I have some dedicated server and today trying to upgrade the kernel of all of my servers,
One of our server have Fedora 6 and another Fedora 7 and another server have CentOS .
when I going to kernel.org I saw the 220.127.116.11 as latest kernel version, is it true?
when I run "yum upgrade" my kernel upgraded to 2.6.18-53 (for Fedora 6 and CentOS) and when I run run yum upgrade on Fedora 7 show this message: updates 100% |=========================| 2.3 kB 00:00
fedora 100% |=========================| 2.1 kB 00:00
Excluding Packages in global exclude list
Setting up Upgrade Process
No Packages marked for Update
and when I run uname -r on this server the kernel version is 18.104.22.168-80.fc7 .
As andren said, different Linux Distributions use different kernel trees, and can go by totally different names and versions as they are compiled differently.
Pretty sure 2.6.18-53 is the default kernel with a Centos 5.0 install. You should consider updating the system to CentOS 5.1. A simple "yum -y update" will take care of everything. If I remember correctly 2.6.18-53.1.19 is the latest CentOS Kernel which came out a few days ago.
