Hi

If anyone can suggest a solution to my problem that works I will pay 20 BTC you can check my record of payments here...

Anyhow, I have pushpoold and namecoind running on all 3 servers. Each server has a copy of my wallet and virtually identical. The domain name NMCBIT.COM is set to Round Robin all 3 servers and some people get lots of "unknown-work" rejects. http://www.nmcbit.com/statistics

My guess is they bounce from one server to another requesting work from one server and submitting it to another server.

My guess is that I have a) create a DNS b) create a proxy server to forward requests.

I am hoping for a more simple solution.

Is there a reason to have it on all 3 servers?

If you're set on it, then here's what I would do:

The first time you get something from a specific IP, have a proxy assign it to one of the servers (round robin style).
If you really want to get tricky, have it update a DB with last contact from that IP and then every however often you want have a cron job clear the DB of entries older than an hour or so.

This won't give you a perfect load balance, because people will have a different hash rate... but it'll balance somewhat.

Another option is to show the stats of the 3 servers on the website and let people pick for themselves.

Thanks for the suggestions they are all good and I wish I had the time implement just one but I am looking for a faster solution. As for why I have more than one server? Well there are 2 reasons...

1. I am using Amazon EC2 micro VMs.
2. Bitcoin growth is explosive I want to be ready to just add servers should that happen to me
3. (I know I said 2) It's fun to play with clustered servers.

I guess there is no options or settings or out of the box software I can use to fix this?

I'll talk to some people at work today and see if there are any easier options (do a lot of networking stuff).

Thanks!

Check out my stats page.

http://www.nmcbit.com/statistics

you can see the one person has HUGE percent of rejects while everyone else including me has very tiny percent of rejects. Weird. Checking the DB I do get a few "unknown-work" rejects in fact most of my rejects are "unknown-work". Also flushing the DNS cache on my PCs constantly does not cause the unknown-work problem.

Perhaps my miner software submits the requested work to the same server unless it can't get to it. I don't know I am just guessing.

Took me a bit of thinking to find the name but I knew someone had done it! What I was looking for is called TCP/IP Relay!
A product called balance works perfectly for bitcoin:
