I want to try to mine ethereum. Its only a Test if it's working. I am new to Ethereum. I am only mining Bitcoin.
So I installed the ethereum miner.
And want to mine in the f2pool.
In the help "Simply point your stratum-compatible miner to
etc.f2pool.com:8008, and set your ethereum account as login"
So I tried (my username is wiraport) whats about the password
ethminer -F http://etc.f2pool.com:8008/wiraport -C -t 4
I got the following error.
13:05:58.486|ethminer Getting work package... ✘
13:05:58.981|ethminer Failed to submit hashrate. ✘
13:05:58.981|ethminer Dynamic exception type: jsonrpc::JsonRpcException std::exception::what: Exception -32003 : Client connector error: libcurl error: 56
Whats that and how can I fix it?
