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.)

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

Code:

---  ---
  File "/usr/local/lib/python2.7/dist-packages/Twisted-12.2.0-py2.7-linux-x86_64.egg/twisted/internet/defer.py", line 134, in maybeDeferred
    result = f(*args, **kw)
  File "/home/worker/stratum-mining-proxy/mining_libs/worker_registry.py", line 37, in authorize
    d = self.f.rpc('mining.authorize', [worker_name, password])
  File "/usr/local/lib/python2.7/dist-packages/stratum-0.2.11-py2.7.egg/stratum/socket_transport.py", line 89, in rpc
    raise custom_exceptions.TransportException("Not connected")
stratum.custom_exceptions.TransportException: Not connected
Unhandled error in Deferred:

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.

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

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

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

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?

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.

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.

For stratum mining pool i dont understant one think
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?

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.

Could python version be automatically detected?

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

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

As you see here:

Code:

2012-12-18 20:58:50,564 INFO proxy jobs. # 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?

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

No worries, I commented it out in the source and restarted the proxy already.
