Thunderbird: can't seem to install french spell checker
by Niki Kovacs 14 Mar '08

14 Mar '08

Hi, I can't install a french spell checker in Thunderbird. There's a link in Thunderbird's preferences, to download new dictionaries, but it's dumb. So I downloaded the dictionary manually (spell-FR.xpi) and installed it in Thunderbird using the 'Extensions' dialog. But the installed dictionary doesn't appear anywhere. Googled some over this problem, and it seems like this happens to quite some people. Anyone on this list successfully installed a non-english spell checker in Thunderbird? Cheers, Niki

Recommendations for a “real RAID" 1 card on Centos box
by Therese Trudeau 14 Mar '08

14 Mar '08

Hi, I'm considering setting up my Centos Desktop machine for RAID 1. I read a lot of good info at this site:http://linuxmafia.com/faq/Hardware/sata.html#intel-vitesse about differences in fakeraid and real raid cards. The hardware I plan on installing this RAID card into is an Intel DP35DP motherboard with the Intel E4500 dual core processor, and I have two Mator 500 gig SATA hard drives. Can anyone recommend a good “real raid” card for my Linux? What I am looking for is to plug in a RAID controller card out of the box, and without having to load any drivers onto my Centos 5.1 box, have the Real hardware RAID card automatically do all the work, mirror my hard drive onto the second backup drive and do all the work for me. Do such cards exist? If so which model /manufacturers do you recommend? Any experiences/info/insights on hardware RAID cards good or bad on centos boxes would be appreciated. _________________________________________________________________ Climb to the top of the charts!

Therese, You are definitely making your life more difficult then is needed for a desktop machine. You said you have 4 hard disks. Make a software RAID1 out of the first two. Make a software RAID1 out of the second two and your good to go. You can use dump/restore to backup the logical volumes on the second RAID set to an LV on the first. No need for bare metal restore. Just need to get some working Linux distro to be able to read your files. Going HW RAID for your desktop is going to get in the way of you getting things going and if your HW RAID card fails then what? Your drives will only work with another identical HW RAID card. -Ross ----- Original Message ----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: CentOS mailing list <centos(a)centos.org> Sent: Fri Mar 14 09:08:39 2008 Subject: RE: [CentOS] Recommendations for a “real RAID" 1 card on Centos box >>> You can turn on write back caching if you have a UPS as well >>> (provided your UPS is wired into your system for a graceful shutdown) >>> >> >> Hopefully you have a redundant PS unit.

I've seen more > UPS failures than I've ever had failed PSUs on proper server grade hardware. This might be getting a bit elaborate for a desktop machine. I really want RAID because I'm tired every couple years of hard drive crashes and having to start from scratch and spending a week setting up new drives and getting my design software back on line and trying to recover data. What do you think of alternative back up systems, such as a tape backup with bare metal restore software? I'd go that route instead if I could fine a solution which would allow me to restore to different hardware, i.e. if my motherboard dies and I need to buy a different brand or model MB. I know Storix back up software has this capability - I use storix on my Linux server with RAID 1. @ home I have one Linux and one Windows desktop machine. _________________________________________________________________ Connect and share in new ways with Windows Live. http://www.windowslive.com/share.html?ocid=TXT_TAGHM_Wave2_sharelife_012008… CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.

This is getting OT and you are going to end up spending more on redundancy then if you just called Dell and ordered another computer. ----- Original Message ----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: CentOS mailing list <centos(a)centos.org> Sent: Fri Mar 14 09:31:00 2008 Subject: RE: [CentOS] Recommendations for a “real RAID" 1 card on Centos box > That is true, buy high quality stuff up front for fewer problems down > the road.

So for a top quality power supply for a mission critical desktop machine, which brand(s) would you reccomend?

As an alternative to RAID1 for a mission critical desktop machine @ home, what would you reccomend? Maybe a bare metal restore solution able to restore to different hardware, (i.e. if a motherboard dies and drive crashes due to power spike or some catastrophe, I'm screwed if I can't find the exact same make - model)? _________________________________________________________________ Connect and share in new ways with Windows Live. http://www.windowslive.com/share.html?ocid=TXT_TAGHM_Wave2_sharelife_012008… CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.

CentOS 5.1 install via PXE Failure
by James Gray 14 Mar '08

14 Mar '08

Hi All, This has to be something simple....but it's really busting my chops. We have a PXE boot server that is used for initial installation of a number of operating systems and it works well. However the CentOS 5.1 x86_64 install is seriously broken. We've made the PXE boot images available from "centos/5/os/x86_64/images/pxeboot/" in the tftp boot etc. We've rsynced our mirror with a local Tier 1 mirror (rsync://ftp.monash.edu.au::ftp/linux/CentOS/) Next we fire off the installation using the following in /tftpboot/pxelinux.cfg/default: label 4 kernel centos5/x86_64/vmlinuz append initrd=centos5/x86_64/initrd.img ramdisk_size=7000 ks=http://<insternal_install_server>/CentOS-5/dot/kickstart/ks.cfg.x86_64 ksdevice=eth0 language=en text The installer starts, loads the kickstart script (attached), successfully verifies the installation media, checks the dependencies for the packages to be installed, formats the hard drive(s), then attempts to download the package: sysklogd-1.4.1-39.2.x86_64.rpm At this point the installation will not continue because that package is not part of the installation! I've verified our internal mirror with 3 other Tier 1 rsync hosts and all agree, our images are up-to-date and the CORRECT sysklogd package is actually: sysklogd-1.4.1-40.el5.x86_64.rpm (Note the build is 40.el5, NOT 39.2). I've tried creating a symbolic link from sysklogd-1.4.1-40.el5.x86_64.rpm -> sysklogd-1.4.1-39.2.x86_64.rpm, and sourcing a real package for sysklogd-1.4.1-39.2.x86_64.rpm. These last two attempts have still resulted in the installer claiming the RPM is corrupt, not available etc. This is killing us :( The odd thing is the James -- There will be big changes for you but you will be happy.

FOSDEM Presentations
by Filipe Brandenburger 14 Mar '08

14 Mar '08

Hi! I was looking at the pictures and devroom of FOSDEM 2008 in www.centos.org. I was really interested in the presentations related to CentOS. Would you mind making them available somewhere on the site? I think that would be great documentation for some of the topics. In particular, I wonder what are Karanbir's opinions on "Hosting custom applications on CentOS 5", I guess I already know what many of the items will be (package everything in RPMs and manage them with yum), but I'm really curious about the other tips he would have to give. Thanks a lot! Filipe
