Hello,
This is my first attempt at setting up an LVS. Pleasse forgive me if I am
being a bonehead.
I have three machines, all on a private network:
"Client:"---------------
192.168.168.5
-----------------------
"Director:"---------------
[root@wee2 httpd]# ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:90:27:32:23:07

--------------------------
As per man page, on the Director, I did:
[root@wee2 httpd]# echo 1 > /proc/sys/net/ipv4/ip_forward
[root@wee2 httpd]# echo 1 > /proc/sys/net/ipv4/ip_always_defrag
[root@wee2 httpd]# ipchains -A forward -j MASQ -s 192.168.168.0/24 -d
0.0.0.0/0
Then I did:
[root@wee2 httpd]# ipvsadmin -A -t 192.168.168.2:80 -s rr
[root@wee2 httpd]# ipvsadm -a -t 192.168.168.2:80 -r 192.168.168.3 -m
On the Director, before I browse, I did a:
[root@wee2 httpd]# ipvsadm -l
IP Virtual Server version 0.8.3 (size=4096)
Protocol LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 192.168.168.2:80 rr
-> 192.168.168.3:80 Masq 1 0 0
Now on client, I browsed to 192.168.168.2. It hangs and then displays error.
At the same time on the Director, while trying to browse to it I did a:
[root@wee2 httpd]# ipvsadm -l
IP Virtual Server version 0.8.3 (size=4096)
Protocol LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 192.168.168.2:80 rr
-> 192.168.168.3:80 Masq 1 0 1
I am not sure what I am doing wrong. I thought I saw a post about LVS not
working if all machines are on the same (sub)net, but I am not sure...
Regards,
Ivan
