We have the server installed, configured and running but when attempting to connect miners we are receiving: "method 'subscribe' not found for service 'mining'"...

What did you installed exactly? Looks like you installed Stratum server without mining service. You need this one: https://github.com/slush0/stratum-mining

We have installed the server and the mining service, the pastebin output directly above your post is from the mining-proxy output with "-v" flag...

Hello,

We would like to implement Stratum protocol at minelitecoin.com and we are having a little trouble...

We have the server installed, configured and running but when attempting to connect miners we are receiving: "method 'subscribe' not found for service 'mining'"...

Any help would be greatly appreciated as we've spent hours going through Google and spent hours going through thousands of lines of code to try and figure this out to no avail...

Thank you in advance to anyone who can help us out and thank you Slush for putting in the work on the Stratum protocol to begin with...

Is their a chance of a feature to be added to status to in user part of how many shares have been mined total for user and paid and brake down...

Also question if share diff is higher do you earn double the amount more rewards Huh

Looks like this address doesn't belong to your instance of bitcoind, right?

Code:

Are you sure the port is OK? From the log above it looks like there's bitcoind sitting on this port.

I just released 1.5.1. It adds just a workaround for RPCminer, which doesn't work with targets produced by Stratum proxy. If you have RPCminer, please test the proxy with --old-target parameter and let me know if it fixed your issues!

Oh, Windows 7 Ultimate 64bit

Windows already implemented Stratum protocol? Cool! :-)

zvs, what software is on server side? These late and duplicated notifications looks like bug in server side implementation.

Oh, Windows 7 Ultimate 64bit

I was going to retest it later with minerd running 1 thread and affinity to 1 core with graphic cards at something like 0 intensity to see if that might have been causing it... (minerd wasn't maxed before, but it was still pretty heavy on the cpu)

First official release of cgminer that supports the new agreed upon resume protocol is out, 2.11.0

I just released Stratum proxy 1.5.0, which fixes many bugs from previous releases. All users are encouraged to update!

Intrinsically stratum is inherently faster and lower overhead than longpoll for both the server and the client. Minerd is fast. Cgminer is fast. Stratum is fast. On the other hand I can't speak for any other implementation at the other end.

so, earlier, I posted a query about stratum causing too much cpu load and jerkiness in computers that didnt have problem with longpolling. turning back on nagle seems to have solved that for the most part

but, i also noticed this

is minerd just really fast, is cgminer slow, or is stratum slow? one of them was 2s late

This looks good. Thanks for including the user-agent in there as well.

Note the session ID has changed between the initial subscription and the resume, BUT the extranonce1 has remained the same. This tells the miner it can (re)submit shares before the disconnection.

If the resume fails, how should the server respond? Give an error, or just a new extranonce1?

If the old connection is still there, I guess the server could disconnect it. That means the session ID must be hard to guess so you can't disconnect other people. You must also be very sure that you don't give out the same session ID twice, or you'll have two workers disconnecting each other all day.

It's safer to never resume a connection that still appears up to the server. But I wonder how often it will happen that a client tries to resume before the server discovers that the old connection is dead.

Letting both connections stay seems like a bad idea. They'd both be doing the same hashes in the unlikely event that they both keep hashing.

I think submitting a new extranonce1 is all that is required. We should view the sessionid submission as a hint only and let the pool decide what to do. You will indeed need unique session IDs for this support to work. When luke-Jr tested it, he found that the old connection was not actually detached before I was requesting a new one with the sessionID. This is not surprising given how difficult it can be to tell that a raw socket is actually broken or not. I suspect that dropping the first connection there is the answer.

Ok for those not watching the discussion on #stratum on IRC, I believe we have a final protocol for mining resume which should not break any clients or pools.

It was decided that the parameters could include both the user agent and the session ID as the first and second parameters. If this fails cgminer/other clients should resort to sending blank set of parameters as previously.

The session Id, it was decided, would be encoded along with the notification message "mining.notify" as a member of the 3 deep array parameters returned for "result" by the pool.

See the following for an example of an initial connect followed by a reconnect.

Code:

 [2013-02-25 10:30:58] SEND: {"id": 0, "method": "mining.subscribe", "params": ["cgminer/2.10.5"]}
 [2013-02-25 10:30:58] RECVD: {"result": [[["mining.notify", "02000000b507a8fd1ea2b7d9cdec867086f6935228aba1540154f83930377ea5a2e37108"], ["mining.set_difficulty", "02000000b507a8fd1ea2b7d9cdec867086f6935228aba1540154f83930377ea5a2e371082"]], "02000000", 4], "id": 0, "error": null}

 [2013-02-25 10:33:00] Pool 0 confirmed mining.subscribe with extranonce1 02000000 extran2size 4

Note the session ID has changed between the initial subscription and the resume, BUT the extranonce1 has remained the same. This tells the miner it can (re)submit shares before the disconnection.

Hopefully we will not need to revise this any further.
