Bitcoin Solo Mining with bfgminer

Question

I am trying to do solo mining with bfgminer but it does not seems to be working

./bfgminer --url 127.0.0.1:18443 --user test --pass test

On bitcoind logs I can see the request logs

2018-05-14T10:36:25Z Received a POST request for / from 127.0.0.1:43312

2018-05-14T10:36:25Z ThreadRPCServer method=getwork user=test

2018-05-14T10:36:57Z Received a POST request for / from 127.0.0.1:43330

2018-05-14T10:36:57Z ThreadRPCServer method=getwork user=test

On bfgMiner I can see the following messages

[2018-05-14 16:10:49] No servers were found that could be used to get work from.

[2018-05-14 16:10:49] Please check the details from the list below of the servers you have input

[2018-05-14 16:10:49] Most likely you have input the wrong URL, forgotten to add a port, or have not set up workers

[2018-05-14 16:10:17] Pool: 0 URL: http://127.0.0.1:18443 User: test Password: test

Any help

Answer 1

The error messages you see are exactly what you get if you just start bitcoind without any proper configuration.

Did you make sure

• you started your bitcoind with the -server flag at all? Only that will prepare your bitcoin node to allow connections from external workers such as bfgminer.
• you waited for it to sync with the network? That can take up to some hours

Answer 2

first if your url is not on a mining server your not going to be able to mine (and probabalistically there may be a way but anyway). it would look closer to -o stratum+tcp://emc2.suprnova.cc:3366 and the 127.0.0.1 should be an API address not the url. second, for everyone who is looking for help with BFGMINER if you do not: export GPU_MAX_ALLOC_PERCENT=100 export GPU_USE_SYNC_OBJECTS=1

then it probabalistically will not work as well. The export commands sync bfgminer immediatly to my gpu: ASUS GTX 1080 and starts hashing around 900 k/hs.
