CentOS - Aug 2007 - Automount configuration problem

I have a simple automount configuration problem. I've done two similar,
clean, Custom installations of CentOS 5.0, on two similar, but not
identical boxes. On my box, automount is working perfectly. On my
daughter's box, it's not working. If I put the FC6 DVD into the drive in
my box, I can see the contents of the DVD, without any problem. If I
cat /etc/mtab in my box, I see this line:
/dev/hdc /media/FC_6\040i386\040DVD iso9660
ro,noexec,nosuid,nodev,uid=503 0 0

In System > Preferences > Removable Drives and Media, in both
boxes, for Storage tab, the 3 top boxes have check marks.

Mounted on /media.

On my daughters box, nothing in /media.  It's /dev/hdc.

Question: What configuration file do I need to change, in her
box?

TIA! Lanny

The problem is not only when logged in as root. I did that (su - and
then: mount /dev/cdrom /media) and I was able to install the Package I
wanted. My question remains, what configuration file do I need to
change, to get automount  to work correctly on that box? (The same DVD
was used to install CentOS 5.0 on my box and my daughters box). I use
GNOME on both boxes. Works perfectly on my box.   TIA, Lanny

Joseph: Thank you for replying. Before I added that line to the /etc/fstab
file in my daughters box, I did a "yum update autofs". No joy. Then, I
added that line to the /etc/fstab
file. No joy. Possibly, if I do some more research, I can figure out what to
change your
suggested line to. However, in my box, there is nothing like that in the
/etc/fstab
file and automount works perfectly. I would like to know what is putting this
line into the /etc/mtab file in my box, when I have
the CentOS DVD in the drive:

/dev/hdc /media/CentOS_5.0_Final iso9660 ro,noexec,nosuid,nodev,uid=503 0 0

Whatever is causing that line to be added to /etc/mtab apparently makes the
automount work properly.  Lanny

Akemi: Thank you. I will read that page, carefully. I have one other
idea: I have only tried this with GNOME. Both boxes also have KDE
installed. I want to try it with KDE, to verify that it is an automount
problem and *not* a GNOME problem. Lanny

Akemi: I just found the below, in the Enterprise Linux Deployment Guide
found in System > Documentation on the GNOME Desktop. In my box,
everything in the /etc/sysconfig/autofs file is commented out. When I
can use my daughters box (my wife is on it now), I will check to see
that everything in that file is commented out there too. Lanny

The default value is 1 (true), and allows for compatibility with the Sun
automounter options specification syntax.

I tried it with KDE on that box. Same problem. So, it *is* something
with automount and not a problem in GNOME. I looked at
the /etc/sysconfig/autofs in that box and everything is commented
out, like on my box. I will be studying the above web page!

Thank you for joining in! I know that you know what you are talking about, but,
I
don't know what to modify the Subject to, at this time. After reading the
Wiki page
Akemi referred to, I tried this on the box with the problem and on my box, where
it
works perfectly:

[mailing-lists at dell2400 ~]$ gnome-volume-manager
[mailing-lists at dell2400 ~]$ gnome-mount
gnome-mount 0.5

The results were identical on both boxes.

I saw the above line in the updated Release Notes from Upstream
yesterday and I was able to mount the FC6 Install DVD, as root from a
terminal, and then install the kdeedu package from that DVD, without
problems yesterday.

Then, last night, I tried to view the contents of the CentOS 5.0 Install
DVD and no luck.

This morning, I got the following results, with the FC6 Install DVD on
that box:

(1) mount - No medium found

(2) rebooted into Win ME and there was no problem 

(3) took out the DVD, rebooted to CentOS 5.0, inserted the FC6 DVD into
drive.  # mount /dev/cdrom /media
mount: block device /dev/cdrom is write protected, mounting read only
and I was able to view everything on the DVD, without any problem.

I'd begun to think possibly there was a problem on the Teac DVD drive
and that I should look for TEAC DVD Diagnostics, but it seems to work
properly.

Any ideas? TIA, Lanny

Johnny: It shows up properly, if I put a CD into that drive, but not
with a DVD in the drive. (On my box, a DVD works properly, all the
time).

I did   #rpm -V gnome-mount   and there was no output, so I believe
gnome-mount is OK.

If I boot that box, with the CentOS 5.0 install DVD in that drive, it
comes up to the install screen, every time. There does not seem to be a
problem with it mounting and reading the DVD, when it is booted.

I am wondering if somehow I screwed up the file permissions or settings
(running SELinux in Permissive mode and the Firewall, as on my box) that
are in some file unknown to me.

Thank you for writing! I get the Digest ML, and I just read your reply.
