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

[GrapeApe]

I've been getting this today "GOT INCOMPLETE BLOCK FROM PEER"
Any clues???

It is normal and harmless when you restart node and download share chain.

I've done that a few times and my miner keeps telling me lost connection at " blah blah" when p2p hangs before it tells me got incomplete block.


p2p freezes says processing shares from blah blah, my cpu spikes to 100% (python), a minute or two later the incomplete message and then my miner is disconnected.

so you've never downloaded the complete share chain?

unless your p2pool is on a ramdrive and not backed up, you shouldnt be downloading the entire share chain every time you restart (unless it's been ~2 days since you last ran it)

Yep every time I restart p2p it downloads the shares. I am just running p2p through the ubuntu terminal using "python run_p2p.py" command. I am new to mining and ubuntu so if I'm doing something wrong let me know.

I get an error when I try to make install. So I’ve just been inputting my parameters into the terminal and running python run_p2p.py.This is all very new to me. I have the dependencies.But yes I do download the share chain every time I start p2p.

Is anyone else getting errors like:

2013-05-13 22:24:44.834000 > p2pool.util.jsonrpc.NarrowError: -12345 lost contact with bitcoind

in the new 11.4 and are stuck with p2pool not accepting any shares?

as in:

2013-05-13 22:27:02.755000  Local: 0H/s in last 0.0 seconds Local dead on arrival: ?? ? Expected time to sh
are: ?? ?
2013-05-13 22:27:02.755000  Shares: 0 (0 orphan, 0 dead) Stale rate: ?? ? Efficiency: ?? ? Current payout: 0
.0000 BTC

I'm testing again by copying over all my old data to the the data dir in the new p2pool folder but I'm not sure. I'm also going to try running it for longer.

FYI: windows pre-compiled, doing merged mining with namecoind and I am also continually getting:

2013-05-13 22:27:05.797000 Processing 23 shares from 71.39.52.34:9335...
2013-05-13 22:27:13.082000 > Error while processing Event callbacks:
2013-05-13 22:27:13.082000 > Traceback (most recent call last):
2013-05-13 22:27:13.082000 >   File "p2pool\node.pyc", line 289, in set_best_share

with a whole bunch of lines listed as per the last line.

Edit: watching it. The graph shows my hashrate and that seems to be working fine. Still no shares (0, 0 orphan, 0 dead) and I got a few "punishing share for block-stale detected". Not sure what those are. Also got some "twisted.internet.connectionlost" and something about being disconnected locally. My "dead" on the graph spiked once to 100% for 1 tick. Other oddities include only one incoming peer, when I limited to 8/8. 11.1 immediately connected to at least 3-4 and eventually to 8.


Edit, Edit: So I do have a number under "payout if block were found NOW" so I am thinking everything is working fine, regardless of these weird errors. I understand there are to be errors normally but I was worried since there were errors I was not getting in 11.1

I've never gotten one of these before.

Just means your share has a high difficulty.
On p2pool that's the same as a normal required difficulty share in terms of payment.
Though the information is useful to show you that indeed that share is high enough for the share chain.

The only pool that this makes a difference is the OzCoin Pay on Target pool.
e.g.  [2013-05-13 01:44:55] Accepted 0000103e Diff 1.03M/256 BAJ 0 pool 0
That was worth $10

But on another pool:
 [2013-05-04 02:24:44] Accepted 00000222 Diff 7.86M/12 BAJ 0 pool 2
that was worth ... 1 share

Been running P2Pool for weeks now.  On version 11.4.  Last night windows update ran and now I cant get P2Pool to start.  I just sits at

Testing bitcoind P2P connection to '127.0.0.1:8333' ...

Tried these so far and nothing:
Turned off windows firewall
rolled back windows updates

Any ideas what might be up?  It seemed like bitcoin-qt.exe went too fast catching up on the 50 blocks it missed.  I watched it take a minute or two to get through the first 5 missed blocks and then it jumped to caught up right away.  I had another bitcoin-qt.exe on a separate computer catching up as well and that one took several more minutes to finish getting the 50 missed blocks since 3am when they all rebooted.  Any ideas on what to check next?

I apologize if this has been asked before, if there is an answer somewhere in the 200+ pages please link me.

How do i get this to work with scrypt coins? I can easily get it working with bitcoin but not litecoin or any other variation.

I believe it's in the readme.  I found compiling the latest get to be difficult for litecoin, but if you don't need/want that, the executable works just fine.

Update.  I think I figured out what was going on.  I had limited the connections on bitcoin-qt.exe to 6 to keep latencies low.  I think what was happening is the 6 connection were getting taken up before I started P2Pool.  Strange as I've never had the problem before.  I loosened the connections to 10 and started P2Pool right after the bitcoin client loaded.  Prior to that I always let the bitcoin client load and get all caught up prior to starting P2Pool.  Its working now.  Posting back in case this trips someone else up.

I was about to reply to your previous message with this suggestion.

For reference, I had to configure some of my *coind with 20 connections to make sure P2Pool can connect, I had problems with some alt-coins at 10 and 15.

The log itself is harmless and may mean that the Erupter doesn't support dynamic difficulty (surprising) or that it is overclocked too much and output errors (more likely given the very high values of the hash in your log).

If it's an hardware problem, cool the blade more or slow it down.
If it's variable difficulty support missing or buggy and the rate of share submission puts too much load on your p2pool node, you could try using slush's stratum proxy between the blade and the node to lower the load on it.

I vaguely recall somewhere in the ASICMINER thread, their hardware apparently does getwork diff 1 directly.  If you want to use any other mining protocol or difficulty you need a mining proxy.  I would be curious to learn what kind of work switching latency it is capable of.

^C2013-05-16 13:14:08,478 INFO proxy mining_proxy.on_shutdown # Shutting down proxy...

So looks like we have multiple problems:
Incompatibility no. 1: BE Blade vs p2pool
Incompatibility no. 2: Stratum mining proxy vs p2pool

I can confirm that same device is hashing nicely now with stratum mining proxy at BitMinter.

EDIT: Pasted wrong output from stratum+blade. Corrected

Any suggestions?

[ok]

Blade is working absolutely fine, it's not a hardware problem.

I tried stratum-mining-proxy on my p2pool node (lenny.dnsd.me:9332)

Code:

So looks like we have multiple problems:
Incompatibility no. 1: BE Blade vs p2pool
Incompatibility no. 2: Stratum mining proxy vs p2pool

I can confirm that same device is hashing nicely now with stratum mining proxy at BitMinter.

I have tested an Erupter Blade on my p2pool node and can confirm that:
1. When it connects directly to the p2pool node, p2pool reports a much lower speed than its real 13GH. P2Pool can not keep up with the blade submissions.
2. When connecting through a Stratum mining proxy to p2pool, p2pool continuously disconnects the stratum proxy user, sometimes even denying user authentication to p2pool.

By looking at my server logs, p2pool can not keep up with the number of connections that the Erupter Blade attempts either directly or through a Stratum mining proxy.

Therefore it certainly seems that p2pool is incompatible with both options.
Developers should fix these two incompatibility issues if they want p2pool to succeed and continue to be used with ASICs and more specifically with the increasing number of ASICMiner Erupter boards out there.
Thx.

@ok:

+1

BTW I was reporting incompatibilities of stratum-mining-proxy and p2pool couple of months ago.

I can donate my Blade worktime to developer, if needed, can provide ssh access or something. Please PM.

Good luck with it guys!

[-ck]

As discussed in the previous few pages, there are clearly some stratum issues still to resolve, and scalability issues to cope with ASIC sized workloads. BFL are sending (?have sent) forrestv a 5GH unit which should help drive development of both of these.

Hi guys,
I have priority issue with bitcoind latency.
My bitcoind node is literally flooded by hoax transactions, like this:
https://blockchain.info/tx/7227c9d392166fdcd917f39da2def36bcf69b437d90e349d73a48952c0fbdd69
https://blockchain.info/tx/292d1d7ff7ece8eb67b4bf3c2f523736679c616fce8216bf37ac23edec6e0e03
1 single transaction, nice miner fee included (1.46 USD actually), but it have over two thousands outputs and 100 KB in size! It's like a fishhook, whoever will take it, will loose seconds of latency.

Bitcoind latency is at ~ 4s (I have dedicated server with AMD A10 APU + SSD), for months it was at 0.3s. About 18 hours ago my latency went extremely high up to 7s and till then, network is under attack of these hoax transactions. Exactly same problem has been reported by my collegues at forum.bitcoin.pl. They showed be their stats and same latency issues (bitcoind latency at 3s or worse, like in my case).

My bitcoin.conf:

Code:

(...)
maxconnections=30
blockmaxsize=500000
mintxfee=0.00005

How to filter these transactions?
