Dear List Members,
Since last three days i am trying to implement LVS through Piranha under
testing but unfortunately i have no success.
I have configured lvs.cf via piranha web interface and followed all
instruction provided by the RHEL5_Virtual_Server_Administration.pdf for
direct routing as well as NAT routing.
My problem is pulse daemon is getting started properly and ips are also
getting alias in Ethernet interfaces but when i am firing netstat command to
see if port is listing as per my configuration then netstat command is not
showing any port.
My lvs.cf and netstat is attached.
ipvsadm output:
[root@lvs1 ~]# ipvsadm -L -n
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags

}
}
I am unable to send port 80 traffic to its public ip as port is not listing.
Please help...
For you info i have tried nat and direct routing both and no luck.
