    Okay..

    After spending about 3 hrs in the datacenter, (I've also installed 2 new HDD's), and doing a lot of tweaking from home (SSH) I just discovered that the OS is not seening both CPU's :-(

    Code:
    host:~# cat /proc/cpuinfo
    processor       : 0
    vendor_id       : GenuineIntel
    cpu family      : 15
    model           : 4
    model name      : Intel(R) Xeon(TM) CPU 2.80GHz
    stepping        : 3
    cpu MHz         : 2800.240
    cache size      : 16 KB

    bogomips        : 5583.66
    
    With the old OS on it (Fedora RC4) it was like this:

    Code:
     cat /proc/cpuinfo

    Is it hard to get the Debian install to see both CPU's, adn can I do this through a SSH connection?

    uname -a is giving me
    Linux host.removed4.now 2.4.27-2-386 #1 Wed Aug 17 09:33:35 UTC 2005 i686 GNU/Linux

    kernel update for Dual Xeon with HT

    I think you have to do this:

    Give this command to find the available SMP (multiprocessor kernels):

    apt-cache search kernel-image | grep smp

    Choose this linux kernel for use with dual xeon:

    kernel-image-2.6.8-12-em64t-p4-smp

    Linux kernel install with this command:

    apt-get install kernel-image-2.6.8-12-em64t-p4-smp

    This commands reads the installed linux kernel:
    uname -a

    Remove the not necessary current kernel:

    dpkg --purge --force-remove-essential kernel-image-2.6.8-2-386
    (or other current kernel according the result of command uname -a)

    Reboot your system.

    This will give you full support for your dual xeon system with hyperthreading as well.

    Thanks Hans,

    Only problem is that a friend helped me with it.. He installed the kernel-image-2.4.27-3-686-smp

    I just asked him why he did not use the kernel-image-2.6.8-3-686-smp version..

    He told me that he did not have any experience with upgrades from 2.4.x to 2.6.x (your info did help him)

    Not sure if it's any different, and if it's worth risking upgrading the kernel again to 2.6.8

    Thanks again for your help!

    to consider ...

    2.4 or 2.6 kernel...The most important is that you have full advantage of your Debian SMP system now.

    I also do not have the experience with updating from 2.4 to 2.6.
    At this point i can not help you.

    But if you just started you with a new and empty system you can consider to start over again and install the 2.6 kernel.

    You can do this with the "linux26" command after inserting the Debian CD in your drive.

    Maybe not important for you but good to know is that the 2.4 kernel series do not support SATA drives.

    I have also seen that you choose for a 32 bit version.
    I have installed the unofficial Debian Sarge 64 bit version with the kernel-image-2.6.8-12-em64t-p4-smp.

    This Dual Xeon system is up and running for months now without any problems. Very stable. So if you want to give it a try....
    (I mentioned this for consideration and have a little bit more advantage of your dual XEONs)

    I see. I might go back to the data center tomorrow, and try a new clean in stall with the linux26 option.

    If your system has a Debian rescue system, you don't need to go to the data center, you can install a new Debian right through SSH. And of course, you need to install an SMP kernel.

    Here's a nice tutorial, unfortunately it's in German, but maybe you understand the commands:

    Thanks again falko,

    I can read German (me Dutch), but I could not even do this if it was in Dutch :eek:

    How much do you charge per/hr, or session? (I need more things that need looking at by a pro.)
