CD/DVD writer
by Chris Carlson
I'm using Fedora 9 on a "AMD Athlon(tm) X2 Dual Core Processor
BE-2350". The system (an eMachines computer) came with a CD/DVD
read/write drive (Optiarc Model: DVD RW AD-7200A Rev: 1.W1). When I
load a blank DVD-R in the drive, an icon appears that tells me I've got
a blank DVD in the drive. I double-click the icon, and CD/DVD Creator
pops up. I drag/drop files into the window and then tell it to "Write
to Disc". It thinks for a while, then pops up a little window with the
very clear and informative message, "Error!" I can find no information
on what the error is or what I can do about it.
Thinking that the brand of CD/DVD writer was the problem, I installed an
older drive that I had from a previous computer (TSSTcorp Model: CD/DVDW
TS-H552B Rev: TS02). I get precisely that same results.
I have also tried installing a blank CD-R. This works somewhat similar
but doesn't even provide me an "Error!" popup. I see something pop up
quickly and immediately disappear, but nothing seems to be written.
I've tried this with both drives as well with identical results.
After discovering my sound didn't work because of a security setting,
I'm wondering if there is some security setting for writing CDs/DVDs.
I've modified all my /dev files related to the two drives to rw-rw-rw-,
but that doesn't seem to help.
I put a DVD-RAM disk in the Optiarc drive, and I was able to copy a gob
of data to it. It's unreadable by Windows, but it proves to me that the
drive writes.
Both drives can read CDs and DVDs without a problem.
Below is the info determined by the kernel for the two drives (sr0 is
the TSSTcorp drive and sr1 is the Optiarc drive).
cat /proc/sys/dev/cdrom//info
CD-ROM information, Id: cdrom.c 3.20 2003/12/17
drive name: sr1 sr0
drive speed: 48 48
drive # of slots: 1 1
Can close tray: 1 1
Can open tray: 1 1
Can lock tray: 1 1
Can change speed: 1 1
Can select disk: 0 0
Can read multisession: 1 1

Can write DVD-R: 1 1
Can write DVD-RAM: 1 0
Can read MRW: 1 1
Can write MRW: 1 1
Can write RAM: 1 1
Are there any settings or other places I should look for a problem? Is
this a Fedora bug? I'll file a bug if I'm not the only one seeing this
problem.

Wireless problems.
by Mark Haney
I've had this F8 box working perfectly for the last 4 months or so and
for some reason now (and I assume this is due to the last round of
updates, but I don't know for certain, my wireless link (linksys 54g
card) refuses to come up and connect. In dmesg I get lots of 'link not
ready' messages. And even though the card was set to startup on boot, I
had to unset and reset that option to make that work.
Even when I manually set I set it up, it doesn't want to come up. The
module is loaded, it just isn't behaving. Could it be kernel related
perhaps? I don't know where to start debugging this, since it all LOOKS
right.

where's the filesystem?
by Nelson Strother
A Fedora9 system with the default layout of the / filesystem on LVM
was running, nearing the end of a packagekit update that was
installing six small bugfix updates. With no warning, the system
powered off. The electric supply was not interrupted, e.g. the UPS
did not chirp. Smartd has offered no complaints about the hard disk
drive. The filesystem was less than 60% full. Interesting.
On a few attempts to restart the system, running the same Fedora 9
system that spontaneously powered down, grub and boot sequence proceed
normally until just after the message "Starting udev" is displayed.
Then the system spontaneously powers down with no other message or
warning.
The system will successfully boot from a Fedora 9 system installed
on another partition, with a custom layout with the / filesystem in an
ext3 partition without LVM. Obviously, the first thing I would like
to do is to mount the / filesystem of the failing system, but attempts
to do so provide puzzling results. At the moment, the only LVM
visible to this system is the one containing the failing system. All
of the LVM queries seem to show it to be in good health, e.g.:
[root@localhost ~]# vgscan -v

How to find and clear zombie processes w/o rebooting?
by Dan Thurman
Using F8, I have found that Nautilus sometimes hangs and
runs at 100% CPU. Force killing Nautilus's drive windows
was the only way to recover. I am not sure that force killing
this drive window is related to the zombie that I founding using
top.
I also discovered that my swap was increased to 2GB of 4GB
and has stayed there ever since.
So before I accuse Nautilus as being the zombie process, how
do I locate it using ps or some other tool to find out what is
going on and to what process the zombie was?
In the same breadth, is there a way to clear zombie processes
without being forced to reboot the system which would certainly
remove the zombie process and clear the swap space?
Thanks!

Fedora-DS alias dereference problem.
by Sergey Kamshilin
Hi all,
I'd like to report it as a bug because I could not find any help on
forms neither in other sources...
Hi all,
It appears that Fedora-DS 1.1.0-3 does not dereference aliases even if
it asked for. So I have a simple example:
============
# ldapsearch -x -LLL -b "ou=Special Users,dc=lab,dc=convedia,dc=com" -a
always
dn: ou=Special Users,dc=lab, dc=convedia, dc=com
objectClass: top
objectClass: organizationalUnit
ou: Special Users
description: Special Administrative Accounts
dn: aliasedobjectname=ou\=DNS\,dc\=lab\,dc\=convedia\,dc\=com,ou=Special
Users
,dc=lab,dc=convedia,dc=com
aliasedObjectName: ou=DNS,dc=lab,dc=convedia,dc=com
objectClass: alias
objectClass: top
===============
Instead of "dn: aliasedobjectname=..." I would expect to see a DNS
subtree (DNS object).
Couple lines may be wrapped but the idea is that parameter -a always is
ignored. Is it a known issue? Is there any workarounds?
Thank you in advance,
SergeyK
