I've setup a local stratum server using eloipool. I'm trying to test the stratum server manually using either telnet or curl as in:

curl --data-binary '{"id": 1, "method": "mining.subscribe", "params": []}'  -H 'content-type:text/plain;' http://myuser:[email protected]:3334/

The connection is closed as soon as the first line of the http headers is sent (usually POST) (curl prints: curl: (52) Empty reply from server)

Any idea of what's happening?

Ha! That worked... some massaging but, I got it 
Now to test it 

And on we trudge.

Its the Unicode issue, Twisted library is a pain to use in 3.x since python changed default handling.
If I leave out the MerkleTree import, then I can use Python2.7.
Please advise if the MMP absolutely needs the MerkleTree import.     

Wait, wait, looked at the code, it says only 1 subchain will work, interesting...
So, really do have a delema here... I have to make 1/2 work in v3 which I have already managed, and 1/2 work in v2 for MMP.

And on we trudge.

Ah! I just had to restart after all the installations.
Owh, Wait, But what do we have here.... Another error 
Communications between the MMP and Eloipool are broken, I think the script has serious issues in Python3.
Its going to take week to sort this out since in know precisely nothing about Python 
Sure, just buy some hardware, plug it in, hash away, and bank some crytpo coins, humff.

I guess what I really need is a working tested Python 3.2 or 3.x version of MMP so I can merge in the changes.

MMP uses Twisted library, which seems to be having an issue.
I still keep getting the following when eloipool sends gotwork to the MMP.


  
  
    

No Such Resource

    

No such child resource.

  


Still debugging, any suggestions?
Using Python3.2
Twisted 14.0.2
NOOBS RPI
Not using twistd dont think I need it.

 

And on we trudge.

Still working on it... (Looks now like the target was set so high I always find blocks =/ so, no worries)
More clues:

Posting "method": "gotwork" i get:


 
 
   

No Such Resource

   

No such child resource.

 


trying to debug it.
I'm guessing it means I did something odd.
I'm using Python3.2 and a couple of these script seems to have needed a conversion from 2to3 via the 2to3 app.
Perhaps I should do that to all of them...

And on we trudge.

I started at the beginning of the forum and found my answer he he he  

I'll go ahead and re-post it here:

Thanks Luke!

client miner <--> eloipool <--> bitcoind
                     |-> merged mining proxy (MMP) <--> namecoind

merged-mining-proxy:
python merged-mining-proxy  -w 8330 -p http://ssecreteloipool:[email protected]:9947/ -x http://namecoinrpc:manecoinrpcpass@localhost:9377/

eloipool config.py:
# Secret username allowed to use setworkaux
SecretUser = "ssecreteloipool"

# Addresses to listen on for JSON-RPC GBT/getwork server
JSONRPCAddresses = (
        ('', 9947),
)

GotWorkURI = "http://mergedproxyuser:[email protected]:8330/"

namecoin config:
rpcuser=namecoinrpc
rpcpassword=manecoinrpcpass
rpcport=9377

and user miner program connect to 9947

Attempting the above, stand by......

I managed to get it to work by replacing all INET6 with INET.
I am good at this point.
I have a new error, not sure if it is component configuration related or not...

I found a scrypt version of eloipool and im trying to merge-mine litecoin and dogecoin.
I think the configuration is...


Miner -> Eloipool -> merged-mine-proxy -> litecoin wallet + dogecoin wallet.

Please confirm if I have this conceptually correct.
I think the setworkaux is missing in the wallet, so, I suspect I need to modify the wallet code?
I am confused because I saw setworkaux in some of the pool code to as though my componets above might not be correct.
Please confirm.

                Thank you in advance 

 

Eloipool only supports IPv6.
If you want to use obsolete IPv4, you will need an OS that supports IPv4 connections on IPv6 sockets (like Linux) and configure it to bind on the appropriate iPv6 address (as in the example config).

Owh, okay I found another version of the pool with slight modifications containing the scripts I need for scrypt.
(pun intended) 

Owh, I also had to fix /home/pi/eloipool/bitcoin/node.py for the NET6 issue.

Okay, almost there. I have another error, I think it has to do with configuration (trying to get this to work for LiteCoin).

I changed everything in networkserver.py from AF_INET6 to AF_INET.
That error seems to be gone, but my miners cannot connect?!
(yes I also changed the config file removing the ::ffff:)

If there another log I should look at?
The process is indeed running, the miners are saying connection refused.

    

I am hopefully on my last error but, since I have not seen any of the errors above this line, I am skeptical this will be the end-all.

Hello, I am seeing a bug, tried changing my hostname already, that was not the cause.

I stuck in the same problem for days. I'm using ubuntu 14.04, I tried both bitcoind v0.9.2.1 and v0.9.3rc1 and nothing is different. Can anybody tell me what should I do. Thank you.

Sounds pointless, since addresses should only ever be used once.

Thanks for the info Luke.
NOMP mining key creates a pubkey/privkey pair that can be used for any coin - the coin's pubkey can be derived from the mining-key pubkey, and likewise for the privkey.

Allows zone117x to collect from coinbase on pretty much every coin folks mine with his solution. And also, this is part of the magic in nomp that allows for multipools - coinswitching ports require mining-keys for usernames, and payment processor pays the coin to the derived coin pubkey

I don't have one running ATM, but raskul has his here: http://eu.centralcavern.uk:8080 the mining key creation web script is here http://eu.centralcavern.uk:8080/key.html - his setup looks pretty stock.

The loop branch was never finished and does not work completely.
Use it at your own risk...

Be sure miners are using the latest version of BFGMiner.
Unmaintained versions and forks thereof, my have bugs - those are however unrelated to Eloipool.

Nope, no idea what you're talking about.

The sample config file has a Coinbaser example that donates.

Luke-Jr, we've been running eloiopol to connect a pool to eligius, quite successfully (Thanks!) and have a few questions:

1) To connect to an upstream pool (ie eligius) the loop branch is required
    - If I understand everything, I need coinbase/append and submit/coinbase to do this, and those don't appear to be in the main branch, correct?
2) I also need the latest version of your bitcoind, eligius branch? (it's what I am running now)
3) when using this branch, so I need or want "BlockSubsissions" section, or just "UpstreamURI"
    - and if I need/want it, mining on upstream pool like eliguis, whose servers should be here?

- FWIW, we're using your suggested commit for bitcoinrpc, and mostly everything else you suggest, except gentoo (I feel like I might have shot myself in the foot here!) eloipool is running in a fairly stock ubuntu14.04, with python3.2 and setup in virtualenv.

The issues I've seen so far seem common, and mostly above you suggest ignoring most, but

- when stratum workers become disconnected, they don't want to reconnect without the human restarting miner software
- they seem to disconnect when we see a socket timeout connecting to (either eligius or our own bitcoind, this is not clear)

Finally, is there any guidance on the amount of RAM required to run eloipool as a downstream pool? Is this more based on the number of workers connected, the amount of hashrate, or?? I definitely ran a 4GB box out of RAM with just 2THs on it. Bitcoind is running on it's own machine, and we're just logging shares to text for now.

Well. Maybe one more. I'm sure you've seen nomp's mining keys? What do you think of this idea and code? And, if you think that's a good idea, would that be something you'd have an interest in supporting in eloipool? (maybe a module that figures a pubkey from a miningkey and drops it into config.py?)

I know you're not the biggest altcoin fan, but I can't see any reason you shouldn't earn something from pools using your software to mine them. (forrestv has something similar for --give-author in p2pool I've not seen how this works though)

Thanks for your time! (we know where to put some BTC )

Luke-Jr,

By chance would you know off the top of your head what could be causing my target issue posted a couple above?

Update: Nevermind, found out the var diff part was not in the master that I pulled.  Works like a charm now.  Big thanks to Polyatomic for pointing me in the right direction!
