[1500 TH] p2pool: Decentralized, DoS-resistant, Hop-Proof pool

[ancow]

How to update?!

Just:

1- cd ~/p2pool ; git pull
2- stop P2Pool
3- start P2Pool

Since Python doesn't need explicit compilation, yes.

[spiccioli]

Huh!?!?! Whats going on here? Pool: 10458MH/s ? Pool stales: 48% ?

Updating and restarting P2Pool seems to fix it. Several users had this problem, and I'm looking into it right now. Will post more updates soon.

forrestv,

are split chains a waste of mining power?

what about forcing a minimum/maximum version control for all p2pool.py instances sharing the same share chain?

forrestv,

As far as i know no. If the splitted chain find a block, it will be split between submitted shares in the splitted chain. Just, you are mining in a pool with 10ghash

[forrestv]

FEATURE REQUEST: Could P2Pool load config values from a file, and accept a parameter to tell it where to put its data? This would be nice to have, instead of passing a massive long command line to it.

It isn't documented well (yet), but you can use @FILENAME to make P2Pool load options from that file. File contents would be like:

Code:

--net litecoin
-n 1.2.3.4

Accepting a parameter for data files is done as of https://github.com/forrestv/p2pool/commit/ff2a677f .

[Frizz23]

just use --merged http://user:pass@ip:port

Tested with latest version from git and also with forrestv-p2pool-5293db4.


[Edit] Maybe that's because namecoind is still downloading blocks?
[Edit2] No, thats not it.

[Regex]

Sry to bother, one noob question: How do you guys actually see, when p2pool found a block? Are they listed anywhere?

Also, do you get instant payout after a block was found? Cause I didn't get any payments yesterday when you guys where screaming "27 blocks in 20min now!!1", but later I saw a lot of transactions from p2p. How is that working exactly? (I am aware of the xx blocks it needs until the mined coins can be used, that's not what I mean).

Thanks!

[gnar1ta$]

just use --merged http://user:pass@ip:port

For merges mining, I get this error messages:

Did you create a bitcoin.conf for namecoind with user, pass, and rpc port?

[Frizz23]

yep.

rpcuser=USER
rpcpassword=PASS
server=1
rpcport=8336


[Edit] I am using Windows. namecoind seems to be a bit flaky. At the moment it hangs at a "namecoind getinfo" ... :/

Some (but not all) appear in the p2pool console output.
Some (but not all) are announced n IRC.

I personally just watch my bitcoin transaction log.  All of them appear there, and yes payments are instant.   They appear in mining or generation transactions (depending on if you are looking in the GUI or the commandline version of the bitcoin application).

If you were successfully mining (and actually found shares) for all of yesterday and did not get several payment transactions, something is wrong.

Just a quick note. You can now find a list recent of P2Pool blocks here:

I have multiple interfaces on a host and I want run_p2pool.py to listen on 9.8.7.6:9332  How do I do this?

Code:

p2pool interface:
  --p2pool-port PORT    use port PORT to listen for connections (forward this
                        port from your router!) (default: bitcoin:9333,
                        litecoin:9338)
  -n ADDR[:PORT], --p2pool-node ADDR[:PORT]
                        connect to existing p2pool node at ADDR listening on
                        port PORT (defaults to default p2pool P2P port) in
                        addition to builtin addresses

worker interface:
  -w PORT, --worker-port PORT
                        listen on PORT for RPC connections from miners
                        (default: bitcoin:9332, litecoin:9327)

                        port from your router!) (default: bitcoin:9333,

  -n ADDR[:PORT], --p2pool-node ADDR[:PORT]
                        connect to existing p2pool node at ADDR listening on
                        port PORT (defaults to default p2pool P2P port) in
                        addition to builtin addresses

worker interface:
  -w PORT, --worker-port PORT
                        listen on PORT for RPC connections from miners
                        (default: bitcoin:9332, litecoin:9327)

I am probably missing some detail.  I've read the manual, etc. 

"connect to existing p2pool node at ADDR listening on"

That's not clear to me. It says to connect to an existing p2pool node.  I'm running p2pool to listen for my miners not to connect to an existing node.

gnar1ta$, it helps if you know what you're talking about.

Wandering Albatross, line 764 of p2pool/main.py has a reactor.listenTCP where you can provide an interface argument, but doesn't. So, wait on forrestv to code the means of changing that via argument or take the initiative.

... New work for worker! Difficulty: 2.785534 Share difficulty: 424.797691 ...

I think I know what "Share difficulty" is.  What's "Difficulty"?  Is that the miner's criterion for a "mini-share" to pass to p2pool?

Code:

... New work for worker! Difficulty: 2.785534 Share difficulty: 424.797691 ...

I think I know what "Share difficulty" is.  What's "Difficulty"?  Is that the miner's criterion for a "mini-share" to pass to p2pool? 

That is the difficulty of the so-called pseudo share.  P2Pool lies to your miner and tells it to solve an easy share so that your miner finds shares more often than once every 20 minutes (as would happen with the real share difficulty).  P2Pool then effectively ignores (except to calculate stats) any submitted shares that are not good enough for the real share difficulty.  It was done so that you can tell more quickly if your miners are misbehaving.
