Hi,
I am glad to see you have it working, any suggestions what I did wrong? Please have a look at my setup below.
LVS on RedHat 7.2, here is my setup:
________
| |
| client |
|________|
CIP=10.1.1.90
|
|
|
VIP=10.1.1.1 (eth0)
__________
| |
| director |
|__________|
DIP=192.168.4.128 (eth1)
|
|
-----------------------------------
| | |
| | |
RIP1=192.168.4.1 N/A (yet) N/A (yet)
_____________ _____________ _____________
| | | | | |
| realserver | | realserver | | realserver |
|_____________| |_____________| |_____________|
mask on the local net /24,
default gateway on realserver 192.168.4.128
=======
content of: /etc/sysctl.conf
# Disables packet forwarding, 0 is disabled, 1 endabled
net.ipv4.ip_forward=1
# Enables source route verification
net.ipv4.conf.default.rp_filter = 1
# Disables the magic-sysrq key
kernel.sysrq = 0
# Enable automatic defragmentation (needed for masquerading, LVS)
net.ipv4.ip_always_defrag = 1
=======
here is my experimental setup that I am trying to get to work,
firewall WIDE open
===========
iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -F INPUT
iptables -F OUTPUT
iptables -F FORWARD
iptables -t nat -F
iptables -t nat -A POSTROUTING -s 192.168.4.0/255.255.255.0 -j
MASQUERADE
ipvsadm -C
ipvsadm -A -t 10.1.1.1:80 -s wlc
ipvsadm -a -t 10.1.1.1:80 -r 192.168.4.1:80 -m
===========
Here is what happens:
1. I send an http request from client (10.1.1.90) to 10.1.1.1.
2. the packet is accepted by the LVS and a request is sent to the real
web server, ip:192.168.4.1.
3. The real web server DOES send a response back to the box running
the LVS server. I can see it on eth1 with "tcpdump -i eth1"
4. I never see the packet again, somehow it gets lost on the machine
and never returns to the Client.
There is obviously something I missed. Any suggestions?
Kind regards,

Hi,
I ve got a LVS setup on a redhat 7.2 server, i was trying 2.4.9 and 2.4.12
kernel.
At this time i haven't been able to got a stable configuration. Server freeze,
kernel panic ...
(see kernel panic on this list last days...).
I am planning now to downgrade to redhat-7.1 and kernel-2.2.19.

Hi,
I am
looking on some advice on how to setup LVS on RedHat 7.2.
From
what I have noticed, this version of linux has all the required modules already
available in the distribution. Does anyone have any advice on how to
implement LVS on this distribution? It appears that all the documentation
and HOWTOs reference the old ipchains (am am using iptables on the server) and
old kernels.
Kind
regards,
Adam
