Hello..
Forgive me if this has already been explored recently; I checked the FAQs
and archives and did not find a good thread on the topic.
We are doing something very similar to LVS, except using Foundry
ServerIronXL load balancers on the front end with a heterogeneous cluster
of servers on the backend. We are migrating to 100% Linux 2.4 slowly. We
have things working nicely for the most part with our SGI IRIX servers, but
the Linux 2.4 servers (Redhat 7.2 stock SMP kernel) do not seem to support
DSR/Switchback (e.g. bind the real IP to the loopback or dummy interface
and have the hidden server reply directly to the client, without NAT or
involvement of the front-end load balancer).
I have spent quite a bit of time trying to get this working, but can't for
the life of me figure out what is wrong. If anyone has any experience or
thoughts with DSR/Switchback & Linux 2.4, please email me off list (or
reply to this thread if it is of general interest) as I could really use
some expert advice.
Thanks in advance,
-- Jared
