P2Pool Setup help

[HammerHedd]

As more and more people come over to Darkcoin, presumably more and more people will want to set up a pool of come sort. P2Pool is really easy to set up, but there are some glitches.

I learned a lot about setting it up from Chaeplin, who ported P2Pool to Darkcoin. Unfortunately for the search engines, most of it was in PMs, as the Darkcoin announce thread is already a raging river.

So, I'm starting this thread to help out anyone who is having difficulties with P2Pool. I'll try to get chaeplin over here as well, as he knows far more than I do about it. Also, I hope those of us running a P2Pool can use this as a forum for discussing new additions, etc.

Because I do not have a dedicated miner I more often then not use a MPOS pool.
If I ever purchase one, I'll be using P2Pool. Reason I don't now is because of the 24 hour build up.

P2Pool is great though because you theoretically get payed more then a MPOS pool. (P2Pool receives transaction fees) As well as never having to pay a withdraw fee or worry about a website's front end going down.
All in all if you have a dedicated miner you really are hurting yourself if your not using P2Pool.

And have been through a lot of lows and highs ^^
Can propably help out...

 

[n00b_miner]

Great idea. I'll also put forward some help - I run all the pools at p2pool.n00bsys0p.co.uk, and it's given me a lot of experience very fast!

 

[HammerHedd]

Awesome! Here's something strange that I found out recently:
I ran darkcoind with daemon=1 and P2Pool wouldn't transmit pool fees - when I took it out of the darkcoin.conf, the pool fees transmitted again. Anyone else have this happen?

 

[vertoe]

Can you be more specific? What do you mean by transmitted? You did not recieve any fees?

Recieving fees is as random as finding blocks in p2pool that's why sometimes you might not get any at all. Every share on your node will be submitted to the sharechain. If your pool fee is 1%, then the chance for each share is 1% to get credited to the node wallet instead of the finders account.

It's all about luck,

 

[HammerHedd]

I realize that... However, each time a block is found, a p2pool operator would get a fee (mine was set at 0.5%). The strange thing that happened was that although it was showing that the pool collected a 0.5% fee, it would not send the fees collected to the specified address. The address was showing correctly on the stats page, but showed 0 collected per block. After messing with it a bit, and working with chaeplin, we figured out that for some reason having

daemon=1

in the darkcoin.conf file caused it to not send the accumulated transactions. I haven't played with it again to see if I can make it fail, but I was curious if anyone else had that experience.

Also, I'm not sure I follow what you are saying about the pool percentage. As I understand it, a pool takes a set percentage from each miner when there is a block found. The chance is in the block being found, not in whether or not the pool takes the percentage. Or perhaps I'm just reading it wrong.

No, its not. It's like I said, see this: https://github.com/forrestv/p2pool/issues/159#issuecomment-33346993

Ha! I'm glad I stated this thread, then. I've learned something new. What a fascinating way to do it! So p2pool really doesn't have fees, per se - it's a whole different method of calculating it. That's probably something that could be better explained to the average miner (and some operators!)

 

[vertoe]

I've been mining and operating P2Pool for so long now and you only get the interesting infos if you either read the source code or talk to some very enthusiastic devs.

I found out about the fees because one of my nodes didnt pay any fees to my wallet and I thought it was a bug... well it was just bad luck.

 

[chaeplin]

Fee charged like this.
P2pool change worker summited address to fee payout address.
So it's luck.
That's how fee payout address is included in to share chain.

This is my miner pointed to 100% fee solo node.

p2pool use this method to collect fee.

 

[coffeeblack]

I'm getting nothing but stale/orphaned shares on my p2pool node. What darkcoind version are people running? I've reverted to many of the latest commits and still not any closer to solving this. Ubuntu 12.04 all ports forwarded correctly

 

[HammerHedd]

Are you running a 32-bit OS? I did that, and it wrecked me.
Type

uname -a

And see what you get. If it doesn't say "x64", it might be because you have a 32 bit system.

 

[coffeeblack]

32bit
I'll give 64bit a go

 

[coffeeblack]

EDIT: Nevermind, 64bit seems to have fixed it

Here's a question. I'm compiling on Debian Squeeze. Wallet set up and fine. Going for the p2pool software.

gcc: readline/libreadline.a: No such file or directory
gcc: readline/libhistory.a: No such file or directory
error: Setup script exited with error: command 'gcc' failed with exit status 1

It seems like the most current libboost I can getis libboost1.42-all-dev.

Any Recommendations?

do not run make !!

run "python run_p2pool.py --help"
to check environment.
If it shows "usage ~~~ "
You are ready.

Compile subsidy and hash module.

• apt-get install libboost1.48-all-dev python-dev
  
  
• git clone https://github.com/chaeplin/SUBSIDY_FUNC.git
  
  
• git clone https://github.com/evan82/xcoin-hash.git
