logged in and his permissions should be in > place and not of the user account on LTSP client, isn't it? But if you plug something on the server, if it is not yet mounted, any user can mount it (if he is in the right group). Something is not clear: who mount the usb stick ? only one user at a time can mount it. > I am sorry > if this is sounding very basic.

It's not opened on the client, but on the server. You opened it from a server's user account. Even if that user login from a client: users are allways logged in on the server. In other words: It doesn't change if the user is logged in to the server from a client. > Me just discussing, thanks a ton you welcome Xavier [email protected] ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
