Hi Rick,

The last kernel I patched was 2.6.28.8, but, I'm now in the process of 
rebuilding a couple of machines and place to install the ps-Performance 
Toolkit ISO directly (I'll post my How-To for that install in a few 
minutes too).

Here's what I did to patch 2.6.28.8...

FIRST - INSTALL CENTOS 5.3 on the machine...

NEXT ... follow these steps ...

1)	Download and untar the v2.5.23 Web100 patch from 
http://www.web100.org/download/ to your home directory with the commands ...
cd ~
wget 
http://www.web100.org/download/kernel/2.5.23/web100-2.5.23-200901150002.tar.gz
tar -xzvf web100-2.5.23-200901150002.tar.gz

2)	Download and untar the 2.6.28.8 kernel from http://www.kernel.org 
with the commands ...
cd ~
wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.28.8.tar.bz2
              tar -xjvf linux-2.6.28.8.tar.bz2

3)      Patch with the commands ...
cd linux-2.6.28.8
sed -e 's/EXTRAVERSION\ \=\ */EXTRAVERSION\ \=\ \.8/' < 
../web100/web100-2.6.28-2.5.23-200901150002.patch > web100.patch
patch -p1 < web100.patch

4)      Configure the kernel with the commands ...
cd ~/linux-2.6.28.8
cp /boot/config-`uname -r` .config
cp .config config.old
make oldconfig
*** Accept defaults for new options as you are asked for them, EXCEPT 
for the Web100 options. Set the Web100 options to be ...
IP: Web100 networking enhancements (WEB100) [N/y] (NEW) – Set to Y
                Web100: Extended TCP statistics (WEB100_STATS) [N/y/?] (NEW) 
– Set to Y
		Web100:   Default file permissions (WEB100_FPERMS) [384] (NEW) – 
Accept default
                Web100:   Default gid (WEB100_GID) [0] (NEW) – Accept default
                Web100:   Net100 extensions (WEB100_NET100) [N/y/?] (NEW) – 
Set to Y
		Web100: Netlink event notification service (WEB100_NETLINK) [N/y/?] 
(NEW) – Set to Y


5)      Finish configuring the kernel by running 'make menuconfig' then ...
Go to “Networking Support” --> “Networking Options” ---> “Network Packet 
Filtering Framework (Netfilter)” --->
Disable “Advanced Netfilter Configuration”
Go to “Core Netfilter Configuration”
Make all options “M”, except “Connection tracking security mark support” 
which should be disabled.
              Save the configuration.
6)      Build and Install the Web100 kernel with the following commands ...
make
make bzImage
make modules_install
make install

6)      Make the Web100 kernel the default boot by doing the following ...
vi /boot/grub/grub.conf
*** Change “default=1” to “default=0” ... this should be line #10 in the 
file.

7)	Reboot!!! Use 'uname -a' to make sure that the '2.6.18.8-web100' 
kernel has been loaded.

8)	Check that the web100 extensions are working with the command 'ls 
/proc/web100/'. You should see output similar to ...

0  10  12  14  16  18  2   21  23  4  6  8  header
1  11  13  15  17  19  20  22  3   5  7  9

	... At a minimum, you should see 'header', but, if not, reboot and try 
again. If you still don't, then repatch and rebuild your kernel.

	If you 'cat /proc/web100/header' you will see a long list of TCP stats 
dumped to the terminal.


Thanks,
Chris
