I have a NerdMiner_v2. Since OP doesn't want such low hashrate devices connecting to his ckpool (that's completely understandable, no coplaints here on my side), I figured I would try to run my own backend as I have one VPS that is pretty much getting bored and is already running bitcoind.

I compiled OP's solobtc from https://bitbucket.org/ckolivas/ckpool-solo/src/solobtc/ , I have bitcoind configured in server mode and running, ckpool (solobtc) tools is running, my NerdMiner_v2 is connecting and hashing. However, there are some (I hope) minor issues.

Firstly, I see the below messages about failing to set the desired rcvbufsiz, in the ckpool log at logging level 7:

Code:

Since it complained about unprivileged user, I tried running with sudo and got the below:

Is that something I should address, if so, how? Should I always run it as root (that does not seem smart to run internet exposed code as root)?

Second thing is, if I run

Code:

ckpool -B -l 7 -c /mypath/to/ckpool.conf

I see one (my) client connected but it reports zero hashes/sec.

Code:

0.00H/s 0.0 SPS 1 users 1 workers 0 shares 0.0% diff

and the ckpool.log says it's "Skipping user" of mine, "Failed to parse suggest_difficulty for client 1" and reports in idle stats. See below. What's the problem?

Oh, and by the way, if OP really doesn't want so low hash rate devices connecting to his ckpool, I would suggest reaching out to authors of the NerdMiner_v2 software here https://github.com/BitMaker-hub/NerdMiner_v2 as ckpool address is a default option there.

He advises against it, he says its a waste of time, he says they use the same amount of resources from a big miner for a small miner. But I also seen him say he will not stop/disable it. Correct me if I'm wrong but it is allowed he is just very clear your wasting power and time. It is still random!
