CKPOOL - Open source pool/proxy/passthrough/redirector/library in c for Linux

@ck are the M* tags considered more stable than master? or S* tags? are there still version numbers for stable releases?

Tagged versions are considered stable for use indeed. The S tags were a mistake, the M tags stand for "milestone" releases. Having said that, the current git master is currently stable but that can change at any time. The version numbers are almost an afterthought.

great so use M tags for stability when in doubt

[chiguireitor]

Can confirm master is stable as a rock.

Cool yeah I built master just now and no problems so far

Hello!
I get this error when doing blocknotify.

~$ Failed to bind to socket in open_unix_client
Closing file handle 5
Failure in open_unix_client from notifier.c main:50
Failed to open socket: /tmp/ckpool/stratifier

What could be the problem?

Make sure /tmp/ckpool/stratifier exists. It's a socket opened by ckpool. Probably also need to make sure the user running bitcoind has access to that socket. This may not be the case especially if bitcoind is running as a service but you're running ckpool from command line.

One of 2 specific things:
1) your pointing the notifier at the wrong place
2) the notifier doesn't have privs to access it

... though this answer is basic linux 101.
CKPool is not a point and click pool.
You do need to know what you are doing and a lot about linux and system management to use it ...

WBF1, Kano

Many thanks!  There was insufficient privileges.

If mining w/ ckpool via -A does found block get awarded to address in bitcoin.conf or ckpool.conf

And - can everyone stop mining for ten minutes so I can test my rig.

Thanks!

I believe ckpool.conf, but you can just make them both the same to be certain.

Is there anything built into notifier to notify a remotely running ckpool of block changes? or would I have to set up the remote machine to execute notifier locally via ssh? Also, if notifier runs once from a local bitcoind, will ckpool grab work from all listed bitcoinds? And what happens if notifier runs between block changes? anything catastrophic or just gets new work more often?

No. Yes. No. Nothing. Yes.

What do the values for mindiff (in ckpool.conf) mean? "mindiff": 1 -> if I set that to ten does that mean 10 zeros min prepending the hash?

Is there any feedback or insight on manipulating mindiff  - is there any benefit for a small pool?

Thanks,

It's the minimum difficulty shares of work that will be sent to workers.

So the difficuly is ~158B. If I raise the mindiff in ckpool is there any benfit towards increasing the likelihood of mining a block? Why is the mindiff set to 1 is that only for the purpose of payment for shared pools? Sorry if I am lost on this.

This is a fundamental truth that everyone needs to understand: Nothing you do makes your likelihood of mining a block higher except for increasing your hashrate. Diff is just feedback for miners. Diff 1 is suitable feedback for only the very lowest speed mining hardware (such as the old ASICminer usb sticks).

If I'm not mistaken, ckpool adjusts difficulty per user hashrate. There's probably a description on solo.ckpool.org or kano.is (the two most prominent pools I know of using ckpool backend).

So what is the point for mindiff? I am just trying to understand all the settings. I am running ckpool locally, just getting started in bitcoin. And interested in the concept as a social and economic disruptive technology.

mindiff is the bottom limit for the vardiff calculated by the pool.

read about vardiff here: http://give-me-coins.com/support/faq/what-is-vardiff/

(also this is getting a little off topic. Might want to post a new thread for non-ckpool-related questions)

Hello.
The maximum number of miners can be connected to a ckproxy?
