Hyperthreaded CPU and SMP kernel
by fredex 27 Oct '06

27 Oct '06

Hi gang! I'm using Centos 4.4 at work on a HP Proliant DL320 G2, which has a Hypterthreaded Pentium IV CPU. I used to use RHEL WS 2.1 on it, and RH installed and used the SMP kernel. Centos 4.4 did NOT install the SMP kernel. Is there some reason why I should NOT install it myself? I.e., some reason why an SMP kernel shouldn't be used on such a machine?

RE: [CentOS] Hauppauge WinTV-PVR-350 card on CentOS 4.X?

-----Original Message----- From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of Alfred von Campe Sent: Thursday, October 26, 2006 11:42 PM To: CentOS mailing list Subject: [CentOS] Hauppauge WinTV-PVR-350 card on CentOS 4.X? Anyone have the Hauppauge WinTV-PVR-350 card running on CentOS 4.X? What about MythTV? One of my users asked me today to upgrade the kernel on his CentOS 4.4 system today as he claims that this card will only work on recent kernels (2.6.16 or newer). I haven't found any documentation to support this (the Linux page on the Hauppauge web site is hopelessly out of date; it mentions the 2.2 kernel and Red Hat 6.2!). We are working on some video products, so this card is actually a business requirement. I know that upgrading the kernel on a CentOS system defeats the main goal of stability of an enterprise OS, so if that's the only way to get this card to work, I may have to move to Fedora Core 6.

In the early days of Linux, the great thing about Linux was that you COULD customize it to make do whatever you wanted. Then RHEL came along, and RH spread Fear, Uncertainty and Doubt about using Linux this way... If you need to make the card work, go ahead and customize the kernel. If you're a professional system admin, your job is to make things work. A few crashes here and there are better then employess who can't get the job done at all. If stability is the issue, using CentOS is much better than FC6 (or any other FC). FC is meant to be bleeding edge, and not stable. Thats my 3 cents.

AACRAID controller setup?
by Les Mikesell 27 Oct '06

27 Oct '06

This isn't exactly a Centos question but maybe someone here can help: Does the AACRAID controller (as in an IBM 3550) store its config info on the drives or internally? I only have one of the boxes and want to load Centos 3.x on several drives which can be swapped into servers at another location. With SCSI, all that took was a full disk dd copy and a little fiddling with the HWADDR for the nics. However these don't even see a disk until you run the raid setup in bios. Does anyone know if a new server will recognize the setup (one drive, no raid) from the cloned disk or what it will take to make it accept the swap? -- Les Mikesell lesmikesell(a)gmail.com

Experiences with CentOS & MacBook Pro?
by Benjamin Smith 27 Oct '06

27 Oct '06

Ok, I'm finally of a mindset to replace my now tired, aging Dell Inspiron 600m. I'm currently running Fedora Core on it, and am fairly happy with the software. Has anybody used CentOS on a Macbook Pro? What gotchas are there? (The first that comes to mind is the lack of a right mousebutton) Scouting on the Internet, I've seen that some people have trouble getting sound to work. I'm interested in the following: 1) Network/Wifi support 2) Sound 3) Video (don't need 3D, currently using 2D ATI Radeon drivers and am happy) 4) USB support (works?) 5) External video - I frequently have to give presentations!

seamonkey and new command mozilla-xremote-client
by Jerry Geis 27 Oct '06

27 Oct '06

All, For 4.4 mozilla is out and seamonkey is in. In the old mozilla there was no command mozilla-xremote-client. In the new seamonkey there is a command mozilla-xremote-client. Under mozilla you could do "mozilla -remote "openurl(www.cnn.com)" and it would set the current page to the url. Trying this under seamonkey does not work. however, I just found the new command mozilla-xremote-client that does work now for seamonkey. My question is the command is only /usr/lib64/mozilla-seamonkey-1.0.5/ this directory and /usr/lib64/mozilla* has mozilla mozilla-1.7.12 mozilla-seamonkey-1.0.3 mozilla-seamonkey-1.0.5 Is it an oversite that the mozilla-xremote-client is not in the "normal" bin places? After updates I can manually go out to machines and change sym links or anything how can a sym link automatically be updated to the new mozilla-xremote-client after a yum update? Thanks, Jerry

RE: [CentOS] spam control

Any time you have a "backup mx" server that does not do recipient validation for the domains it serves not only is it going to receive a lot of spam, it is going to be producing a lot. This is exactly the type of thing that lands IP addresses in blacklists in my experience. That being said you should be able to whitelist the IP of the blacklisted host before you do the rbl-checking. I know how to do this with postfix but not sendmail. I am not a sendmail user, but there are some sendmail users on the list who may be willing to help there. My guess is that if you post to the mailing list of the MTA in question you may raise their ire a bit as you seem to be trying to solve a problem further downstream than you should be (idiots on your network). I would fix your local problem (if you can). alex

ISA sound cards and stuff
by Aleksandar Milivojevic 27 Oct '06

27 Oct '06

I've created kernel-isa and kernel-isasmp packages (currently i586, there'll be i686 version soon too). Basically, it is centosplus kernel with ISA Plug and Play, ISA and PCMCIA sound cards and ISA network cards enabled. The change to kernel spec file to add these two packages was fairly simple, and I hope this might find the way into centosplus kernel. If maintainer(s) of centosplus kernel are interested, I can email the patch for the spec file and four additional kernel config files. I've tested it on my old laptop that has built-in ISA sound card (ESS ES1878). Kudzu and automatic sound card detection didn't work, however after I manually added entries to /etc/modprobe.conf, it all worked nicely. I had to manually specify io, irq, and dma settings in the options line, and I guess the same may be true for most ISA hardware. I don't really have anything Plug and Play to test, and no ISA network cards anymore. Anyhow, if anybody does have, it would be nice if (s)he could test if all works OK. The Plug and Play is in kernel, no userland tools should be needed (hopefully). The only sound card missing is Wavefront. The source code for device driver needs some updating (there seem to be a patch floating around somewhere though, haven't tested it yet). The way it is now, it produces unresolved symbols if compiled. I see these packages mostly useful for folks with older laptops (ISA based sound cards, buying cheap PCI card is no option on laptops). Also for folks with older motherboards that have run out of PCI slots, but still have a few free ISA slots. The packages are signed with my PGP key (same as the one used for this email, you can grab it from most PGP key servers). Key fingerprint is 46FE 7D24 2D50 566A FBF3 7395 4AE4 9AE0 D660 AA3F or something like that. The URL is http://www.milivojevic.org/linux/rpm/el4/i386/

I am trying to install x86_64 on a compaq r4000 laptop. booting the CD I have tried text mode only and graphicaly mode. I see the normal stuff flying by and I just get a black screen (in text for graphic install). I have tried linux acpi=off apci=off nousb nopcmcia linux noprobe all result in the same black screen.

Anyone seen this? any ideas? the machine is compaq r4000, turian 64 bit cpu. ATI video. windows on the same machine works fine. jerry
