Hi,
A friend of mine has 2 lines of 512kbps terminated in two Linux boxes.
He now want to remove those 2 boxes and have some device which will
loadbalance the two ISPs and also have a failover arrangement. But he
has agreed to give me a chance to do it on Linux for my own
satisfication.
Is this easy to do with lartc? How do I go about it exactly? I have
very less time to do it since his whole network will be done for that
time and I cannot afford to play for long time. Is it worth trying it
with lartc for academic sake atleast?
Can someone suggest some easy steps?
With warm regards,

p.s. Is lartc.org down?
You can try out implementing configuring a load balancing and failover
system referring to the following documents:
http://www.ssi.bg/~ja/nano.txt
http://www.ssi.bg/~ja/dgd-usage.txt
You will need to patch and recompile the linux kernel using the "routes"
patch given at http://www.ssi.bg/~ja/#routes for dead gateway detection
to work.
The load balancing part works fine but dead gateway detection (and hence
failover) does not work always. It works best when your first hop
gateway is down but may or may not work when a subsequent hop is down.
In a recent case, I observed that dead gateway detection and the
failover was working very well when one ISP failed but did not happen
when the other one went down. So you can try your luck here.
