Hi everyone,
I am happy to say that LVS-NAT works pretty well in my test servers. The
howtos are very thorough, though I have a couple of questions. I'm
including my setup script as an attachment. Maybe you can point out
anything bone-headed I have done.
First, ssh connections get reset if there is no activity after 5 minutes
or so. At first, I thought persistence was what I wanted, so I set it to
1800 on ssh. However, that's silly as I now know, since persistence
refers to giving a client the same real server within the persistence
time. Or so I'm lead to believe. Any ideas? I'm now trying to remove
persistence to see if that works. I don't know why that would affect
it though. Direct ssh doesn't disconnect in any case.
Second, anyone want to recommend the best MTA for a LVS system? I'd like
mail to be delivered into users' home directories that are shared over
NFS. So far, qmail looks the best, though I'm just now trying to learn
its eccentricities. Postfix and sendmail don't seem to like delivering
over NFS very much.
Third, just wanted to let everyone know that LVS works with the latest AC
kernels, though you have to comment out EXPORT_SYMBOL(buffermem_pages) in
kernel/ksyms.c, since it's defined elsewhere in AC's version. No, the ssh
timeout isn't tied to this kernel, since I tried it with stock Linus
versions first. AC just had some patches that my redirector/routers liked.
Thanks,
Brent
