Lightscribe
by Robert 10 Feb '10

10 Feb '10

I just bought an HP DVD Writer 1040r (as identified by k3b), an external USB-connected CD/DVD burner. The drive gets assigned /dev/scd0. I can burn CDs and DVDs, read from CDs and DVDs, boot from DVDs (and, I assume, CDs) but have been unable to use the lightscribe software to label a disk. I have lightscribe-1.18.11.1-0 and lightscribeApplications-1.18.6.1-0 installed, can run the GUI at /opt/lightscribe/Applications/SimpleLabeler/SimpleLabeler which promptly and stubbornly tells me "--<no lightscribe drives found>--". This IS a lightscribe drive, according to the specs, the box and the logo on the tray. This is on a fully update CentOS 5.4 system that has behaved very well since I built this box (Gigabyte MA770T-UD3P) about 3-4 months ago. This is certainly no a critical situation but having new stuff that doesn't work is rather irksome to me. Can anyone offer a clue or two? Thanks!

best parallel / cluster SSH
by Alan McKay 09 Feb '10

09 Feb '10

Hey folks, I stumbled upon this while looking for something else http://www.linux.com/archive/feature/151340 And it is something I could actually really make use of. But right on that site they list 3 different ones, and so I'm wondering what all is out there and what I should use. Is there one that is part of the standard CentOS? thanks, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"

xentop batch mode
by Nux 09 Feb '10

09 Feb '10

Hi guys, First of all, sorry to send this one here on the centos ml. I know it's kind of off-topic, but the xen-users list seems a dead end, I was hoping some of you guys are experienced in this. I have a problem with a xen 3.4.2 on Centos 5 x86_64 installation, I need to see the total/used/available memory of dom0 when using xentop, however in batch mode it doesn't seem to work. If I use the normal mode of xentop I get all that info nicely, however in batch mode it looks like this: http://bayimg.com/mAkNEAace A friend of mine told me that the memory info I need gets displayed on Centos 5 stock xen versions when running xentop in batch mode. Anyone can tell me what is going on? What am I missing? Is there any other way I can obtain that info? The xen is installed from gitco.de/repo/, should it matter. The kernel is 2.6.18-164. Thanks. -- Nux! www.nux.ro

Using (was: Announcing) Gluster Storage Platform
by Alan McKay 09 Feb '10

09 Feb '10

OK, you have my attention. But reading around on the website for 5 or 10 minutes and I'm still not sure what this is. What is it? Why would I use it? What would I use instead of it? (Who are its competitors) When would I not use it? I see this "The software is a powerful and flexible solution that simplifies the task of managing unstructured file data", but I have no idea what "unstructured file data" means. -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"

Sense: Logical block address out of range *Should i be worried sick about it or is it normal??* *There are 2 sas hdd connected into raid 1 to Adaptec AIC-9410W SAS controller. I can't get any information about my drives health (no S.M.A.R.T there) and to get information about raid quality i must restart system and enter raid bios- which is not very good option And maybe someone knows how to get health information om my raid\hdd from Centos ?

Asus Xonar DX PCIe sound card?
by tony＠softins.clara.co.uk 09 Feb '10

09 Feb '10

Can anyone here report success or failure at making the Asus Xonar DX PCI-express sound card work under CentOS 4? Or failing that, 5? Google only turned up people using it on Ubunt or SuSE... I need to specify the addition of audio outputs to a HP DL360 system, and don't want to buy stuff that will be a pain to get working. :-) Or can anyone recommend any other simple sound cards for PCI-express that have been trouble-free under CentOS 4 or 5?

auto mounting group shares
by Carlos Santana 09 Feb '10

09 Feb '10

I am using autofs to mount user's home and group directories. The setup works fine for home directories which are mounted after user logs in. The group shares are also mounted, but user has to manually do cd or ls command on group shares, e.g.: ls /groups/chemistry will mount chemistry group share. Is there any way to mount group shares automatically? I noticed that after successful login 'some program' performs chdir (cd) which probably tells autofs to mount home dirs. Which program does this operation? Is there any way to do this for group shares also? - CS.

slowness in sendmail - 60 second timeout
by Jerry Geis 08 Feb '10

08 Feb '10

I am sending an email from my machine devcentos5x64. the transcript below (hangs for 60 seconds) at the line: MAIL From:<root(a)devcentos5x64.msgnet.com> SIZE=56 AUTH=root(a)devcentos5x64.msgnet.com The email succeeds - but I am trying to figure out the 60 second delay. Neither email server is busy. Nothing is waiting. the DNS on both machines point to the same nameserver. The DNS responds very fast when looking up server names. What else can I look for to remove the slowness or delay? jerry ------------------------------------ date | mail -v -v -v -v geisj(a)pagestation.com geisj(a)pagestation.com...
