Hello,
I just started to try LVS recently.
I can't start service of ipvsadm.
The diagram is below:
=======================================<
ClientPC(192.168.1.103)

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@fedora3 ~]# ipvsadm -A -t 192.168.1.70:http -s rr
[root@fedora3 ~]# ipvsadm -a -t 192.168.1.70:http -r 192.168.1.90:http -m -w

=======================================>
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,
