Hi all,
Here I am giving more details. I have one director. and two real
servers.
director(eth0:172.16.30.75& gateway 172.16.0.1, eth1:10.1.10.9 &gateway
10.1.10.100,
eth0:0 172.16.30.76 & gateway 172.16.0.1).
server1(eth0:10.1.10.10, gateway 10.1.10.100)
server1(eth0:10.1.10.11, gateway 10.1.10.100)
All are Redhat 6.1 distributions.(kernel -2.2.12-20)
I am using ipvsadm 0.8.3.
--------------------------------------------------------
[root@director /root]# ipvsadm -L -n | head -1
IP Virtual Server version 0.8.3 (size=4096)
------------------------------------------------
[root@director /root]# ipvsadm -h | head -1
ipvsadm v1.1 1999/7/1
-----------------------------------------------------------
I connected the eth1 of director and eth0 of both server1 and server2 to a
hub. yes I got a hub yesterday night.
I connected the eth0 of director to my LAN(gateway 172.16.0.1). So It is
nothing but the setup given in LVS-NAT diagram.
I gave the following commands :
-----------------------------------------------------------
echo 1 > /proc/sys/net/ipv4/ip_forward
/sbin/ipchains -A forward -j MASQ -s 10.1.10.9/8 -d 0.0.0.0/0
ipvsadm -A -t 172.16.30.76:23 -s wlc
ipvsadm -a -t 172.16.30.76:23 -R 10.1.10.10:23 -m
ipvsadm -a -t 172.16.30.76:23 -R 10.1.10.11:23 -m
--------------------------------------------------------------------
My director is having two ethernet cards. The ifconfig output is :
----------------------------------------------------------------------------
-----------
eth0 Link encap:Ethernet HWaddr 00:A0:C9:CC:97:2E
inet addr:172.16.30.75 Bcast:172.16.255.255 Mask:255.255.0.
eth0:0 Link encap:Ethernet HWaddr 00:A0:C9:CC:97:2E
inet addr:172.16.30.76 Bcast:172.16.255.255 Mask:255.255.0.0
eth1 Link encap:Ethernet HWaddr 00:80:48:EE:E7:3E

lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
------------------------------------------------------------------------
and server1
eth0 inet addr:10.1.10.10 Bcast:10.255.255.255 Mask:255.0.0.0
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
-----------------------------------------------------------------
and server2
eth0 inet addr:10.1.10.11 Bcast:10.255.255.255 Mask:255.0.0.0
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
----------------------------------------------------------------------------
----------
ipchains -L gives the following
-------------------------------------------------------------
Chain input (policy ACCEPT):
Chain forward (policy ACCEPT):
target prot opt source destination ports
MASQ all ------ 10.0.0.0/8 anywhere n/a
Chain output (policy ACCEPT):
--------------------------------------------------------------
ipvsadm gives the following
---------------------------------------------
[root@director /root]# ipvsadm
IP Virtual Server version 0.8.3 (size=4096)
Protocol LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 172.16.30.76:23 wlc
-> 10.1.10.11:23 Masq 1 0 1 <<<------- It is
showing the connection as inactive when I tried from a
client on LAN
-> 10.1.10.10:23 Masq 1 0 0
----------------------------------------------------------------
My problem is that I could not connect from any client to the virtual IP
when I try to connect from any client in tha LAN.
I hope this helps to help me.
thanks in advance,
madhav
