    Default Insecure Kernel

    You are running an insecure kernel (2.4.20-20.9). You should upgrade to a newer version as soon as possible to avoid your system being compromised.
    I like that message, but any info on how and where i can get upgrades? It would be nice, especially since my administrator that normall does this is out of town on vacation, and i have no clue how to do this.

    I know my way around FreeBSD better

    Hello

    You have to have root shell access, then, run:

    up2date

    you might have to register with redhat, but it is free

    .... on the other hand if you don't know much about linux and rpm, and up2date... is best to wait for your administrator.. it might be safer

    because the kernel is the main sistem program, you may criple the server...

    Has the server been rebooted since the kernel upgrade?
    What does your grub.conf file say?

    You really shouldn't be fooling around w/ a kernel if you have no idea what you are doing.

    First:
    rpm -qa | grep kernel

    What does the above give you?

    If the new kernel is listed then check /etc/lilo.conf ( if grub is empty you probably use lilo ). Make sure the new kernel is listed in there, if its not add it ( CAREFULLY ). If it is listed, make sure its listed as default. Run lilo -v -v and check for errors. Make sure there is a * beside the new kernel and reboot and cross your fingers.

    If you are uncomfortable with this, HIRE SOMEONE THAT KNOWS WHAT THEY ARE DOING!!!

    Assuming you are running redhat 7.3:

    wget http://updates.cpanel.net/linux/redhat/updates/7.3/en/os/i686/kernel-2.4.20-28.7.i686.rpm

    rpm -ivh kernel-2.4.20-28.7.i686.rpm

    When thats done, check your lilo.conf or grub.conf make sure everything is in check and the new kernel is selected. Also make sure the old kernel remains listed just in case! Then reboot and cross your fingers. If it doesn't come up after a reboot ( issue "shutdown -rf now" to skip fsck ), say 5 minutes max call up the DC and have them boot to the older kernel ( make sure you know what the older kernel is ).
