Installing NOMP.

[educob]

Hello,

I have a private bitcoin network (2 nodes connected among themselves)

I am installing NOMP according to this guide: https://github.com/zone117x/node-open-mining-portal

When running "node init.js" I get these errors:

Code:

Any idea what is wrong?

Thanks.

Thanks.

Would you post your config. Omit credentials pw/usr as necessary. Thanks

Edit. Try setting your website to port 81 in the config.  Also. It’s been quite a while. I’m not certain if the blockchain needed to be synced for it to load correctly. I’m not where I can look at the code

Thanks.

Update.

I found this thread: https://stackoverflow.com/questions/9164915/node-js-eacces-error-when-listening-on-most-ports

The solution is to allow, somehow, port 80 for non-root users:

Code:

sudo apt-get install libcap2-bin
sudo setcap cap_net_bind_service=+ep `readlink -f \`which node\``

But now I get this:

Code:

I have two bitcoins nodes connected among themselves (a private mainnet) and I want to start mining.

How do I know the pool is mining?

Thanks.

Best thing to do would be to get it setup on a testnet so that you can see if you find blocks.  Wait till your daemon is synced.  Problem with bitcoin is your going to need so much hash power it’s not worth it to hope you have it right.  If your looking to mine solo btc checkout ck solo pool.   If your looking to learn then I’d suggest keeping it internal within your network. Thieves will clean your pool so quick it’ll make your head swim.

Hi.

Thanks for answering.
The bitcoin network is private. Mining souldn't be a problem at all.

The thing is that I installed a mining server but I haven't seen an explanation of how to use it.
It seems that most documentation assumes some kind of magic learning by readers.

How do i mine?

[educob]

I am running cpuminer (please see above the configuration files):

Code:

./minerd --url=stratum+tcp://127.0.0.1:17117  --userpass=3KFHKvFjjfcNYsWRJz8Bt8TtWSrLsC7Neh:yyy  -a sha256d -D -P

And I get this error:

Code:

[2018-10-24 00:34:35] > {"id": 1, "method": "mining.subscribe", "params": ["cpuminer/2.5.0"]}
* Failed to get recent socket
[2018-10-24 00:34:35] stratum_recv_line failed
[2018-10-24 00:34:35] ...retry after 30 seconds

No idea if the port is 17117, or 3333 or 3008.

Sometimes I get this error in the terminal running "node init.js":

Code:

/home/vader/.bitcoin/nomp/libs/poolWorker.js:278
                            pools[currentPool].getStratumServer().handleNewClient(socket);
                                                                 ^

TypeError: Cannot read property 'handleNewClient' of undefined

Please help me.

Your mining port would be the 3008 port. If you are mining the same machine you are running NOMP use 127.0.01:3008 for mining address. Otherwise if it’s same network use whatever you config your network with. 10.10.10.5:3008 or 192.168.1.5:3008 for example. See if that gets you connected and talking to stratum. FYI Cpu mining bitcoin isn’t going to work for you at this point. Difficulty to mine a block is 7 trillion. Not impossible but improbable. Your going to be submitting shares to the pool that exceed a difficulty of 8.  Chances to mine a block bitcoin with cpu is prolly about 1 in 10000 years. Maybe worse. Odds aren’t in your favor.
