    Post updating my kernel

    Hi i have a dedicated server with centOs 4.x OS with whm and cpanel i recently notice a message saying that kernel needed updating,

    I know there's a command i can run to update the kernel (the easy way) does anybody know which command is?

    thanks a lot.

    uname -a // for more info.

    yum update kernel // doesn't update you to the 'latest' kernel but what centos has out.

    The kernel is the heart of the system, so i would contract some one to build one for you.

    But as Jeremy mentioned it will not update you to the latest kernel. The latest kernel as of today is 2.6.19, but you can see your yum is updating it to 2.9 only.
    It is always suggested to upgrade to the latest stable version, which needs to be done from source.

    The centOS kernel will be fine as this is the latest stable stock kernel by your vendor. These will include any back ports they feel are necessary.

    As you appear to be unable to compile a kernel from source I would advise you stick with your stock kernel.
