Thank you for the update.
It is not working for me. ( sgminer 5.6.6-l) I can set "stratum+tcp://pool.totallyawesome.party:5333" as pool, algo groestl, user = wallet, pw = "c=MBC". Of course this leads to 100% rejected shares on a stock miner.
but running "sudo ./mbc /dev/null &" makes no difference for me. task is restarting ( you are kicked out of screen ) and you can reconnect after 5 seconds. but still only rejected shares.
Same here. I get all rejects. I changed the difficult to 40*28Gh, but no accepted blocks. Any feedback I appreciate.
