Right, a question without an obvious answer. The point of the stratum header on the regular getwork pools is to redirect them to a better protocol pool. The fact that btcg redirects all pools to the same one stratum pool is more a sign of early days with btcg having only one stratum server. I'm guessing with time btcg will have 3 stratum servers to match its 3 getwork servers.

I'll be updating the BTC Guild getwork-based backends to use different X-Stratum redirects this week, now that we're starting to see integration in the most widely used miner.

Thank you!

Leakage question...

I'm mining with cgminer with 2 workers one on ubuntu 12 and the other on windows 7 and I see the same odd behavior on both...

I've got 2 pools configured as failover (I did not choose load balance or rotate or anything like that), and about 80% of the time I see "leakage" over to my secondary pool! Weird.

I'm mining at 4500Mh/s at bitminter (2 workers) with no overt pool switching--either automatically or by my choice. I keep it steadily pointed at bitminter....But most of the time I'm seeing about 14Mh/s coming from my 2 workers to Mtred--my secondary pool!

I see no indication of this in either worker's console--they both look solidly connected to bitminter. I don't have any connection errors or slow communication or anything. Everything looks great except there's 14Mh/s leakage to Mtred from both workers.

What gives?? Any ideas?

Got it Thanks!

"Q: Work keeps going to my backup pool even though my primary pool hasn't
failed?
A: Cgminer checks for conditions where the primary pool is lagging and will
pass some work to the backup servers under those conditions. The reason for
doing this is to try its absolute best to keep the GPUs working on something
useful and not risk idle periods. You can disable this behaviour with the
option --failover-only."

I've been over that readme.txt many times getting things going and I've really appreciated all your work that went into it--so thanks much for that--it's all working very smoothly.

Stratum update

The code has been in testing for a while now, and numerous issues have been ironed out. I've been mining with it for a few days in a mixture of regular pools + stratum pools and things seem to working out okay. I've just managed to get it building and working on windows and have created the first binary for people to start testing it. It's still not mature enough for a full release, but at some stage I need people to start testing it so I can sort out issues as they arise.

If you're on linux, and can use git, checkout the stratum branch and build from that.
git pull -a && git checkout stratum

For those on windows, here is a test binary.
http://ck.kolivas.org/apps/cgminer/temp/cgminer.exe

Just drop  it into your existing 2.7.6 directory. It will still read version 2.7.6, but don't let that fool you. For stratum to be active, you need - of course - to mine on one of the 2 pools that currently support it: slush's pool and btcguild . The way I've set up the code, you shouldn't need to do anything special to mine stratum, just use your regular settings (or you can plug in the stratum info directly if you're so inclined). The advantages to the miner should be far far less network communications with less network delays which should also translate into less rejects. Of course the real advantage is to the pools and for the ability to scale to much higher hashrates with the advent of ASICs.

Lots has been written about it here (though it may be rather confusing):
https://bitcointalk.org/index.php?topic=108533.0

EDIT: There is NO proxy support whatsoever for stratum at this stage.
Updated the codebase, and uploaded another windows test binary. It now uses curl for its sockets which allows at least socks proxies to work. http proxies are tricky since you'd need a proxy with special permissions to allow such an arbitrary connection.

 [2012-10-05 01:35:30] Failed to recv sock in recv_line                   

no error in the response (RECVD) this time, but still get the repeating "Failed to recv sock in recv_line"
Sent message is still corrupted, though job_id, nonce2 and ntime are all intact earlier on. Can you git pull and try again please.
