I thought I had it figured out. But P2pool hasn't worked in my case:

Steps I followed are:

1. Ran Bitcoin client with RPC interface enabled (created bitcoin.conf and put 'rpcuser', 'rpcpassword' and 'server' in there). Let it update the block chain.
2. Ran run_p2pool.exe
3. Ran cgminer.exe with -o http://127.0.0.1:9332 -u -p

run_p2pool seems to get stuck and 'cgminer.exe' complains: "No servers were found that could be used to get works from.".

Can anyone help?

It sounds like p2pool isn't connecting to bitcoind. You have to connect it by by using the username and password you set up in bitcoin.conf. Run_p2pool.exe and then connect cgminer using any user pass - no the ones you set up in bitcoin.conf.

I actually used : run_p2pool.exe

Initially, run_p2pool seems to be communicating with bitcoind. But after a while, there are no messages on the console. On the cgminer console, first it says "Pool 0 not providing work fast enough", then after a while I get a message saying "Pool 0 http://127.0.0.1:9332 not responding". I checked the firewall. All the ports are opened appropriately. Bitcoin-qt has up-to-date block information as well.

Well, I know I won't be able to mine until the block chain downloads completely, but I'm trying to figure out why p2pool can't talk to bitcoind. I would assume it should be able to even if there are still blocks to download.

I'm trying to get P2Pool going, but I'm running into problems:

1. bitcoind is running and downloading the blockchain. getinfo confirms it's currently at 140k blocks.
2. I run p2pool and get output like the following:

Code:

I assume this means p2pool can't reach the bitcoind instance, but it's there and running. Any ideas?

Just wait until the blockchain finishes downloading.

Am I correct in assuming that, when using the `-a` flag to specify a payout address, that the provided address need not be provided by the instance of bitcoind that p2pool is connected to? (i.e. it can be from another wallet on a completely different computer?)

Yes.

Also, if anyone would like an address to test this with, I'll happily provide one Wink

I just moved my main miner over to p2pool and it's running great.

Just as a backup, I am trying to install p2pool on another system. It seems to be running, but I am getting a lot of failures. I get this over and over.

EDIT: Ahaa! Namecoin wasn't running and I had it set to merge mine. That error message could have been more helpful though.

What would be really nice would be to bundle p2pool with bitcoin, so as long as the client (or bitcoind) is running p2pool would run. Not to mention providing it with a gui interface in bitcoinQT would probably help adoption.

Does bitcoind have to be caught up downloading the block chain before starting P2Pool?

Yes

Is there a convenient way to ensure this happens unattended?

I'm not currently on p2pool. I currently have my (linux) mining rig configured to run a script on boot that automatically gets cgminer going pointed at the right pools. So, if the power goes out while I'm away, and then comes back on, everything (in theory), just fires right back up again.

So, if I were to switch to p2pool, I'd need some way of automatically launching bitcoind (I guess), monitoring it to see when it's caught up, and then launching the p2pool client.

Or, better yet, to make things easier on everyone, it would be nice if the p2pool client managed that itself so that one could launch it right away and it would monitor bitcoind and not start actually mining until the time was right. But, not knowing what goes on between bitciond and p2pool, I admit that that might not be technically feasible.

I think its fine to launch p2pool even while bitcoind is out of date. Your shares will be rejected until it gets up to date, but once its up to date it should start working fine.

I tried to drop my 2.5 gh/s minecart in, with the same version of phoenix but running the last release of linuxcoin. I'm getting about 30% - 50% reject rate on all 7 gpus (3x5970s & 1x5830) Same miners pointing at Slush and I'm down at 1% reject rate. Does the P2P client have issues with nodes that have too many GPUs? Maybe I need to update the ATI drivers...

I run a single rig with 5 GPUs and phoenix and get about 5% reject. Check your AGRESSION option. It needs to be lower for p2pool in order to get lower stales. I was getting 20-30% as well and dropped the AGRESSION from 9 down to 7 and reject rate dropped like a rock. I don't know why this is necessary, but it seems to be.

Thanks, dropped aggression from 11 to 8 and no rejects yet. It did lower my hash rate by about 2.5% but that's better than 50% rejects.

I'm a little confused about where the payments come from though... Does the p2pool client force multiple payments from the block solver's bitcoin client to all miners in the pool? Is another bitcoin client built into the p2pool binary?

The found-block directly includes the appropriate payments in the coinbase (the transaction that generates the 50 BTC). Instead of the 50 BTC going to one address, it goes to all of the addresses of people that have mined shares in the last N shares (usually 8640) relative to how many shares they have mined.

See here for an example:

http://blockchain.info/block-index/856135

(see the "No Input (Newly Generated Coins)" transaction)

Ok, that's really cool, I didn't know bitcoin allowed multiple addresses for payout of the found-block.

So, I've got my 2 Windows miners(1x2x5870 & 1x2x6970) chugging along at about a 1% reject rate with phoenix 1.7.5. I tried to drop my 2.5 gh/s minecart in, with the same version of phoenix but running the last release of linuxcoin. I'm getting about 30% - 50% reject rate on all 7 gpus (3x5970s & 1x5830) Same miners pointing at Slush and I'm down at 1% reject rate. Does the P2P client have issues with nodes that have too many GPUs? Maybe I need to update the ATI drivers...

I'm running p2p client on a central machine in my network; I would try running another p2p instance on the minecart but I'm running the OS off a 4gb USB stick and I'm not sure it could handle the current size of the Bitcoin blockchain.

dont see any problem there
work is restarted when a share is found by others - about once in 10 seconds
the accepted shares reported by the miner are low difficulty - ~1 , this can indicate if you have any problems with rejects
the actual shares that count are reported in the p2pool client

The "issues" thing on github is for bugs. What you've put in your issue is more of a question and should be asked here.
