HI All,

I have a New 64bit fedora 10 remote dedicated box from Hosting Company. I have updated its kernel from 2.6.27.21-170.2.56.fc10.x86_64 to 2.6.27.24-170.2.68.fc10.x86_64.

After rebooting Server its always boot from kernel-2.6.27.21-170.2.56.fc10.x86_64. It totally ignore the sequence of kernel booting defined in grub.conf. i have commented all older kernel entries in grub.conf except New one-2.6.27.24-170.2.68.fc10.x86_64. Even then it boot from older kernel 2.6.27.21-170.2.56.fc10.x86_64.

For information i have not installed lilo. Can anyone tell why and how server is booting from a specific kernel and not entertaining grub.conf.

I have checked the booting logs, server simply boot from kernel-2.6.27.21-170.2.56.fc10.x86_64 and not errors in logs. can someone tell me whats going on with my box.

Regards, mateen

Dear All,
I've generated rootfs using buildroot and copied (rsync -av /opt/* /media/CF) on compact flash
copied kernel vmlinuz image to /boot and edited menu.lst and
then I have install grub using grub-install successfully
But now I'm getting following error.
Error 13: Invalid or unsupported executable format.

Can anyone help me

Check /boot

Make sure the kernel(s) you think you're booting exists in /boot.

It also might help to post your grub.conf in the forum.

Thanks Mitch Frazier:-

I have removed the /boot partition separately added for booting. MBR had
the boot entry on /, instead of /boot, which was causing the problem.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6

Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.
