Today I downloaded Parity for Windows.
Start it with parity --author 0x9999999999999 --rpc --rpcaddr 192.x.x.1 --rpcport 8545.

Then I have started ethminer ethminer -G -F 192.x.x.1:8545

When I go to parity's interface I see the best block sync with etherstats, but no commit on next block. Why?

Thanks a lot.

--author requires an argument: you must tell it what the payout address is.

e.g. parity --author 0x1234567890123456789012345678901234567890 --rpc --rpcaddr 192.x.x.1 --rpcport 8545

For what it's worth, Parity enables RPC by default on 8545 - you only need:

parity --author 0x1234567890123456789012345678901234567890 --rpcaddr 192.x.x.1

  • --author was followed by my account. I removed --rpc but no commit on next block . How do I know if I'm mining correctly. Which Feedback?

  • Please rephrase the original question with complete information (i.e. don't skip CLI arguments and explain thoroughly what you mean by "but no commit on next block"). Alternatively join the Gitter chatroom and get an interactive diagnosis.

    parity doesn't give such an output message (i can consider adding it if you feel it's very useful). you should see a message in ethminer saying that there's a new work package - that indicates that parity has moved on to the new block.
