basical question

Hello,

I just started to try LVS recently.

I can't start service of ipvsadm.
The diagram is below:
=======================================<
ClientPC(192.168.1.103)
|
|---LVS Server(eth0:192.168.1.94, eth0:0:192.168.1.70)
|
Web Server(192.168.1.90)
=======================================>

I did "service ipvsadm start" but 80 port on LVS Server isn't opened.

The operation on LVS Server is below:
=======================================<
[root at fedora3 ~]# ipvsadm -A -t 192.168.1.70:http -s rr

[root at fedora3 ~]# ipvsadm -a -t 192.168.1.70:http -r 192.168.1.90:http -m -w

=======================================>

And the log "/var/log/messages" on LVS Server is below:

And the operation of telnet from LVS server to localhost 80 is below:
=======================================<

And the condition of ifconfig and route is below:

=======================================>

And there's no process named "ipvs" or like that when I check by "ps aux".

And my OS is fedora core 3.
And the version of ipvs is "ipvsadm v1.24 2003/06/07 (compiled with popt and 
IPVS v1.2.0)".

Generally speaking, some port is opened when ipvsadm service starts?
Or is it normal that any port is opened even when ipvsadm service starts?

Can you help me, anyone?

Thanks,
