I am playing around with bitcoin mining. I have set up a full node on an ODroid C2 device. I am running Ubuntu 16.04 and Bitcoin core. That seems to be running find. It is keeping up with the block chain with no errors.

I downloaded the cpuminer source and built it without errors.

When I run it it starts up the 4 mining threads, but always gives and error that the host returned a 404 error.

I have the rpc set up and am using the correct username and password.

I am using the default ip address for localhost and the default port of 8882.

Can someone explain what I have done wrong that minerd won't connect to the local bitcoin node?

The ability to solo mine was removed some time ago. You have to set up a stratum proxy server.

  • Mining code (setgenerate) was removed from Bitcoin Core itself, but the API (getblocktemplate) to interface to an external program for solo mining still remains. In principle it should be possible to use it, so I think OP's problem is something else. – Nate Eldredge Jun 17 '18 at 5:02
