How is hashrate calculated when all you know is luck/shares/difficulty?

I am having trouble getting eth-proxy to do anything.

I am using phoenixminer and pointing all rigs to a machine on my LAN which hosts eth-proxy.

The proxy starts up just fine and it connects to my pool and starts waiting for jobs.

But when the rigs are pointed at it, nothing happens.

It sits there for a few minutes not really doing anything and then a timeout of some sort occurs and it all starts over again.

It's worth noting that I'm using the original Atrides/eth-proxy, which hasn't been touched in 5 years. There are 226 forks of that project. I'm worried that I need to be using one of the forks instead of the original.

If that's not the problem, it's got to be phoenixminer params or the config file settings.

Can someone who's using eth-proxy with success please provide details about how they got this working?

Thank you.

I'm coming from another rentals website, which makes selecting a duration easy. It's not immediately clear how that's done on nicehash.

Anyone have any experience selecting a specific number of hours for a rental on nicehash?

It almost seems like nicehash is forcing me to accept a duration that they set, which can't be right.

I've been waiting on nicehash tech support to answer this for a few days.

Was hoping to hear from someone in here who's actually done it.

I'm sure it's something simple, but it's not immediately obvious in their ui... at least to me.
