My worker is still not recognized as active on suprnova using ccminer. I have -f 256 and ccminer receives work. My sharerate and hashrate are both 0.
Do you have accepted shares ? Check in Your Account/Workers tab if the worker is active there
No.
Is the miner considered inactive until at least 1 share is accepted?
I've been mining for about half an hour with -f 256, I would have expected to have at least one accepted share by now.
