Mounting pendrive and cdrom automatically

It i plug the pendrive or insert cd to cdrom it will be automatically mounted.
How would i do this?

I don't want to mount these manually from terminal.

You'll need to write udev rules to handle this. Found in /etc/udev/rules.d

Here's some reading to do:

Make sure you are a member of the cdrom and plugdev groups. Simply run the command groups to find out what groups your user name is a member of. For reference, here is what I get:

Code:

bash-3.1$ groups 

users floppy audio video cdrom plugdev power netdev

bash-3.1$

Flash drives and data CDs should mount automatically in Slackware 13 if you are a member of those groups.

Hi,

The mounting point can be controlled in the static '/etc/fstab' file.

'udev' & 'hal' should control the device itself. If you want to write rules for the 'udev' then look at 'Writing udev rules'.

The above link and others can be found at 'Slackware-Links'. More than just Slackware® links!

Should not flash drives and data CDs be automounted as I said in my post? They are for me. Or am I missing something here?

groups

Code:

groups: cannot find name for group ID 100

100 floppy audio video cdrom

But after inserting a cd if i click the cdrom from the left side column of pcmanfm i get messages:

Code:

You are not privileged to mount the volume "Softwares"

What is doing this for you is KDE I'm guessing. So if KDE wasn't running, no automount.

cola, it sounds like things have been tampered with. Group 100 is the "users" group, and it's not good that your system doesn't know that.

For the permissions subject,
Edit /etc/fstab and add the "users" option to allow normal users to mount it.

Post your /etc/fstab. Make sure the entry for your CDROM drive looks something like this:

Code:

#/dev/cdrom /mnt/cdrom auto noauto,users,ro 0 0

Since you are a member of the cdrom group, if fstab has users in the options column it should allow you to automount data CDs.
Note that the entry for cdrom is commented out since hal and udev mount CDs automatically.

I don't know why you get this when you run the groups command:

Code:

groups: cannot find name for group ID 100

I don't see that when I run groups.

Well in my case it is XFCE. Anyway, thanks for clearing that up for me.

Just change the owner option in your fstab to users and you should be able to automount data CDs. You will need to reboot the computer for this to take effect.

This will make you able to mount them, not necessarily automount them. And no restart is needed, mount will check /etc/fstab each time it is called.

You are right.It will mount after clicking the cdrom,but not automount.

Look above, the link has been posted twice. Writing udev rules will take care of this.
