Also, the use of spamcop should (in my opinion) be suggested with a caveat that the user read up on their own description of their criteria for blocking mail. I have seen large email providers and even ISPs etc blocked by this list, even if temporarily. Just my 2 cents, Alex

I've launched several I/O operations on usb disks to see if i can reproduce the bug, not "succeeded" by the moment but let me check it for several days.

detecting ECC errors?
by Christian Nygaard 25 Oct '06

25 Oct '06

How do you detect ECC memory errors when CentOS is booted? Just had a strange hardware error where a server machine hang during anaconda install it passed memtest86 test but the bios dmi log showed dimm bank 1b had failures. Now I wonder what would happen if a machine running in production would get such problems, how do you detect it without having to go into bios? Hints on what to use? Chris

Gnome's profiles tool?
by Jordi Espasa Clofent 25 Oct '06

25 Oct '06

Hi all, I'm looking for a tool to create and manage the users' profiles in GNOME desktop environment. I've searched Pessulus (included in GNOME admin tools by default according GNOME docs) whitout success. I've tried to compile Sabayon (the CentOS rpm is not avaiable I think) but there are a lot of dependencies to resolve. ¿Any ideas? Thanks in advance. -- Jordi Espasa Clofent PGP id 0xC5ABA76A #http://pgp.mit.edu/ FSF Associate Member id 4281 #http://www.fsf.org/

Help request...recovering LVM on centos 4.2
by Sanjay Arora 24 Oct '06

24 Oct '06

I installed a Centos 4.x system using a lvm install across four HDDs. It is my first install using LVM. System had a power-failure and stopped booting up. A new trainee simply took out the HDDs and restarted the file-server on a fresh HDDs. Now the problemis that the four HDDs have data. But the order of the HDDs (of install....1st primary, 2nd primary etc.) is unknown. Earlier we used to boot with knoppix live cd and recover data through rsync. Knoppix is not automatically recognizing lvm partitions. My query is to ask for step by step instructions on finding & mounting my lvm partitions correctly using knoppix or installing earlier hdds one by one in the new file-server & restoring data to users. Pointers on any howtos or detailed examples of recovery would also be appreciated. With best regards. Sanjay.

DMA disabled on SATA disk with Core Duo/i955 machine (Inspiron 6400)
by first last 24 Oct '06

24 Oct '06

I am trying to use CentOS 4 on this machine and it does not allow me to set DMA to 1, it just says that it is not possible. I have tried updating to the latest release and it still won't work. I have searched for it on Google and there is a thread mentioning the same machine and CentOS, but none of the solutions (-p, -X 12) seem to work at all and there is no "it works!!!!!" message. Is there anyway I can get DMA working or will I have to wait for CentOS 5? Will any of the "unsupported" kernels work? (I would try Ubuntu's kernel on CentOS, as I am successfuly using that distribution, but it is a bit stupid not to use SELinux and it probably wouldn't work either).

RE: [CentOS] RHWAS rebuild efforts
by Bisbal, Prentice 24 Oct '06

You don't need a Red Hat subscription to get any SRPMs from RHEL. The GPL requires that they provide them for free. I believe that applies even th RHWAS, since that's still based on GPL'ed Linux code. You can get RHEL RPMs here ftp://ftp.redhat.com/pub/redhat/linux/enterprise/4/en/os/i386/SRPMS/ -- Prentice -----Original Message----- From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of Greg Swallow - SkyNet Sent: Tuesday, October 24, 2006 1:36 PM To: 'CentOS mailing list' Subject: RE: [CentOS] RHWAS rebuild efforts jim bartus wrote: > Nothin?

Jim, I don't know if this discussion has been taken off-list, but why don't you just get this service (more specifically the Application Stack) from Redhat? As I understand it, all CentOS wants is someone with a RedHat subscription to provide to them the SRPMS which have a distributable license. The RedHat subscription for the application stack looks to be $1999 for one year - https://www.redhat.com/apps/commerce/cart.html?store_cart:add_item_cb=SVC023 9 Greg _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos The contents of this communication, including any attachments, may be confidential, privileged or otherwise protected from disclosure.

RE: [CentOS] CentOS 3.8 Kernel Update with NVIDIA Video Card

Download the latest driver packager from NVIDIA (e.g., NVIDIA- Linux-x86-1.0-8774-pkg1.run) 2. Boot the new kernel to run level 3 (or wait for it to fail to go to run level 5) 3. Log in as root and run ./NVIDIA-Linux-x86-1.0-8774-pkg1.run and answer the prompts Oh yeah, you will most likely need to have the kernel-devel RPM installed so that it can rebuild the kernel module for CentOS. Alfred _______________________________________________ You don't need to reinstall the lated NVIDIA driver every time you update your kernel. In fact, this will cause problems if you need to revert back to your old kernel. You just need to install a new kernel module compiled for that version of your kernel. If you install the entire driver package, you will be installing new versions of all the related libraries, too. Then if you revert to the earlier kernel, that kernel module be an earlier version that doesn't match the version of the newer libraries, and you'll have a similar problem. Then to fix this one, you'll have to install the earlier kernel sources to recompile the kernel module for that kernel... And so on, and so on... If you know you'll never revert to the earlier kernel, it's okay to just install the whole new driver package. If you might revert, it's better to learn how to install just the kernel module. I forget the exact syntax, but if you do 'man nvidia-installer', all the details are there. Even better, HP supplies the nvidia drivers as RPMS. These RPMS are for RHEL, and include a script /etc/init.d/nvconfig. At startup, this script checks to make sure that the current kernel has an nvidia module. If it doesn't find one, it installs just the kernel module, no fuss no muss. The HP RPMS are just the nvidia drivers repackaged into RPM form. I recommend either using those RPMs, or at least extracting the /etc/init.d/nvconfig script from the RPM and be done with it. That's what I did.
