Hi,
I'm new to LVS and i need some problem to solve and i don't know if LVS
is the solution to my case...
I have read almost all the HOWTO and the mini HOWTO and, with the help
of the configuration script i could put a simple test up, using DR and
VS with one NIC and one Network (is what i have at the moment).
I have 3 identical machines to use for this test, one director and 2
realservers. All are running Red Hat Enterprise WS 3 update 4. I have
found the ipvsadm and arptables packages ready for this distribution and
everything works as expected, at least in the beginning.
I can, using another machine on this network, connect by telnet (the
test service) to each realserver trough VIP using VS_NAT. but it only
works on the same network and i have here a network a bit complicated.
I need to set a little cluster to serve XDMCP ( I read the HOWTO, i know
about the limitations ), but my clients are on different networks, as we
can see below:
client net 1 client net 2 client net 3 ... client net N

REALSERVER 1 REALSERVER 2 ... REALSERVER n
Sorry about the drawing ;-)
I hope someone understand what i want. The clients must get the servers
on the cluster network. When i use VS_DR i cat get to one realserver
from the client network, but as i see it is going directly to the
realserver, because it doesn't appear at ipvsadm connection list as
appear when i connect using a client in the cluster network.
I tried to deal with the arp problem using the arptables solution, but i
don't know if it is part of the problem.
Please, if anyone can give me a tip on this, will be great!
Thank you all,
