Free cloud-based stratum proxy for Slush & BTCGuild (beta)

[shogunmark]

Very interesting! Thanks for the replies! I definitely wasnt setting out to try any real mining with mobile devices, just wanted play around with it. Thank you for the information!

Ok, I now have 4 new proxies open (the old ones are still there for now):


eastcoastbtc.cloudapp.net
westcoastbtc.cloudapp.net
westeuropebtc.cloudapp.net
northeuropebtc.cloudapp.net

They're located in Virginia, Washington, France and Spain (I think - I can't really tell for sure, but it's supposed to be East US, West US, West EU, North EU).


Pick the server that are closest to you as primary, and some other one as backup. The servers all support both BTC Guild & Slush. To select which pool you want, specify an appropriate port:

BTC Guild: 8884, 8885, 8886
Slush: 8900, 8901, 8902

Please toss a dice or something otherwise random to see which individual port to pick. Or if you have more than one blade, spread them across ports.


e.g. (for a BTCGuild setup):

Ports: 8884,8884
Server addresses: westeuropebtc.cloudapp.net,northeuropebtc.cloudapp.net
user:pass: myname_worker:x,myname_worker:x


PS: I'm now also using 5 block erupters to keep cycling through all of these ports to make sure they're alive. If one of them goes down I'll get a timeout message from BTC Guild. Finally Block Erupters are useful for something

+1 for doing this!         

brilliant idea!

could you do one for 50btc?  

much cheaper fees than btcguild

[eleuthria]

could you do one 50btc? 

much cheaper fees than btcguild

PPLNS on BTC Guild averages higher than 50BTC due to NMC and TxFees.

i'll give that a try...

I would, but I can't ever connect to 50BTC. I've come to believe 50BTC is a myth .

That's what drove me to Eligius in the first place. Also PPS, but with a 0% pool fee.


Seriously though, they just have very bad instructions on their web site in terms of which servers support which ports. If you can let me know the address & port of a 50BTC server that accepts stratum, I'll set up a proxy for you.

pool.50btc.com:8332    is what my block erupters mine on....      its stratum



this is what ive found online...


Hosts:
pool.50btc.com:8332 - main host
pool2.50btc.com:8332 - backup host
If you want to specify a pull-server to connect to, you can choose from:
pool-de.50btc.com:8332 - Host is located in Germany
pool-us.50btc.com:8332 - Host is located in the USA
pool-ru.50btc.com:8332 - Host is located in Russia
Port 80 mining (Long-Polling port is 443):
pool80.50btc.com
All pool-servers, except pool 80, have Stratum protocol support. All suitable miners would be automatically redirected to port 3333 on connection.


wish the Blade was as simple to use as the usb erupters

How is your individual worker name & password set up?

I have a worker that's displayed on the 50BTC site ( dbbitblade1 ). However, if I use it the proxy doesn't connect at all, and individual bfgminer using usb block erupters just states:

[2013-09-26 16:25:46] Probing for an alive pool
[2013-09-26 16:25:54] Pool 0 slow/down or URL or credentials invalid

This is with pool.50btc.com:8332

What is the exact bfgminer command line you're using for your USB erupters?

[xzempt]

i use cgminer...


http://pool.50btc.com:8332     for the server



username :emailaddress@.com
pw: x


i just launch cgminer-nogpu.exe    and input the server    hit enter,   workername  hit enter       x hit enter,       


since im not mining with gpus,   it is just easier than making a .bat file  imo

1.) East Coast, US

2.) I hope that isn't me... Apparently Slush's pool very recently removed the ability to switch difficulty manually. They said stratum should do it automatically. When I was using the original stratum proxy my difficulty was automatically switched to 8. So I take it the setting doesn't stay that way...

*Update*

[11:40] <slush> if there's such "need"to manually define miner difficulty, then it is a bug of miner or some other part of mining equipment. But as pool is using vardiff now, user-defined difficulty has no sense anymore

My miners are 2 days old and were working at 110% efficiency up until the slush proxy messed up. So I know it isn't my miners.

Ok, thanks. I'm generally on BTCGuild. I just tried Slush, and it seems to work fine for me. (It's not just a "well, it works fine for me under controlled circumstances when stars line up" - these servers are over the Internet even for me).

Couple of more questions:
a) What is your internet service speed?
b) What Operating System are you running?

Meanwhile, I'll bring up 2 more servers - US East Coast and Western Europe (since slush is in Amsterdam). It will take me a few hours. I'll appreciate if you can try it out after that. Will post here (and PM you) when they're ready.

Sorry for the late reply.

a.)Cable 10megabit up/5 down highest cable package in my area
b)The PC I'm using for general things(gaming, forum posting, etc) is windows 7. The netbook that I run proxies and do other bitcoin related things on is Linux. Debian Mint

Ok, so I tried your new servers. Here are my results:
1. Couldn't get anything going on any of the BTCguild ports with either west or east coast USA. My blade wouldn't start running and it would just flip between east and west. I tried all of the ports, and they came back with the same results.

2. Slush ports work! The blade is running on westcoast USA 8900 and it's almost at its optimum levels of 10gh. I'm going to keep my eye on it to see if there are any more hick ups. The only thing that I notice is slush's pool worker stats don't show the same mh as the blade is pulling. It seems to be slowly going up however, is this normal?

I'll keep my fingers crossed for there to be no problems. Unfortunately I can't seem to get a personal proxy going off my own network so in a way I am now relying on your services to keep my blades up and running. I really appreciate what your doing and I'll let you know if I find anything else out about my blade running on your network.

how do i edit the pool inside mining_proxy.exe
 

[eleuthria]

how do i edit the pool inside mining_proxy.exe
 

Run it with '-o <server> -p <port>'.  On Windows, this means either launching the proxy via command line with those arguments, or creating a shortcut and adding those arguments to the target.

[xzempt]

ty,    how do i specify which port to use on the local computer?   Ive added stratum.btcguild.com:3333    and got miningproxy.exe going,    so when i point my miner to 192.168.1.106  for the computer its running on.... which port would i specify?

By default, the stratum proxy listens for your miners on port 8332.  You can change this using '-gp <port>'.

did something happen to the cloud stratum proxies?   

[dbbit]

No, they're up. I'm connected to them right now.

Which ones are you trying?

Are you perhaps trying to connect to BTCGuild? Keep in mind there is a DDOS attack against BTCGuild right now.

[xzempt]

yes was connecting to btcguild,   looking at the network hashrate it appears they are still being attacked.... 


mining ppcoins thru d7.lt getwork for the time being.....

[Yinero]

So the first day my blade was running on here it was pulling 10 - 11gh. THe past couple days it's only been pulling 4gh and been bouncing between west and east coat US for slush's pool.

I'm really starting to dislike mining_proxy.exe....

I'm connected to the exact same 2 servers, and have been getting 12gh for 5 days straight. The CPU usage for those servers over the last week have both been below 18%.

Anyway, could you try connect to either of:

slush1.cloudapp.net
slush2.cloudapp.net

Port: 8884, 8885 or 8886
