From WHM "You are running an insecure kernel (2.4.18-14). You should upgrade to a newer version as soon as possible to avoid your system being compromised."

Can anyone help me upgrade kernel.

I got the same problem
I tried it with up2date but the redhat network is flat.

Anyone have a sollution???????

To update kernel,
/usr/sbin/up2date --nox -f kernel

Must have your own account at rhn.
To get that type rhn_register
Follow the steps.

After everythings all done, reboot.

root@..... [/]# /usr/sbin/up2date --nox -f kernel

What do i do now

ignore it. RS uses lilo, not grub.. its a common error iv noticed..

just check to make sure lilo.conf was updated with the new kernel

pico -w /etc/lilo.conf

then after you save that

lilo -v -v

check for any error... if its clean, then

shutdown -r now

to reboot.

I dont think it is?

Just make the changes above in red and you should be good to go. Make sure you run lilo -v -v before rebooting. Any errors should be resolved before rebooting.

Whats wrong

To register, run "rhn_register".
root@server [~]# rhn_register

what's wrong

your not using that kernel..

replace the line in lilo.conf with this

image=/boot/vmlinuz-2.4.20-18.8
label=linux
initrd=/boot/initrd-2.4.20-18.8.img
read-only
append="root=LABEL=/"

doh! guess that would help lol!

Missed that you were running 8.0

root@global [~]# /usr/sbin/up2date --nox -f kernel

This is what I got. & lilo.conf is;

I think I got it... everything was well and kernal has been updated.

Thanks!

Thank you, this was very helpfull! But, the most recent stable kernel is 2.4.21, why up2date install 2.4.20-18.7?

kernel-2.4.20-18.7 is the latest kernel released from Redhat as a package for Versions < 8.0.

This is what I did in Shell. Now have not a clue what to do next. I have Red Hat 8.

When I goto my Server I get this message: You are running an insecure kernel (2.4.18-14). You should upgrade to a newer version as soon as possible to avoid your system being compromised.

I went to shell and typed this in:
root@server1 [~]# /usr/sbin/up2date --nox -f kernel

This is what was listed next

1. forceInstall Yes
2. isatty Yes

Enter number of item to edit :


So what option do I choose next. I just want to make sure I have the latest Kernel.

Many thanks for any help I can get

choose option 26 remove kernel from the list then try again..


up2date kernel works just as well and automagickally updates lilo

Thanks Matt!!!

I did what you said and then I had to register at RedHat and then found out I had to setup some more info on what needed to be updated at rhn.redhat.com and then did a reboot now I am getting this message on the server:

"Unable to fetch Web Host Manager news. The News server may be down or unreachable. "

So trying to see what I need to do to fix that.

Again thanks for your time
