[ANN] Stratum mining protocol - ASIC ready

[Luke-Jr]

Hi guys

I'm trying to setup a simple http request to stratum mining pool in c#. I'm getting this error: "Underlaying connection was closed."

Code:

string json = "{\"method\": \"getblocktemplate\", \"params\": [], \"id\": \"0\"}";
WebClient w = new WebClient();
w.Credentials = new NetworkCredential("user", "pass");
w.Headers.Add("Content-type", "application/stratum");
j = wc.UploadString("http://blabla.com:3333", json);

Please help

This thread is for the stratum mining protocol, but you seem to be trying to use GBT (with the wrong Content-type, and apparently connecting to a stratum host...)
GBT and stratum are not compatible.

So... I have stratum mining proxy up and running and it looks like everything is ok... but when I throw a miner at it..

All shares are rejected - Low Difficulty

Example:

 [2014-04-03 16:02:21] Rejected 1423c153 Diff 3.25K/256 GSD 9  ((23, u'Low difficulty share'

You may notice I am using Gridseed Fork of cgminer....Maybe compatibility Issue?  Its 3.7.2....

100% of the shares are rejected.

Ideas?

Stratum Set Up:

./mining_proxy.py -o ltc.ghash.io -p 3333 -cu myname.1 -cp x -sh 127.0.0.1 -sp 3333 -oh 127.0.0.1 -gp 8334 -nm -rt -st

Mining Side:

sudo ./cgminer  -o 127.0.0.1:8334 -u myname.1 -p x --gridseed-options=baud=115200,freq=850,chips=5

Difficulty ti properly adjusted at the pool and can me mined without the proxy.

###EDIT - does "-rt" allow a difficulty setting?

[DrHaribo]

Any documentation for these Stratum protocol extensions?

client.reconnect
client.add_peers
client.show_message
mining.get_hashrate
mining.get_temperature

Are there any other interesting extensions in use?

Reconnect and message are implemented, but I'm pretty sure the others aren't implemented anywhere on either pool or miner side. As for documentation, yes it's a shame we never got a full document out somewhere and the links from slush's pool are now broken amplifying the problem. That means this thread is the closest we'll come to official documentation unless someone goes through and collates it all into a nice document. That's why I pinned this thread.

[Luke-Jr]

Anyone up for writing a BIP draft? Slush finally had numbers assigned a while ago, but apparently he's been too busy to actually write the specs...

I've created a new forum thread that tries to collate all relevant information in one place:

I am trying to connect asicminer BE cubes by miner_proxy with p2pool by stratum.

Firstly, I am solved issue for geting job form p2pool to proxy by stratum, with patching protocol.py in stratum, by adding MAX_LENGTH = 16384000.
Now job received by proxy, but cubes can not get works by getwork.

If I run miner_proxy.py by default, it work normally.

[blackvoice]

ckolivas, since you made cgminer, I am sure you will know to answer this question about stratum protocol; is it possible to turn stratum client into a pool, so that incoming stratum work is further divided into work for other clients. I am building a proxy that sits between pool and multiple instances of cgminer, so that the pool "thinks" it is in fact only one miner running. I know there is existing implementation that does stratum->getwork, but why should I go that heavy load path. I need to develop something light and fast, doing it in C and every cycle is important.

I think the answer maybe "yes"

My cousin is behind a firewall (sky) and cant open port 3333 due to his sky router not working correctly however he does know some ports that are open and we have tried one of these. However we are having some issues with it. Every share he submits get rejected with the below. when we tried a closed port we got nothing so the work is deffo getting through.

I can see the shares on the proxy, but just dud shares, does anyone have any idea?

2014-05-06 11:13:53,167 INFO proxy stratum_listener.submit # [120ms] Share from 'catinahat.1' REJECTED: (-2, u"Job 'b59d' not found", None)

he is using sgminer because he gets the best hashrate out of it. Is stratum proxy just too old now?

I would pay for it if it's coded in Mono C#.

Hi,

I have just released a Java (works on Windows/Linux/Mac...) stratum proxy implementation (only a stratum proxy, it does not support getwork). Since I am a scrypt miner, I have not tested it with SHA-256 but it should work fine. So, if some of you want to test it...

Here are some links:

Can someone help me I am having a hard time getting my cubes to connnect to stratum and mine



This is my settings for the cube miner

I have a batch file that opens the stratum proxy using this code

cd C:\Program Files (x86)\Proxy
mining_proxy.exe -o us1.ghash.io -p 3333

and I am getting these errors

Don't know if you have solved this by now, but here is my two-cents of info.

It's been a while since I messed with one of these, but I think the problem is that you need to specify a getworks port on the proxy for the cubes to connect correctly.  They are "getwork-based" miners.

Use:

mining_proxy.exe -o us1.ghash.io -p 3333 -gp 8332

Then in the cube configuration, set "Pool ports" to  8332,8332 instead of the 3333,3333 that you are currently using. Then select the "Update/Restart" tab to save and restart the cube.



Once that is tested and the cube is working, I would add a few more arguments that will help your cube work better.

Try this:

mining_proxy.exe -nm -q -rt -o us1.ghash.io -p 3333 -gp 8332


These arguments are:

-nm, --no-midstate    Don't compute midstate for getwork. This has outstanding performance boost with the blades/cubes.

-q, --quiet           Make output more quiet

-rt, --real-target    Propagate >diff1 target to getwork miners. Some miners work incorrectly with higher difficulty.

i am looking for some help with p2pool and the stratum server. i am having problems getting the latency to stay lower. i have a very good internet connection so i dont see why that would hurt it at all. 250 mbps down 15 up. the stratum proxy p2pool and bitcoind are all on the same computer. i7 6 core intel overclocked  watercooled and 32gb of ram. so there should also be no problem with the cpu load or ram load.
all of the ports that needed to be forwarded are. and i am still having no luck. after an hour or a few hours. the stratum proxy seems to lag like crazy to bitcoind

[infernoman]

i also cannot seem to get the proxy to connect directly to my wallet so that i am able to solo mine. and i am having alot of problems with the p2pool still so i would like to try mining directly to the wallet.

Few questions as I'm doing some heavy work with a custom stratum pool.

First off, is mining.set_extranonce being officially supported? If so, is cgminer going to be officially implementing this? I know bfgminer does currently support it.

cgminer doesn't support most things, just the minimum necessity for specific use cases.
Generally, you shouldn't need mining.set_extranonce, though.

I do, however, require support for set_extranonce. I'll do my own build of cgminer then. Just a pain to get users to use it rather than what they already have. Thanks for the reply.

Could just tell them to upgrade to BFGMiner...

Likely will, do you plan on supporting the new titans and vaultbreakers? Not sure how mining software goes about supporting new hardware. I will need support for very high mhs scrypt machines as soon as they ship.
