Release: Stratum-Proxy for Ethereum
 
About 10-20% growth in earnings in comparison with the other standart pools

What is it?

This is Stratum Proxy for Ethereum Pool using asynchronous networking written in Python Twisted.
Equal solo-mining, different is that is a stable effect and not just a variable luck.

The Beta-version (v0.0.3) Download here and compiled version for Windows

Stratum port on the pool 8008, on all servers
Parameters change in config.py (there are ports, wallet and email)

Features:

  • the only one connection to pool
  • proxy get the new work from the pool as soon as the new block appears. There is no need to sent requests to the server permanently (miniers do it usualy 2 times/sek)
  • workers get the work from the proxy locally
  • submit of the shares without network delay, proxy answers to the worker and at the same time sent solution to the pool. There are no network delay, there won't be created the new connections to pool.
  • configuration of the wallet is centralized in settings file, miners do not need to pass it.
  • Bypass worker_id for detailed statistic and per rig monitoring
  • you can put your email in settings to monitor every worker
  • Pool pays out uncle blocks!

How it works?

Code:

   Pool A <---+                        +-------------+ Rig1 / PC1
 (Active)      |                       |                                                
               |                       +-------------+ Rig2 / PC2
               |                       |                                                
  Pool B <---+-----StratumProxy  <-----+-------------+ Rig3 / PC3
(FailOver)                             |                                                
                                       +-------------+ Rig4 / PC4
                                       |                                                
                                       +-------------+ Leaserigs

The command line to start miner with proxy looks like (with worker and without it)
Code:
./ethminer --farm-recheck 200 -G -F http://127.0.0.1:8080/rig1
./ethminer --farm-recheck 200 -G -F http://127.0.0.1:8080/

After many tests I recommend to use farm-recheck=200 with proxy


-----------------------

Requirements
Works only with pools which support stratum-proxy.
Currently works on all DwarfPool servers (EU, US, RU)

How to install?
Proxy developed on Phyton, therefore the dependencies are:
* Python 2.7+
* python-twisted

[Linux]
Code:
1) install twisted
 apt-get install python-twisted
2) start proxy with
 python ./eth-proxy.py

[Windows]

Download compiled version or download as python code:

Code:
1) Download Python Version 2.7.10 for Windows
https://www.python.org/downloads/

2) Modify PATH variable (how-to http://www.java.com/en/download/help/path.xml) and add
   C:\Python27;C:\Python27\Scripts;

3) Install python setuptools
https://pypi.python.org/pypi/setuptools/#windows-7-or-graphical-install

4) Install Python-Twisted
https://pypi.python.org/pypi/Twisted/15.4.0
File Twisted-15.4.0.win32-py2.7.msi (32bit) or Twisted-15.4.0.win-amd64-py2.7.msi (64bit)

5) Install zope.interface, in console run:
   easy_install -U zope.interface

6) Install PyWin32 v2.7
pywin32-219.win32-py2.7.exe or pywin32-219.win-amd64-py2.7.exe
http://sourceforge.net/projects/pywin32/files/pywin32/

7) Download eth-proxy. Extract eth-proxy.zip. Change settings in config.py and start with command:
  python xmr-proxy.py

Known open issue
- shown speed on the site is rough, but the increase can be seen by amount of sent shares

ToDo
- Transmit parameter submitHashrate
- Automatically failover via proxy
- EXE file for Windows, so that it was not be necessary to install all dependencies as described below

FAQ

Quote
Is it possible to give a more detailed description of the principle of the proxy?
If I have 6 rigs, will it use much less bandwidth with the proxy? Does the proxy get a very high difficulty work from the pool and then divide/distribute it to the rigs? If so, how does it divide the work?

For your rigs this proxy looks like a pool.

Proxy set only one connection to the pool (socket) so than inside this physical connection makes virtual connections to the pool for every Rig/PC.

It reduces not only the traffic and submit time, but you have better control and get more coins for you hashrate.
Just put to your miner the proxy as a pool and any username as worker. Your miners don't need any changes more and forever.
If you want to change the wallets or other settings, you change it in config.py of proxy and restart it. Miners will be reconnected automatically.

Quote
The log file grows too fast. Is it possible to disable saving to the file? Can we disable it totally?
Yes, just comment it like here
Code:
#LOGFILE = "logfile.log"

I have a problem I am unable to resolve when mining to DwarfPool.
  • I know my Nvidia card can output ~13Mh/s
  • Command "ethminer.exe -U -M" benchmark outputs ~13Mh/s berformance.
  • I am able to start the Ethminer successfully including -U or --cuda to specify Nvidia card, but the miner does not go over ~7 Mh/s!
  • I have tried the Stratum Proxy successfully, but the results are the same, nothing above ~7Mh/s!
  • I have even tried without the proxy and directly against the Stratum  8008 port with the command: "ethminer.exe -U -S eth-us2.dwarfpool.com:8008 -O 0xWALLETID -SP 1", but still nothing over 7Mh/s!
  • When I try the same miner against MiningPoolHub's eth pool with the command: "ethminer.exe -S us-east.ethash-hub.miningpoolhub.com:20585 -O username:x -SP 2 --cuda", then it mines around ~13Mh/s!

So what's the deal, where is the bottleneck?
Is it the DwardPool's server, because MiningPoolHub can reach these speeds with the same miner?
I have even tried previous version of ethminer.exe, I don't know what else to try.

Thanks!

Any ideas on how to get a worker name issue I am having fixed?

Using ethOS and claymore to mine ETH using a remote config.

Can't get ETHproxy to submit shares using the ethOS assigned rig names.  This would be helpful to easily identify rigs that are crashed / not hashing as my pool sends me email alerts when a worker hasn't sent shares in XX minutes.

Thanks for any help.

Hi!

I have a proxy on one computer on wich I have a VPN so I can mine through our Firewall wich only allows ports http://shrani.si/f/N/oV/4bZtK25r/ports.png

This is ok.

But on the other computer on the same network;

Miner 970L, local IP: 192.168.1.16 (same subnet and all)

conf. file:
ethminer.exe --farm-recheck 200 -G -t 1 -F http://192.168.1.17:8080/970L

response:
http://http://shrani.si/f/34/5s/qYTmY0K/screenshot1.png

I allready tried to turn off the firewall on both computers, but it doesn't help.

What am I missing?

Thanks for helping me Smiley

EDIT:

proxy is working. I tested it with miner on the same computer.

----------------------------------------------------------------------------

What im doing wrong here? It's looping that "Main new job" over and over again.

Win10/64bit



The lines
Code:
2016-02-16 10:32:59,984 INFO proxy # MAIN NEW_JOB
are just saying that the pool detected a new block, so your hashing needs to start over. Completely normal as the Ethereum block time is about 15 seconds.

At some point you should begin to see something like the below interspersed between all the MAIN NEW_JOB lines:
 
Code:
2016-02-16 17:34:22,930 INFO proxy # MAIN NEW_JOB
2016-02-16 17:34:32,384 INFO proxy # MAIN NEW_JOB
2016-02-16 17:34:40,211 INFO proxy # MAIN eth_submitWork by miner-05

2016-02-16 17:34:53,507 INFO proxy # MAIN NEW_JOB

2016-02-16 17:35:05,009 INFO proxy # MAIN NEW_JOB


Depending on your hashing speed this might take awhile, maybe even a minute or two between shares.

no need to run this stratum, most of the pool runs it now. if you noticed you have stratum at your bat file when setting up pool address. Grin

trying this proxy with dwarfpool, it connects and listens for miner, then i use genoil to connect using the settings here, it says can not find mining hardware....i have 6 rx580's, it does not detect them at all, can I use claymore to mine and run it through this proxy?

when i run the devices.bat file it picks up all 6 cards...but when I run the miner it picks up 0 wtf?

as most eth/exp pools support stratum, is there any point or benefit to using this proxy vs just connecting directly to the pool's stratum port using claymore's miner?  (i wouldnt think so, just checking for my own sanity, plus the fact that claymore in his readme even directly states "Using any proxies will reduce effective hashrate by at least 1%, so connect miner to Stratum pools directly. Using HTTP pools will reduce effective hashrate by at least 5%."

Thank you for the aweseom py tools that you have deveolped.

Is exetremly clear.

My question is, how is it related with the 3 different method of esm (Ethereum stratum mode) used by Claymore?

0 - eth-proxy mode
1 - qtminer mode
2 - miner-proxy mode

OK, got it too work like 1 time, but then I think I crashed it trying to change a setting to get my GPU working at 100%.

Here's my new batch file, turns out I was missing the "miner.exe file download all together.
So, do I launch it using my .bat command, below, or by clicking on the miner.exe using windows 10?

New ethminer.bat file:

Setx GPU_FORCE_64BIT_PTR 0
Setx GPU_MAX_HEAP_SIZE 100
Setx GPU_USE_SYNC_OBJECTS 1
SET GPU_SINGLE_ALLOC_PERCENT = 100
ethminer.exe --farm-recheck 300 -G -U -F http://192.168.1.198:8080

Or, should it be:

Setx GPU_FORCE_64BIT_PTR 0
Setx GPU_MAX_HEAP_SIZE 100
Setx GPU_USE_SYNC_OBJECTS 1
SET GPU_SINGLE_ALLOC_PERCENT = 100
#ethminer.exe -G -F http://127.0.0.1:8080/
#ethminer.exe --farm-recheck 300 -G -U -F http://192.168.1.198:8080

(yes there are no # signs in the actual file, but it kept deleting my address as suspicious for the 127 one)


Thanks so much for your time/help!

Anyone know why Claymore miner would throw a '287c / checkread timeout' error when connecting to this proxy?

Code:
12:46:48:412	287c	ETH: Stratum - connecting to '127.0.0.1' <127.0.0.1> port 8080
12:46:48:448 287c send: {"worker": "eth1.0", "jsonrpc": "2.0", "params": ["walletaddress", ""], "id": 2, "method": "eth_submitLogin"}

12:46:48:451 287c ETH: Stratum - Connected (127.0.0.1:8080)
12:46:48:506 1fc8 No pool specified for Decred! Ethereum-only mining mode is enabled

12:46:48:509 1fc8 ETHEREUM-ONLY MINING MODE ENABLED (-mode 1)

12:46:48:513 1fc8 ETH: eth-proxy stratum mode

...
12:47:19:788 287c ETH: Job timeout, disconnect, retry in 20 sec...

It will just continue to do that indefinitely.  I know I could just use Ethminer, but would like to understand why Claymore isn't working.  Anyone have any ideas?
