OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

Hi, I've finally given up on trying to find out what I'm doing wrong with connecting to 50btc. Here's my cgminer.conf file. It's an exact copy of another one that works fine, just with btcoxygen in stead of 50btc. Running on Raspbian with USB Erupters

Code:

{
"pools" : [
        {
                "url" : "mint.bitminter.com:8332",
                "user" : "xxx",
                "pass" : "xxx"
        },


        {
                "url" : "stratum.bitcoin.cz:3333",
                "user" : "xxx",
                "pass" : "xxx"
        },

        {
                "url" : "de.50btc.com:8332",
                "user" : "[email protected]_myworker",
                "pass" : "xxx*"
        }


]
,
        "balance" : true,
        "api-listen" : true,
        "api-port" : "4028",
        "expiry" : "120",
        "log" : "5",
        "no-pool-disable" : true,
        "queue" : "2",
        "scan-time" : "60",
        "worktime" : true,
        "shares" : "0",
        "kernel-path" : "/usr/local/bin",
        "api-allow" : "0/0",
        "icarus-options" : "115200:1:1",
        "icarus-timing" : "3.0=100"
}

for the url I've tried each of these: de.50btc.com:8332, pool.50btc.com:8332, http://pool.50btc.com:8332
and for the user: [email protected]_myworker, myworker, [email protected]

but every time I try to run cgminer:
./cgminer -S /dev/ttyUSB0 -S /dev/ttyUSB1 -S /dev/ttyUSB2 -S /dev/ttyUSB3  -S /dev/ttyUSB4 -S /dev/ttyUSB5 -S /dev/ttyUSB6 -S /dev/ttyUSB7 -S /dev/ttyUSB8 -S /dev/ttyUSB9 --config /home/pi/cgminer-3.1.1/cgminer.conf

 I just get the same error:
 [2013-07-14 15:33:16] ./cgminer: --config: JSON decode of file '/home/pi/cgminer-3.1.1/cgminer.conf' failed
 '}' expected near '*'


I hope someone can help. Thanks

Your password is confusing the conf file reader with the asterisk (*) there. Change your password to something without an asterisk or learn how to escape the asterisk in a json compatible way.

./cgminer -S /dev/ttyUSB0 -S /dev/ttyUSB1 -S /dev/ttyUSB2 -S /dev/ttyUSB3  -S /dev/ttyUSB4 -S /dev/ttyUSB5 -S /dev/ttyUSB6 -S /dev/ttyUSB7 -S /dev/ttyUSB8 -S /dev/ttyUSB9 --config /home/pi/cgminer-3.1.1/cgminer.conf

unrelated to your issue, but instead of those -S arguments, adding the following to the config will do the same thing, just neater...

Code:

"scan-serial": [
    "/dev/ttyUSB0",
    "/dev/ttyUSB1",
    "/dev/ttyUSB2",
    "/dev/ttyUSB3",
    "/dev/ttyUSB4",

    "/dev/ttyUSB8",
    "/dev/ttyUSB9"

That's just a hasty typo. I meant to just fill it in with xxxx. My password isn't really xxx*. Although, the * is actually the last character on the password. That was lucky!   

Maybe this explains my having a similar problem with Btcmp, where the password includes ?#[ characters, and Eclipse if fine with no special characters. 

@turtle83 thanks for that. Must neater in deed

I try enable onboard GPU for Display output, so my HD4670 have 100% available resources, basically become Dedicated OpenCL. but...

when enable onboard GPU, AMD OpenCL become unavailable... =(

Did you try putting a monitor or dummy plug on it?

Yes I did, even try 2 monitor in different GPU's, just AMD GPU dont have display, (since I set BIOS to initialize onboard GPU first)

I think the more relevant question is why on earth would you mine on that hardware.
You will get more BTC if you just simply buy BTC.

With the FASTEST 4600 GPU you can buy, it can only do 40MH/s and that will at current difficulty take 1300 days mining to make 1BTC
Of course it will never actually make 1BTC due to difficulty rising.
i.e. you are wasting everyone's time asking.

The problem is 99% likely to be your choice of drivers and SDK ... so spend a few hours getting that right ... and those few hours spent on it is probably worth more than the card will make mining for 10 years.

I have another system run, 
This old system can not be waste or throwing, so I make this old system to working, I testing the possibility, this old hardware can not do Dedicated OpenCL.

Simple question, I hope. If I knew my way around *nix/BSD I might not have to ask it.

Running cgminer to mine litecoins. Upon launch it tells me no GPUs can be detected. The display tells me that new blocks are being detected, but the miner is sitting at zero hashes per second.

I suspect that somewhere once upon a time I did something to disable GPU mining.

Is there a flag or something I can include when launching cgminer that will enable it to find the GPUs and use them?

(I've done a search through the thread using search terms, but didn't come up with anything helpful--I hope I'm not asking a FAQ, and I apologize if I am!)

Many thanks in advance for any suggestions!

[Joshwaa]

What GPU is in the system?  Also have you tried the GPU-README or the SCRYPT-README?

But the more important question ...

I not understand, Yozora? Mikazuki Yozora?

Found this in the GPU-README (thanks for pointing that out to me--I overlooked it the first time I scanned down the list of files at github).

Q: Cgminer cannot see any of my GPUs even though I have configured them all
to be enabled and installed OpenCL (+/- Xorg is running and the DISPLAY
variable is exported on linux)?
A: Check the output of 'cgminer -n', it will list what OpenCL devices your
installed SDK recognises. If it lists none, you have a problem with your
version or installation of the SDK.

It appears I need to birddog the SDK.

Thanks for pointing me in the right direction!

[Joshwaa]

Thank Con and Kano, not me. However your welcome all the same.

I'm solo mining on Pool 0.  I started getting a lot of "not providing work fast enough" errors.  Any idea what's wrong or how this could be fixed?

Code:

Edit: initially I had thought it a slow network connection so I made sure the appropriate ports were open.  I have about 20 connections to the network and ping < 50ms.

Are you using the Getwork protocol to your solo pool?

What hash rate is your mining hardware?

[kentt]

I'm mining YAC at 300khps.  Should be getting ~16 blocks per day and I was before.
What do you mean "are you using getwork".  I'm guessing if I don't know the answer is no?

Typo?

[kentt]

Not a typo.

Why would I be needing to run as root even after changing /dev/ttyUSB0 to 777?

cgminer no longer uses ttyUSB0 so you're changing permissions on an interface cgminer doesn't use. See the relevant readme instead (FPGA-README or ASIC-README).
