Hi Joe
Thanks a lot for your reply.
I have made the changes as you have suggested.
But still
"when i send a http request to the virtual IP from client, I receive no
response."
Network looks like the following (I am testing with one real server at the
moment)
[CIP]192.168.3.38 --> [eth0:162 VIP]192.168.3.162 --> [eth0
RIP]192.168.2.197
[eth0 DIP]192.168.2.160
Director:
OS is Trustix Secure Linux - kernel 2.4.34-2tr
Ipvsadm version: 1.0.12
1 NIC
DIP Eth0 192.168.2.160
VIP Eth0:162 192.168.3.162
Real server:
OS is Fedora core 2 - kernel 2.6.5-1.358
1 NIC
Eth0 192.168.2.197
Iam following the steps in LVS mini howto to setup LVS nat.
5.2 setup by hand
Step 1: i have modified mini-rc.lvs_dr-director
script according to my config and run the script on the director.
root@director ~# sh /root/ajay/lvs-nat-dir-setup.sh

=> `index.html.1'
Connecting to 192.168.3.162:80 <http://192.168.3.162/>...
Behaviour:
When i attempt to http to the virtual IP from client, I receive no
response, ipvsadm shows one inactive connection.
RIP can ping DIP, VIP and CIP
step 4
root@director ~# ipvsadm -L -n
IP Virtual Server version 1.0.12 (size=4096)

0 1
NOTE:
i have a firewall running on the director
and i have cleared the iptables using iptables -F
Do let me know if you need more information to answer the query.
Any thoughts would be very much appreciated!!
Thanks in advance,
Ajay
