I don't know how long you've been running, but shares in P2Pool are much more difficult than shares in a normal pool. You don't have a very powerful card there, so it might be that it's taking a while to find a valid share.

Let it run for a bit and see if you find a share.

Exactly.  In case anyone else is wondering.  At difficulty 170 it takes ~ 730GH to find one share (remember that is an average each share may vary by as much as 30% to 300% of that number).

So 730GH / 0.23 GH/s = 3175 seconds ~= 59 minutes.

At 230MH/s it will take ~ 1 hour to find a share.  Due to variance it routinely could be anywhere from 30% of that (~20 minutes) to 3x that (3 hours).

Just one more probably stupid question  Tongue

Let's say you find a share, then you close the p2pool software and your bitcoind client. Do you still get the payout when the block is found?? I have not had time to read up on how all this really works.

That will work just like any other PPLNS pool, so you will get paid unless the pool is really unlucky and your share is too old.

Pay Per Last N Shares. Similar to proportional, but instead of looking at the number of shares in the round, instead looks at the last N shares, regardless of round boundaries.

Yes, if a block is found within the next 24h.

That own efficiency thing is confusing ...
I have seen numbers varying from 60% to 120% in that column.
And if I understand it correctly, if you have 60%, you will be getting 40% less BTC per GPU hash than an average miner on p2pool.
So 50% of people who see <100% efficiency, have an incentive to leave for a regular pool.
Those that remain will again compete against one another, and 50% of those will leave etc...

I just cant get this running.

I'm using win7:
Starting bitcoind
then run_p2pool.exe test test (test is username and password)
cgminer.exe -o http://127.0.0.1:9332 -u test -p test

Looks like cgminer is running fine, but i dont get any shares in p2pool window

P2Pool's difficulty is currently about 240. It might take a while to get a share depending on how much hashing power you have. See http://www.alloscomp.com/bitcoin/old_calculator.php

If your efficiency is that low, and it will take a day or two to level out, stated here https://en.bitcoin.it/wiki/P2Pool#Stales it's usually due to your miner or network configuration, which if not properly set up, doesn't matter what pool your mining on, your losing BTC.

Nope, my miners works fine with regular pools.
And most of the time I see efficiency >110%.
But if I have 110%, some other guy (probably you) has 90%.

Are you refering to your efficiency number given by the pool or the miner?

Pool of course

Code:
2012-01-17 18:43:16.670613 Pool stales: 11% Own: 12±3% Own efficiency: 99±3%

Nope..not 90%. I'm sure DeathAndTaxes can jump in with technical details but I'm failry sure even if it was, pool efficiency is an estimate.  It's not like your taking 10% from others to be paid for 10% more work than you submit.

Even if the problem doesn't exist, it SEEMS to the unexperienced user that it exists.
If efficiency number isn't accurate, don't display it, as it scares people off, produces confusion, and prevents widespread adoption of p2pool.

I am mining at 200Mhash as well, takes 1-3 hours per share. its kinda random, sometimes i get 2 in 10 minutes.

Just setup namecoind like you did bitcoind with a namecoin bitcoin.conf similar to this:

Code:
rpcuser=nmcuser
rpcpassword=nmcpass
rpcport=8335
port=8334
daemon=1

After the block chain is downloaded restart p2pool adding this to what you already have:

Code:
--merged-url http://127.0.0.1:8335/ --merged-userpass nmcuser:nmcpass

A note on merged mining: Merged mining with p2pool is effectivley solo namecoin mining - no shared reward, 50NMC when you find your own block.

I asked this in another thread, but got no response.

Is there any way to monitor the workers on your p2pool? Let's say I want to run a small pool that uses p2pool. The miners would point their workers to me with whatever address they want payment at as their username.  That is easy enough for bitcoin payments.  However, I can't figure out any way to determine how much to pay those workers should be paid if I find a block on the alt-chain. I was hoping for something like http://localhost:9332/local_workers
