ETC consecutive shares rejected by the pool

[david739]

hello, I have a problem with ETC, it keeps writing to me on the miner (consecutive shared zamita pool) the coin is displayed and the work goes on, but the hash of the miner is not displayed on the website

[pool2mine]

Not 100% sure, but as far as i remember, Miningcore has no support for ETC yet. Remember ETC hardforked and changed algo a couple of years ago to ETCHASH

[david739]

Does anyone know how to set it up to make it work?

Has anyone managed to get it working?

[pool2mine]

I never got it working with miningcore... I had to fork the sammy's version that official ETC profile has, then added nicehash support and some other custom stuff i needed. it is easier to start with their repo as they already added ETCHASH support

[jon4hz]

#1514 adds support for ETC (not merged yet though)

[david739]

hello, I copied the data and checked the source, it should fit according to the instructions, but I still have something wrong, can someone please help me

That's definitely the wrong epoch. What chaintypeoverride did you use in the config.json?

[david739]

[david739]

hello, I didn't change config.json, there is no information in the instructions, what should I change there, please

[jon4hz]

try to add "chainTypeOverride": "Classic" in the pool config.

[david739]

hi you mean like this
config.scheme.json

"integer",
"null"

Are you running on windows? (looking at the logBaseDirectory)
Not sure if windows is fully supported.

The config looks fine imo.

[david739]

i have ubuntu it's just a bug so what now

[jon4hz]

Maybe @blackmennewstyle can help you out. He wrote that code :)

[blackmennewstyle]

The POW algorithm etchash needs the DAG files located in that directory in order to work properly and validate the shares it receives from miners. If you does not specify the path for that directory in your config.json, your shares will always be rejected.

Also, what do you mean by bad trigger with geth?

[david739]

that will be it can you please provide an example in the source code

[david739]

I already put it in there, but the file classic.toml is empty, does anyone know what the source should be in it

"chainTypeOverride": "Classic",
"dagDir": "/home/xxx/.ethereum/classic/geth/classic.toml",
"daemons": [

[blackmennewstyle]

Out of curiosity, are you trying to run your ETC pool with the source code currently available on https://github.com/oliverw/miningcore?

[blackmennewstyle]

I feel like i misunderstood you since beginning, so my bad.

So like @jon4hz warned about, the source code currently available on https://github.com/oliverw/miningcore does not support ETC with etchash, it has not been merged yet. So if you want to have support for ETC with etchash, you need to use my fork https://github.com/blackmennewstyle/miningcore.

Also, you need clearly to read the geth documentation in order to be more familiar. The .toml file is a configuration file for geth, you need to generate it. It allows you to run the node without the need of specifying one hundreds options.
Once you generated that .toml file, it will contain a line like this one DatasetDir = "/home/ceedii/.etchash". It's the path to the directory which contains all the DAG files, it's the one you can use for "dagDir":.
However, if you are in a situation where miningcore and geth are not running on the same server. You can arbitrarily create a folder on the server which runs miningcore and specify the path to that folder inside "dagDir":. miningcore will automatically generate the necessary DAG files. Just make sure that the user which runs miningcore has read and write access on that folder.

[david739]

ok i will do everything and let you know

[david739]

I would be grateful for the procedure how to generate .toml

[jon4hz]

I don't think that is neccessary at all. dagDir is an optional parameter (or at least was until now).

What stands out is that your pool tried to generate the dag for epoch 562 which is wrong. Etc is on epoch 280.
But that should have anything to do with the directoy where the dag is stored.

[david739]

ok, and how should I generate 280, it still generates 562, it wouldn't be possible to fix something

./geth --classic --maxpeers "350" --cache "8192" --allow-insecure-unlock --miner.etherbase "xxx" --unlock "xxx" --password ~/pwd --mine --http --syncmode "fast" --http.api "admin,debug,web3,eth,txpool,personal,ethash,miner,net,trace"

[blackmennewstyle]

Please, can you answer which source code you are currently using? https://github.com/oliverw/miningcore or https://github.com/blackmennewstyle/miningcore for running your pool?

[david739]

yeah sorry I'm trying yours now https://github.com/blackmennewstyle/miningcore

[david739]

I got 280 on yours, it's starting up now so we'll see

[david739]

so your system works without a problem thank you thank you and 1 more thank you

[blackmennewstyle]

You're welcome. So you were just not using the correct source code. Congratulations :)

[david739]

well, I didn't know about yours, I kept remaking the other system, too bad, but at least I learned something
