For few days I try to configure a cluster with piranha.

I have some problems.

Here is few information about my software configuration :
I use RedHat 6.2
I use Piranha-0.4.14-1

About Kernel I use the original kernel that was in the RedHat 6.2 CD.

question 1 :
I read in some documentation that to install and configure Piranha, we have to 
have Redhat 6.1 or Redhat 6.2.
About that in the documentation they speak about lvs patch.

Do I need to apply this patch to my original kernel (redhat 6.2) ?
And if yes how I do that ? 

How can I see if a patch had been applyed to a file ?

At the level of my network configuration :

I use one router, one real server and one computer to simulate a client 
(someone who wants to see a site html install on the real server )

My configuration installation :

|                          |
|eth0=        |eth0=
|eth0:1= (vs1) | ---------|
|----------                |          |
| active   |               | computer |
| router   |               | Internet |
|          |               ------------ 
|eth1:1= (NAT router)
|    rs1  |             

At the level of my configuration (files) :
In /etc/sysctl.conf I activate Defrag and Ip_forward.
#Disables packet forwarding> 
net.ipv4.ip_forward = 1
# Enables source route verification> 
net.ipv4.conf.all.rp_filter = 0
# Disables automatic defragmentation (needed for masquerading, LVS)
net.ipv4.ip_always_defrag = 1
# Disables the magic-sysrq key
kernel.sysrq = 0

I have verify that these options are activated when the computer start .

cat ip_forward (the result is : 1)
cat ip_always_defrag (the result is : 2)

In /etc/rc.d/rc.local I add this line :

ipchains -A forward -J MASQ -d
I have veify that option is activated when the computer start.

ipchains -L

At the level of my real server I add the default gateway :
the real server is a window OS.
the gateway i configure is

I do a test to see if it works.
-> ping
-> ping 

It's ok

The passwd section for piranha is correct :> http://xxxxx/piranha
- it ask me for a password , I type it, it is ok ( i type it before with the 
command piranha-passwd *****)

- after i put the information concerning my cluster with the web interface,
- all is ok . I can verify by editing the file /etc/

- after I start the cluster, I type pulse
the daemon pulse run after few second, 1 daemon nanny run and lvs daemon run as 

- When I look at the web interface on the control monitoring
I can read at the level of current LVS routing table :
- My Primary server IP : with the correct port 80

- The adress IP of my real server 

When I try to connect to my cluster puting 
on the computer internet (IP :
- It doesn't work (after 5 or 6 minutes there is an indication :
- "there is no response the server may be out of order"

- I did several test to understand the problem, my observation are :
- at the level of the web interface i can see that there is a 
connexion when i try to reach one of the two real servers with the computer 

- at the level of real servers (windows) I can see that there 
is a connexion with the active router (with the log files).

Is there someone who can help me ?

Thanks in advance,

Stephane (excuse me for my bad english i'm french)
