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 plug in my USB mp3 player/memory stick, linux mounts its perfectly, but I can't read the files on the stick. My dmesg says:
hub.c: new USB device 00:03.0-3, assigned address 1
WARNING: USB Mass Storage data integrity not assured
USB Mass Storage device found at 1
SCSI device sda: 251904 512-byte hdwr sectors (129 MB)
sda: Write Protect is off
cdrom: This disc doesn't have any tracks I recognize!
What does it mean that the disc doesn't have any tracks it can recognise? The filesystem of the stick is FAT16 if my memory serves me well, and Linux can read FAT16 can it not?
1. Get autofs package.
2. Edit conffiles of autofs.
3. Restart autofs.
4. Make convenient symlinks.
In debian, package containing autofs is called autofs; maybe something similar in FC.
Use your installation / package management tools to figure out.
I have a /etc/auto.master with line
The usage of this is similar to fstab. The /var/autofs/misc is an existing mountpoint where my autofs resides.
Other file /etc/auto.misc contains lines like
stick -fstype=vfat :/dev/sda1
Now running "/etc/init.d/autofs start"
(and "/etc/init.d/autofs stop" before it, if it was already running)
should do the trick.
if you cd to directory /var/autofs/misc/stick/, the autofs should mount the /dev/sda1.
And if you move away from there and/or stop accessing the stick, it will unmount the device after the timeout.
# $Id: auto.master,v 1.2 1997/10/06 21:52:03 hpa Exp $
# Sample auto.master file
# Format of this file:
# mountpoint map options
# For details of the format look at autofs(8).
/misc /etc/auto.misc --timeout=60
and then in my /etc/autofs.misc, i have :
# $Id: auto.misc,v 1.2 1997/10/06 21:52:04 hpa Exp $
# This is an automounter map and it has the following format
# key [ -mount-options-separated-by-comma ] location
# Details may be found in the autofs(5) manpage
cd -fstype=iso9660,ro,nosuid,nodev :/dev/cdrom
# the following entries are samples to pique your imagination
#linux -ro,soft,intr ftp.example.org:/pub/linux
#boot -fstype=ext2 :/dev/hda1
#floppy -fstype=auto :/dev/fd0
#floppy -fstype=ext2 :/dev/fd0
#e2floppy -fstype=ext2 :/dev/fd0
#jaz -fstype=ext2 :/dev/sdc1
#removable -fstype=ext2 :/dev/hdd
stick -fstype=vfat :/dev/sda1
I restarted autofs, and it says [ OK ]
and i tried to cd to /misc/stick and it says there is no such dir, so I try and create /misc/stick and it says :
[root@cpc3-cwbn1-3-0-cust242 /]# mkdir /misc/stick
mkdir: cannot create directory `/misc/stick': No such file or directory
dmesg shows only kernel log, not userspace events that are logged.
In some distributions (atleast some versions of RH), all logs are collected to /var/log/messages, in some(eg. in debian) to /var/log/syslog. You can try to locate the correct log by running command like
logger "Hello there, where are you?"
and searching through the /var/log to see what file got a line containing those words.
