    Latest kernel build for cento 3 system - 2.4.21-32.0.1.EL?

    Hi all,

    I wonder is kernel 2.4.21-32.0.1.EL , the latest build for cento 3 server?

    doing yum did not give any upgrade for kernel..

    While on other redhat server, version .37 EL is available for them.

    Lastest CentOS is centos.3.4.3 and the lastest Kernel version is 2.4.21-37.EL.

    At least this is what I get on my last yum update.

    Sorry, I did a check after seeing your version is 3.5 my version is also 3.5:

    cat /etc/redhat-release
    CentOS release 3.5 (Final)

    Did another check on the kernel version, it is confirm to be 2.4.21-37.EL

    uname -r -v
    2.4.21-37.EL #1 Wed Sep 28 14:14:23 EDT 2005

    Decided to have a check on centos mirror's site and this is what I found:

    The latest kernerl for http://mirror.centos.org/centos/3.5/os/SRPMS/ is kernel-2.4.21-32.EL.src.rpm



    The latest kernerl for
    http://mirror.centos.org/centos/3.5/updates/SRPMS/ is kernel-2.4.21-37.EL.src.rpm


    So, it seem that it is in the update but not the os based directory and I believe you don't have the update tree in your yum.conf, so put the following in your yum.conf file:

    [update]
    name=CentOS-$releasever - Updates
    baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
    gpgcheck=1


    And you will get 2.4.21-37.EL.

    If not, post your yum.conf and let us take a look.

    Thanks.

    from /etc/centos-yum.conf, i had the exact same copy. what command did you issue to upgrade kernel using yum?

    #released updates
    [update]
    name=CentOS-$releasever - Updates
    baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
    gpgcheck=1

    I usually do yum check-update first and yum update manually so that I can choose which package to upgrade and make sure the update packages are compatible with some of my customisation script.

    You sure your default configuration for yum is /etc/centos-yum.conf but not /etc/yum.conf ?

    rpm -qa | grep kernel

    the server return:
    [~]# rpm -qa | grep kernel
    kernel-2.4.21-27.0.1.EL
    kernel-2.4.21-32.0.1.EL
    kernel-utils-2.4-8.37.12

    look like the server wasn't install with the latest kernel build and yet yum did not give me any option to upgrade.
