Trying to investigate a luke-jr claim from IRC:

Quote
<luke-jr> sipa: already we have p2pool + height-in-coinbase-bitcoind making ver=2,coinbase=no-height blocks

The dev team is working on BIP 34 - height in coinbase, and if what luke-jr says is true, then there is a buggy p2pool implementation out there generating invalid version 2 blocks.

For those hackers out there, this is the BIP 34 change:

Code:
-    pblock->vtx[0].vin[0].scriptSig = (CScript() << pblock->nTime << CBigNum(nExtraNonce)) + COINBASE_FLAGS;
+    unsigned int nHeight = pindexPrev->nHeight+1; // Height first in coinbase required for block.version=2
+    pblock->vtx[0].vin[0].scriptSig = (CScript() << nHeight << CBigNum(nExtraNonce)) + COINBASE_FLAGS;

All that is required is that nHeight be the first element of the coinbase.

Just started using p2pool again today and I have a quick question. Does the --p2pool-node flag support DNS lookups or can it only do IP addresses? I have a friend nearby that I'd like to be always connected to, but he has a dynamic IP.

To everyone and anyone who might be jumping back on the bandwagon, make sure you're using the latest version of p2pool!  Don't dust off the version you had when you used it last!!

M
Yeah, I know; I'm on an entirely new Ubuntu install so I had to download the newest version. Does anybody know the answer to my question though?

hmm, any ideas why my systems on my switch get 50% rejected on p2pool (they were originally on a hub and I thought it was from all the collisions, that shouldnt be as much of an issue now?)   it  doesn't happen on other pools

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

Doesn't look like it worked. Maybe we could make that a feature request? However, I looked through my address file and your IP is in there.

Came back to p2pool today after a while of being gone. Added 1.9ghash to the pool. Smiley I just want to confirm that the binaries in the first post are up to date. I'm running p2pool ver 3.1, and want to make sure I'm on the right version.

Also, what was the edit to change the frequency that p2pool displays information. Every 3 seconds is just too freakin' often.

Hi, been on p2pool for a week now, 24/7. Just heard of some kind of lottery, can someone explain this to me as i was 4???

I've seen my address with a number in front of it, 16.whatever, on a sendmany patron whatever url... what is that? Is there some extra earning on p2pool that i'm not receiving? i only get what i mine, the shares i submit, not a cent more... i like p2pool even though i might be getting more on other pools. i have 450Mh/s, sometimes on p2pool window i get as low as 200, others i get 500.

Just interested in knowing if there's some more to gain on this pool, and what am i doing wrong if i'm not getting any...

Thank you.

Thank you.

With only 450mhash, more than likely you're just seeing share balance. If you've even mined with a pool that offers proportional mining, then you'll know that there is not just the variance of finding blocks for a pool, but also the variance of getting shares for your miners. It just happens that at that particular time during the round, your miner hadn't found its share of shares, so to speak. Over time, it all balances out just like block finding.

Go to your stats page:

And see how much you share/earn.
Patron sendmany is a donation for p2pool miners, by default it have cutoff for smaller ones (read wiki).

Hi, my average earn is about 0.0627 per block, I didn´t say i don't get payed.

I don't understand that "cutoff" and what happens with smaller miners like myself. And if there's a lottery how does it work?

Thanks for your answers.

First of all I appreciate all the amazing information within this thread, even though it is nearly impossible to find with so many pages. None the less, thanks.

So I spent a lot of time confused and trying to learn and received little (but useful) input in the newbie thread I made here :

https://bitcointalk.org/index.php?topic=97288.0

You can read it to get an idea of what I've gone through, but here's where I'm at now:

http://i.imgur.com/AG7Qc.png

Glad to say I busted the last block, at least that's what I take it to mean. So am I finally getting the picture? One thing I don't understand, are shares based on an average in the past 24 hours or so? Is that why my payout keeps going up without discovering new shares rapidly? I assume there is no significance of finding a block since I am in the pool (which seems effective even for my low end machine GPU Nvidia). I am enjoying the learning experience about bitcoin and to use it.

Any advice would still be great, thanks!

BTC Long.

When it says "GOT BLOCK FROM PEER," then a different node solved the block. When you solve, I believe it says "GOT BLOCK. PASSING TO BITCOIND."

hmm, somewhere around .8, probably.

my stats are @

http://nogleg.com:9332/static/graphs.html

notice the DOA went up a lot there, that's when i added a computer behind my switch.  it gets about 50% DOA, any computer behind that switch gets 50% DOA... well, they're DOA to P2Pool, but I've had them solve blocks.  essentially cheating me out of that 500mhash or whatever.

on maxbtc, the reject rate was maybe 1 every 2500 shares or so.  dunno what the deal is with that

like this:

http://nogleg.com:9332/static/share.html#0000000000000261a8fac12041ebafe2185f671f8ce012b32f459b1d5133f778

solved a block.  but it was orphaned by p2pool, so it doesn't appear in the blocks solved list.

orphaned in favor of this:

http://nogleg.com:9332/static/share.html#000000000020331b3963d9aeb7ce135472295f00b4f3966b5a1ee47869aff119

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

Hm, so do I understand right that "4.8"g/h is equal to 4,800 mh/s?  Or 480mhz? Or.. math isn't my strong suit.

I am approaching .33 payout per block with my 560 ti, pretty pleased for not having any specific hardware. Fun.
