Nothing has changed there. >you might want to check the key is setup correctly on your machine : Many thanks. We got a corrupt version of the RPM due to a disk quota situation. All better now. Dave

Centos kernel c headers [dnk]
by Dustin Krysak 24 Jan '06

24 Jan '06

Good day -- I am having a go at installing VMware on my centos 4.2 machine. I am going through the configuration script and I am getting to the part where I need the c headers for my kernel. What package do I need to install to make these available, and where are they installed to? I have been searching for this with little luck. Thanks in advance. Dustin

upgrading 3.6->4
by Michael Thon 24 Jan '06

24 Jan '06

greetings - I'm trying to upgrade a centos 3.6 box to version 4. I tried to do an upgrade using yum but that failed and now the Cd installer is not letting me upgrade either. Here's what I did: following the howto, I tried to do the upgrade using yum. I installed the GPG key and upgraded the centos-release and the centos-yumconf packages. When I tried to upgrade yum package I ran into dependency problems. I downloaded and reinstalled the version 3.6 centos-release rpm. Then I downloaded and burned the CDs. I boot from the CD but I don't see an option to upgrade. I get to the installer screen that asks for the type of installation (desktop, server, workstation etc) but I see no option to perform an upgrade. Is the upgrade option hidden somewhere? did the installer not detect my centos 3.6 system? When I tried the yum upgrade, did I do something to make the installer think I have centos 4 installed (like the GPG key)? Any help is appreciated! cheers Mike

What cmd do I issue, to make the OS see the new card? Cheers. Mark Sargent.

HP NetServer LC2000r and LH6000r install woes
by Steve Huff 24 Jan '06

24 Jan '06

hello folks! i've got four HP NetServers, two LC2000r and two LH6000r. the CentOS 4.2 ServerCD can't see hard drives on any of them. each machine has a HP NetRAID controller; the LC2000rs have a NetRAID-1Si and the LH6000rs have an Integrated NetRAID. each controller has three 9GB drives, two mirrored and one hotspare. each machine boots ok (the LC2000rs need "linux noacpi" or they complain about being in a weird power management state and panic), each loads the megaraid driver, but none of them can see any volumes. fixes i have already tried: 1) on the LH6000rs i have disabled "Smart IRQ" reallocation; on the LC2000rs i have disabled "Reserve PCI Bus Numbers" as described in this document: http://tldp.org/HOWTO/HP-HOWTO/hp-hardware.html#AEN792 these fixes have made the megaraid driver stop complaining about IRQ conflicts or routing errors. 2) i have tried switching each NetRAID controller from I20 to "Mass Storage" mode; no change. 3) i have tried manually adding the i2o_block driver; no change. has anyone encountered similar problems with this hardware? better yet, has anyone resolved them? any other ideas? do i need to do anything to the logical volumes on the NetRAIDs other than create and initialize them? i'm currently downloading the full CentOS install media, in case this is some sort of deficiency in the ServerCD. thanks, steve --- If this were played upon a stage now, I could condemn it as an improbable fiction. - Fabian, Twelfth Night, III,v

Ext3 filesystem access after downgrade from v4.2 to v3.6
by Plant, Dean 24 Jan '06

24 Jan '06

I need to downgrade a system from Centos x4.2 to v3.6 (x86) due to performance problems with Arkeia Network Backup and AIT-4 tape drives. The backup database is stored on a v4.2 created ext3 partition. When accessing this partition after the downgrade, Centos complains on boot that fsck.ext3: Filesystem has unsupported feature(s) (/dev/sda5) *fsck: Get a newer version of e2fsck! [fail] If I comment the partition out of /etc/fstab the machine boots as normal and I can manually mount the filesystem. My questions are: If I use the v4.2 ext3 filesystem on v3.6 I am likely to corrupt the data? And what is the best way fix this problem? Do as it says and try and upgrade e2fsck or is there a better fix? Thanks Dean.

Self-signed certificates
by Thomas E Dukes 24 Jan '06

24 Jan '06

Hello, I am trying to create a self-signed certificate for a sub-domain. Creating the certificate is not the problem. I used cacert.org to complete it. When I made the certificate, it was for the sub-domain but the certificate for the top-level domain is the certificate that appears. In the <VirtualHost> section for the sub-domain, I have pointed to the sub-domain key: SSLCertificateKeyFile /etc/httpd/conf/ssl.key/subdomain.key. This is how I made the key: openssl req -nodes -keyout private.key -out subdomain.key Any help would be greatly appreciated.

Arguments to continue using it
by Alain Reguera 24 Jan '06

24 Jan '06

Hello, This afternoon I received the new that my institution, in the main direction, is planning (for political reasons, I don't know which one??) migrate to Debian. I have a hotted conversation with my boss cause I've been working on CentOS during near a year and half. I explained it that both distros just implement the protocols that are standards, that could be installed a web server in a Debian Box or in a CentOS Box, both can use apache and generally the service will be stable in both, without a lot of differences. Also that the use of each one is indifferent, just a matter of user's comfort and that means, it will take a long time to change to other, because not only will be the time in planning services, but the time in learn a new way of do it too. Note: if I said something wrong correct me please. The arguments they gave to me were, what happen if redhat close the base packages, they don't have to release them, but just to the buyer, and we can't buy the distro, there are others distros like debian that is totally free, and without dependencies of proprietary industry. I really struggle a little more to defend, CentOS and my comfort on it ;) , but have not solids arguments about that issue, I really never worried about it. Would some of you explain me this issue, or point me somewhere to read?. I'll really appreciate that.

log server

Any recommendations for log servers? Mostly for firewall activity but I'd like to use one for squid also if one is available.
