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)

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.

If you 'roll' on over to FreeNode #cgminer it's usually easy to sort out where the problem is.

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...

... as per API-README - you say in cgminer what IP addresses are allowed to access cgminer.
Then in miner.php you say the IP:port:randomshortname of the cgminer

Yeah, I forgot to mention that I did that. I set the allowed addresses in the config file, and as you saw below that statement, I added it to miner.php.

... as per the README FAQ ... it means sockets are either disabled on not installed in your PHP
There is a link in the FAQ.

That's the part I can't figure out.

Code:

Q: I run PHP on windows to access the API with the example miner.php. Why does
it fail when php is installed properly but I only get errors about Sockets not
working in the logs?
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.

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

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

I immediately stopped the 2.8.4 and restarted 2.7.5 and i have no stale shares at all yet. Soemthing is definetly up

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.

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.

... as per API-README - you say in cgminer what IP addresses are allowed to access cgminer.
Then in miner.php you say the IP:port:randomshortname of the cgminer

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.

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.

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.

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

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."

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?

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.
