Yum update to specific kernel version

kernelrhel5yum

On rhel 5.3 I want to update to kernel version "2.6.18-128.8.1.el5" due to a security patch.
When performing:

yum check-update | grep kernel
kernel.x86_64                            2.6.18-164.2.1.el5     rhel-x86_64-server-5
kernel-devel.x86_64                      2.6.18-164.2.1.el5     rhel-x86_64-server-5
kernel-headers.x86_64                    2.6.18-164.2.1.el5     rhel-x86_64-server-5

But 2.6.18-164.2.1.el5 correspond to rhel 5.4, and I dont want to move to this version, I want to keep rhel 5.3.

I tried

yum update kernel-2.6.18-128.8.1

But it seems to be the wrong way.
How could I update the server to this specific kernel version?

You are on the right track. You just didn't specify the kernel version the way yum expects it. The correct command would be

yum install kernel-2.6.18-128.8.1.el5

(Note that kernel packages are not updates for each other, each of them is a separate install, and the old ones remain until you run "rpm -e".)

I had this problem with my provider in evenings. It looks like some router in the chain between you and target host doesn't proper work with tcp_sack. The solution is to disable it in /etc/sysctl.conf

net.ipv4.tcp_sack = 0

But this is very bad for server, because it will slow down tcp connections. You should make abuse to your provider

Yum search – package version

You can find the version number of a package in your repositories with the yum info command.
