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

Even better would be a custom debug build running in gdb but I doubt any of you are up for that   I'm trying that on my laptop which is the only thing that has windows. Hopefully I don't fry it in the process, but at 10MH/s I also doubt it will recreate the problem.

Sigh. I wish it were only linux...

How do you do that? I tried something a while back but didn't get it working.

What I want to do is run under gdb, save the environment when it crashes, then continue running so that it's not sitting all day locked up.

When you build it, build it without optimisations in the CFLAGS and with the -g option, i.e. CFLAGS="-g -Wall -W" only. Then
gdb cgminer
run [usual cgminer parameters] -T
Running it with -T is a good idea cause gdb spews out other information and corrupts the display when you're using the curses display.

Here's a debug build in case someone is willing to try it:
http://ck.kolivas.org/apps/cgminer/temp/cgminer.exe

Meanwhile my laptop continues to fry itself but has not crashed with the windows binary. It's probably too slow to even reproduce the problem.

Just upgrade3d from 2.7.x to 2.8.x   

Can someone please provide a plain english explination of the "Diff" data in the HW mining lines? eg Diff: 100/25

Thanks in advance

The first number is the difficulty of the share, the second number is the minimum difficulty accepted by the pool. If the difficulty of the share is higher than the current Bitcoin network difficulty, you found a block.

[Frizz23]

OK - so here the last lines before my cgminer crashed (v2.8.4 on Win7x64).

Note: I lost Internet connection for a few hours - maybe that caused the crash?

Not exactly revealing of anything :\ Was there a relationship time-wise with the internet connection going down/up and the crash time?

[sharky112065]

It is right in the README file included with Cgminer...

"The 2 diff values are the actual difficulty target that share reached followed by the difficulty target the pool is currently asking for."

[-ck]

Ok so what I've done to try and help debug this is I've built a special windows build of cgminer that uses a special dll to help print out the backtrace if it crashes that should help me find where it's crashing.

To use it, grab the following 2 files:
http://ck.kolivas.org/apps/cgminer/temp/cgminer.exe
http://ck.kolivas.org/apps/cgminer/temp/backtrace.dll

and put them into a regular 2.8.4 windows directory. Start it as you normally would, but with the -T option otherwise the display gets corrupted when the program exits, and if it crashes while mining stratum, send me what is output when it crashes please!

Meh doesn't seem to do what it's advertised as doing... sigh need to think of another strategy.

[Toresh]

I am running the debug cgminer 2.8.4 on my Win7 machine for about a day now without any problems. It is connected to Slush's Pool via stratum and it has an Nvidia card so it's about 110Mh/s and it it also used for games.

[mezzomix]

Put the stratum URL in without any prefix in the config file.

Without the prefix:

Code:

...
"url" : "api-stratum.bitcoin.cz:3333",
...
"url" : "stratum.btcguild.com:9332",

I get:

Code:

0: Enabled Alive Priority 0: http://api-stratum.bitcoin.cz:3333 ...
1: Enabled Alive Priority 1: http://stratum.btcguild.com:9332 ...

So this seems to work now. Only the http:// prefix in the user interface is misleading.

What are the limitations of miner.php when used on a webhost (such as bluehost, hostgator, etc.) ? [I am familiar with php btw]

I was thinking that first of all, I have to set api-allow to the host's shared IP to my config file, or allow all.

2nd: I have to forward public port 4028 on my router to my rig's internal ip address and private port. (in this case it's the same port as the public one)

3rd: I have to instruct miner.php to look at my public IP address:port.
 line 45:

$rigs = array('<my ip>:4028:QUADMINER');

4th:

5th: PROFIT!

I am having an error...
Error getting device list: ERR: socket connect(<my ip>,4028) failed 'Operation now in progress'

I notice that i am getting many more rejected shares now that im using 2.8.4 compared to 2.7.5. I usualy get about 10 rejected shares per 20 000 accepted shares. Now with 2.8.4 ive gotten 200

A: http://us.php.net/manual/en/sockets.installation.php

 

I am not running PHP on windows. I have bluehost, and they use apache.  Visiting that link doesn't help me. I don't know what this means, or how to do it:

Code:

The socket functions described here are part of an extension to PHP which must be enabled at compile time by giving the --enable-sockets option to configure. 

There's a user note on that page that says you need to uncomment the line that reads
;extension=php_sockets.dll (by removing the semi colon), or if it's not there, to add it.  I don't know where to add it, so I added it to the end.  Still having same error.

So, AS PER THE README FAQ, I am not running php on windows to access the API, so I didn't think it applied.

This is not a priority because I only want to monitor one rig, and I can use CMD.exe to run API calls. (it's just that it doesn't like when I use the pipe, for some reason)

Thanks for your help. Anyone got it working on bluehost? LMK.

I will continue to interface with the google for now.

Nothing's changed in management therein, so I can only assume it's coincidence and pool related.

Did you move to stratum with 2.8.4?

EDIT: To explain why I ask that, cgminer + stratum gets notification of block changes much faster than ever so it should reduce the number of stales. On the other hand, I have noticed that slush uses that as an excuse to ignore any shares that are returned from the previous block immediately once it has stratum notified you of the new block saying job not recognised, so to me it looks like stales on slush went up, not down, despite the potential advantages. I'm not sure how btcguild fares there.

Well if sockets are actually working (the link there is about how to enable them when they aren't working) then it's a problem with the socket connecting to the target.

So it's a firewall/port forwarding problem if sockets are installed properly and enabled in PHP
(they are on by default usually in linux, but not always in windows)

How to enter multiple pools from the command line?

Here's my shortcut that launches it upon startup (win7):
C:\cgminer\cgminer.exe -o http://pool.bitclockers.com:8332 -u MyPoolUsername1 -p MyPoolPassword1 -o http://mtred.com:8337 -u MyPoolUsername2 -p MyPoolPassword2 --load-balance

Hope that helps...

That's what I figured.  I will update this thread if I ever find a solution. I am trying out some experiments from the php.net website.
