Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

When I insert a known USB stick in my laptop, it does not show anymore in the "Device notifier" of KDE.
When I select show "All devices" or "non-removable devices only" it does show. But when I select "Removable devices only", it does not.
Previously, it did show.
I did not change anything, as far as i know.
When you insert the USB stick in the computer, type dmesg in a Konsole window. Your stick should
produce messages "New USB devices...". Also, there should be messages [sdx] telling you that
the stick has the associated device file /dev/sdx[1-n]. /dev/sdx1 is the first partition (the whole
stick if you have not partitioned it). You should then check the /etc/fstab and /etc/mtab for lines
Normally, mount -t vfat /dev/sdx1 /mnt should mount the device, umount /mnt unmount it.
Are you using some kind of automounter daemon that mounts automatically the removable devices (I am not using
Fedora, so I have no idea of their default configuration) ?
Are you sure this daemon has not been updated recently (automatic security upgrade) ? Can you check that with rpm ?
You must look at the file /etc/fstab. The fact that KDE asks for a root password for mounting a drive
indicates that mounts by a regular user are not permitted.
Normally, if mounts by regular users were permitted, you would see a line:
/dev/sdb1 /media/memory1 auto user,noauto 0 0
In that file. The first entry is the device file associated with your USB stick, the second entry is
the mount point, the third one ("auto") stands for filesystem autodetection, the fourth entry user,noauto
indicates user mounts are permitted, and mount should not be done at boot time. You can do man mount for
To mount without root password add that line (as root) to your /etc/fstab . You may also search
the forum for indicating devices by UUID or label in /etc/fstab.
