Hardware :: Dvd/cdrom Keeps Spooling Up When Polled (apparently)
May 7, 2011
I'm using Slackware 13.1 on a new laptop (MSI 1481). Everything has worked great except when I put a DVD in the drive (like the Slackware DVD) the drive spools up and down constantly - you know, how it goes from slow speed to fast speed. I figured it was hal polling it every 2 seconds and that for some reason it was causing it to actually kick in and read the DVD, but disabling that didn't help. I've also tried not starting X or xfce (going to runlevel 3) but that didn't make any difference - as soon as I put the dvd in, it starts up.
It's not just the Slackware dvd either, it's any DVD. Movie DVDs however don't seem to spool up to higher speeds but you can still hear the drive running constantly, so there is some different. I'm not mounting the drive or anything, just close the tray and listen to the rhythmic annoyance of the drive at full speed, then not, then full speed, then not.
I don't see any other suspect processes with top or ps either. Anyone have any idea why this would be if it's not the polling doing it? I'm starting to think a kernel or hardware thing. The drive I have is reported by cdrecord -scanbus as "Optiarc DVD RW AD-7580S FX20".
I'm at a loss. I'm thinking next I'll have to install another distro to at least rule that out, but with so many variables (packages installed, kernel version, driver versions) I don't know that this approach would tell me much.

I've been trying to figure this out for longer than I care to admit. We upgraded our print server (sysadmin) to 64 bit lucid and that moved our cups server from 1.3.7 to 1.4.3. We have a remote server that is still 1.3.7 (printhost1) but version difference doesn't seem to be relevant to the problem.
If I'm on console on sysadmin and do an lpr to a printer on printhost1, everything is copacetic. However, If I'm on a host that specifies "ServerName sysadmin" in its "/etc/cups/client.conf" access_log on sysadmin shows:
172.16.10.52 - - [22/Mar/2011:11:11:40 -0500] "POST /printers/103_hp4250 HTTP/1.1" 200 306 Create-Job client-error-not-authorized
and error_log shows:
E [22/Mar/2011:11:11:40 -0500] Returning IPP client-error-not-authorized for Create-Job (ipp://localhost:631/printers/103_hp4250) from 172.16.10.52
We've been using this method of sharing printers between locations for years and years so it not working now is a surprise.
cupsd.conf on sysadmin looks like this and is as open as I can imagine:
ServerName sysadmin
ServerAlias *
ServerAdmin webmaster
FileDevice Yes
SystemGroup staff
LogLevel info
code....
Additional symptoms are that only printers locally defined on sysadmin show up when the client uses System>Administration>Printing in gnome. Same thing when you browse printers in windows on our samba domain controller that backends on CUPS.
I just know that it's something simple that's going to make me facepalm but I'm at a loss.

I have the following set up in my crontab:
Code:
# crontab -l
# m h dom mon dow command
*/5 * * * * /usr/bin/perl /usr/local/bin/perl/managed_arp_data.pl >> /var/log/arpdb.log
*/5 * * * * /usr/bin/perl /usr/local/bin/perl/infoblox_fixed_sync.pl >> /var/log/crossref.log
00 23 * * * /usr/bin/perl /usr/local/bin/perl/infoblox_host_sync.pl >> /var/log/host_sync.log
0 * * * * /usr/bin/perl /usr/local/bin/perl/infoblox_excl_sync.pl >> /var/log/excl_sync.log
None of these jobs is apparently running, however they did run on the 31st (yesterday), but not on the 30th or any other day during the last 10 days that I have logs for. I think I've set cron to run at log level 1, but I don't know where that log goes, I don't see anything like /var/log/cron
So, couple questions:
* If I do something like "sudo -s" to get a root prompt and then do a "crontab -e", which user does that crontab get executed as?
* Where should I look for cron logs?
* Anyone know why a job would run on the 31st, but not any other day?

I have an issue with cfservd, from the cfengine package not listening on both ipv4 and ipv6. Tracing through the source indicated that the issue was with the getaddrinfo() call. I have used the example code on the man page and can confirm that it doesn't work as expected on either Fedora 12, Fedora 10 or CentOS 5.3
The servers I am testing on have both ipv4 and ipv6 enabled and working. i.e. I can ssh to them using either -4 or -6 and netstat -a shows 0.0.0.0:22 and :::22
Running the example code on the Fedora servers results in only a single IPv4 address structure being returned by the getaddrinfo call and hence only listening on the one protocol. Strangely, on the CentOS server only the IPv6 address structure is returned.
I need both IPv4 and IPv6 for cfengine but am at a complete loss as to how to get it to work when the issue appears to be something fundamentally wrong at the OS level.

I have done some searching around and now know that the 64 bit version of Wine is useless. I tried to install the 32 bit version and apparently succeeded. The problem is that when I open Wine File the .wine-x86_64 folder reappears. I don't even know where the 32 bit folder is.
I have tried
Code:
yum erase *wine*
but it does not seem to work. However this does.

I have a user that is reporting the following error on a bounced message:
Quote:
smtp;554 5.6.1 Body type not supported by Remote Host
He is forwarding emails from his exchange server to a recipient in Germany relaying through our smtp server using Surgemail as the MTA.
He called a senior tech specialist at Microsoft to get help thinking the problem was on his end (exchange server). According to this "specialist", he said the problem was that our smtp server was not advertising 8BitMIME in its 250 statement. I tested this myself by log in on to the smtp server and doing typing the following:
Code:
EHLO localhost
250-smtp.<mycompanyname>.com. Hello localhost (127.0.0.1)
250-AUTH PLAIN LOGIN
250-DSN
[Code]....
As you can see, 250-8BITMIME is not listed here. From the bit of research I made, I found that most MTAs send this by default. Is it possible that the characters from the German language are causing this problem?
NOTE: This problem did not exist or was never reported until now. No one has made any changes on any settings on the server.

I've recently upgraded my Lenovo Sl500 laptop from windows vista to windows 7, both 32bit.
Prior to this i had dual boot between CentOs 5.6 and windows vista.
After i have upgraded to windows 7, the dualboot is apparently gone, I am no longer able to boot in linux.
My question is now, how can i fix this, or create a new dual boot?
Im currently left with two partitions, one with Windows 7 installed, and one with CentOs 5.6 installed, but as said, I am unable to acces my linux.

I have an HP OfficeJet 6500 wireless all in one.I've tried using the HPLIP that comes in the distro, uninstalling that and installing the scripted installer from the site, and manually installing the RPM.Yast isn't detecting my printer, whether I try a USB install or over the network.I have all the dependencies, CUPS is up to date, and this printer is detected by Fedora and Kubuntu.

I've followed the instructions that I can find as well as I can, but it seems I've hit a relatively unusual condition. Here's the preliminary stuff:
lspci output:
Code:
0b:00.0 Network controller: Broadcom Corporation BCM4321 802.11a/b/g/n (rev 05)
Subsystem: Apple Computer Inc. Device 008c
Flags: bus master, fast devsel, latency 0, IRQ 16
Memory at 97300000 (64-bit, non-prefetchable) [size=16K]
[code]....
Currently, the interface seems to be set up correctly in the YaST network settings thing, labeled as wlan0, and it doesn't have the 'Not Connected' indicator after it.
EDIT: iwconfig doesn't list wlan0; it just lists eth0 and lo0, saying neither have a wireless extension

I merged my toolbars into one toolbar. This results in having my bookmarks toolbar next to my URL bar.
The problems is that the URL bar apparently chooses the biggest width available with priority over the bookmarks bar, being merged into simply an arrow, which I have to click in order to see my bookmarks.
I would like to give my URL bar a fixed width so that I can see my bookmarks toolbar or to leave the URL bar with a flexible width as long as it doesnt have priority over the bookmarks bar.

I just ran Computer Janitor on my computer and I think it broke Synaptic. The program was cleaning up some files, but then it froze halfway through and I had to force it to quit. Since then, I can't open Synaptic package manager, the Ubuntu Software Center, nor Computer Janitor itself. When I do they either freeze and I have to force them to quite or they just don't show up on the screen, but they're stuck running in the background because System Monitor reports the processor is running at 100% and so I have to go in manually and kill the bad processes running in the background. Restarting doesn't change anything.Running Lucid Lynx on a HP dc7100, P4 3.2 Ghz, 2gb RAM.

I'm using Ubuntu 10.04 up-to-date in my laptop HP Pavilion dv4-1290br.My sound seems to randomly get muted, after a few hours the laptop is on. I've checked the volumes, I've compiled and installed the very latest ALSA driver, tested it trying to play music and changing the volume in hardware and software. Nothing works. The sound simply gets muted until I reboot.

I installed Ubuntu 5 days ago....looked great....seemed to offer everything I want. Then I clicked on the firefox icon and it brought up Google ...Great!....Then I said ..this is easy..I'll have a look at my share-trading dynamic platform. Searched for Commsec and clicked 'launch Webiress'...and then it hiccupped! I got a message saying I needed Java "Now downloading".....Okay I've had this happen in windows...no problemo.. Then I tried to follow the instructions contained on the download page from Java....thats what started my five days (30 hours now and counting) of misery.
Finally on one of the hundreds of Ubuntu pages I've read I found that there is a bug in java....that prevents it from working with the Firefox that Ubuntu provides. So I cleverly removed firefox ....and went to Mozilla and downloaded a new version 3.6 of Firefox.....followed the instructions at Sourceforge.net (and other places I can't remember). Now I have Firefox in a folder in 'Documents' with libjavaplugin_oji.so linked to ///java/jre.6.0_21/plugin/i386/ns7... But when I try to fire up Webiress I still get the messsage "Java not installed ...now downloading".

I'm experiencing an occasional frustration using Evolution with my work email which is on an MS Exchange 2003 server.Everything usually works well enough, but from time to time I'll try to retrieve a message,Is there a setting I've missed in Evolution that might take care of this, or some other workaround?Let me re-emphasize that the server is a 2003 Exchange server (and a source of endless frustration for a non-windows user). It's not a 2007 or 2010 Exchange server, which is what most companies use these days.

I have a 3ware controller that has a RAID 1 of two SATA disks.After an outage, the linux box (which is running ubuntu), restarted and the partition is now mounted read only. I only have the "/" mount point (this is a test server).Now, if I go to the 3ware controller by pressing ALT-3 while booting, I don't see any indication that there is something wrong with the disks.If I let the computer boot, I'm asked by fdisk if I want to fix/ignore/etc the inconsistencies found.

I downloaded a program called tonespace http://www.mucoder.net/en/tonespace/ which I extracted and then tried to execute the executable file with ./tonespace. This gives me the following message:
bash: ./tonespace: No such file or directory
When I use the command: file ./tonespace I get this: tonespace: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, stripped
I dont get it. The file is clearly there, yet when trying to execute it bash doesn't seem to recognize it.
It has permissions rwxr-xr-x and is not owned by root. Am I overlooking something?

This seems to be a variant of a problem many people have had, but after several hours trawling through various forums, I haven't seen a reliable match for my situation.In brief:Adding a third boot partition (of Ubuntu) to my existing dual boot of OSX 10.6 and Windows 7 seems to have crippled the Windows boot from working, because Grub apparently takes over the process. Yet Grub does *not* appear to be on the Windows partition.
More verbose:I have an older MacBook Pro (3.1, running Snow Leopard) that I recently refitted with a new 240GB SSD HD. With the extra space (it was previously only 120GB) I decided to add a dual boot with Windows 7 using bootcamp. This all went swimmingly well.Encouraged, I decided to follow this Lifehacker article's suggestion and triple-boot the machine with Ubuntu (I'd never used Linux before):So I now have the nice rEFIt boot partition selection screen, and, indeed, I'm up and running in Ubuntu, and enjoying it.
Only one problem: I can't get into Windows any more. If I try to go in through rEFIt *or* by holding down OPT at startup and selecting the windows partition directly, the result is the same: I get thrown into Grub's selector, and selecting the Windows partition from there leads to an error message and a dead end.Having read through numerous postings, I get the impression that Grub is doing something or living somewhere that it ought not to be, but in most cases I've seen, people had accidentally installed Grub onto the Windows partition (or indeed onto EVERY partition). So far as I can tell, this isn't the case with me. Here's my boot summary:

trying to get everything set up in Debian lenny on my new Toshiba staellite L500. I have successfully installed the wireless drivers and graphics card and have them both up and running. But I'm having trouble with the sound card. Specifically, it appears to be installed but I cant get any sound or any devices related to sound (speakers, volume control, alsamixer) to work at all.

I created 2 virtual machines with VMware Workstation 7. They have identical hardwares. One guest is CentOS 5.6, another is Mandriva 2011.
When I try to mount the cdrom in guest OS, in CentOS, I should execute
mount /dev/hdc /path/to/mount
in Mandriva, I should execute
mount /dev/sr0 /path/to/mount
I also remebered in some other Linux variant, I had to use
mount /dev/cdrom /path/to/mount
What's the difference between hdc, sr0 or cdrom? Is there a consistent way to mount cdrom in all Linux variants?

This is to do with accessing Dos era CD rom under Linux.The characters in directory and file titles appear as "chinese".As I know that I've loaded and installed programs from these CD roms onto a Windows 2000 machine, I'm wondering why I can not read the file names now. They are definitely in English.I've research and found the mount -o "characterset" but I shouldn't need to do that as they are not foreign language CD roms.The only other thing I can think off is that they are both degraded, but I would not have expected that of commercial CD roms.

I am using Suse since 6.5. I am no linux-expert, just power-user for years (no windows, no MAC OS X) at 3 computers at home and at work.
I just did two bare-bone-installs from up-to-date dvds with opensuse 11.3 at two almost identical Dell Inspirion 6400-Laptops. Clear, flawless installation without any workarounds... Same install at a Dell Desktop Computer without any problems. Automatic updating.
But both Laptops are having problems to read and show inserted data-cdroms. Knowing from the old versions and the new opensuse 11.3 at the desktop-PC what should happen, I have no clue what to do.
It is definitely no technical problem:
- the name of the inserted data-cdrom can be seen in k3b
- inserted dvds are triggering the correct action (!) (suggestions are shown what to do with the dvd; cdrom: no results, no suggestions, just a short and proper working of the cd-device itself can be heart)
- the data-cdrom can be mounted manually
What did not help:
- inserting a data-cdrom as root
- changing the permissions of non-root-users
- several updates of opensuse 11.3
- reading several forums (the answers go into the directions newbee-who-does-not-know-how-openuse-works, wrong-installation, wrong-updating-of-an-old-opensuse-version, geek-how-screwed-up-his-installation-with-manual-wrongdoings => nothing which helps in my situation)
This is my hardware-info about the cdrom/dvd-device:
