One more thing - if you're running Antminer S2, you're losing about 10-15% of your hashing on p2pool.  It's a known issue, and hopefully one that will be corrected (either by Bitmain directly, by one of the cgminer developers, or the p2pool developer).

That payout value will continue to rise until 8640 shares have been put on the share chain since you started on the pool.  From there it will remain pretty much normalized at that level.  Remember, too, that this is a PPLNS system.  You could shut down your miners now and still get paid (assuming you still have valid shares on the chain when the next block is found).

Finally, p2pool will be considerably more variant than where you were mining.  There will be times when no blocks are found for a few days, but then 4 will be found in a day.  For a great comparison of payouts of p2pool vs BTCGuild vs Eligius, check out this thread: https://bitcointalk.org/index.php?topic=416933.0

Thanks for that link.... interesting to say the least. If I am to rely on it, its p2pool almost always the winner. Its just hard to see it when a block comes and you get 20 bucks.
I will eat the daily income to see how the longer haul here works out. Also I have 1 S2 in the mix, and it mostly stays at 1010 or there about according to the stats??? once in awhile it will go into the 900s but in an hour or so I will see it back up.... And I noticed the exact same thing with the other pools. So I can not see the big difference. I am sure all of everyones extra hashing can only help us all in the long haul...

Interesting... virtually everyone who owns one has seen and reported at least a 10% loss.  There's been plenty of discussion on this - kano has been working to release a stable version of cgminer for the S2 that plays nicely with p2pool... Bitmain has been sent a ton of data and has replied that they indeed intend to support p2pool and have their core devs working on it.

Anyway, stick around.  At first the variance is hard to accept, especially if you're coming from "the pool that shall not be named," but in the long run, I think you'll like it here.

OK - I have faith...... maybe a little less money to pay my electric.... But I will have faith. You all seem like great peps and this feels like the way to go.
Sorry if I have taken up a lot of the board this afternoon with my nonsense.... But I needed this little bit of help to help me make my mind up and not just give up on the p2pool.....

Thanks again.

Just curious, I run all antminers....S1 and S2  total 4 TH.... I get 4 TH on my own pool and seem to have no issues?
It seems like I hear a lot of people having problems with the S2's??

S1's work fine with p2pool, but S2's lose between 10%-15% hash rate.......

Not to mention the valid blocks being discarded.......

That's what we are here for mate.
I took 35gh/s to p2pool and have since added another 200, my payouts have been less frequent but I've been very happy with the value of them. I feel like I am getting much more than when I was hashing on other pools.

(cross post from the other thread, which some of you might find useful)

Alrighty, I've implemented the donation tool API using simple GET protocol.

http://blisterpool.com/p2papi explains how to do it all.

A couple of people asked for this, not 100% sure why but off the top of my head if you're a business you could automate payments via script pretty easily, and secondly if you're a p2pool node operator and want a relatively easy way to drum up p2pool donations you can add a simple form (get, not post) to your front end that calls upon this api.

At the moment if you create a donation using the API, you can supply an operator_email field and a tip_address field. This is if you want to route donations through this tool (for example, you don't want to write your own interface). If someone comes across your node and wants to donate, instead of sending them to my page you can just create a form which makes the request on their behalf, put in the normal fields, put your email address and your tip address in too, then send the response back to the user. Any tip gets split 50/50, and I pay all the network fees from my portion.

I've tested it and it seems to be working as intended...any problems let me know.

Peer =148.251.238.178:18702 is causing bitcoind to go out of sync, 0 hours behind..... lying about blocks

Is there a way to block these getaddr.bitnodes.io:0.1 clients from bitcoind, or do one have to block ip after ip from firewall?

Not sure but, it seems to cause orphan and dead shares while this happens..0 hours behind....

As far as I know, you can only block them by setting up a whitelist of connections to use, so only setting up connections for specific peers. 
Use "connect" to establish a list of trusted peers, but then you're only locked to those peers which has its pros and cons.

Quote
-addnode=<ip>          Add a node to connect to and attempt to keep the connection open
 -connect=<ip>          Connect only to the specified node(s)
 -seednode=<ip>         Connect to a node to retrieve peer addresses, and disconnect
 -externalip=<ip>       Specify your own public address
 -onlynet=<net>         Only connect to nodes in network <net> (IPv4, IPv6 or Tor)

-connect method would be nice if I only knew how to connect to p2pool node, not sure what happens if bitcoind is started up witout connect settings and then p2pool brought up - then change the config to connect=specified hosts and reboot bitcoind.

It can be that if a block is found it cant be submitted to bitcoind..

Installed and configured iptables and now it stays synced..

I have 4 batch 1 units that will go live on my node upon arrival, Bitmain has stated that they will work to make them play well with p2pool, I've also started a bounty for forrestv to get S2s & S3s working correctly...

I think the connect param only applies to peer connections, not RPC connections from the same machine. Worst case scenario, you could allow 127.0.0.1 (which is localhost).

The good news:
I managed to make a stratum proxy that works with p2pool.

The bad news:
It looks to me like the S2s can't respond quick enough to the restarts from p2pool.  That causes rejects.  If the difficulty is too low, it gets out of hand, where the shares coming from the S2s are from prior jobIDs, as many as two or three back.

I'm watching the data flow through real time, and shares submitted 1-5 seconds after the restart request (with the new jobID) are rejected because the jobID is the wrong one.

Other things of note:
- It'd be useful if p2pool returned some indication as to what was wrong when an item is rejected.  I'm going to have to track jobIDs myself to visually indicate if it was rejected because of a bad jobid.
- The "id" in the response from p2pool doesn't match the "id" from the sender.  The stratum specs are a bit vague, but it seems to me the response "id" should be the same as the sender id.  Instead it seems to be an incremental number for that connection.

More to come.

I'm watching my ants go through my proxy to Eligius now.

Two big things that are different between Eligius and p2pool:

- when Eligius sends the "new job info", in most cases it doesn't tell the miner to restart the work (p2pool does all the time)
- the Ants still take a while to switch over to the new "job id".  However Eligius accepts the work from old jobids anyhow (p2pool rejects them all the time)
