Joseph,
Thanks!
Did you mean this:

But this looks like an integrated solution, hardware and software. I am just looking for the software part.
Boris.

Hello all,
The question is not necessarily CentOS-specific - but there are lots of bright people on here, and - quite possibly - the final implementation
will
be on CentOS hence I figured I'd ask it here. Here is the situation.
I need to configure a Linux-based network load balancer (NLB) solution.
The
idea is this. Let us say I have a public facing load balancer machine
with
an public IP of, say, 50.50.50.50. It is to receive the traffic (let's
say,
HTTP traffic) and then route it to two private HTTP servers, let's say, 192.168.10.10 and 192.168.10.11. It has to have persistence - i.e., be state- and session-aware. If for whatever reason one of the servers
goes
down the remaining pool shares all the traffic in some fashion (be it
eound
robin, saturation based, whatever).
We have tried Vyatta ( http://vyatta.org/ ) and ZeroShell ( http://www.zeroshell.org/ ) and both are very good but their NLB seems
to
be externally facing (i.e., you have several internet connections and
are
trying to divide your traffic between them). What we need is an
"internally
facing" one, if I may say so.
Any advice on what may help us would be greatly appreciated.
I've had pretty good luck with Barracuda load balancers.. You can configure them to keep a user session on a single server, which is often desired, and spread new connections to other servers as they arrive. The only problem I had with them, ironically, was they would crash if I purchased their "Live Updates" feature. It's some sort of auto updating black-list service you can buy which helps protect the device and your resources. But after I disabled that, the device has been rock solid. Been working great since about 2006.
If life gives you lemons, keep them-- because hey.. free lemons. "~heart~ Sticker" fixer: http://microflush.org/stuff/stickers/heartFix.html _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
