I should first have this proxy runned or it can work normaly without it ?
since no much documenation about mining pool(for proxy yes i tryed proxy for other pool and it works) i dont understand how stratum mining pool works, i downloaded it and i only have config file, dont understand even how to turn it on, so i would like to ask here?

Today I switched my unsupported Ztex BTCMiner to use local Stratum proxy on BitMinter mining pool. Everything is working flawless. Now I can see, how often my miner is asking for more work and how often reporting shares (Diff 1 share theoretically is found every 0.5sec; thanks to Stratum and var-diff now I have Diff 8 shares).
From now on everything is in my local network, saving bandwidth, resources and decreasing amount of stale shares.
Marek, thank you for designing and supporting such a great protocol Smiley

I tried to compile
Code:
~/stratum-mining-proxy/midstatec$ make
gcc -march=native -Wall -funroll-all-loops -O3 -fstrict-aliasing -Wall -std=c99 -I/usr/include/python2.7  midstatemodule.c -o test -Wl,-O1 -Wl,--as-needed -lpython2.7
midstatemodule.c:5:20: error: Python.h: No such file or directory
midstatemodule.c:96: error: expected â=â, â,â, â;â, âasmâ or â__attribute__â before â*â token
midstatemodule.c:138: error: array type has incomplete element type
midstatemodule.c:139: error: âmidstate_helperâ undeclared here (not in a function)
midstatemodule.c:139: error: âMETH_Oâ undeclared here (not in a function)
midstatemodule.c:164: error: expected â=â, â,â, â;â, âasmâ or â__attribute__â before âinitmidstateâ
make: *** [test] Error 1
Code:
$ python --version
Python 2.6.6
Code:
$ apt-cache policy python
python:
  Installed: 2.6.6-3+squeeze7
  Candidate: 2.6.6-3+squeeze7
Is python2.7 really needed? On my Debian I have version 2.6. I changed 2 lines in Makefile:
Code:
CFLAGS = -march=native -Wall -funroll-all-loops -O3 -fstrict-aliasing -Wall -std=c99 -I/usr/include/python2.6
LDFLAGS = -Wl,-O1 -Wl,--as-needed -lpython2.6
And it compiled without problems Smiley As you see here:
Code:
2012-12-18 20:58:50,564 INFO proxy jobs.<module> # Using C extension for midstate speedup. Good!
2012-12-18 20:58:50,872 WARNING proxy mining_proxy.main # Stratum proxy version: 1.3.0
Could python version be automatically detected?

I made this to fill my needs, but auto-detecting would be nice. Patches are welcome :-)

Note that the python midstate module is from http://gitorious.org/midstate/midstate
It would be nice if fixes/improvements were submitted to the main codebase rather than just a fork.

Josh,

If you are just looking to connect to a pool with stratum then just use cgminer (It supports it internally, so no extra steps.)

If you are looking to run your own solo pool:
Slush's stratum pool is kept very simple and is for pool software writers. I've forked it and made it a little more suitable for fulltime use (added things like db support, stats page, basic install instructions, etc...) it's at: https://github.com/generalfault/stratum-mining

If you are looking to connect non-stratum aware miners to a stratum pool then use the proxy.


Did I help you? Tiny Donations always welcome : 15Zk7DoFYJ7hESpZzmix1WLkomTMGW81c2

Yes, the original version is for python3 only. Unfortunately source requires some changes to make it compatible with python2x and making patch for upstream is out of my C skills.

OS is OpenWrt
i tried git clone and the tarball
i installed bzip2

any ideas?

update:
downloaded twisted-12.2.0 and tried to install it

so i guess that means no stratum without gcc?

You need to install python-dev, which will install gcc as well. It is mentioned in installation howto.

It just means that client is talking to the server with HTTP protocol, instead of Stratum.

there is no python-dev for openWrt and i will not cross compile anything, so my fpga will keep mining with getwork :-/

should i ever get my asic i will use the raspberry, i guess it shouldn't be a problem running stratum on it

Didn't someone have instructions to actually compile CGMiner  to run on openWRT?
It would both run stratum and usb devices solving your probem if I am right.

Yesterday I had what seemed to be an unlimited loop of the following in my (proxy) log. Restart solved the issue.

Code:

As slush said above, your client is talking http to a stratum/json port. you most likly have the pool specified on your client as:
http://yourhost.somewhere:3333
and it should be:
stratum+tcp://yourhost.somewhere:3333

and stratum doesn't understand http (nor should it.)

Your config.py is not complete (a setting is missing.) Please read the INSTALL file and follow the instructions. (Step 3 in particular is what you didn't do ... or messed up)
